Strapi Suite

Model Context Protocol server for Strapi v5 Expose your Strapi instance to LLM clients (Claude, Cursor, any MCP-compatible) for generic content management, visual layout configuration, schema authoring, media uploads and GraphQL testing — with native Strapi API token auth, multi-layer rate limiting and a forensic audit trail for every operation.

TL;DR

Drop this plugin into any Strapi v5 project, create an API token, point your MCP client at /api/strapi-mcp-suite/stream. Your LLM can now read/write entries, reorganize admin UI layouts, generate components and content-types (opt-in), upload media (opt-in) and execute GraphQL queries (opt-in) — all through native Strapi APIs (strapi.documents(), lifecycle hooks, validation, draft & publish).

The plugin ships with hardened defaults: path traversal blocking, SSRF protection (AWS IMDS / RFC1918 / DNS rebinding), rate limiting in 3 layers (per-token / per-user / per-IP), a fail-closed production mode for schema authoring, and a forensic audit trail (token lifecycle + every operation) with delete-permission enforcement on tokens.

Features

Built-in tools (33 total, organized by capability)

Category	Tools	Notes
Content ops	list_content_types, get_content_type_schema, find_entries, get_entry, create_entry, update_entry, delete_entry, publish_entry, unpublish_entry	Generic CRUD on any content-type. Delegates to strapi.documents(). Always available.
Visual layout	get_visual_layout, set_field_layout, set_field_metadata, set_view_settings	Modifies the Content Manager UI config (widths, labels, ordering). Stored in strapi_core_store_settings. No restart required.
Schema authoring	list_existing_schemas, read_schema, validate_schema_proposal, create_component, create_content_type, add_field_to_schema, delete_field_from_schema	Writes .json schemas and .ts stubs to filesystem. Requires Strapi restart for new schemas to load. Gated by SCHEMA_AUTHORING_ENABLED=true. Refused in production.
Media / upload	list_media, get_media, upload_media_from_url, update_media_metadata, delete_media, link_media_to_entry	URL-based uploads. Works with any Strapi provider (local, S3, Cloudinary, R2, etc.). Gated by UPLOAD_ENABLED=true. SSRF-protected.
GraphQL	graphql_introspect, graphql_query, graphql_generate_query	Test GraphQL queries, introspect the schema, generate queries from a content-type UID. Mutations require explicit allow_mutations:true. Gated by GRAPHQL_ENABLED=true and requires @strapi/plugin-graphql installed.
Diagnostics	__health, __list_registered_tools	Health ping (use after schema-authoring to confirm Strapi restarted) + registry inventory. Always available.
Audit	__audit_token_creators, __audit_log_query	Read-only views over the forensic audit tables (who created each token, every tool invocation with redacted args). Requires super-admin. Always exposed but always denies non-super-admin callers.

Extensibility

Custom tools registered from your project bootstrap appear alongside the built-ins:

strapi.plugin('strapi-mcp-suite').service('registry').registerTool({
  name: 'my_custom_tool',
  description: '...',
  inputSchema: { ... },
  handler: async (ctx, args) => { ... },
  testCases: [ ... ],   // optional, run automatically in dev bootstrap
  tags: ['read'],
});

The registry validates structure (snake_case naming, JSON Schema validity, no built-in name collision) and optionally runs testCases to give you confidence before exposing the tool to the LLM.

Requirements

• Strapi: 5.0.0+ (5.45+ recommended for full anti-impersonation)
• Node.js: 20+ (uses built-in fetch, crypto.subtle, etc.)
• MCP client: Claude Desktop, Claude Code CLI, or any MCP-compatible client supporting streamable HTTP transport

---

Installation

pnpm add strapi-plugin-mcp-suite

Strapi v5 auto-discovers the plugin — no config/plugins entry is required. Restart Strapi. You should see:

[strapi-mcp] plugin loaded — endpoint /api/strapi-mcp-suite/stream | strapi=5.46.0 | env=development | schema_authoring=disabled | upload=disabled | graphql=disabled

Developing the plugin from source instead? See CONTRIBUTING.md for the local-clone setup.

---

Quick start

1. Create an API token

In the Strapi admin: Settings → API Tokens → Create new API Token.

• Name: include your email, e.g. [email protected] - mcp client. The plugin uses the email in the name (combined with adminUserOwner) for anti-impersonation and to attribute createdBy / updatedBy in entries created via MCP.
• Token type: Full access (recommended) or Custom with the content-types you want exposed.
• Lifespan: as your team requires.

Copy the token — it's shown only once.

2. Configure your MCP client

Claude Code (CLI)

Edit ~/.claude.json or your client's config:

{
  "mcpServers": {
    "strapi-local": {
      "url": "http://localhost:1337/api/strapi-mcp-suite/stream",
      "headers": {
        "Authorization": "Bearer YOUR_TOKEN_HERE"
      }
    }
  }
}

Claude Desktop (Windows / macOS)

Claude Desktop only supports stdio transport, so you need mcp-remote as a bridge. In %APPDATA%\Claude\claude_desktop_config.json (Windows) or ~/Library/Application Support/Claude/claude_desktop_config.json (macOS):

{
  "mcpServers": {
    "strapi-local": {
      "command": "npx.cmd",
      "args": [
        "-y",
        "mcp-remote",
        "http://localhost:1337/api/strapi-mcp-suite/stream",
        "--header",
        "Authorization:${AUTH_HEADER}"
      ],
      "env": {
        "AUTH_HEADER": "Bearer YOUR_TOKEN_HERE"
      }
    }
  }
}

On Windows, use npx.cmd (not npx). After editing, fully quit Claude Desktop (system tray → Quit) and reopen.

3. Try a first tool call

In Claude:

"List the content types in my Strapi instance and show me the fields of each."

This invokes list_content_types and you should see your CTs (article, author, etc.) with their attributes.

---

Configuration

All configuration is via environment variables. See .env.example in the repo root for the complete annotated list. Quick reference:

Security model

The plugin is designed assuming the LLM is untrusted input — prompt injection, poisoning, or jailbreak could turn it into an adversary. Defenses:

Authentication & granular permissions

• Native Strapi API tokens — no custom auth scheme to break. Reuses Strapi's hashing and storage.
• Granular permission enforcement — Custom tokens must have plugin::strapi-mcp-suite.stream.handle explicitly marked. Tokens of type Custom without the MCP permission marked are rejected with 401 Custom token missing MCP permission. Full Access and Read Only tokens pass by design (broader scope).
• Best-effort attribution — if the token has adminUserOwner populated (only happens for kind='admin' tokens with the experimental features.future.adminTokens flag), the plugin attributes createdBy/updatedBy on entries. For standard content-api tokens, attribution is null (see Known limitations).

Path traversal (schema authoring)

• All UID segments validated against ^[a-z][a-z0-9-]*$ before being used in path.join.
• Defense in depth: assertWithinAllowedRoot() ensures the resolved absolute path is under src/api/ or src/components/.
• writeFiles performs a final containment check before any disk write.
• Backups go to .strapi-mcp-backups/ (gitignored by default), preserving relative paths.

SSRF (upload_media_from_url)

• Protocol allowlist: only http:// and https://. Blocked: file://, gopher://, javascript:, data:, etc.
• IPv4 blocklist: loopback, RFC1918, CGNAT, link-local (including AWS IMDS 169.254.169.254), Alibaba metadata (100.100.100.0/24), reserved ranges.
• IPv6 blocklist: ::1, fc00::/7 (ULA), fe80::/10 (link-local), multicast, IPv4-mapped variants.
• DNS rebinding defense: hostnames are resolved and all returned IPs validated.
• Redirect chasing: fetch uses redirect: 'manual' and re-validates each hop (max 3 redirects).
• Per-environment override via UPLOAD_URL_ALLOWED_HOSTS (strict mode) or UPLOAD_URL_EXTRA_BLOCKED_HOSTS / _CIDRS.

Rate limiting (3 layers)

Layer	Default	Defends against
Per-token (SHA-256 of bearer)	60 req/min	Leaked token abuse
Per-admin-user	120 req/min	A user creating N tokens to bypass per-token
Per-IP	300 req/min	Independent secondary layer; handles NAT'd teams

Each layer is a sliding window. Any layer hitting its limit returns 429 with Retry-After and details.layer identifying which limit fired.

Production guardrails

• isProduction() is fail-closed: if NODE_ENV is not explicitly development, test or dev, schema authoring is refused. Docker containers without NODE_ENV get safe defaults.
• Schema authoring tools are hidden from tools/list unless SCHEMA_AUTHORING_ENABLED=true. Even if enabled, writers refuse in production.
• GraphQL mutations require explicit allow_mutations: true per call.
• Destructive operations (delete_*) require confirm: true.

Audit trail (v0.4.0)

The plugin maintains two internal tables (hidden from Content Manager and Content-Type Builder, not exposed via REST/GraphQL):

• mcp_token_audits — one row per API token. Captures creator_id, creator_email, created_at_real, and on deletion deleter_id, deleter_email, deleted_at. Tokens that existed before the plugin was installed are backfilled with creator_email='unknown' and is_legacy=true.
• mcp_op_logs — one row per tools/call over the MCP endpoint. Captures: tool_name, status (ok/error), duration_ms, token_id, admin_user_id, admin_email, ip, user_agent, args_redacted (args with secret-shaped keys replaced by [REDACTED]), result_summary (small extraction — documentId, count, uid — never the full payload), and error_message for failures.

Delete-permission enforcement on admin::api-token: a beforeDelete lifecycle hook blocks deletion unless the caller is the original creator OR a super-admin. Legacy tokens require super-admin. The deletion itself is recorded by afterDelete, so even authorized deletions leave a trace.

Retention: op-log is bounded by both an age window (MCP_AUDIT_RETENTION_DAYS, default 90) and a row cap (MCP_AUDIT_MAX_ROWS, default 100k). A cleanup job runs every MCP_AUDIT_CLEANUP_INTERVAL_HOURS (default 24) in batches of 1000. Setting either limit to 0 disables that pass — useful for tests, not recommended in production.

Querying the audit:

// Tool: __audit_token_creators
// Args: { include_deleted?: boolean = true, limit?: number (cap 500) }
// Returns: { count, tokens: [{token_id, token_name, token_type, creator_id, creator_email, created_at, deleter_id?, deleter_email?, deleted_at?, is_legacy}] }

// Tool: __audit_log_query
// Args: { token_id?, admin_user_id?, tool_name?, status?, since? (ISO), until? (ISO), limit?, include_payloads?: boolean = false }
// Returns: { count, filters, include_payloads, rows: [...] }

Both tools require a super-admin caller. Since standard content-api tokens have no admin user resolved (see Known limitations), invoking these tools in practice requires:

1. Strapi 5.45+ with features.future.adminTokens: true in config/admin.ts.
2. A token created from a super-admin session (so adminUserOwner populates with that user).

If your setup doesn't meet those conditions, you can still query the tables directly via SQL — the data is captured regardless of whether the introspection tools are usable. Example:

SELECT tool_name, status, duration_ms, admin_email, ip, ts
FROM mcp_op_logs
WHERE ts > datetime('now', '-1 day')
ORDER BY ts DESC
LIMIT 100;

What the audit does NOT do: it does not prevent impersonation — that's structurally impossible in standard Strapi 5.x (see Known limitations). It provides forensic evidence so an incident can be reconstructed after the fact, and it raises the cost of "delete the evidence then deny" since the delete itself is logged.

What this plugin does NOT protect against

• Compromise of the Strapi admin user that creates tokens — out of scope; if the admin is compromised, the attacker can create tokens anyway. The audit will record the creation under that user, which helps post-incident.
• Egress firewall bypass — if your server can reach 169.254.169.254, the plugin blocks but ideally your VPC also blocks. Defense in depth.
• Distributed attacks across multiple instances — rate limit is in-memory per instance. Use a CDN/proxy or Redis backend for cluster-wide limits.

Extensibility: registerTool

Custom tools live in your project's src/index.ts bootstrap:

export default {
  register() {},
  bootstrap({ strapi }) {
    strapi.plugin('strapi-mcp-suite').service('registry').registerTool({
      name: 'feature_article',
      description: 'Marks an article as featured (sets is_featured=true and featured_at=now). Useful when an editor wants to highlight content without opening the admin.',
      inputSchema: {
        type: 'object',
        properties: {
          documentId: { type: 'string' },
          unfeature: { type: 'boolean', default: false },
        },
        required: ['documentId'],
        additionalProperties: false,
      },
      handler: async ({ strapi }, args) => {
        const uid = 'api::article.article';
        const current = await strapi.documents(uid).findOne({ documentId: args.documentId });
        if (!current) throw new Error(`Article ${args.documentId} not found`);

        return strapi.documents(uid).update({
          documentId: args.documentId,
          data: args.unfeature
            ? { is_featured: false, featured_at: null }
            : { is_featured: true, featured_at: new Date().toISOString() },
        });
      },
      testCases: [
        { name: 'rejects unknown', args: { documentId: 'does-not-exist' }, expect: { errorMatches: /not found/ } },
      ],
      tags: ['write'],
    });
  },
};

The registry enforces:

• name is snake_case, 3-64 chars, doesn't collide with a built-in
• description is ≥30 chars (helps the LLM choose when to invoke)
• inputSchema is a valid JSON Schema with additionalProperties: false
• required references only fields present in properties
• handler is an async function
• testCases (optional) follow the expected shape

If validation fails, registerTool throws on boot with a detailed error message.

Use __list_registered_tools

Call this tool from your MCP client to see what's registered and the results of the last self-test run for each custom tool. Useful for debugging.

Testing

Unit tests (Node built-in test runner)

cd src/plugins/strapi-mcp
npm test

145+ tests covering: URL safety (SSRF), schema validator (9 rules), path-lock (concurrency), writer (path traversal defenses), registry (tool definition validation), rate limiting (sliding window, multi-layer), schema derivation, content-ops handlers.

Security smoke test (script against running Strapi)

export STRAPI_MCP_TOKEN=<your-token>
bash src/plugins/strapi-mcp/scripts/smoke-test.sh

Windows:

$env:STRAPI_MCP_TOKEN = "<your-token>"
pwsh src/plugins/strapi-mcp/scripts/security-test.ps1

The security test exercises 18+ regression cases for C1 (path traversal), C3 (SSRF), H1 (GraphQL auth), M1 (find_entries cap, GraphQL query bombs), rate limit, plus manual instructions for C2 (token impersonation) and H3 (backups location).

Troubleshooting

Symptom	Cause	Fix
Tool not appearing in client	Client cached tools/list from a previous session	Fully quit MCP client (system tray → Quit), reopen
Tool "X" no encontrada from new tool	Strapi runs the old plugin dist	Restart Strapi (Ctrl+C + pnpm dev); the plugin doesn't hot-reload
401 Token name email mismatch	Token name contains an email different from adminUserOwner email	Rename token to match the owner's email, or remove email from name
URL_BLOCKED on a legitimate URL	URL caught by SSRF blocklist	Add to UPLOAD_URL_EXTRA_BLOCKED_HOSTS exception list, or switch to allowlist mode
429 Too Many Requests	Rate limit hit	Wait 60s, or raise MCP_RATE_LIMIT_PER_MIN in dev. Restart Strapi to wipe counters
Schema authoring fails with SCHEMA_AUTHORING_DISABLED_IN_PRODUCTION even in dev	NODE_ENV not set	Explicitly set NODE_ENV=development in your .env
Tool "graphql_query" no encontrada	GRAPHQL_ENABLED=false or @strapi/plugin-graphql not installed	Enable + install the plugin
Behind a CDN/proxy, per-IP rate limit triggers immediately	All requests appear to come from the proxy IP	Set proxy: true in config/server.ts
403 [strapi-mcp audit] Delete bloqueado when deleting an API token	Caller is not the original creator and not super-admin	Log in as the creator or as a super-admin. If the token is legacy (created before v0.4.0), only super-admin can delete it.
__audit_token_creators returns AUDIT_REQUIRES_SUPER_ADMIN	Token has no admin user resolved (standard content-api tokens)	Activate features.future.adminTokens: true in config/admin.ts and create the audit-query token from a super-admin session; or query the mcp_token_audits / mcp_op_logs tables directly via SQL.

---

Deep population on reads (v0.5.0)

find_entries and get_entry accept two extra args to materialize a recursive populate tree without you having to hand-craft it:

{
  "uid": "api::page.page",
  "populate_deep": true,
  "populate_depth": 4   // default 4, hard cap 6
}

When populate_deep: true, the plugin walks the live schema and builds a populate object that expands every relation, component, dynamiczone and media field, recursing up to populate_depth levels. Cycles are protected by a visited Set — bidirectional relations don't spin forever.

Trade-offs:

• Queries become larger and slower. Use only when you genuinely need the full context (e.g. rendering a page with all its dynzone sections expanded).
• The pageSize cap of 200 still applies, so worst-case is ~200 entries × the branching at each depth level.
• populate (the explicit object) is ignored when populate_deep: true. The response carries a warning field if you accidentally pass both.

System models (admin::user, plugin::users-permissions.*) are treated as shallow — large trees, rarely useful from an MCP client.

Schema strategies on writes (v0.5.0)

Strapi's Content-Type Builder UI doesn't allow editing a component that nests another component more than 1 level deep. Before v0.5.0, the validator caught proposals exceeding this and returned an error. Now it returns strategies — concrete alternatives the LLM can pick from.

When create_component receives a proposal triggering NESTED_COMPONENT_DEPTH_EXCEEDED, the response shape is:

{
  "success": false,
  "validation": { ... },
  "strategies": [
    { "name": "flat", "available": true, "schema": { ... }, "trade_offs": [...] },
    { "name": "modular", "available": true, "schema": { ... }, "wiring_instructions": "...", "trade_offs": [...] },
    { "name": "dynamiczone", "available": false, "unavailable_reason": "..." }
  ],
  "hint": "Elige una estrategia (flat | modular | dynamiczone) y vuelve a llamar con `strategy: '<nombre>'`."
}

The three strategies:

Strategy	What it does	When it's unavailable
flat	Inlines the nested component's attributes into the parent with a ${attrName}_ prefix. One file, no manual wiring.	Parent attr is repeatable: true, nested component doesn't exist, or prefixed names would collide.
modular	Writes the parent without the nested ref. Returns wiring_instructions with the JSON snippet the user must paste into the parent's schema manually. Maximum reusability.	Always available.
dynamiczone	Converts the offending attribute to a dynamiczone (resets Strapi's depth counter).	Not applicable when the proposal is a component (dynzones only live in content-types).
as-proposed (escape hatch)	Writes the schema EXACTLY as proposed, preserving the depth. The CTB UI rejects opening this component for editing, but Strapi's backend (DB, REST, GraphQL, lifecycle, populate) handles deeper nesting fine.	Always available — for users who know the limitation and prefer JSON-only editing.

To materialize, re-call create_component with strategy: 'flat' | 'modular' | 'dynamiczone' | 'as-proposed'. The plugin applies the strategy, re-validates, and writes.

For a pure dry-run analysis without committing, use propose_schema_strategy — same input, no disk writes, returns the same strategy list.

Batch field additions: add_fields_to_schema

The singular add_field_to_schema triggers a Strapi restart per call (~12s downtime each). When adding 2+ fields to the same schema, use the new add_fields_to_schema (plural) tool: it reads the schema once, merges all fields, validates, and writes once → one restart total.

{
  "uid": "api::page.page",
  "fields": [
    { "field_name": "subtitle", "field": { "type": "string" } },
    { "field_name": "slug",     "field": { "type": "uid", "targetField": "subtitle" } },
    { "field_name": "cover",    "field": { "type": "media" } }
  ]
}

Atomic: if any field collides (within the batch or against existing attributes), the entire operation aborts without writing. No partial states.

Note: Strategy support currently lives in create_component only. create_content_type and add_field_to_schema will get the same fork in a future release.

Full schema mutation in one restart: modify_schema (v0.6.0)

modify_schema is the most powerful schema tool — it combines remove + add + update into one atomic write → a single Strapi restart instead of N:

{
  "uid": "molecules.feature-item",
  "remove": ["legacy_field"],
  "update": [{ "field_name": "count", "field": { "type": "biginteger" } }],
  "add":    [{ "field_name": "slug",  "field": { "type": "uid", "targetField": "title" } }]
}

• remove[] — field names to delete (refuses if a relation in another schema depends on them via inversedBy/mappedBy)
• update[] — replace a field's full definition. The way to change a field's type (e.g. text → string) without orchestrating delete-then-add.
• add[] — new fields (collision-checked)

Applied in order remove → update → add, validated as a whole, written once. Any failure aborts everything — no partial states. Cross-list conflicts (a name in both remove and add, duplicates, etc.) are caught before the filesystem is touched.

Proactive atomization: suggest_reusable_atoms (v0.6.0)

Read-only analysis tool. Walks every component and content-type, counts repeated (fieldName, type) patterns, and flags scalar fields worth promoting to reusable atom components — the classic case of title: string copy-pasted into 8 sections.

{ "scope": "all", "min_occurrences": 3 }

For each strong candidate it returns the used_in list, a starter atom schema (with built-in enrichment for known names — title → atoms.heading with tag/align, icon → atoms.icon with size/color), and an execution_plan of concrete create_component + modify_schema calls you can run after review. It also surfaces depth warnings (when a consumer is itself nested) and a data-migration note. Never writes.

Known limitations

Schema-authoring chains can hang Claude Desktop via mcp-remote

When you call add_field_to_schema (or any schema-authoring tool), Strapi restarts in dev mode and the MCP endpoint is unreachable for ~10-15s. Two compounding issues make this fragile when chaining multiple operations from Claude Desktop:

1. The LLM frequently ignores restart_info.estimated_downtime_seconds. Observed in live testing: Claude received estimated_downtime_seconds: 12 and called __health just 2 seconds later, hitting Strapi mid-restart. The plugin can only emit hints in the tool response — the protocol has no mechanism to block the next call for N seconds.
2. The mcp-remote bridge gives up after 2 reconnection attempts. Claude Desktop uses mcp-remote as an stdio↔HTTP bridge. When the endpoint returns ECONNREFUSED during the restart window, mcp-remote tries twice and then throws Maximum reconnection attempts (2) exceeded. Even when Strapi comes back, the session stays dead until Claude Desktop is fully restarted.

Workarounds:

• Prefer batch operations. Use add_fields_to_schema (plural) to apply N fields in one restart instead of N restarts. Same logic applies to create_content_type with all attributes defined up front. Each restart is one chance to lose the session — minimize the count.
• Restart Claude Desktop completely (system tray → Quit, NOT just close the window) if a chain fails mid-way. Reopening clears the dead bridge.
• For projects with slow boot (TypeScript types + many plugins + WSL/VMs), restart_info may underestimate. After a schema operation, wait ~25s manually before any next MCP interaction.
• Consider Claude Code instead of Claude Desktop for heavy schema-authoring sessions. Claude Code talks to the MCP server over HTTP directly (no stdio bridge) and handles ECONNREFUSED more gracefully.

This is a Claude Desktop + mcp-remote compatibility issue, not a plugin bug — the endpoint behaves identically to any other HTTP service during restart. The audit log shows the operation succeeded server-side even when the client sees a hung session.

Anti-impersonation via adminUserOwner is not implemented

An earlier security audit identified a scenario: if a user with permission to create API tokens names their token "[email protected] - mcp", all writes via that token would be attributed to the CEO via the email-in-token-name convention. The initial fix in 0.3.0 tried to mitigate this by verifying the token's adminUserOwner field against the email in the name.

Investigation in 0.3.1 revealed the mitigation is not feasible in standard Strapi 5.x. The adminUserOwner field is only populated for tokens of kind='admin' (a feature gated behind features.future.adminTokens: true in config/admin.ts — experimental, not enabled by default). Standard content-api tokens (the ones created from Settings → API Tokens) have adminUserOwner forced to null by Strapi's admin service (see source).

The check was removed in 0.3.1 because keeping it would generate false confidence — for the vast majority of users, the policy would degrade to "no attribution" anyway without rejecting impostor tokens.

Workarounds if you need strict attribution per user:

1. Activate the experimental flag in config/admin.ts:

   features: {
     future: { adminTokens: true }
   }
   

   Then create tokens via the /admin/admin-tokens REST endpoint (not the UI). Those tokens have adminUserOwner populated and the plugin attributes correctly.

2. Enforce token naming convention via process: have a policy where developers MUST include their own email in tokens they create. Audit token names periodically against admin user roster. This is process-based, not technical.

3. Wait for Strapi to stabilize the feature: when adminTokens graduates from "future" to a stable API, the plugin can rely on it for all installations.

Other known limitations

• Rate limit is in-memory per instance. Multi-instance setups behind a load balancer don't share counters. Use a CDN/proxy rate limit or Redis backend (planned for future release).
• Schema authoring requires Strapi restart to take effect. The plugin tells the LLM to wait via restart_info, but cannot eliminate the restart itself (Strapi loads schemas in boot).
• GraphQL tools depend on @strapi/plugin-graphql being installed and GRAPHQL_ENABLED=true. If absent, tools are not exposed.

Roadmap

• npm publish: strapi-plugin-mcp-suite
• Forensic audit trail (token lifecycle + operations) — v0.4.0
• Deep populate on reads + progressive schema strategies on writes — v0.5.0
• Strapi marketplace approval
• Redis backend for rate limiting (multi-instance support)
• Admin UI panel for browsing the audit log
• Token rotation hooks
• More i18n-specific tools (clone_entry_to_locale, list_locales)
• delete_content_type with multi-step confirmation
• Re-implement anti-impersonation when Strapi stabilizes adminTokens future flag
