Schematic

An MCP server that connects AI assistants to Schematic -- the platform for managing billing, plans, features, and entitlements.

Use this server to let Claude, Cursor, or any MCP-compatible client look up companies, manage plan entitlements, set overrides, create features, and more -- all through natural language.

Quick Start

Prerequisites

1. Get your Schematic secret API key: Sign up for a Schematic account and get your secret API key from the Schematic dashboard. Note: use your secret API key, not the publishable key.

Installation

Option 1: Using Claude CLI (Recommended)

1. Install the package from npm:

   npm i @schematichq/schematic-mcp
   

2. Add the MCP server to Claude:

   claude mcp add --transport stdio --scope project schematic --env SCHEMATIC_API_KEY=your-secret-api-key-here -- npx @schematichq/schematic-mcp
   

   Replace your-secret-api-key-here with your actual Schematic API key.

Option 2: Manual Configuration

Claude Desktop / Claude Code

Add to your Claude config (~/Library/Application Support/Claude/claude_desktop_config.json on macOS):

{
  "mcpServers": {
    "schematic": {
      "command": "npx",
      "args": ["-y", "@schematichq/schematic-mcp"],
      "env": {
        "SCHEMATIC_API_KEY": "your-secret-api-key-here"
      }
    }
  }
}

Cursor

Add to your Cursor MCP config (Settings > MCP Servers, or edit the file directly):

• macOS: ~/.cursor/mcp.json
• Linux: ~/.cursor/mcp.json
• Windows: %USERPROFILE%\.cursor\mcp.json

{
  "mcpServers": {
    "schematic": {
      "command": "npx",
      "args": ["-y", "@schematichq/schematic-mcp"],
      "env": {
        "SCHEMATIC_API_KEY": "your-secret-api-key-here"
      }
    }
  }
}

After adding the config, restart Cursor for the server to be picked up.

Configuration

The server needs a Schematic secret API key (not the publishable key). It checks two sources in order:

1. Environment variable (recommended): SCHEMATIC_API_KEY
2. Config file (fallback): ~/.schematic-mcp/config.json

{
  "apiKey": "your-secret-api-key-here"
}

You can find your secret API key in the Schematic dashboard.

Custom API base URL (optional)

By default the server targets the production Schematic API. To point it at a local or non-production API, set SCHEMATIC_API_URL:

{
  "command": "npx",
  "args": ["@schematichq/schematic-mcp"],
  "env": {
    "SCHEMATIC_API_KEY": "your-secret-api-key-here",
    "SCHEMATIC_API_URL": "http://localhost:8080"
  }
}

When unset, the SDK's production default is used.

Tools

Company Lookup

Tool	Description
get_company	Look up a company by ID, name, Stripe customer ID, or custom key. Returns details, plan, trial status, and links.
create_company	Create (upsert) a company identified by a key (keyName/keyValue), with an optional name and traits. Updates the company if the key already exists.
get_company_plan	Get the plan a company is currently on.
get_company_trial_info	Check if a company is on a trial and when it ends.
count_companies_on_plan	Count how many companies are on a specific plan.
link_stripe_to_schematic	Find the Schematic company for a Stripe customer ID, or vice versa.

Company Overrides

Tool	Description
list_company_overrides	List overrides by company or by feature.
set_company_override	Set or update an override for a company on a specific feature. Supports boolean (on/off), numeric, and unlimited values.
remove_company_override	Remove an override so the company falls back to plan entitlements.

Plan Management

Tool	Description
list_plans	List all plans.
create_plan	Create a new plan.
add_entitlements_to_plan	Add feature entitlements to a plan. Auto-detects feature type and sets appropriate value types.

Feature Management

Tool	Description
list_features	List all features.
create_feature	Create a new feature flag. Supports boolean (on/off), event-based (metered), and trait-based types. Automatically creates an associated flag.

Flag Management

Tool	Description
list_flags	List all flags with a targeting summary — for each flag: key, default value, linked feature, and whether it resolves to always-on, always-off, or targeted. Useful for auditing always-on flags (redundant to check in code) or unused flags (candidates for deletion).
get_flag	Get full targeting detail for one flag by key: default value, every rule (type, value, priority, condition count), last-checked time, and the always-on / always-off / targeted determination.

Example Prompts

Once configured, try asking your AI assistant:

• "What plan is Acme Corp on?"
• "List all my plans and their features"
• "Create a boolean feature called 'Advanced Analytics'"
• "Set an override for Acme Corp to have unlimited API calls"
• "How many companies are on the Pro plan?"
• "Find the Schematic company linked to Stripe customer cus_abc123"
• "List all flags and tell me which ones are always-on"
• "Show me the targeting rules for the billing.credits flag"
