🏭 Origin story — AnythingMCP started inside a German industrial group that needed AI agents to talk to 15+ legacy systems (ERP, CRM, custom SOAP, on-prem Postgres). Writing one MCP server per system would have taken weeks each; we extracted the common gateway after the third rewrite and have been running it in production for ~6 months.
Self-hosting instead? Run ./setup.sh for the interactive Docker setup. See Quick Start below.
What is AnythingMCP?
AnythingMCP is a self-hosted, source-available MCP server and API gateway that turns your existing APIs into Model Context Protocol (MCP) tools. Connect any API — REST, SOAP, GraphQL, databases, or other MCP servers — and expose them to AI clients like Claude, ChatGPT, Google Gemini, GitHub Copilot, Cursor, and any other MCP-compatible client.
No SDK. No code changes. Just point, configure, and connect.
Built-in adapters ship with the catalog so you get an instant MCP server for popular SaaS and public APIs — DHL, DPD, GLS, Shipcloud, Sendcloud, Deutsche Bahn, DATEV, Weclapp, Xentral, Shopware 6, Personio, Handelsregister, VIES VAT, OpenPLZ, HERE Geocoding, Oxomi and more (full list below).
Looking for an MCP gateway? AnythingMCP acts as a universal MCP proxy and API-to-MCP bridge — the missing middleware between your APIs and AI agents.
Get Started in 60 Seconds
git clone https://github.com/HelpCode-ai/anythingmcp.git
cd anythingmcp && ./setup.sh
# Open http://localhost:3000 — done!
See the full Quick Start below for detailed configuration options.
Use Cases
Talk to your ERP from Claude Desktop — connect SAP, Oracle, Weclapp, Xentral, DATEV or any REST/SOAP ERP and query it conversationally
Database Auto-Tools — Schema introspection + dynamic query execution out of the box
Environment Variables — Per-connector {{VAR}} interpolation, hidden from AI
Full Auth — OAuth2 (PKCE + Client Credentials), Bearer Token, API Key, Basic Auth, Query-Param Auth, WS-Security, Certificates
Audit Logging — Every tool invocation logged with input, output, duration, status
Roles & Access Control — Tool-level whitelisting per custom role
Per-User MCP API Keys — Individual keys with usage tracking
Docker Ready — docker compose up and you're running
Pre-configured MCP Connectors
AnythingMCP ships with 29 ready-to-use MCP server adapters — provide your API credentials at import time and the tools become available to your AI client immediately. Each adapter has its own setup guide on anythingmcp.com (English, German, Italian).
📍 Heads-up on the catalog: the starting set leans heavily DACH (Germany / Austria / Switzerland) because that's where we built this in production first. US/UK/APAC SaaS adapters are very welcome as community PRs — there's a good first issue walking you through adding one in ~30 minutes (it's a single JSON file).

Want to add your own? Create a JSON adapter file in packages/backend/src/adapters/ (organized by region, e.g. de/), register it in catalog.ts, and it becomes available to all users. The new catalog.spec.ts parametrized test validates every adapter at build time. See the existing adapters and the Tool Definition Format for the expected schema.

The setup script configures everything interactively: deployment mode, domain/SSL, auth, email, Redis, and more. All secrets are auto-generated. First user to register becomes Admin.
What setup.sh handles:
Domain and HTTPS — for production domains, enables Caddy reverse proxy with automatic Let's Encrypt SSL
Secrets — generates JWT, encryption keys, and database passwords
MCP authentication mode — OAuth 2.0, API Key, or both
Optional SMTP and Redis configuration
Prefer manual setup? Copy .env.example to .env, edit the values, and run docker compose up -d. See the Deployment Guide for details.

Next step: Create a connector, import your API spec, and connect your AI client. See the Connector Guides below.
Connect Your AI Client to the MCP Server
AnythingMCP works with any MCP-compatible client. Follow the guide for your AI tool:
Create a Connector — Point to your API (REST base URL, WSDL endpoint, GraphQL URL, database connection string) or pick a pre-built adapter from the catalog
Import or Define Tools — Auto-import from OpenAPI/Postman/WSDL/GraphQL or define manually. Pre-built adapters skip this step.
Connect AI Clients — Point your MCP client to http://your-server:4000/mcp
AI calls tools — AnythingMCP translates MCP tool calls into actual API requests and returns results
FAQ
What is an MCP server?
An MCP server exposes tools to an AI agent over the Model Context Protocol — an open standard from Anthropic. Once connected, the AI can call those tools to read data, run queries, or perform actions on your behalf. AnythingMCP is a self-hosted MCP server that wraps your existing APIs so you don't have to write one from scratch.
How is AnythingMCP different from writing my own MCP server?
You don't write code. AnythingMCP imports your OpenAPI/Postman/WSDL spec (or you point it at a database) and generates the MCP tools automatically. You also get auth, audit logging, RBAC, and a visual editor on top — features that would take weeks to build per service.
Can I use AnythingMCP with Claude / ChatGPT / Gemini / Copilot / Cursor?
Yes. Any client that speaks MCP works. See the Connect Your AI Client table for direct setup guides.
Why source-available and not "open source"?
We use the Business Source License 1.1 (BSL-1.1), the same model as Sentry, MariaDB, CockroachDB and HashiCorp Terraform. The source is fully public, you can read, fork, modify and self-host — but you can't resell it as a managed SaaS without a commercial license. On 2030-03-04 the license automatically converts to Apache 2.0, so the code is guaranteed to become OSI-approved open-source. We chose this over MIT/Apache up-front to keep building AnythingMCP sustainably while avoiding the AWS-strip-mining trap. See the License FAQ for plain-language details.
Is AnythingMCP free?
Yes, for everyone except SaaS resellers. Free for internal company use, personal use, development, testing, evaluation and academic use. The only restriction is offering it as a hosted commercial service to third parties without a commercial license — and even that restriction lifts on 2030-03-04 when BSL converts to Apache 2.0.
Can I self-host AnythingMCP?
Yes — it ships as a Docker image and runs on your own infrastructure. Run ./setup.sh or use the Railway and DigitalOcean Marketplace one-click installs. There's also a managed Cloud version if you'd rather not run it yourself.
Is there an MCP server for [DHL / DPD / GLS / DATEV / Weclapp / Personio / Handelsregister / etc.]?
Yes — see the Pre-configured MCP Connectors table above. Each adapter has its own setup guide on anythingmcp.com. If your service isn't there yet, you can add it in 10 minutes by copying an existing JSON adapter and adapting the endpoints.
What about SOAP and WSDL?
Built-in. AnythingMCP automatically parses WSDL documents and generates one MCP tool per SOAP operation. Useful for legacy enterprise APIs (SAP, Oracle, .NET WCF, banking middleware) that no AI client speaks natively.
Is MCP dead now that agents use CLI tools?
No — but the question conflates two different problems. CLI is the right call when the model already knows the tool from training (git, docker, kubectl, aws, gh), the agent is acting for the builder, and a CLI actually exists. MCP wins when you need per-user auth, scoped permissions, audit logs, multi-tenant isolation, typed contracts, or SaaS integrations without a CLI (Salesforce, Workday, Notion, Linear, internal tools).
The mature pattern in 2026 is hybrid: CLI for local/dev/popular tools, MCP for SaaS / multi-tenant / compliance-bound integrations. AnythingMCP covers the MCP side — you keep using git and docker directly, the gateway handles everything else with proper auth and audit. Full breakdown with a decision matrix is on anythingmcp.com/vs/cli.
Can the AI access my production database directly?
Yes, with safety. AnythingMCP supports PostgreSQL, MySQL, MariaDB, MSSQL, Oracle, MongoDB and SQLite. Each tool is whitelisted, every invocation is audit-logged, and you can scope a connector to read-only credentials. See the Database Connector Guide.
How is auth handled?
OAuth2 (PKCE + Client Credentials), Bearer Token, API Key, Basic Auth, query-parameter auth, WS-Security and TLS client certificates are all supported. Credentials are stored AES-256-GCM encrypted at rest. Per-user MCP API keys are issued on top so each AI client gets its own key with usage tracking.
AnythingMCP is source-available under the Business Source License 1.1 (BSL-1.1). This is not an OSI-approved open-source license — see the License FAQ for a plain-language explanation.
Free for: internal use, personal use, development, testing, evaluation, academic use
Not permitted: offering as a commercial hosted service (SaaS) without a separate license
Change Date: 2030-03-04 — on this date the license automatically converts to Apache 2.0
Transparency note: AnythingMCP makes optional network calls to anythingmcp.com for license verification and email delivery when SMTP is not configured. No API credentials or tool invocation data is ever sent. See External Services for full details.
