anythingmcp

AnythingMCP is a self-hosted, open-source MCP gateway and MCP server that turns the systems you already run into Model Context Protocol tools — REST and SOAP APIs, GraphQL, SQL & NoSQL databases, and even other MCP servers. Import a spec or point it at a database, and expose it as a custom connector to Claude, ChatGPT, Gemini, Copilot, Cursor and any MCP-compatible client. No SDK, no code changes — point, configure, connect.

It ships with 175+ ready-to-use adapters — including Deutsche Bahn, weclapp ERP, Etsy, Shopware, DHL and Sendcloud — so the most common integrations work in one click, while the visual editor and import tools (OpenAPI/Swagger, Postman, cURL, WSDL, GraphQL) let you wrap any other API or database in minutes.

Get started in 60 seconds

Requires Docker 24+, bash, openssl. On macOS, start Docker Desktop first.

git clone https://github.com/HelpCode-ai/anythingmcp.git
cd anythingmcp && ./setup.sh
# When setup finishes, open http://localhost:3000 and register
# the first user — they automatically become the admin.

The interactive setup handles everything: deployment mode, domain & HTTPS (automatic Let's Encrypt via Caddy), secrets, MCP auth mode, optional SMTP/Redis.

⚠️ Register immediately after setup. The first account to register becomes Admin. If your instance is reachable from the internet during setup, configure firewall rules or bind the UI to 127.0.0.1 until you've created the admin account.

Or one-click deploy:

Prefer manual setup? Copy .env.example to .env and run docker compose up -d — see the Deployment Guide.

Key features

• 5 connector types — REST, SOAP, GraphQL, Database (PostgreSQL, MySQL, MariaDB, MSSQL, Oracle, MongoDB, SQLite), MCP-to-MCP bridge

• 6 import formats — OpenAPI/Swagger, Postman, cURL, WSDL, GraphQL introspection, custom JSON

• 175+ pre-built adapters — logistics, ERP, HR, e-commerce, payments, public data — see catalog

• Visual tool editor — map parameters to path, query, body, headers; rename and describe tools for the AI

• Dynamic MCP server — tools registered at runtime, no restart

• Full auth — OAuth2 (PKCE + Client Credentials), Bearer, API Key, Basic, WS-Security, client certificates, LOGIN_TOKEN and OAuth 1.0a handshakes

• Audit logging — every tool call logged with input, output, duration, status

• Roles & access control — tool-level whitelisting per custom role, per-user MCP API keys

• Environment variables — per-connector {{VAR}} interpolation, hidden from the AI

• Docker ready — docker compose up and you're running

Build custom Claude connectors — no code

Claude supports custom connectors: remote MCP servers you add once in Settings → Connectors, and that work across Claude.ai, Claude Desktop and Claude Code. AnythingMCP creates that connector from any API you already have — without writing an MCP server:

1. Import your API spec (OpenAPI/Swagger, Postman, cURL, WSDL, GraphQL introspection) or pick a pre-built adapter

2. Adjust tool names, descriptions and parameters in the visual editor — what the AI sees is up to you

3. Add the gateway URL to Claude as a custom connector (OAuth 2.0 supported out of the box)

Your credentials stay on your infrastructure (AES-256-GCM at rest), every tool call lands in the audit log, and role-based access controls which users see which tools. Step-by-step guide →

Turn your API into a ChatGPT app

Apps in ChatGPT — what OpenAI renamed connectors to in December 2025 — are built on MCP, and AnythingMCP gives you that MCP backend without writing one. Point it at your REST, SOAP, GraphQL or database endpoint and you get a ChatGPT-ready connector: add it in ChatGPT's settings (or use it as the tool layer of an Apps SDK app) and ChatGPT can read and act on your business data.

The same connector works simultaneously in Claude, ChatGPT, Gemini, Copilot and Cursor — build once, connect everywhere. ChatGPT setup guide →

Why AnythingMCP

AI clients speak MCP, but your systems speak REST, SOAP, GraphQL and SQL. Writing and maintaining a bespoke MCP server per system — with auth, audit and access control — takes weeks each. AnythingMCP is the no-code layer in between:

Typical use cases — search train schedules and live delays with Deutsche Bahn · talk to your ERP from Claude (weclapp, Xentral) · track parcels with AI (DHL, GLS) · validate invoices (VIES VAT, Handelsregister) · let agents query production databases safely · bridge legacy SOAP to modern AI · import a Postman collection and get MCP tools instantly.

Pre-configured MCP connectors

AnythingMCP ships with 175+ ready-to-use adapters — provide your API credentials at import time and the tools become available immediately. Every adapter has a setup guide on anythingmcp.com/guides (English, German, Italian).

Community & support

• 💬 Questions & discussions — GitHub Discussions — vote on the next adapter, share what you've built

• 🐛 Bugs / 💡 features — Issues · 🆘 SUPPORT.md

• 🏢 Built by helpcode.ai in Freiburg, Germany — AnythingMCP was extracted from a production system connecting AI agents to 15+ legacy systems (ERP, CRM, SOAP, on-prem databases) in a German industrial group, and open-sourced because the catalog grows faster as a community. AI-assisted development, human-reviewed: see AUTHORS.md.
