AnythingMCP: self-hosted MCP gateway

English · Deutsch · 简体中文 · 日本語

AnythingMCP is an open-source, self-hosted MCP gateway that turns any REST/OpenAPI, SOAP, GraphQL, OData or SQL system into MCP tools for Claude, ChatGPT and Copilot, without writing an MCP server.
It ships 325 ready connectors, among them SAP, Etsy, weclapp and Amazon Seller, and 17 of them need no API key.

Run it yourself

Requires Docker 24+ and openssl; on macOS, start Docker Desktop first. No clone needed:

mkdir anythingmcp && cd anythingmcp
curl -fsSLo docker-compose.yml \
  https://raw.githubusercontent.com/HelpCode-ai/anythingmcp/main/docker-compose.quickstart.yml
printf 'JWT_SECRET=%s\nENCRYPTION_KEY=%s\n' "$(openssl rand -hex 32)" "$(openssl rand -hex 32)" > .env
docker compose up -d

Open http://localhost:3000 and register: the first account becomes admin. Your MCP endpoint is http://localhost:4000/mcp, the API docs are at http://localhost:4000/api/docs.

Keep the generated .env. ENCRYPTION_KEY decrypts the credentials you store. Lose it and every connector has to be re-credentialed.

On amd64 the image pulls in about 30 s and the API is healthy 24 s later. The image is amd64 only for now; the compose file pins the platform, so it also runs on Apple Silicon under emulation.

The quickstart binds to 127.0.0.1 on purpose, because nothing in front of it terminates TLS. For an instance other people or a cloud AI client can reach, clone the repo and run ./setup.sh: it asks for a domain, gets certificates through Caddy, generates the secrets and sets the MCP auth mode. See the Deployment Guide.

Other ways to run it: managed cloud, Railway, DigitalOcean

AnythingMCP Cloud is the same AGPL code, operated by us in Frankfurt, Germany, with a 7-day free trial. Start there to try it on your own APIs, and move it in-house when you want the credentials to stop travelling; the connectors are the same either way. DPA/AVV on request via [email protected]. SSO and SCIM are self-hosted only.

How it works

1. Add a connector. Install an adapter from the catalog (a ready JSON definition for SAP, Odoo, DHL and the rest), or point AnythingMCP at your own OpenAPI spec, WSDL, GraphQL endpoint, Postman collection or database. Once configured in your workspace it is a connector, and each of its operations is an MCP tool.
2. Decide what the model sees. Rename and describe the tools in the visual editor, drop the fields that must not leave your network, and choose which roles may call which tools.
3. Hand one URL to your AI client. An MCP server is the endpoint you add to Claude, ChatGPT, Copilot, Gemini or Cursor. It exposes the connectors you assign to it, and nothing else.

Connect any API, SOAP service or database

Most companies have no MCP servers yet. They have a REST API, an ERP, a SOAP service from 2009 and a database. Each of them becomes a set of MCP tools:

Source	What you get	Docs
OpenAPI / Swagger (REST)	Import a spec by URL or paste it; every operation becomes a tool with parameters, auth and endpoint mapping filled in	REST · guide · demo: openapi-to-mcp
Postman collection, cURL	Folders, auth, body modes and {{variables}} carry over; every request becomes a tool	Postman import
SOAP / WSDL	Each operation becomes a tool; envelopes, parameter order and WCF services are handled for you	SOAP · guide · demo: soap-to-mcp
GraphQL	Introspection turns queries and mutations into tools, or you define the operations yourself	GraphQL · guide
OData (SAP Gateway included)	Reads each service's $metadata, so the model sees entity sets, keys and SAP's business labels; V2 and V4	OData · guide
SQL and MongoDB	PostgreSQL, MySQL, MariaDB, SQL Server, Oracle, SAP HANA, SQLite and MongoDB: schema, example and query tools, read-only by default	Database · SAP HANA · guide · demo: sql-to-mcp
Another MCP server	Discover its tools and serve them next to your own, behind the same auth and audit	MCP bridge

Tools register at runtime, without a restart. Per-connector {{VAR}} values are interpolated on the server and never shown to the AI.

An adapter is a single JSON file. That is why the catalog is this size, and why adding one is a reasonable first contribution. Missing yours? Request it (we prioritise by 👍) or build it. Your ERP isn't listed, or it's a custom build? Connect its REST API, its SOAP services or its SQL database directly, read-only.

Security and governance

Everything runs on your infrastructure, so you decide what leaves it. OAuth2, RBAC, SSO and SCIM are in the self-hosted build, not held back for a paid tier.

• Response mapping. Each tool declares exactly which fields reach the model: drop a customer's IBAN or an employee's salary, or name the fields to keep. The editor shows the before/after on a real response; a shipped adapter goes from 12,172 B to 1,072 B (−91%), so you also stop paying for those fields in the context window. A broken mapping returns the raw response by default; set "fallbackToRaw": false on tools whose fields must never travel, and the call fails instead.
• Read-only where it matters. Every tool carries MCP annotations (readOnlyHint, destructiveHint), derived from the operation and overridable per tool. Role-based tool whitelisting lets you publish an MCP server that can only read, which is how most people should start with an ERP. Database query tools run a single SELECT and block writes and stacked statements.
• Every auth scheme you will meet. OAuth2 (PKCE and Client Credentials), Bearer, API key, Basic, HMAC request signing, LOGIN_TOKEN and OAuth 1.0a. Credentials are encrypted at rest with AES-256-GCM.
• Audit log. Every tool call is recorded with input, output, duration and status in your own database, including the full upstream response the model never saw.
• SSO and SCIM. Entra ID, Google, Okta, Auth0 or any OIDC provider. Roles sync from your directory groups on every sign-in; disable someone in the directory and their workspace access and MCP API keys go with it.

{
  "transform": {
    "mode": "select",
    "fallbackToRaw": false,
    "exclude": ["customer.iban", "customer.taxId"],
    "select": { "order": "$.id", "total": "$.amounts.gross", "status": "$.state" }
  }
}

Use it from Claude, ChatGPT, Copilot and Gemini

The same MCP server works in every client that speaks MCP, so you build a connector once:

• Claude. Add the server URL as a custom connector under Customize → Connectors; it then works in Claude.ai, Claude Desktop and Claude Code. OAuth 2.0 is supported out of the box. On AnythingMCP Cloud you can also add it in one click from the Claude Directory. Claude setup
• ChatGPT. Apps in ChatGPT are built on MCP. Add the server in ChatGPT's settings, or use it as the tool layer of an Apps SDK app. ChatGPT setup
• Meta Muse. In Muse, open Settings → Connectors → Add custom connector, paste the server URL and sign in to AnythingMCP. Muse setup
• Copilot, Gemini, Cursor and other MCP clients: client setup guides.

Knowledge Graph and AI skills

Forwarding calls leaves the hard part to the agent: knowing which tool to call next, and what your business means by "open order". AnythingMCP learns both and hands them back as context, not as extra tool calls.

• Knowledge Graph. A per-workspace map of entities (customers, orders, products) and how they relate across connectors, built from tool definitions and real calls, and editable by hand. It stores field names and relationships, never values. Each server exposes it through a kg_how_to_obtain tool, so the agent can ask how to get from a Shopware order to a DHL tracking number.
• AI skills. Recurring usage turned into small rules ("today's revenue includes order statuses 2, 3 and 4") that you apply, edit or dismiss, and that are composed into the server's instructions.

The AI passes are off by default and use your own OpenAI, OpenRouter or Anthropic key; the graph, the editor and the MCP tool work without one. Knowledge Graph guide

Where it fits

Most MCP gateways federate and secure MCP servers you already have. AnythingMCP starts one step earlier: it creates the MCP servers from the APIs, ERPs and databases you already run, then serves, scopes and audits them behind one endpoint. If your tools are already MCP servers and all you need is federation, a pure gateway may be enough. Side-by-side comparisons: anythingmcp.com/vs.

FAQ

What is an MCP gateway?

A single MCP endpoint in front of many tools, which handles authentication, access control and audit for all of them. AI clients such as Claude and ChatGPT connect to the gateway instead of to each system. AnythingMCP is a gateway that also generates the tools, from APIs and databases that have no MCP server of their own.

How do I connect my ERP (SAP, Odoo, Xentral…) to Claude or ChatGPT?

Install the ERP's adapter from the catalog, enter the API credentials, and add your MCP server URL to Claude as a custom connector or to ChatGPT as an app. If your ERP has no adapter, connect its REST or SOAP API or its SQL database directly. Start with a role that can only read.

How do I turn an OpenAPI spec into an MCP server?

Create a REST connector and import the spec by URL or by pasting it. Every operation becomes an MCP tool on your server's /mcp endpoint, with no code. How it works

Can I connect a SOAP/WSDL service to Claude?

Yes. AnythingMCP parses the WSDL, turns each operation into a tool and builds the SOAP envelope on every call, WCF services included. It authenticates with HTTP Basic, Bearer, an API-key header or a WS-Security UsernameToken; signed WS-Security messages are not supported yet. SOAP connector docs

Can Claude query my SQL Server, Oracle or PostgreSQL database safely?

Query tools are read-only by default. On top of that, use a database user with SELECT rights only, prefer static queries where the model supplies just the parameters, and whitelist the tools per role. Response mapping drops the columns that must not reach the model, and every query lands in your audit log.

How do I connect Shopware, WooCommerce or Amazon Seller Central to Claude?

Install the e-commerce adapter for your shop or marketplace and authorise it. WooCommerce comes with 49 tools, Amazon Seller Central uses the official Selling Partner API, and the Shopware 6 adapter reads the storefront catalog through the Store API.
