AnythingMCP

AnythingMCP is an open-source, self-hosted gateway for the Model Context Protocol. It converts existing business systems, whether REST or OpenAPI, SOAP, GraphQL, OData or SQL, into MCP tools that AI assistants such as Claude, ChatGPT and Copilot can call, so teams do not need to write a custom MCP server for each system.

It ships with 265 ready connectors, including SAP, Etsy, weclapp and Amazon Seller, of which 21 need no API key, and topics also mention ERP and e-commerce platforms. The quick start needs Docker and openssl: the first account you register becomes the admin, the MCP endpoint is served at /mcp and API docs at /api/docs. A generated encryption key protects stored credentials and must be kept safe. For instances reachable by others, a setup script configures a domain, TLS through Caddy and the MCP authentication mode.

The code is written in TypeScript under AGPL-3.0. A managed AnythingMCP Cloud runs the same code in Frankfurt, Germany with a seven-day free trial, and Railway and DigitalOcean deployments are documented, so you can start hosted and move in-house later.
