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.

🏭 Built for production — AnythingMCP was born from real-world needs at a German industrial group connecting 15+ legacy systems (ERP, CRM, IoT) to 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
• Track parcels with AI — built-in MCP servers for DHL, DPD, GLS, Shipcloud and Sendcloud
• Automate B2B compliance — pre-flight every invoice with VIES VAT validation and Handelsregister lookups
• Let AI agents query your production database safely — read-only database connectors with audit logging
• Bridge legacy SOAP services to modern AI workflows — automatic WSDL parsing, no code changes
• Aggregate multiple MCP servers behind one gateway — MCP-to-MCP bridge for unified tool access
• Import your Postman collection and get MCP tools instantly — zero-config API onboarding

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 SEO-optimized guide on anythingmcp.com (English, German, Italian).

Logistics & Shipping

ERP, Accounting & Invoicing

E-commerce & Catalog

HR & Field Service

Government & Public Data

Banking, Payments & Remote

Construction & Mapping

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.

Quick Start

git clone https://github.com/HelpCode-ai/anythingmcp.git
cd anythingmcp
./setup.sh                 # Interactive setup — generates .env, starts Docker

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:

Connector Guides

Each connector type has dedicated documentation with setup instructions, examples, and best practices:

                          PostgreSQL  │  Redis (optional)

How it works:

1. 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
2. Import or Define Tools — Auto-import from OpenAPI/Postman/WSDL/GraphQL or define manually. Pre-built adapters skip this step.
3. Connect AI Clients — Point your MCP client to http://your-server:4000/mcp
4. 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.

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.
