API 200 is an open source API gateway for managing third-party APIs, with endpoint import, caching, retries, mocks and monitoring. It is offered as a managed cloud service and as a self-hosted setup, and includes MCP support.

Key features

01Import endpoints from OpenAPI and Postman
02Response caching and automatic retries
03Mock and fallback responses
04Schema change watching
05Automatic incident detection and endpoint monitoring
06Self-hosted deployment option

Use cases

01Accessing multiple third-party APIs through one gateway
02Configuring caching, retries and fallbacks for external APIs
03Monitoring endpoint statistics and receiving API incident alerts

MCP support

The project provides an MCP server that can be added as a custom tool in Claude Desktop or other clients, letting them reach APIs integrated through API 200.

Configuration

Local server config is the same for every client. Copy it into your client’s MCP config file.

  "mcpServers": {
    "api200": {
      "command": "npx",

Quickstart

Get started immediately with our managed version of API 200. Users can go to our cloud platform and start integrating API endpoints instantly without any setup or infrastructure management. Visit API200.co to begin.

MCP

To configure the API200 MCP server with Claude Desktop (or any other client):

Open Claude Desktop settings
Navigate to Developer settings
Add a new custom tool with the following configuration (can be found on the Credentials tab):

{
  "mcpServers": {
    "api200": {
      "command": "npx",
      "args": [
        "api200-mcp@latest"
      ],
      "env": {
        "USER_KEY": "your-api-key-here"
      }
    }
  }
}

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
