OpenAPI MCP Server

MCP server that turns any OpenAPI/Swagger spec into queryable tools for your LLM. Search endpoints, get endpoint details, and explore schemas from your API documentation.

Setup for Claude Code

Add to your .mcp.json, .claude.json or claude_desktop_config.json.

{
  "mcpServers": {
    "my-api": {
      "command": "uvx",
      "args": [
        "--from",
        "git+https://github.com/puelpan/openapi-spec-mcp.git@main",
        "openapi-spec-mcp",
        "/path/to/your/openapi.yaml"
