build-mcp

Converts API specifications into production-ready MCP servers from OpenAPI, Swagger, Postman, HAR, and GraphQL formats.

build-mcp generates MCP servers from API specifications in a single command. Each generated server exposes exactly two tools regardless of API size: a semantic search tool for discovering endpoints via vector embeddings, and an API call tool that validates parameters and executes requests. This approach avoids context window bloat from large APIs. Supports OpenAPI 3.x, Swagger 2.x, Postman Collections, HAR files, and GraphQL schemas, with local SQLite-backed embeddings.
