Open Archieven

The Open Archieven server is a schema-aware, auto-generating server designed to expose the Open Archives genealogical search engine's API through a variety of transports. It automatically converts the OpenAPI specification into 17 callable tools, complete with schema-perfect validation for parameters. Developers can interact with the API via MCP Remote (JSON-RPC over StreamableHTTP), a standard HTTP JSON API, SSE streaming with auto-pagination, or chunked HTTP streaming. The server also includes robust features such as optional Redis caching for improved performance, a token-bucket rate limiter to manage upstream API calls, and built-in health checks for operational monitoring.
