Open Archives MCP Server

Production-grade hybrid MCP + HTTP + SSE server generated from the Open Archives OpenAPI specification. Covers genealogical records (births, deaths, marriages, censuses), archive statistics, historical weather, and full-text page transcriptions of historical documents. It is available as a remote MCP endpoint.

Teams that want a hosted search endpoint instead of running a local process. The project is written in TypeScript.
