A side-by-side look at the Sifter and Fetch MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
SifterSearch & Data Extraction · Local subprocess (stdio)Structure any document, query it like a database. Open-source extraction engine that turns any document into typed, schema-defined records, queryable in natural language from Claude, ChatGPT, Gemini, or any MCP client.55GoodAuth: api key requiredVerdict: choose Sifter for search & data extraction work as a local process; choose Fetch for search & data extraction as a local process. You can also run both side by side in one mcpServers block.
