MCP Server Overview

The ragieai/mcp-server MCP server exposes Ragie knowledge-base retrieval to MCP-compatible clients through stdio. Its single `retrieve` tool searches for relevant content chunks and supports result limits, reranking, and recency preferences. Use it when an agent needs context from a Ragie knowledge base, including knowledge assembled from sources such as Google Drive, Notion, or JIRA. This repository is deprecated because Ragie now provides MCP natively through a streamable HTTP server.

Primary Use Cases for MCP Server:
  • Search a Ragie knowledge base from Claude Desktop
  • Retrieve company context inside Cursor
  • Favor recent documents during knowledge-base searches
  • Limit or rerank retrieved content chunks
