Hatmanstack Ragstack MCP server — FAQ

Common questions about connecting and running Hatmanstack Ragstack.

  • What is RAGStack and how does this MCP server connect to it?

    RAGStack is a serverless knowledge base platform on AWS. This MCP server acts as a bridge, letting you search, upload documents, and chat with your RAGStack instance via Claude or other AI tools. You connect it by providing your GraphQL endpoint and API key from the RAGStack Dashboard.

  • How do I get my RAGSTACK_GRAPHQL_ENDPOINT and RAGSTACK_API_KEY?

    Both credentials are available in your RAGStack Dashboard under Settings. Copy the GraphQL API URL and generate or retrieve your API key, then set them as environment variables when running the MCP server.

  • Can I use this MCP server to upload and search documents in the same conversation?

    Yes. The server supports upload, search, and chat capabilities, so you can upload a document and immediately search or query it within the same session.

  • What transport protocol does this MCP server use?

    It uses stdio (standard input/output), which is the most common transport for local MCP integrations. Install it via `uvx ragstack-mcp@0.1.4` and configure your AI tool to spawn it as a subprocess.

  • Is there a cost to using RAGStack with this MCP server?

    RAGStack is a managed AWS service with its own pricing model. Check the RAGStack documentation or AWS console for current pricing; the MCP server itself is open-source and free.
