The Langflow Document Q&A Server allows you to query documents with natural language prompts. With this server, you can:
- Query Documents: Search through documents by providing natural language queries using the
query_docstool - Retrieve Answers: Get responses based on document content and your provided query
- Langflow Integration: Connect to a Langflow backend that processes and responds to queries
- Configurable API Endpoint: Set custom Langflow API endpoints via environment variables
- MCP Compliance: Integrate seamlessly with tools like Claude Desktop through Model Context Protocol
- Debugging Support: Use tools like the MCP Inspector for troubleshooting server communications
Enables document question-answering capabilities by connecting to a Langflow backend, allowing users to upload documents and query them using natural language through a Langflow Document Q&A Flow.
Langflow-DOC-QA-SERVER
A Model Context Protocol server for document Q&A powered by Langflow
This is a TypeScript-based MCP server that implements a document Q&A system. It demonstrates core MCP concepts by providing a simple interface to query documents through a Langflow backend.
Prerequisites
1. Create Langflow Document Q&A Flow
- Open Langflow and create a new flow from the "Document Q&A" template
- Configure your flow with necessary components (ChatInput, File Upload, LLM, etc.)
- Save your flow
2. Get Flow API Endpoint
- Click the "API" button in the top right corner of Langflow
- Copy the API endpoint URL from the cURL command
Example:
http://127.0.0.1:7860/api/v1/run/<flow-id>?stream=false - Save this URL as it will be needed for the
API_ENDPOINTconfiguration
Features

query_docs- Query the document Q&A system- Takes a query string as input
- Returns responses from the Langflow backend

Installation
To use with Claude Desktop, add the server config:
On MacOS: ~/Library/Application Support/Claude/claude_desktop_config.json
On Windows: %APPDATA%/Claude/claude_desktop_config.json
Installing via Smithery

Environment Variables
The server supports the following environment variables for configuration:
API_ENDPOINT: The endpoint URL for the Langflow API service. Defaults tohttp://127.0.0.1:7860/api/v1/run/480ec7b3-29d2-4caa-b03b-e74118f35facif not specified.
Debugging
Since MCP servers communicate over stdio, debugging can be challenging. We recommend using the MCP Inspector, which is available as a package script:
The Inspector will provide a URL to access debugging tools in your browser.
