RAGFlow Server

A comprehensive Model Context Protocol (MCP) server for RAGFlow that provides full API access for semantic retrieval and knowledge base management.

Features

• Semantic Retrieval: Search across datasets using natural language queries
• Dataset Management: Create, list, update, and delete datasets
• Document Management: Upload, parse, list, download, and delete documents
• Chunk Management: Add, list, update, and delete document chunks
• Chat Assistants: Create and manage chat assistants with RAG capabilities
• Session Management: Create and manage chat sessions
• GraphRAG & RAPTOR: Build and query knowledge graphs (when supported by your RAGFlow instance)

Installation

Prerequisites

• Python 3.10+
• RAGFlow server running and accessible (v0.16.0+ for core features)
• RAGFlow API key

Note: GraphRAG and RAPTOR build APIs require RAGFlow v0.21.0 or later.

Install from source

git clone https://github.com/Juxsta/ragflow-mcp.git
cd ragflow-mcp
pip install -e .

Configure Claude Code

Add to your Claude Code MCP settings:

claude mcp add ragflow -e RAGFLOW_API_KEY=your-api-key -e RAGFLOW_URL=http://localhost:9380/api/v1 -- python -m ragflow_mcp.server

Or manually add to ~/.claude/settings.json:

{
  "mcpServers": {
    "ragflow": {
      "command": "python",
      "args": ["-m", "src.server"],
      "cwd": "/path/to/ragflow-mcp",
      "env": {
        "RAGFLOW_API_KEY": "your-api-key",
        "RAGFLOW_URL": "http://localhost:9380/api/v1"
      }
    }
  }
}

Usage Examples

Semantic Search

Query: "What is the main character's motivation?"
Dataset: your-dataset-id

Upload and Parse a Document

1. Upload: ragflow_upload_document_tool(dataset_id, file_path="/path/to/doc.pdf")
2. Parse: ragflow_parse_document_sync_tool(document_id)
3. Search: ragflow_retrieval_tool(query="your question", dataset_ids=[dataset_id])
