Redis MCP Server

A Model Context Protocol (MCP) server for Redis operations built with FastMCP.

Features

• Core Redis operations: get, set, delete, list
• Bulk operations: mget, mset
• Pattern-based key scanning
• Connection pooling for efficient Redis access
• Multiple transport support (stdio, SSE, streamable-http)
• Environment-based configuration
• Type hints and comprehensive error handling

Installation

From PyPI

pip install redis-mcp

Or using uv:

uv tool install redis-mcp

From Source

# Clone the repository
git clone https://github.com/yourusername/redis-mcp.git

Available Tools

• get: Retrieve a value by key
• set: Store a key-value pair with optional expiry and conditions
• delete: Remove one or more keys
• list: List keys matching a pattern
• mget: Get multiple values in one operation
• mset: Set multiple key-value pairs in one operation
• scan: Iterate through keys matching a pattern without blocking

Example Usage

from fastmcp import Client

async def main():
    async with Client("http://localhost:8000/sse") as client:
        # Set a value
        await client.call_tool("set", {"key": "user:123", "value": "John Doe"})
        
        # Get a value
        result = await client.call_tool("get", {"key": "user:123"})
        print(result)  # "John Doe"
        
        # List keys
        keys = await client.call_tool("list", {"pattern": "user:*"})
        print(keys)  # ["user:123"]
