Implementation Reference
- src/tools/sorted_set.py:59-79 (handler)The zrem tool handler implementation, decorated with @mcp.tool() for MCP registration. It connects to Redis, calls zrem to remove a member from a sorted set, and returns a success or error message.@mcp.tool() async def zrem(key: str, member: str) -> str: """Remove a member from a Redis sorted set. Args: key (str): The sorted set key. member (str): The member to remove. Returns: str: Confirmation message or an error message. """ try: r = RedisConnectionManager.get_connection() result = r.zrem(key, member) return ( f"Successfully removed {member} from {key}" if result else f"Member {member} not found in {key}" ) except RedisError as e: return f"Error removing from sorted set {key}: {str(e)}"
- src/tools/sorted_set.py:59-59 (registration)The @mcp.tool() decorator registers the zrem function as an MCP tool.@mcp.tool()
