Implementation Reference
- src/tools/hash.py:81-100 (handler)The main handler function for the 'hgetall' tool. It retrieves all fields and values from a specified Redis hash key using RedisConnectionManager, converts bytes to strings if present, and handles Redis errors by returning an error message.
@mcp.tool() async def hgetall(name: str) -> dict: """Get all fields and values from a Redis hash. Args: name: The Redis hash key. Returns: A dictionary of field-value pairs or an error message. """ try: r = RedisConnectionManager.get_connection() hash_data = r.hgetall(name) return ( {k: v for k, v in hash_data.items()} if hash_data else f"Hash '{name}' is empty or does not exist." ) except RedisError as e: return f"Error getting all fields from hash '{name}': {str(e)}" - src/common/server.py:6-17 (registration)The load_tools function imports all modules in src/tools, which triggers the @mcp.tool() decorators to register the 'hgetall' tool (among others) with the MCP server.
