Implementation Reference

• src/tools/redis_query_engine.py:28-43 (handler)

  The main handler function for the 'get_index_info' tool, decorated with @mcp.tool() for registration. It retrieves detailed information about a Redis search index using FT.INFO and returns it as a formatted JSON string, handling Redis errors gracefully.

  @mcp.tool()
  async def get_index_info(index_name: str) -> str:
      """Retrieve schema and information about a specific Redis index using FT.INFO.
  
      Args:
          index_name (str): The name of the index to retrieve information about.
  
      Returns:
          str: Information about the specified index or an error message.
      """
      try:
          r = RedisConnectionManager.get_connection()
          info = r.ft(index_name).info()
          return json.dumps(info, ensure_ascii=False, indent=2)
      except RedisError as e:
          return f"Error retrieving index info: {str(e)}"
