Implementation Reference

• src/mochow_mcp_server/server.py:530-543 (handler)

  The primary handler function for the 'describe_table' MCP tool. Decorated with @mcp.tool() for automatic registration. It fetches table details using the connector's describe_table_info method and returns a formatted string description.

  @mcp.tool()
  async def describe_table(table_name: str, ctx: Context = None) -> str:
      """
      Describe table details in the Mochow instance.
  
      Args:
          table_name (str): Name of the table to describe.
  
      Returns:
          str: A string containing the details of the table.
      """
      connector = ctx.request_context.lifespan_context.connector
      details = await connector.describe_table_info(table_name)
      return f"Table details named '{table_name}' in Mochow instance:\n{str(details)}"

• src/mochow_mcp_server/server.py:119-134 (helper)

  Supporting helper method in the MochowConnector class that interfaces with the underlying pymochow database to retrieve and return table schema/details as a dictionary.

  async def describe_table_info(self, table_name: str) -> dict:
      """
      Get detailed information about a table.
  
      Args:
          table_name (str): Name of the table.
  
      Returns:
          dict: A dictionary containing table details.
      """
      if self.database is None:
          raise ValueError("Switch to the database before describe table")
      try:
          return self.database.describe_table(table_name).to_dict()
      except Exception as e:
          raise ValueError(f"Failed to get table detail info: {str(e)}")

• src/mochow_mcp_server/server.py:530-530 (registration)

  The @mcp.tool() decorator on the describe_table function registers it as an MCP tool with FastMCP.

  @mcp.tool()

• src/mochow_mcp_server/server.py:531-539 (schema)

  Input schema defined by function signature (table_name: str) and docstring; output is str.

  async def describe_table(table_name: str, ctx: Context = None) -> str:
      """
      Describe table details in the Mochow instance.
  
      Args:
