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)
