Implementation Reference

• redshift_mcp_server.py:96-115 (handler)

  The core handler function for the 'redshift_describe_table' MCP tool. It is registered via the @mcp.tool() decorator. The function builds a SQL query to retrieve column metadata from the information_schema and delegates execution to the 'redshift_query' tool, returning the JSON results.

  @mcp.tool()
  def redshift_describe_table(table_name: str, schema: str = "public") -> str:
