rebuild_metadata_index

Instructions

Rebuild the metadata index by scanning all SQL configs and Java files.

Use this tool when you've added new files or updated metadata annotations.
The index is automatically built on first search, but you can manually rebuild
it with this tool.

Args:
    config_directory: Path to the directory containing SQL config files
    code_directory: Path to the directory containing Java source files
    
Returns:
    A summary of the indexing operation

Implementation Reference

• trade_surveillance_mcp/server.py:440-473 (handler)

  The main asynchronous handler function for the 'rebuild_metadata_index' tool. It is decorated with @mcp.tool(), which registers it with the MCP server. The function rebuilds the metadata index by calling scan methods on the MetadataIndex instance and returns a summary dictionary.

  @mcp.tool()
  async def rebuild_metadata_index(
      config_directory: str = "./configs",
      code_directory: str = "./src"
  ) -> dict[str, Any]:
