Implementation Reference

• schema_engram_mcp/server.py:98-110 (handler)

  The handler implementation for the `db_schema_list` tool, which fetches a list of schema snapshots using the storage helper.

  def db_schema_list(
      workspace_id: str,
      connection_name: str | None = None,
      limit: int = 50,
  ) -> str:
      """Lista instantáneas guardadas (sin el cuerpo completo del esquema)."""
      rows = storage.list_snapshots(
          _get_conn(),
          workspace_id=workspace_id.strip(),
          connection_name=connection_name.strip() if connection_name else None,
          limit=min(max(limit, 1), 200),
      )
      return json.dumps({"snapshots": rows}, ensure_ascii=False)
