Implementation Reference

• src/qgis_mcp/qgis_mcp_server.py:146-151 (handler)

  MCP tool handler for the 'ping' tool. Proxies the ping command to the underlying QGIS socket server and returns the JSON-formatted response.
  @mcp.tool() def ping(ctx: Context) -> str: """Simple ping command to check server connectivity""" qgis = get_qgis_connection() result = qgis.send_command("ping") return json.dumps(result, indent=2)
• qgis_mcp_plugin/qgis_mcp_plugin.py:171-173 (handler)

  Core implementation of the ping command in the QGIS MCP socket server, returning a simple pong response.
  def ping(self, **kwargs): """Simple ping command""" return {"pong": True}
• qgis_mcp_plugin/qgis_mcp_plugin.py:133-149 (registration)

  Registration of the 'ping' handler (and other commands) in the QGIS MCP socket server's command dispatcher.
