Implementation Reference

• src/zabbix_mcp_server.py:663-690 (handler)

  The complete implementation of the 'template_update' MCP tool. This handler function is registered via the @mcp.tool() decorator. It performs read-only validation, retrieves the Zabbix API client, constructs update parameters conditionally, calls the Zabbix template.update API method, and returns a formatted JSON response. The function signature and docstring define the input schema.

  @mcp.tool()
  def template_update(templateid: str, host: Optional[str] = None,
                      name: Optional[str] = None, description: Optional[str] = None) -> str:
