Latest update (11-11 00:00): Mastra adds background MCP tasks for long-running tool calls

Overview: Mastra adds tasks to its MCPServer and MCPClient so long-running tool calls can run in the background while the agent keeps responding, according to a Mastra blog post. The server returns a task ID immediately, and the client polls until the task is completed, failed, or cancelled.

The feature requires @mastra/mcp 2.7.0 or later and @mastra/core 1.81.0 or later. Mastra says the API is still experimental and may change between releases.
