Mastra ​

Mastra agents, through the model router's custom endpoint.

Connect ​

ts
const agent = new Agent({
  id: "plugboard-agent",
  name: "Plugboard",
  instructions: "Be concise.",
  model: { id: MODEL, url: URL, apiKey: KEY },
  tools: { get_weather: weather },
});
  • id needs a provider prefix: plugboard/fast routes to your url and sends fast. A bare fast fails with Failed to resolve model configuration, and openai/fast goes to OpenAI.
  • url is the /v1 base; don't add /chat/completions.
  • Set api: "responses" on the model object to use the Responses API instead of Chat Completions.

What works ​

agent.generate, agent.stream, and tools made with createTool.

Limits ​

  • Mastra requests no stream usage, so streamed answers carry no token counts.
