Help needed: Openrouter model connection problem

[wxs659]

Hi there,

I'm having problems connecting models in Openrouter, my configuration as follow:

openai:
    base_url: "https://openrouter.ai/api/v1"
    default_model: qwen/qwen3-235b-a22b:free

at runtime I got error:
[mcp_agent.executor.executor] Error executing task: Error code: 404 - {'error': {'message': 'No endpoints found that support tool use. To learn more about provider routing, visit: https://openrouter.ai/docs/provider-routing', 'code': 404}}
[mcp_agent.workflows.llm.augmented_llm_openai.agent] Error: Error code: 404 - {'error': {'message': 'No endpoints found that support tool use. To learn more about provider routing, visit: https://openrouter.ai/docs/provider-routing', 'code': 404}}

Anyone has idea?

Cheers,

Hi @wxs659, based on what I saw on OpenRouter’s model page (filtered by tools support), it looks like the qwen/qwen3-235b-a22b:free model doesn’t support tool use. Only the qwen/qwen3-235b-a22b version does. Let me know if thats fixes the issue!

HI @StreetLamb, I think you are correct, I used the wrong model. Thanks.
