Hey, thanks for the report.

Looks like a known issue that showed up in version 2.3.41 - MCP servers appeared connected, but the agent couldn’t see their tools. It got fixed end of January.

Your version (2.3.34) is older than when the bug started. Can you clarify:

- When exactly did the issue start?
- Did you try updating to the latest stable version?

If the problem sticks around after updating, try this workaround:

- Open a new chat
- Ask the agent: “list all MCP tools you have access to”
- After that, the agent should see the tools in this session

For debugging, I need the Request ID from the broken chat (three dots top right in chat \> Copy Request ID). Can you share it?
