@teghoz did this happen when using a specific MCP server? Or when? Could you share config?

Fixed by #11792.

What was happening: Your model wasn't recognized in Continue's native tool support list (PROVIDER_TOOL_SUPPORT), so it fell back to a text-based tool calling format injected into the system message. When the model didn't follow that format exactly, the parser threw "Invalid tool name". This PR adds your model family to the allowlist so it uses native tool calling instead.

Workaround (if you're on an older version): In your model config, set "capabilities": { "tools": true } to force native tool calling.
