Google Auth error with "Google Send Email" tool

[jerlyjelly]

I get the following error (see screenshot) when trying Google Send Email tool on the hosted demo.

Could you please update the OAuth settings ? Thanks in advance

I think this is actually due to another issue. Basically, the MCP spec supports pagination, which the Arcade server implements. Their TS SDK implements this properly, however their PY SDK does not. Since the web client uses the TS SDK, we can properly fetch & list all of the tools from Arcade, with pagination. This however can lead to issues, because the agent (written in PY, uses the MCP PY SDK) then can not fetch any tools past the first page (the issue w/ the MCP PY SDK is it doesn't pass the cursor properly, so you can't fetch more than the first page). This means you can enable a tool on the website, but the agent won't actually be able to load it. The error you're seeing is likely the LLM hallucinating a Google OAuth link, which errors because it's not a real link. The Arcade team put up a PR in the MCP PY SDK, so whenever this gets released, the issue you're seeing will be fixed.

Sorry you're running into this issue :/
