What's Wrong?

Attempted to use the Gmail connector's create_draft tool during a session. The call returned MCP error -32003: MCP tool call requires approval. A permission prompt appeared, I approved it (allowed the action in Google), but the retried tool call returned the identical error. Approved a second time with the same result. Never succeeded; worked around it by pasting the email manually.

Session also had frequent MCP server connect/disconnect cycling throughout (Gmail, Krisp, HubSpot, wiki, others repeatedly dropping and reconnecting), which may be related.

What Should Happen?

After approving the permission prompt, the create_draft tool call should succeed and create the Gmail draft. Instead it returns the same "requires approval" error even after approval was granted, twice in a row.

Error Messages/Logs

MCP error -32003: MCP tool call requires approval

Steps to Reproduce

1. Start a Claude Code session (cloud/remote execution environment) with the Gmail MCP connector connected and enabled in chat.
2. Ask the assistant to create a Gmail draft (invokes the Gmail MCP server's create_draft tool).
3. A permission prompt appears asking to Allow or Deny the action. Select Allow.
4. The tool call still returns: MCP error -32003: MCP tool call requires approval.
5. Retry the identical tool call. The permission prompt appears again; approve it again.
6. The same error recurs. The draft is never created.

Note: this occurred during a session where several other MCP connectors (HubSpot, a Krisp integration, a wiki server, Zoom) were repeatedly disconnecting and reconnecting throughout — may be a related factor.

Additional Information

Occurred in a cloud/remote Claude Code session (Claude Code on the web), not a local CLI session. Workaround: pasted the email content manually into a Gmail draft instead of using the tool.
