Most findings match Markdown delimiters, documented service URLs, configuration paths, or legitimate authentication checks. Two findings identify one credential-exposure risk: shell expansion puts the API key into CLI arguments, potentially exposing it through process inspection. No evidence found of prompt injection, malicious exfiltration, or host reconnaissance in the reviewed skill text.

Was Sie erstellen können

Configure an editor connection

Connect Cursor to Cooper Email through OAuth and verify inbox access without sending messages.

Restore a failed integration

Identify whether an authentication error comes from missing sign-in, an unavailable environment variable, or limited key permissions.

Connect a conversational assistant

Add a Cooper Email connector in Claude and complete the OAuth consent flow.

Diese Prompts ausprobieren

Connect with OAuth

Help me connect Cooper Email MCP in Cursor using OAuth. Ask before changing configuration or creating an account.

Verify an existing connection

Verify my Cooper MCP connection with cooper_whoami and cooper_list_inboxes. Report authentication type and success without exposing credentials or sending mail.

Diagnose authentication failure

Diagnose my Cooper MCP 401 error in Claude Code. Check sign-in and variable availability without printing secrets or expanding keys into commands.

Investigate permissions and discovery

Investigate Cooper MCP discovery and 403 errors in my client. Compare identity scope with required permissions and propose minimal changes before applying them.

Bewährte Praktiken

Prefer OAuth; otherwise use supported secret references and keep keys out of chat, command arguments, and committed files.
Verify connections with read-only identity and inbox checks before attempting mail operations.
Ask before creating accounts or changing permissions, and consult the live catalog rather than a fixed tool count.

Vermeiden

Pasting API keys into chat or expanding them into CLI header arguments.
Creating a new account to resolve an existing account authentication failure without user approval.
Using setup troubleshooting as permission to send messages or broaden account access.

Häufig gestellte Fragen

Does this skill run a local MCP server?

No. It guides connections to the hosted Cooper Email Streamable HTTP endpoint.

Which clients have setup guidance?

The skill covers Cursor, Claude Code, Claude connectors, and ChatGPT. It links configuration references for VS Code, Windsurf, Codex, and Goose.

Is an API key required?

No. Supported clients can use OAuth. API-key headers are an alternative for clients or scripts without OAuth.

Can this skill send or manage email?

That is outside its scope. Use the separate Cooper mail skills after the connection works.

How can I test the connection?

Reload the client, finish sign-in, and run cooper_whoami and cooper_list_inboxes as read-only checks.

What does a 401 error usually mean?

Sign-in may be incomplete, the credential may be invalid, or the API-key environment variable may be unavailable to the client.
