Troubleshooting

Missing or Invalid Headers
  • Cause: OAuth token not provided in request headers or incorrect format
  • Solution:
    1. Verify Authorization: Bearer YOUR_API_KEY and X-Mewcp-Credential-Id: CREDENTIAL-ID headers are present
    2. Check your credential is active in your MewCP account
Insufficient Credits
  • Cause: API calls have exceeded your request limits
  • Solution:
    1. Check credit usage in your Curious Layer dashboard
    2. Upgrade to a paid plan or add credits for higher limits
    3. Contact support for credit adjustments
Credential Not Connected
  • Cause: No Google account linked to your MewCP credential
  • Solution:
    1. Go to Credentials in your MewCP dashboard
    2. Connect your Google account via OAuth
    3. Retry the request with the correct X-Mewcp-Credential-Id header
Malformed Request Payload
  • Cause: JSON payload is invalid or missing required fields
  • Solution:
    1. Validate JSON syntax before sending (especially person and contact_group parameters)
    2. Ensure all required tool parameters are included
    3. Check parameter types match expected values
Server Not Found
  • Cause: Incorrect server name in the API endpoint
  • Solution:
    1. Verify endpoint format: {server-name}/mcp/{tool-name}
    2. Use correct server name from documentation
    3. Check available servers in your Curious Layer account
Google People API Error
  • Cause: Upstream Google People API returned an error
  • Solution:
    1. Check Google Workspace service status at Google Status Dashboard
    2. Verify your Google account has the required Contacts permissions (scope: contacts, contacts.readonly)
    3. Review the error message for specific details
