MCP > Creator connection failing with Claude

MCP > Creator connection failing with Claude

I'm trying to get claude to access any of my Zoho Creator apps and it keeps failing. I have enabled all tools for creator and ensured in claude settings that everything is authorised. Here is what claude says :

Unfortunately, the error messages I'm receiving are quite generic - they just say "Error occurred during tool execution" without any specific details like HTTP status codes, error messages from Zoho's API, or diagnostic information.

When you query Zoho support, I'd suggest asking:

  1. Regional endpoint handling: You're using zoho.eu - does the MCP connector need specific configuration for EU data centres versus the default .com domains?
  2. API scopes required: What specific OAuth scopes are needed for the Creator API operations (getApplications, getReports, getCreatorRecords, etc.)?
  3. Account owner name format: Should the account name be formatted differently in API calls? eg mycompanyltd
  4. Error logging: Is there a way to get more detailed error logs or diagnostic information from the MCP connector to see what's actually being sent to/received from Zoho's API?
  5. Test endpoint: Is there a simple "health check" or test endpoint they'd recommend trying first to verify the connection is working?

The fact that every single endpoint fails consistently suggests it's a fundamental connection or authentication issue rather than a problem with specific operations.
