### Answer
I don't have specific troubleshooting steps in the available documentation for when the MCP appears listed but won't enable or toggle on in Claude.
The setup guide mentions: [(1) ](
)
- When using the Retell AI MCP server for the first time, you may be prompted to grant permissions—you can choose "Always Allow" for seamless future use
- After completing the setup steps, you should find the Retell AI MCP server in your tools list in Claude, confirming successful integration
However, the documentation doesn't cover what to do when it appears listed but remains disabled.
Suggestions to try:
- Double-check that your Retell AI API token is valid and correctly placed in the JSON config
- Ensure Claude is fully quit and reopened (not just minimized)
- Verify the JSON syntax is correct (no trailing commas, proper formatting)
For this specific issue, I'd recommend reaching out directly to Retell AI support or checking their GitHub repository for known issues:
- [Retell MCP Server Repository (GitHub) ](
)
- [Contact Sales](
)
Would you like me to try to provide a general answer based on common MCP configuration issues?
