### Answer When you're having trouble publishing a prompt after adding an MCP server, here are the most common troubleshooting steps: [(1) ]() Verify MCP Server Status - Ensure your MCP server is actually running and responding - The server might appear up but not properly expose the tools Check Server Logs - Review MCP server logs for errors that aren't showing in the UI - Authentication or configuration issues often appear here Restart Connection - Try disconnecting and reconnecting the MCP server completely - This resolves many tool discovery failures Configuration Requirements [(2) ]() When adding your MCP server, make sure you've entered: - MCP Server Endpoint URL - Request Headers (if required, such as API keys) - Query Parameters (if needed) Verify Available Tools [(1) ]() You can verify your MCP tools are properly configured using the Get MCP Tools endpoint:

javascript
import Retell from 'retell-sdk';
const client = new Retell({
 apiKey: 'YOUR_RETELL_API_KEY',
}) ;
const mcpToolDefinitions = await client.mcpTool.getMcpTools('oBeDLoLOeuAbiuaMFXRtDOLriTJ5tSxD', {
 mcp_id: 'mcp-server-1',
}) ;
console.log(mcpToolDefinitions) ;

The issue is usually an MCP server configuration or authentication problem rather than a Retell AI platform issue.
