If you have added tools to your Zapier MCP server but they do not appear in your MCP client, it may be using a cached tool list, or the tools may not be configured correctly. This article covers how to refresh the tool list and verify your setup.

​
Symptom

You added tools to your MCP server, but they do not appear in your MCP client.

​
Causes

  • Your MCP client cached an older tool list and needs a manual refresh.
  • The tools are not configured correctly on your server.
  • An app connection has expired.
  • Your server URL or connection token is incorrect in your MCP client’s configuration.

​
How to fix it

1

Refresh your MCP client's tool list

Some MCP clients cache the tool list and need a manual refresh:
  • ChatGPT: Go to Connector Settings, select your Zapier connector, and select Refresh.
  • Claude Desktop: Restart the application.
  • Cursor or VS Code: Reload the window or restart the editor.
  • Other MCP clients: Check the MCP client’s documentation for how to refresh the tool list.
2

Check tool configuration

Go to the Zapier MCP dashboard and select your server.
  • Managed mode: Confirm the tools appear on the Configure tab and are enabled.
  • Agentic mode: Tools are discovered dynamically. Check the Configure tab for any warning icons on app connections rather than checking for individual tools.
3

Check your app connection

If a tool shows an alert icon alertCircleFill beside its name, select the menu icon navMoreHoriz beside the app name and select Update authentication to fix the connection.
4

Verify your connection details

For OAuth MCP clients, disconnect and reconnect using the link icon Connect tab. For unlisted MCP clients using a connection token, confirm the server URL in your MCP client matches the one shown on the link icon Connect tab in the Zapier MCP dashboard.
