MCP
Test and troubleshoot
Verify the connection with the MCP Inspector and fix common errors.
MCP Inspector
The MCP Inspector is the official tool for exploring an MCP server: it lists every available tool and lets you run calls by hand.
Terminal
npx @modelcontextprotocol/inspectorThen connect with transport type Streamable HTTP and URL https://whazzup.io/mcp. The inspector opens the OAuth flow in your browser.
Check the connection
The server exposes a check_connection tool that verifies the token, plan and workspace access and reports what works. Ask your assistant to „check the Whazzup connection" or run the tool in the inspector. Failed calls also appear in Whazzup under Settings → MCP server and are kept for 30 days.

npx mcp-remote https://whazzup.io/mcpCommon errors
| Error | Meaning | What to do |
|---|---|---|
| 401 unauthorized | The token is missing, expired or revoked. | Disconnect the connector in your AI tool and add it again to restart the sign-in flow. |
| 403 / Unlimited required | The MCP server is part of the Unlimited plan. | Upgrade in Whazzup under Settings → Billing. |
| 429 rate_limited | More than 120 read or 30 write calls per minute. | Wait a minute and retry; group questions instead of firing many calls. |
| ChatGPT asks for a client ID | The connector was created before the server was reachable. | Delete the connector and add it again – clients register automatically. |
| Stale auth cache (mcp-remote) | An old token is cached locally. | Run: pkill -f mcp-remote && rm -rf ~/.mcp-auth, then reconnect. |
