Troubleshoot: Authorization with the MCP server failed in Funnel MCP

Resolve Funnel MCP connection failures in Claude that show an authorization error with an ofid support reference before you can use MCP tools.

Problem summary

You try to connect Funnel MCP in Claude and authorization fails before you can use any Funnel MCP tools. The error asks you to check credentials and permissions and includes an ofid_ support reference.

​

Error message or symptoms

Authorization with the MCP server failed. You can check your credentials and permissions. If this persists, share this reference with support: ofid_xxxx

​

Claude shows this during the connection or authorization step. The ofid_ value is Claude's reference for the failed attempt, not a Funnel ID. It's different for each failure and isn't your password or API key.

​

This is not the same as a token_exchange_failed error on tool calls after OAuth appears to succeed. If OAuth completes but tool calls fail afterward, that is a separate issue.

​

When does this occur

  • When you add or reconnect Funnel MCP in Claude, for example from Claude's connector directory

  • During the authorization step, before any Funnel MCP tool calls succeed

  • When your MCP server URL and Funnel sign-in look correct but the client still cannot authorize

​

Root cause

Intermittent MCP authorization issues

​

Solution

  1. Confirm your Remote MCP server URL matches your Funnel region. Use the global URL if you sign in at app.funnel.io and the EU URL if you sign in at app.eu.funnel.io:

    ​

    • Global (default): https://mcp.ai.funnel.io/mcp

    • EU: https://mcp.eu.ai.funnel.io/mcp

    ​

  2. Confirm you can sign in to Funnel in your browser with the same account you use for MCP authorization.

    ​

  3. In Claude, remove the Funnel connector, add it again with the correct URL and complete OAuth in a new chat or session.
