Agencies with many clients

  • On the Allow screen, pick which client brands the connection sees.
  • Set a default brand. Then your AI tool does not ask each time.
  • Give each client its own connection if you want to keep them apart.
  • Several Nenn logins on one computer? Set MCP_REMOTE_CONFIG_DIR for each mcp-remote.

Limits and usage

See drafts and calls for each connection in Nenn, under Settings, then AI tools (MCP).

Limits by planOpen AI tools in Nenn

Data and safety

  • Data you open in the chat goes to your AI provider. Their terms apply.
  • Read access shows checks, questions and articles. Draft access also saves drafts.
  • Each connection sees one workspace. Revoke it any time in Settings.
  • Drafts never publish. You approve them in Nenn.

Troubleshooting

The tool says 401 or asks me to reconnect

Your sign-in expired or was revoked. Remove Nenn in the tool and add it again.

It says I have no brands

The connection may see only some brands. Reconnect and pick the brands on the Allow screen.

It says MCP is not on my plan

Check your plan in Nenn under Plans. MCP needs an active trial or a paid plan.

A call times out

Try again in a minute. An article brief can take up to 20 seconds.

Claude does not let me add another connector
