Why does a ClearRun MCP tool return 403 'API access requires a Pro plan or higher'?

The tool reports the API error. Code API_ACCESS_REQUIRED means the key is not a free developer key. A verified free account can create one developer key and use it with the MCP server.

Fix

  1. On a verified free account, create one developer key at api.clearrun.net/account/keys. Revoke an old key first if you already have one.
  2. Put that key in the MCP config.
  3. Restart your MCP host.

Scoring on a free account

A free developer key can call the MCP score, evaluate and chat tools. It returns the free verdict. Paste Check and signed-in chat on the site do not use the key.

A different 403

API_ACCESS_DISABLED means API access is off on a paid plan. That switch does not turn a free developer key off. See How to turn API access on or off.
