One connection uses one authentication method

ChatGPT and Claude.ai use OAuth: paste https://krexel.com/api/mcp and let OAuth start automatically. Local coding tools use krexel-mcp with KREXEL_API_KEY. Do not combine the two methods, paste an API key into an OAuth form, or manually register an OAuth client for ChatGPT or Claude.
