The MCP server now supports OAuth: ChatGPT, Claude.ai, and other OAuth-capable clients open a sign-in on karma.domains — you approve access on the consent page, with no need to paste a key by hand.
A Pro plan or higher is required. After sign-in, the assistant works with your account: auction and expired search, favorites, filters, annotations, share links, and SEO enrich — the same 31 tools as before.
How to connect
ChatGPT / Claude.ai — add the MCP URL https://mcp.karma.domains/mcp, choose OAuth (or Sign in), and finish browser login.
Cursor, VS Code, and other IDEs — still use a Bearer API key from Profile → Settings. OAuth and the key work side by side; x402 for agents is unchanged.
Client instructions are on the MCP landing page. If MCP was already connected with a key, you do not have to change anything: OAuth is an extra way to sign in.
