Two ways to connect, same result

Sign in with Pink

For apps a person uses: Claude, ChatGPT, Claude Code. The app opens Pink's sign-in page, you paste the admin key, choose which agent the app acts as, and click Allow. The app keeps a token for that agent. Standard OAuth 2.1 with PKCE; the app registers itself.

Agent key

For code, IDEs and automation: Cursor, Gemini CLI, the OpenAI and Anthropic APIs, LangChain, n8n. Paste one agent's key as the Authorization header, or put it in the URL for tools that cannot set headers. The key is the agent's identity and is bounded by its budget and rules.

Not on the list?

Anything that speaks MCP over Streamable HTTP connects the same way; see the official SDK guide. Anything else can use the REST mirror. Tell us what you use at [email protected] and we will add a guide.
