Claude Desktop
Claude Desktop connects with OAuth: add the server URL, approve in the browser, done. No browser or older plan? The headless guide has the mcp-remote bridge config.
Add a custom connector (recommended)
In Claude Desktop: Settings → Connectors → Add custom connector. Paste the server URL below as the Remote MCP server URL and complete the browser approval. No key to copy. Your client opens Unitpost in the browser — pick a workspace, approve the scopes, and you're connected. Tokens refresh automatically.
Remote MCP server URL https://mcp.unitpost.com/mcp Verify
The unitpost connector should show as connected with its tools available in chat.
Don't see it? Fully quit and reopen the client — closing the window is often not enough — then check again.
Send a test
Ask Claude to send an email from a verified domain and confirm it in Unitpost Activity.
No browser on this machine? For headless setups, CI, SSH, or clients that can only paste a key, use the API-key setup instead.
