Grok
Add the server URL as a remote HTTP MCP server and approve in the browser. The Unitpost plugin for Grok bundles this same server with the Unitpost skill.
Add the server
Add a remote HTTP MCP server with the URL below; Grok opens Unitpost in the browser to approve. No key to copy. Your client opens Unitpost in the browser — pick a workspace, approve the scopes, and you're connected. Tokens refresh automatically.
JSON{ "mcpServers": { "unitpost": { "type": "http", "url": "https://mcp.unitpost.com/mcp" } } }The plugin source is public at github.com/unitpostcom/unitpost-grok-plugin.
Verify
unitpost should show connected with tools like
email_sendandemail_domains_list.Don't see it? Fully quit and reopen the client — closing the window is often not enough — then check again.
Send a test
Ask Grok to send a test email from a verified domain, then 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.
