How do I let Grok take actions on websites?

By Andrey Marey, Founder of AgentWeb · As of Oct 20, 2026

Short answer. Connect AgentWeb's MCP server, https://mcp.agentweb.us/mcp, to Grok. Grok then gets typed web actions on 1,462 real sites (as of Oct 20, 2026): order on Uber Eats, book on SevenRooms, post and reply on X, and message on LinkedIn from your own accounts, at $0.05 per completed action with failed actions refunded.

Set it up

1. Grok app: open grok.com/connectors, choose New Connector, then Custom, and enter the URL https://mcp.agentweb.us/mcp with your AgentWeb key as the authorization.
2. Grok CLI: run grok mcp add --transport http agentweb https://mcp.agentweb.us/mcp --header "Authorization: Bearer aw_YOUR_KEY".
3. xAI API: add a remote MCP tool with server_url set to https://mcp.agentweb.us/mcp, server_label set to agentweb, and authorization set to your aw_ key.
4. Ask for a task. Grok checks list_actions for the site and calls execute.
