How to Connect an MCP Server to Grok — Complete Guide 2026
Grok supports remote MCP connectors from its interface. Step-by-step guide to connecting any MCP server to Grok via grok.com, no code or installation required.
Grok, the AI assistant developed by xAI (Elon Musk's company), supports MCP (Model Context Protocol) connectors directly from its interface on grok.com. The process is close to Claude's: a few clicks, a URL, and your external tool is available in your conversations.
This guide details the exact steps.
What you need
A Grok account accessible at grok.com or from the X application.
Your MCP server URL — the server must be publicly accessible via HTTPS. Local servers will not work. The protocol must be Streamable HTTP or SSE.
Step 1 — Copy your connector URL
Retrieve the HTTPS URL of your MCP server. If you are using AIO Évolution, this URL is available in your dashboard, under the "MCP Connector" section.
Step 2 — Open the Connectors section in Grok
Log in at grok.com. Go to your account settings and navigate to the Connectors section.
Step 3 — Add a new connector
On the Connectors page, click the "+" icon to add a new connector.
Step 4 — Choose a custom connector
In the menu that appears, select the "Custom connector" option.
Step 5 — Name and paste the URL
A form opens. Fill in:
- Name — a readable name to find your connector easily (e.g. "AIO Therapeutic")
- URL — paste the HTTPS URL of your MCP server
Click "Add" to confirm.
Step 6 — Finalise the connection
Your connector appears in the list. Click "Connect" and follow the authentication process if your server requires it.
Once connected, the tools exposed by your MCP server are available in your Grok conversations.
What this changes in conversations
Once an MCP server is connected, Grok can call its tools directly from the chat. You don't need special syntax — Grok determines itself when a tool is relevant based on your request.
Grok's personality remains the same: direct, unfiltered, sharp. But it now applies to the data and tools exposed by your MCP server.
Concrete example: connecting AIO Évolution to Grok
AIO Évolution is a therapeutic MCP server compatible with Grok. The connection follows the steps above. Once connected, you have access to Brain AIO tools and symbolic draws from the All In One Method — with Grok's characteristic frankness as the mode of exploration.
For detailed screenshots of each step, see our visual installation guide — it includes the complete Grok-specific procedure.
Troubleshooting common issues
The connector is added but tools don't activate → Check that your MCP server is accessible from the internet. Test the URL in a browser — you should get a response, not a connection error.
Authentication fails → If your server requires authentication, check the authentication parameters provided by your MCP provider.
I can't find the Connectors section → Grok's interface evolves regularly. If you can't find the section, look in account settings or the advanced options of the interface.
