# Grok



Grok comes up in two ways: as an MCP client driving your workspace, and as a
reader of your website. Surface covers the first fully and the second only in
part.

## 1. Grok Driving Your Workspace [#1-grok-driving-your-workspace]

Surface's MCP server uses the standard transport: **Streamable HTTP, one URL, a
Bearer token**.

```
URL:     https://app.withsurface.com/mcp
Header:  Authorization: Bearer <your-api-key>
```

<Info>
  xAI's MCP support differs between the Grok apps, the console and the API. Use
  whatever MCP entry your Grok surface exposes and give it those two values. If it
  takes a URL, `?tools=` and `?readonly=1` ride it. See
  [Tool bundles](/mcp-server/tool-bundles).
</Info>

If you are building against the xAI API, Surface is just an MCP server: use any
MCP client library, and every tool in the
[tool reference](/mcp-server/tools) is available.

**Start read-only.** One query parameter removes every write tool:

```
https://app.withsurface.com/mcp?tools=insights&readonly=1
```

## 2. Grok and Your Website [#2-grok-and-your-website]

This needs no setup beyond the
[Surface Tag](/platform/traffic/surface-tag). Two limits: Surface does not score
xAI, and Grok is not one of the engines the AI traffic breakdown is documented
to name.

**As an answer engine.** [AI Visibility](/platform/ai-visibility/overview) scores
your presence per model, and the four scored today are ChatGPT, Gemini,
Perplexity and Claude. &#x2A;*Grok is not one of them.** The prompt set, competitor
set and [cited sources](/platform/ai-visibility/cited-sources) are shared across
the models that are.

**As a referrer.** [Traffic analytics](/platform/traffic/analytics) splits AI
referrals out by engine, with an average lead score attached. The engines named
in those docs are ChatGPT, Perplexity, Claude and Gemini. Build an `ai-referrals`
[segment](/platform/leads/segments) and read what actually lands in it.

<Info>
  Whether a Grok click-through is broken out under its own engine, folded into
  another bucket, or absent is not something these docs can tell you. Check the AI
  traffic breakdown in your own workspace, or ask your Surface contact.

<Tip>
  Blocking AI crawlers in `robots.txt` is right for some businesses and wrong for
  most B2B ones. Check what yours does rather than inheriting it from a template.
