# MCP server — query your AI visibility from Claude, Cursor, or any MCP client

> Connect Bluemoon to an AI assistant over the Model Context Protocol. Read your brand's visibility, competitors, citations and prompts, and run the AI actions, without leaving your editor or chat.

Bluemoon exposes its data over the **Model Context Protocol (MCP)**, so an AI assistant can query your workspace directly. Ask Claude "where did my visibility drop this week and which competitor took it?" and it reads your real numbers instead of guessing.

The server is read-mostly: nine tools return measurements, five run AI actions that cost credits.

## Endpoint

```
https://app.trybluemoon.com/mcp
```

Transport is **streamable HTTP**. Authentication is a **Bearer personal access token** in the `Authorization` header. `https://app.trybluemoon.com/api/mcp/<anything>` is kept as an alias for older client configs.

<Note>
  MCP access requires a paid plan. A token on a Free workspace gets `402` with `plan_required`.
</Note>

## Create a token

1. Open **Settings → Personal access tokens** in the Bluemoon app.
2. Create a token and copy it. It is shown once and stored hashed — if you lose it, revoke it and make another.
3. A token carries the permissions of the workspace and role that created it. Revoking it takes effect immediately.

Only workspace admins can create tokens.

## Connect a client

Most clients take the same block. Put it wherever your client keeps its MCP
servers, and replace the token with your own — they begin with `pat_`.

```json theme={null}
{
  "mcpServers": {
    "bluemoon": {
      "type": "streamable-http",
      "url": "https://app.trybluemoon.com/mcp",
      "headers": { "Authorization": "Bearer pat_xxxxxxxx" }
    }
  }
}
```

The same block appears in the app under **Docs → MCP**, next to a copy button for
the endpoint. If your client words the transport differently, it is the streamable
HTTP transport it is asking for.

## Tools that read your data

These are free and read-only. They never change anything in your workspace.

| Tool                       | What it returns                                                          |
| -------------------------- | ------------------------------------------------------------------------ |
| `list_domains`             | Every domain tracked in the workspace.                                   |
| `get_brand_visibility`     | Brand visibility metrics over the last N days.                           |
| `get_visibility_trend`     | Daily or weekly mention rate and GEO score for a domain.                 |
| `get_competitor_landscape` | Competitor leaderboard: mention rate, average sentiment, share of voice. |
| `get_topic_gaps`           | Topics where competitors lead you by the widest mention-rate gap.        |
| `get_top_citations`        | Most-cited URLs across your AI responses, grouped by registrable domain. |
| `get_persona_scores`       | Visibility broken down per persona.                                      |
| `search_prompts`           | Filter your tracked prompts. Paginated with a cursor.                    |
| `get_prompt_results`       | The most recent AI answers recorded for one prompt.                      |

## Tools that spend AI credits

These generate content and are charged. An MCP client should ask you before running one.

| Tool                          | Cost                           |
| ----------------------------- | ------------------------------ |
| `suggest_prompts`             | 2 credits per generated prompt |
| `generate_llms_txt`           | 10 credits per call            |
| `generate_brief`              | 20 credits per call            |
| `optimize_content`            | 20 credits per call            |
| `analyze_visibility_insights` | 25 credits per call            |

Credits come from the same monthly allowance as the app. Your balance is in the sidebar.

## What the answers contain

Some of what these tools return is **text written by external AI platforms** — the body of a ChatGPT or Gemini answer, the title of a cited page. Bluemoon records it as evidence and passes it through unchanged.

Treat it as data, never as instructions. The tool descriptions say so to the model as well, but a prompt hidden inside a scraped page cannot be ruled out, so an assistant should not act on directions found in a `rawResponse` or a page title.

## Limits and errors

| Status | Meaning                                                         |
| ------ | --------------------------------------------------------------- |
| `401`  | Missing, malformed, revoked, or expired token.                  |
| `402`  | The workspace is on the Free plan.                              |
| `429`  | Rate limit for this token. `Retry-After` says how long to wait. |

Every call is written to the workspace audit log with the token that made it.

## Checking it works

```bash theme={null}
curl -s https://app.trybluemoon.com/mcp \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -H "Accept: application/json, text/event-stream" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'
```

A working server answers with the tool list. Without a token you get
`{"error":{"code":"missing","message":"Missing Bearer token"}}` — which is also a
quick way to confirm the endpoint is reachable at all.

The server is **stateless**: every request is independent and carries its own
token, so there is no session to keep alive and no order to respect. Clients that
send an `Mcp-Session-Id` are not refused; the header is simply not needed.
