# MentionsAPI MCP Server
[](https://www.npmjs.com/package/@mentionsapi/mcp)
[](LICENSE)
Ask your AI agent whether AI recommends your brand. **MentionsAPI** tracks brand visibility across **every AI search surface** — ChatGPT, Claude, Gemini, Perplexity, Google AI Overviews, Google AI Mode, and Bing Copilot — and this MCP server puts that data inside any MCP-compatible client.
Ask in plain English. Get structured data back.
```
You: "Is HubSpot mentioned when users ask ChatGPT about CRMs?"
Claude: [calls mentions_check via MCP]
"Yes — ranked 3rd in ChatGPT's answer. Top 3:
HubSpot, Salesforce, Pipedrive. Fan-out queries
issued during search: ..."
```

## Two ways to connect
### Option 1 — Remote server (recommended, zero install)
**`https://api.mentionsapi.com/mcp`** — Streamable HTTP with OAuth (one-click on claude.ai) or `Authorization: Bearer lvk_live_...`.
- **claude.ai / Claude Desktop:** Settings → Connectors → Add custom connector → paste the URL above, then approve via OAuth.
- **Claude Code:**
```bash
claude mcp add --transport http mentionsapi https://api.mentionsapi.com/mcp
```
- **Any Streamable-HTTP client:** point it at the URL and send your API key as a Bearer token.
### Option 2 — Local stdio server (npm)
```bash
npx -y @mentionsapi/mcp@latest
```
#### Claude Code (`~/.claude.json`)
```json
{
"mcpServers": {
"mentionsapi": {
"command": "npx",
"args": ["-y", "@mentionsapi/mcp@latest"],
"env": { "MENTIONSAPI_KEY": "lvk_live_..." }
}
}
}
```
#### Cursor (`~/.cursor/mcp.json`) — same shape
#### Windsurf (`~/.codeium/windsurf/mcp_config.json`) — same shape
#### ChatGPT Plus — see [docs/mcp/chatgpt-plus](https://mentionsapi.com/docs/mcp/chatgpt-plus)

## Error handling
The MCP returns structured errors the AI agent can relay to you in plain English:
- **`auth_required`** — no API key set; includes signup URL
- **`auth_invalid`** — key was rejected; rotate at /app/keys
- **`insufficient_balance`** — wallet empty; top-up URL included
- **`rate_limit_exceeded`** — includes `retry_after_seconds`
- **`mode_roadmap`** — for `deep`/`change_track` (Q3 2026)
The server starts even without an API key — your AI agent will guide you through setup the first time you call a tool.
