Cursor plugin that connects agents to Similarweb through Similarweb's official remote Model Context Protocol server.
Pull Similarweb digital-intelligence data — website traffic and engagement, competitor comparison, audience demographics, and keyword metrics — for research without leaving the editor.
- Open Cursor Settings → Plugins.
- Search for Similarweb.
- Click Install, then set your Similarweb API key (below).
Or run /add-plugin similarweb in chat.

}Auth is a Similarweb API key sent in an api-key header (lowercase, hyphenated — not Authorization). Copy it from Account Settings → Data Tools → REST API, then set it in Dashboard → Plugins → Configure.
You need a Similarweb subscription with API access — API-only, Business, or Enterprise. Calls debit standard API data credits. If the REST API section is not visible in your account settings, an account admin has to generate the key.
| Category | Capabilities |
|---|---|
| Web metrics | Traffic and engagement, traffic sources, website rank, similar sites, referrals, audience overlap, demographics, technologies, segments, and PPC spend |
| Search metrics | SERP players and SERP clicks |
| App metrics | App install penetration, app store rank, and app details |
The hosted runtime is the source of truth for tool names and schemas.
- Tool calls run with the permissions and credit balance attached to the API key.
- Similarweb's own Cursor guide routes through
npx mcp-remote. That is not necessary — Cursor connects to the remote endpoint directly and sends theapi-keyheader, which is the same shape Similarweb documents for Microsoft Copilot Studio. - Similarweb runs two documentation portals,
docs.similarweb.comanddevelopers.similarweb.com, whose MCP paths drift. Both give the same endpoint.
