Cursor Agent

The Ahrefs homepage pointed at docs.ahrefs.com/mcp/docs/introduction, a path I could not confirm resolves — Ahrefs' own archived repo and third-party indexes cite three different intro URLs. Point at ahrefs.com/mcp and the help centre article instead, both of which are live, and spell out the MCP-key header as an alternative to OAuth. Add Similarweb's Cursor integration guide.

Similarweb
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.
Install
- 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.
Before you connect
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.
What agents can do
| 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.
Notes
- 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.
