Hosting

Remote, vendor-hosted

Transport

Streamable HTTP (MCP endpoint documented; some client setup uses mcp-remote bridge)

Endpoint

https://mcp.similarweb.com

Authentication

Similarweb API key and eligible subscription (API-only, Business or Enterprise). Calls consume data credits.

Requirements

• Similarweb subscription with API access (API-only, Business or Enterprise plans as documented)
• Active Similarweb API key
• MCP-compatible client

Setup steps

1. Get the API key from Similarweb User Settings ? API Access. If no key is available, the current plan may not include API access; contact the account manager.
2. Add https://mcp.similarweb.com as a hosted MCP connection and configure the api-key header in the client's protected local secret store. For Cursor, Similarweb documents npx -y mcp-remote@latest https://mcp.similarweb.com --header api-key:<API_KEY>.
3. Reconnect the client and confirm the server is active. Use a harmless website traffic lookup to verify data access.
4. Monitor API usage under User Settings ? API Access ? Usage; MCP consumes the same API credits as normal API requests.

The official docs enumerate capability categories and available metrics, while access depends on API subscription and credits. These 18 rows preserve documented labels but are not asserted as a complete account-specific MCP tools/list.
