Concrete capability record
Data, retrieval, actions, identity, and operating limits
A field-by-field summary of what the reviewed first-party references actually support. Publisher update dates and BYO-UI review dates are shown separately below.
02 · Data you can retrieve
Retrieve website traffic and engagement, unique and returning visitors, technology adoption, demographics, SERP players and clicks, mobile-app install penetration and ranks, app details, and other datasets included in the account subscription.
03 · Actions and write paths
The audited official MCP catalog describes analytics retrieval tools and does not document a mutation tool. Keep the MCP profile read-only unless Similarweb publishes and the customer enables a state-changing tool.
04 · Authentication and permissions
Connect to the hosted endpoint with an active Similarweb API key. Administrators create keys for users and can control activation; available datasets, geographies, and historical ranges follow the user's API subscription.
05 · Monitoring, approval, and recovery
API administrators manage key issuance and activation, while account entitlements constrain the accessible datasets and history. MCP requests consume the same data-credit pool as API requests, so date range, granularity, metrics, and endpoint selection are operational controls.
06 · Limits and caveats
MCP requires API access through an API-only, Business, or Enterprise subscription and an active key. Credit cost varies with request complexity; exhausted credits stop queries. Coverage can be limited for low-traffic or niche domains, and access mirrors purchased datasets, regions, and historical ranges.

Official MCP serverVendor-hosted remote MCPCurrent documented service
Support: Official MCP server
Read scope: Use the hosted MCP to retrieve the web, search, audience, technology, app, referral, and shopper-intelligence data products enabled for the API account; preserve the requested geography, period, granularity, and metric definitions.
Write scope: No state-changing operation is documented in the current first-party MCP tool catalog reviewed on 2026-07-22.
Authentication: Active Similarweb API key supplied to the hosted MCP connection; the same key can be used for the REST and Batch APIs.
Approval boundary: Before a high-volume query, present the requested domains or apps, geography, date range, granularity, metrics, and estimated credit impact when available. A retrieval request should not be represented as a Similarweb account mutation.
Protocol does not erase product boundaries.
Confirm the current tool catalog, plan, region, scopes, rate limits, terms, and write behavior before implementation.

Evidence and dates
First-party references, with publisher and review dates separated
“Publisher updated” is shown only when the page exposes an update date. “BYO-UI reviewed” records when this research checked the reference. A missing publisher date is reported as missing—not replaced with the review date.
