### MCP Access

The Similarweb Claude connector is powered by our MCP Server and it's available to clients with API access as part of their subscription. This includes:

*   **Business and Enterprise plan subscribers** — API access is included as part of your plan.
    
*   **API standalone package subscribers** — MCP access is included.
    

The data available through the MCP integration mirrors your existing Similarweb subscription. Access is scoped to the specific datasets, regions, and historical ranges included in your plan — no additional data is unlocked via MCP.

### FAQ

#### Authentication & Access

<span style="color:rgb(0, 0, 0);background-color:transparent">**Q: The connector won't connect. What should I check?**</span> <span style="color:rgb(0, 0, 0);background-color:transparent">Confirm your Similarweb subscription includes API access, and that you're signing in with your own Similarweb login. If you share an account with colleagues, you'll each need your own login — contact your account manager.</span>

<span style="color:rgb(0, 0, 0);background-color:transparent">**Q: Do I still need an API key?**</span> <span style="color:rgb(0, 0, 0);background-color:transparent">No. Connecting through Claude uses your Similarweb login. API keys are still used for direct REST and Batch API access.</span>

#### Data & Querying

**Q: What data can I access through the MCP integration?**

The MCP integration provides access to 75+ endpoints, including website traffic and engagement metrics, traffic sources and channel mix, audience demographics, keyword and SEO data, competitive analysis, referral data, mobile app metrics (active users, downloads, sessions, revenue), and Amazon retail intelligence. Data access is governed by your Similarweb subscription.

**Q: What is the most recent data available?**

Most datasets are updated monthly, with data typically available for the prior month by the end of the following month. Some endpoints support daily granularity for more recent periods. Claude will indicate the last updated date in its response when querying Similarweb data.

**Q: Can I query multiple domains or competitors in a single prompt?**

Yes. Claude can run multiple Similarweb queries within a single conversation turn. For example, you can ask it to compare traffic for ten competitors side by side and it will retrieve and synthesize each dataset automatically.

<Divider />

#### Data Credits & Cost

**Q: How does billing work for MCP queries?**

Similarweb MCP queries consume data credits from your data credit allocation, following the same credit structure as the Similarweb REST API. The number of credits consumed depends on the volume of data returned — more granular queries (e.g., daily data over a long time period) or queries covering multiple metrics will consume more credits than simpler lookups.

**Q: Where can I monitor my data credit usage?**

Your credit consumption is visible in the Similarweb platform under **Account Settings → Data Credits Management**. This reflects credits consumed across all tools, including MCP.

**Q: What happens if I run out of data credits?**

Once your credit allocation is exhausted for the billing period, MCP queries will return an error. Contact your Similarweb account manager to discuss increasing your credit limit or upgrading your plan.

#### Troubleshooting

**Q: The connector shows as connected but Claude isn't returning Similarweb data.**

Make sure all Similarweb tools (endpoints) under ‘Tool permissions’ in Claude are not set to ‘Blocked’. You can either set them to ‘Always allow’ or ‘Needs approval’ which will require you to approve access to these tools every time you use the connector. **Q: Claude returned data but it looks different from what I see in the Similarweb platform.**

Ensure you're querying the same country, date range, and web source (desktop vs. mobile vs. total) in both places. Slight differences in aggregation methodology between the platform UI and the API can account for minor variances.
