Manus Integration

Similarweb is now available as an official connector on the Manus app marketplace. Once connected, Manus can access Similarweb's digital intelligence data directly within your AI agent conversations.

Ask questions in plain language and get answers backed by real traffic, keyword, referral, and page-level data, no switching tabs, no manual lookups. The connector handles everything behind the scenes; all you do is authenticate once and start asking.

Access Paths

The Similarweb integration in Manus is available through two paths, designed for different users:

• Integrated Similarweb experience — Available to all Manus Pro users out of the box. No Similarweb account required. Usage is charged through Manus credits.
• Similarweb MCP connector — Available to existing Similarweb customers with API access as part of their subscription. Connect your own API key to use the metrics included in your Similarweb plan.

This guide covers setup for the MCP connector. For information on the integrated experience, see the Manus documentation.

MCP Access

The Similarweb Manus 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

Q: I entered my API key but the connector won't authenticate. What should I check?

Verify that your API key is copied correctly and that it's active in the Similarweb platform. Confirm that your Similarweb subscription includes API access. If the issue persists, contact your account admin or reach out to Similarweb support.

Q: Can I use a Batch API key to activate the MCP connector?

Yes, your MCP connector will work with any API key as long as it's active.

Q: My plan includes Similarweb access but I don't see an API key. Why?

API access is included with Business and Enterprise plans and the API standalone package. If you can't generate your own key, reach out to your account manager to generate one for you.

Q: Do I need a Similarweb subscription to use Similarweb data in Manus?

No. Manus Pro users can access the integrated Similarweb data experience using Manus credits, without a Similarweb subscription. The MCP connector is the path for existing Similarweb customers who want to use their own API access.

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 (incoming and outgoing), landing pages, popular pages, 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. Manus 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. Manus can run multiple Similarweb queries within a single conversation. For example, you can ask it to compare traffic for ten competitors side by side and it will retrieve and synthesize each dataset automatically.

Data Credits & Cost

Q: How does billing work for MCP queries?

Similarweb MCP queries consume data credits from your API 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 API credit usage?

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

Q: What happens if I run out of API credits?

Once your API 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 Manus isn't returning Similarweb data.

Check that the Similarweb connector is enabled in your Manus session. If you've authenticated successfully but queries aren't being routed, try starting a new conversation and asking a more specific question that mentions a domain or metric.

Q: Manus 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. For data fidelity questions, contact Similarweb support.
