Perplexity MCP Integration

Similarweb is available as an official connector in Perplexity. Once connected, Perplexity can access Similarweb's digital intelligence data directly within your conversations.

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

With Similarweb connected, Perplexity draws on 85+ data endpoints covering web analytics, competitive intelligence, audience demographics, app performance, keyword rankings, and more.

Who Has Access

To activate the Similarweb connector, you need an active Similarweb subscription with API access. This includes:

• Business and Enterprise plan subscribers, where API access is included as part of your plan.
• API standalone package subscribers, where full connector access is included.

Data access through the connector mirrors your existing Similarweb subscription. Access is scoped to the specific datasets, regions, and historical ranges included in your plan.

How to Connect

The Similarweb connector is available natively inside Perplexity. No third-party tools or manual server setup required. Follow the steps below to get connected.

Step 1: Open the Connectors menu

1. Open Perplexity in your web browser or launch the Perplexity desktop application.
2. In the left-hand sidebar, click Customize.
3. Select the Connectors tab at the top of the page.

Step 2: Find the Similarweb connector

1. In the Connectors page, use the Search all connectors bar to look for Similarweb.
2. Click the Similarweb result to open the connector details.

Step 3: Authenticate with your Similarweb login

Authentication is seamless and uses your Similarweb login credentials. A browser tab will open. If you're already signed in to Similarweb, just approve the connection. If not, sign in with your Similarweb account first. Once approved, you'll return to Claude and the connector status will show as Connected.

Using Similarweb in your conversations

Once connected, Perplexity can call the Similarweb connector whenever your question requires digital intelligence data. There are two ways to trigger it:

• Mention it directly: Type @Similarweb in your prompt to call the connector explicitly, for example: "@Similarweb compare the traffic of Booking.com and Expedia."
• Ask in context: Even without mentioning Similarweb, Perplexity will detect when your question needs traffic, audience, or competitive data and activate the connector automatically.

Use Cases

The Similarweb connector gives Perplexity access to 75+ data endpoints across web, app, search, and shopper intelligence. Below are examples of what you can ask, organized by dataset.

FAQ

Authentication

The connector won't connect. What should I check? 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.

Do I still need an API key? No. Connecting through Claude uses your Similarweb login. API keys are still used for direct REST and Batch API access.

I connected before this change. Do I need to reconnect? No. Existing connections keep working. You'll see the new sign-in only if you reconnect.

Data & Querying

Why doesn't Perplexity pull Similarweb data for some of my questions?

Perplexity decides when to call the connector based on the context of your question. If the question doesn't clearly require web, app, or competitive intelligence data, it may answer from general knowledge instead. To force the connector, type @Similarweb in your prompt.

Which countries and date ranges are available?

Both depend on your Similarweb subscription. Country coverage and historical depth are aligned with the datasets included in your plan. Refer to your subscription details or contact your account manager for the full scope.

Why are the results different from what I see in the Similarweb platform?

Make sure you're querying the same country, date range, and web source (desktop, mobile, or total) in both places. Slight differences in aggregation methodology between the platform and the API can account for minor variances. For data fidelity questions, contact Similarweb support.

Credits & Cost

Does using the Similarweb connector consume API credits?

Yes. Every query through the connector consumes API credits from your Similarweb subscription, just like a direct API call. The number of credits consumed depends on the volume of data returned. More granular queries (daily data over long ranges, multi-metric requests) consume more credits than simpler lookups.

Where can I monitor my API credit usage?

Your API credit consumption is visible in the Similarweb platform under Account Settings → Data Tools → REST API. This reflects credits consumed across all API channels, including the Perplexity connector.

What happens if I run out of API credits?

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

Is there a way to minimize credit consumption?

Be specific in your prompts. Narrower date ranges, fewer metrics per query, and monthly (rather than daily) granularity will all consume fewer credits.
