Dashboard Analytics Subscriptions

Each tier includes everything in the tier before it. Telemetry for the Action and Predictive tabs is captured on every request no matter which tier you are on, so upgrading fills those tabs with your existing history. Full walkthrough in the analytics docs.

Common questions

What counts as an MCP call?

Each tool invocation from an MCP client (like Cursor or Claude Desktop) counts as one call. Search, code extraction, Q&A — each is one call.

How do monthly MCP requests work?

Plans renew every 30 days with their included request allowance. Overage usage can continue at $0.10/request if you enable usage-based fees and set a monthly budget cap.

What if I upgrade plans mid-cycle?

Requests are now subscription-based, so upgrades change your active plan for the next billing cycle and renew automatically every 30 days unless canceled.

Are extra sources permanent?

No. The first 2 sources per server are included for free. After that, each additional source is $3.

How many MCP servers can I create?

Every account can create up to 3 MCP servers for free. Each server includes 2 sources. Need more than 3 servers? Contact zair@appatools.com for an Enterprise plan.

What happens when I hit my call limit?

MCP calls will return a friendly limit message unless usage-based fees are enabled. Your servers stay online and your data is never deleted.

What is the highest request plan?

The highest MCP plan includes 1,000 requests per month. For higher usage, enable usage-based fees to keep serving requests over your included plan amount.

Is this a subscription?

Yes. Paid plans are subscriptions that automatically renew every 30 days unless canceled.

How large can my sources be?

Source size is measured in indexed chunks — the small passages we split your content into so an AI agent can retrieve exactly the right part. The allowance is per MCP server and cumulative: all of that server's sources share it. Free includes up to 500K chunks per server, and each paid request plan raises it, up to 3M on the highest plan.

What happens if a source is too large for my plan?

Indexing stops at your allowance instead of failing. Everything already indexed stays queryable and your MCP server keeps working. You can upgrade for a larger allowance, or remove another source from that server to make room.
