# See which AI assistants use your MCP server

![The Assistants page of a sample site: 6.6K tool calls, a 2.1% error rate, 749 ms p95 latency and 6.9% empty results, a bar chart of calls by day, and tables of calls by assistant and by tool.](https://highseat.com/assets/assistants-page-D6BKf6P1.webp)

If your site runs its own MCP server, assistants like Claude and ChatGPT call its tools to answer their users. The new Assistants page shows those calls: how many, how many failed, how long they took and how often a tool found nothing. Below that, calls are split by assistant and by tool.

To record them, update the `highseat` package to 0.6.0 or later and call `trackToolCalls(server)` from `highseat/mcp` once, before you register any tool. It works with servers built on the MCP TypeScript SDK v2. Tool arguments, results and the caller's IP address never leave your server.

A call counts as an event on your plan, never as a visitor.

## Visits that assistants send

`mcpLink(url, context)` tags a link a tool returns with `utm_source` and `utm_medium=mcp`. Highseat reads those visits as the AI channel, so the goals and revenue that follow belong to that assistant. The Sources card at the bottom of the page lists them.
