Fathom Analytics MCP server

What the model can do

Fathom Analytics: visits, unique visitors, pageviews, visit length and bounce rate for a period against the one before, top pages and sources, breakdowns by country, device, browser, referrer or UTM, trends by hour, day or month, event conversions, and who is on the site right now; marks milestones on a site's charts, sets an event's currency, renames a site or changes its timezone or public sharing, and creates or deletes a site.

Acts, when you ask

These change something in Fathom Analytics. The model is told to use them only when you ask for exactly that, and each one is granted by name: per team on a shared connection, by the owner on a personal one.

• fathom_create_milestoneMarks a milestone (a name of up to 30 characters on a date) on a site's Fathom charts, seen by everyone who views the dashboard.
• fathom_update_milestoneRenames or moves a milestone on a site's Fathom charts.
• fathom_delete_milestoneDeletes a milestone from a site's Fathom charts.
• fathom_set_event_currencySets the currency a site's event values are reported in (dollar, pound, euro, yuan, peso, shekel, yen, won, hryvnia, franc, rupee, integer, none…
• fathom_update_siteRenames a Fathom site, changes its reporting timezone, or turns its public share link on…
• fathom_create_siteCreates a new site in the Fathom account (sharing off), returning its id for the tracking code.
• fathom_delete_siteDeletes a Fathom site and every pageview and event recorded for it.

Connect it

First connect Fathom Analytics on Dashboard → Connections, then add Memtro to your client once. The Fathom Analytics tools appear alongside the tools of everything else you have connected; nothing is configured per connector.

Who may use it

The key identifies the person, and the server offers that person the tools they may use everywhere else in Memtro. A shared Fathom Analytics connection is used by the teams an administrator granted it to, tool by tool, on the Permissions page; a personal connection is used by its owner alone, and its tools that act stay off until the owner allows them. See Teams and permissions and Connectors.

Questions

Is this an official Fathom Analytics MCP server?

No. It is Memtro's MCP server with Memtro's Fathom Analytics connector behind it: the connector reads Fathom Analytics through its API with the credentials you connect on Dashboard → Connections, and Fathom Analytics publishes nothing here. The same endpoint carries every other system you connect and Memtro's memory tools.

What does it cost?

Nothing on top of Memtro. One price per organisation by its number of users, from $50 a month for up to 10 users after a 7-day free trial, with every connector, the MCP server, jobs and memory included. You bring your own model keys.

Can it change anything in Fathom Analytics?

Only when you ask, and only what it has been granted: add, rename, move or delete a milestone on a site's charts; set the currency an event's value is reported in; rename a site, change its reporting timezone, or turn its public share link on or off; create a site, or delete one and all its data permanently. Every other tool reads, searches or lists. An administrator grants each acting tool by name per team, and a personal connection acts only after its owner allows it.

Which clients work?

Any MCP client that speaks Streamable HTTP: Claude Code, Cursor, Claude Desktop, OpenCode, Codex, Zed, Windsurf, Cline and the Anthropic and OpenAI SDKs. There is no local process to run; the server is remote and authenticated with your key.
