Tool names and descriptions exactly as the server reported them on Nov 9, 2026. The maker wrote them, not us; we show them as plain text.
fathom_get_tokenThe connected API token's name, permissions (abilities: "*" = Admin, "all-sites-readonly", or per-site read: / manage: ) and timestamps. The secret value is never returned. Good first call to know which tools will work. GET /token.
fathom_get_accountThe Fathom account that owns the API token: id, name and email. Needs an Admin token (the * scope). GET /account.
fathom_list_sitesList the sites the token can read (id, name, sharing, timezone, created_at), oldest first. The site id is what every report tool takes. Needs an Admin or all-sites read-only token; a token scoped to a single site cannot list sites, so use fathom_get_site with that site id instead
fathom_get_siteOne site: id, name, sharing (none/private/public), timezone and created_at. GET /sites/{site_id}.
fathom_list_eventsList a site's events (conversions/goals): every event name the site has tracked plus events with a currency set, sorted by name. Identify events by name (use it as event_name in fathom_get_aggregation); the id is only a paging cursor. Paged: pass next.starting_after. GET /sites/{
fathom_list_milestonesList a site's milestones (dated annotations on reports, such as a redesign launch or a campaign start), oldest first. Paged: pass next.starting_after. GET /sites/{site_id}/milestones.
fathom_get_milestoneOne milestone: id, name, milestone_date, created_at, updated_at. GET /sites/{site_id}/milestones/{milestone_id}.
fathom_get_aggregationFathom's custom report (the dashboard's numbers): aggregate pageviews or one event over a date range, optionally grouped by date and/or fields and filtered. Pageviews: aggregates visits (unique site visits), uniques (unique page visits), pageviews, avg_duration (seconds), bounce_
fathom_get_current_visitorsLive visitors on a site right now: the total, and with detailed true the top 150 pages (hostname, pathname, total) and top 150 referrers. GET /current_visitors.
fathom_create_siteCreate a new site in the Fathom account (returns its id, used in the tracking code). Needs an Admin token. Sharing private needs share_password; multi_domain true needs multi_domain_option. POST /sites.
fathom_update_siteChange a site's name, sharing, timezone or multi-domain setting (send only what changes). Changing the timezone changes how reports are bucketed. Needs a manage token for the site. POST /sites/{site_id}.
fathom_set_event_currencySet the currency of an event's value by event name (works before the event is first tracked). Needs a manage token for the site. POST /sites/{site_id}/events/currency.
fathom_clear_event_currencyRemove the currency set for an event, so it uses the site's default again. The event and its completion data stay. Needs a manage token for the site. DELETE /sites/{site_id}/events?name=.
fathom_create_milestoneAdd a milestone (a dated annotation shown on the site's reports, e.g. a launch or campaign start). Needs a manage token for the site. POST /sites/{site_id}/milestones.
fathom_update_milestoneRename or re-date a milestone (both name and milestone_date are required). Needs a manage token for the site. POST /sites/{site_id}/milestones/{milestone_id}.
fathom_delete_milestonePermanently delete a milestone (only the annotation; traffic data is not touched). Cannot be undone. Needs a manage token for the site. DELETE /sites/{site_id}/milestones/{milestone_id}.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 4 of 4 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
The GitHub repo last changed yesterday, and the latest version (1.26.0) reached the registry yesterday.
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT on the web (full MCP on Business and above; Pro read-only).
