Query Fathom Analytics sites, stats, current visitors and events, and manage sites and events. Hosted by usefulapi — connect from Claude, Cursor, or any MCP client.
Team and Enterprise: an Owner adds the connector for the organization first.
Run this command, then run /mcp in Claude Code to log in:
Add to Cursor or add this to ~/.cursor/mcp.json:
{
"mcpServers": {
"fathom-analytics": {
"url": "https://fathom-analytics.usefulapi.io/mcp"
}
}
}Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"fathom-analytics": {
"type": "http",
"url": "https://fathom-analytics.usefulapi.io/mcp"
}
}
}Other MCP clients (Windsurf, Cline, Zed and more): add the URL as a remote MCP server (Streamable HTTP). The client then opens the login page in your browser. Do not add an Authorization header: see Before you connect.
The login page asks for your Fathom Analytics API token.
Create a token at app.usefathom.com/api → Create new. A read only (all sites) token is enough for reports; writes need Admin or site-manage access. Every API request counts towards your monthly pageviews. Your token is used only to call the Fathom API on your behalf; it is never shown to anyone.
Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your Fathom Analytics API token. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.
| Tool | Type | What it does |
|---|---|---|
fathom_get_token | read | Get the API token's permissions The connected API token's name, permissions (abilities: "*" = Admin, "all-sites-readonly", or per-site read:<id> / manage:<id>) and timestamps. The secret value is never returned. Good first call to know which tools will work. GET /token. |
fathom_get_account | read | Get the account The Fathom account that owns the API token: id, name and email. Needs an Admin token (the * scope). GET /account. |
fathom_list_sites | read | List sites List 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. Paged: pass next.starting_after. GET /sites. |
fathom_get_site | read | Get a site One site: id, name, sharing (none/private/public), timezone and created_at. GET /sites/{site_id}. |
fathom_list_events | read | List a site's events List 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/{site_id}/events. |
fathom_list_milestones | read | List a site's milestones List 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_milestone | read | Get a milestone One milestone: id, name, milestone_date, created_at, updated_at. GET /sites/{site_id}/milestones/{milestone_id}. |
fathom_get_aggregation | read | Run a traffic or event report Fathom'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_rate. Events (entity event + event_name): conversions, unique_conversions, value (in cents). Examples: top pages = field_grouping [pathname], sort_by pageviews:desc; traffic sources = [referrer_source] or [referrer_hostname]; AI referrals = [ai_source]; daily trend = date_grouping day. All numbers come back as strings. Dates are in the site's timezone; hour grouping only for ranges up to 7 days. Grouped reports return at most 500 rows unless limit is set (max 1000, no paging), so narrow with filters or dates. Data before March 2021 cannot be grouped/filtered. GET /aggregations. |
fathom_get_current_visitors | read | Get current visitors Live 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_site | write | Create a site Create 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_site | write | Update a site Change 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_currency | write | Set an event's currency Set 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_currency | write | Clear an event's currency Remove 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_milestone | write | Create a milestone Add 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_milestone | write | Update a milestone Rename 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_milestone | write | Delete a milestone Permanently 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}. |
fathom_usage_status | Usage status (free-tier meter) Report the caller's current free-tier usage this month: calls used, monthly limit, remaining, and whether the cap is reached. Read-only; does not count against the meter. | |
fathom_request_feature | Request a missing feature Tell usefulapi that the user needs something the Fathom Analytics tools cannot do yet (a missing tool, field or filter). Call it only when the user asks for something none of the tools can do, and tell the user that you send the request. Do not call it for errors or for normal requests. Do not include personal data, credentials or customer records. Stored with the product name and the client type (for example Claude or Cursor), without the user's account. At most 5 requests per day. Does not count against the meter. | |
fathom_upgrade | Upgrade to Pro (unlimited) Subscribe to the Pro plan for UNLIMITED Fathom Analytics tool calls (the free tier caps monthly usage). Choose monthly ($9/month) or yearly ($90/year — 2 months free) billing. Returns a Stripe Checkout link to open in your browser; after payment your account upgrades automatically. Does not count against the meter. | |
fathom_cancel_subscription | Cancel the Pro subscription Cancel the caller's Fathom Analytics Pro subscription at the end of the paid period (no refund for the current period; unlimited calls continue until then, then the free tier applies). Requires confirm: true. Run fathom_upgrade later to undo the cancel before the period ends. Does not count against the meter. |
| Plan | Price | Limit |
|---|---|---|
| Free | $0 | 100 tool calls / month |
| Proper user | $9/mo · $90/yr | Unlimited |
Pro covers this Fathom Analytics server only. Subscribe with fathom_upgrade (it returns a Stripe Checkout link). Cancel any time with fathom_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running fathom_upgrade before then undoes the cancel. Or write to [email protected].
No. usefulapi is an independent service. It is not affiliated with or endorsed by Fathom Analytics. The server calls the Fathom Analytics API with your own Fathom Analytics access, so it sees only the data that your account can see.
The login page asks for your Fathom Analytics API token. See Before you connect for where to find it.
No. Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your Fathom Analytics API token. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.
The login stores them encrypted in the authorization grant of your connection. The server uses them to call the Fathom Analytics API for you and to derive a private account id for usage metering. usefulapi does not show them on any page or in any reply. To stop all access, remove the connector and change or delete these credentials in Fathom Analytics.
Yes, if you approve it. 7 of the 16 Fathom Analytics tools can create or change data. The other 9 are marked read-only. Most MCP clients ask you to approve a tool call before it runs.
The Free plan gives 100 tool calls / month. Pro costs $9/mo or $90/yr, with unlimited tool calls, for this Fathom Analytics server only. Run fathom_usage_status to see how many calls you used.
Ask the AI to run fathom_upgrade: it returns a Stripe Checkout link. To cancel, run fathom_cancel_subscription. Pro continues to the end of the paid period.
Tell the AI what you wanted to do. It can send the request with fathom_request_feature. We store the text with the server name, the type of AI client and the tool you tried, not with your account, and read every request when we plan new tools. You can send up to 5 requests per day.
Any client that supports remote MCP servers (Streamable HTTP) with OAuth login: Claude (web and desktop), Claude Code, Cursor, VS Code, Windsurf and others.
This is a Model Context Protocol endpoint — meant to be connected from an AI client, not opened in a browser. An invalid_token response at the URL is the auth gate working as designed; clients authenticate automatically.
