Query site stats, realtime visitors, breakdowns and goals from Plausible Analytics. For website owners and marketers who track their sites with Plausible Analytics. Hosted by usefulapi — connect from Claude, ChatGPT, 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": {
"plausible-analytics": {
"url": "https://plausible-analytics.usefulapi.io/mcp"
}
}
}Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"plausible-analytics": {
"type": "http",
"url": "https://plausible-analytics.usefulapi.io/mcp"
}
}
}No Add custom MCP server option? It depends on your account or workspace settings: see OpenAI's guide.
Run these commands. The second one opens the login page:
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 AI reads totals for the metrics you name over two date ranges and compares them, for example this month and last month.
plausible_aggregate plausible_query_stats
The AI breaks metrics down by page, for example by visitors, and lists the top ones for the date range you choose.
plausible_breakdown plausible_query_stats
The AI breaks metrics down by source and by other properties. You see which sources bring the most visitors.
plausible_breakdown plausible_query_stats
The AI reads metrics grouped by a time interval and describes the trend, with peaks and dips.
plausible_timeseries
The AI reads the number of current visitors, active in the last 5 minutes, for one of your sites.
plausible_realtime_visitors plausible_list_sites
The login page asks for your Plausible API key.
Create one in Plausible → Account Settings → API keys. Your API key is used only to call the API on your behalf and to derive a private account id; 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 Plausible API key. 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.
Turn on the Plausible connector, then ask in plain words. The AI picks the tools.
| Tool | Type | What it does |
|---|---|---|
plausible_query_stats | read | Query stats The full-power Stats API query. Compute metrics over a date range, optionally grouped by dimensions and narrowed by filters, with ordering, includes, and pagination. Plausible: POST /api/v2/query. |
plausible_aggregate | read | Aggregate totals Convenience: aggregate totals for the given metrics over a date range (no group-by). Plausible: POST /api/v2/query with no dimensions. |
plausible_timeseries | read | Timeseries Convenience: metrics over time, grouped by a time interval. Plausible: POST /api/v2/query with dimensions=[interval]. |
plausible_breakdown | read | Breakdown by property Convenience: break metrics down by a single property (dimension), e.g. visit:source or event:page. Plausible: POST /api/v2/query with dimensions=[property]. |
plausible_realtime_visitors | read | Realtime visitors Get the number of current visitors on a site (active in the last 5 minutes). Returns a single integer. Plausible: GET /api/v1/stats/realtime/visitors. |
plausible_list_sites | read | List sites List the sites the API key can access (domain + timezone), with cursor pagination. Requires an enterprise plan. Plausible: GET /api/v1/sites. |
plausible_get_site | read | Get site Get a single site by its domain (timezone, etc.). Requires an enterprise plan. Plausible: GET /api/v1/sites/{site_id}. |
plausible_list_goals | read | List goals List the goals (conversions) configured for a site. Requires an enterprise plan. Plausible: GET /api/v1/sites/goals. |
plausible_analytics_usage_status | Usage status (free-tier meter) Report the caller's current usage: the plan, calls used this month, the limit of the plan (the free monthly cap or the Pro fair use limit), remaining, and whether the limit is reached. Read-only; does not count against the meter. | |
plausible_analytics_request_feature | Request a missing feature Tell usefulapi that the user needs something the Plausible 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. | |
plausible_analytics_upgrade | Upgrade to Pro (unlimited*) Get Pro: unlimited tool calls (fair use limit: 10,000 a month) on Plausible (the free tier caps monthly usage). Plans: "monthly" — $9/month; "yearly" — $90/year (2 months free). Cancel any time: Pro then runs to the end of the paid period, so it also suits a one-time job. *A fair use limit applies. For heavy use (near Pro's limit): "plus" or "plus_yearly" — Pro+, $39/month or $390/year, unlimited tool calls (fair use limit: 100,000 a month); an existing Pro subscription changes to Pro+ in place (needs confirm: true; the price difference for the rest of the period is charged at once). Otherwise returns a short link to open in your browser (it opens Stripe Checkout); after payment the account upgrades automatically. Does not count against the meter. | |
plausible_analytics_cancel_subscription | Cancel the Pro subscription Cancel the caller's Plausible Pro subscription at the end of the paid period (no refund for the current period; Pro continues until then, then the free tier applies). Requires confirm: true. Run plausible_analytics_upgrade later to undo the cancel before the period ends. Does not count against the meter. |
| Plan | Price | Limit |
|---|---|---|
| Free | $0 | 50 tool calls / month |
| Pro | $9/mo · $90/yr | Unlimited* |
*Pro fair use limit: 10,000 tool calls a month on this server. For more, write to [email protected].
Pro covers this Plausible server only. Subscribe with plausible_analytics_upgrade (it returns a Stripe Checkout link). Cancel any time with plausible_analytics_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running plausible_analytics_upgrade before then undoes the cancel. Or write to [email protected].
Compare visitors between two periods. Find your top pages. See where your traffic comes from. Check how traffic changed over time. See how many visitors are on your site now. See what you can do for the details.
No. usefulapi is an independent service. It is not affiliated with or endorsed by Plausible. The server calls the Plausible API with your own Plausible access, so it sees only the data that your account can see.
Yes. In Claude, add this server's URL as a custom connector. In ChatGPT, add it as a custom MCP server in Plugins. Then log in once. Cursor, VS Code, Claude Code and Codex work too. See the setup steps.
The login page asks for your Plausible API key. 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 Plausible API key. 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 Plausible 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 Plausible.
All 8 Plausible tools are marked read-only.
The Free plan gives 50 tool calls / month. Pro costs $9/mo or $90/yr, with unlimited tool calls (fair use limit: 10,000 tool calls a month), for this Plausible server only. Cancel any time: Pro then runs to the end of the paid period. Run plausible_analytics_usage_status to see how many calls you used.
Ask the AI to run plausible_analytics_upgrade: it returns a Stripe Checkout link. To cancel, run plausible_analytics_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 plausible_analytics_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, ChatGPT, Codex, 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.
