plausible-whenever-mcp
MCP server that provides read access to Plausible Analytics data with natural-language date resolution, enabling users to query analytics like 'yesterday' or 'last week' without needing to know exact date formats.

The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.
list_sitesList all Plausible sites your API key can access, with their timezones. Note: the Sites API is often disabled on self-hosted Plausible — if so, this returns a note telling you to use the configured default site instead. It does NOT affect stats queries.
get_current_timeGet the current date in a site's timezone (today + yesterday as concrete dates). Useful for grounding before analyzing recent data, or to double-check what 'yesterday' resolves to.
get_realtime_visitorsGet the number of people currently on the site (last 5 minutes, real-time).
get_statsGet aggregate stats (single totals) for a site over a period — visitors, pageviews, bounce rate, visit duration, etc. Use for overview/summary questions like 'how did we do yesterday?'.
get_timeseriesGet traffic over time as a series of points (per hour, day, week or month). Use for trends, charts, and 'how did traffic change over the last N days'.
get_breakdownBreak stats down by one or more dimensions — top pages, traffic sources, countries, devices, browsers, UTM tags, etc. Returns ranked rows. Use for 'top pages yesterday', 'where did traffic come from last week', and similar.
compare_periodsCompare aggregate metrics between two periods side by side, with absolute and % deltas. Great for 'yesterday vs the day before', 'this week vs last week', or before/after a deploy. Both periods accept the same friendly keywords as date_range.
queryRun a raw Plausible Stats API v2 query for anything the other tools don't cover (custom property breakdowns, multi-dimension + time series, comparisons, imports, behavioral filters). Friendly date keywords like 'yesterday' and 'last_week' ARE resolved here too (in the site's timezone), so you never …
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
@modelcontextprotocol/sdk has cross-client data leak via shared server/transport instance reuse
Anthropic's MCP TypeScript SDK has a ReDoS vulnerability
Model Context Protocol (MCP) TypeScript SDK does not enable DNS rebinding protection by default
PLAUSIBLE_API_KEYYes Your Plausible Stats API key.PLAUSIBLE_BASE_URL🏠 Self-hosted friendly — works against any Plausible instance via , with a PLAUSIBLE_TIMEZONE override for instances where the Sites API (timezone auto-detect) is disabled.PLAUSIBLE_DEFAULT_SITE_IDNo Default site domain so you can omit site_id on every call.PLAUSIBLE_TIMEZONE🏠 Self-hosted friendly — works against any Plausible instance via PLAUSIBLE_BASE_URL, with a override for instances where the Sites API (timezone auto-detect) is disabled.Tool annotations
No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
8/8 tools missing one or more hints — list_sites (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_current_time (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_realtime_visitors (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +5 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Tool inputs are validated
5/8 tool handlers declare input schemas (63%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool test coverage
Only 0/8 tools referenced in tests (0%)
Write tests that reference each tool by name so every tool has at least one test.
Production dependencies are patched
0 critical, 3 high severity in production deps — @modelcontextprotocol/sdk@1.12.1 (high), @modelcontextprotocol/sdk@1.12.1 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
