Findings

Matches of fixed checks, with the text they matched.

    The server marks "mixpanel_jql" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

    Matched text

    annotations: {"readOnlyHint":true}; The description's first verb is "run": a word for a change.

Changes things 2Claude Code: ask
  • mixpanel_jqlRun a custom JQL (JavaScript Query Language) script for arbitrary analysis.1 finding

    Why it is in this group

    • The description's first verb is "run": a word for a change.
    • The input takes a statement or command to run (input.script), which can change anything it can reach.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

    • Warn

      The server marks "mixpanel_jql" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

      Matched text

      annotations: {"readOnlyHint":true}; The description's first verb is "run": a word for a change.

      What this check looks for
    Description, as the server wrote it
    Run a custom JQL (JavaScript Query Language) script for arbitrary analysis. Power-user escape hatch. Script must define main(). Query API: POST /jql. (Upstream maintenance mode; 2-min timeout, 5GB/query limit.)

    Annotations the server declares

    • title: Run a JQL query
    • readOnlyHint: true
  • mixpanel_retentionCohort retention: of users who did `born_event`, how many came back and did `event` over subsequent intervals.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Cohort retention: of users who did `born_event`, how many came back and did `event` over subsequent intervals. Query API: GET /retention.

    Annotations the server declares

    • title: Retention report
    • readOnlyHint: true

  • mixpanel_list_funnelsGet the funnel_id and name of every saved funnel in the project.No findings

    Why it is in this group

    • The name "mixpanel_list_funnels" says "list": a word for reading.
    Description, as the server wrote it
    Get the funnel_id and name of every saved funnel in the project. Query API: GET /funnels/list.

    Annotations the server declares

    • title: List saved funnels
    • readOnlyHint: true
  • mixpanel_query_funnelGet conversion data for a saved funnel (use mixpanel_list_funnels to find funnel_id).No findings

    Why it is in this group

    • The name "mixpanel_query_funnel" says "query": a word for reading.
    Description, as the server wrote it
    Get conversion data for a saved funnel (use mixpanel_list_funnels to find funnel_id). Query API: GET /funnels.

    Annotations the server declares

    • title: Query a saved funnel
    • readOnlyHint: true
  • mixpanel_query_insightsFetch the computed data behind a saved Insights report by bookmark_id (the report id in the board URL).No findings

    Why it is in this group

    • The name "mixpanel_query_insights" says "query": a word for reading.
    Description, as the server wrote it
    Fetch the computed data behind a saved Insights report by bookmark_id (the report id in the board URL). Mixpanel's recommended, non-deprecated path for programmatic reporting. Query API: GET /insights.

    Annotations the server declares

    • title: Query a saved Insights report
    • readOnlyHint: true
  • mixpanel_segmentationCount/segment/filter a single event over a date range.No findings

    Why it is in this group

    • The description's first verb is "count": a word for reading.
    Description, as the server wrote it
    Count/segment/filter a single event over a date range. e.g. 'Signed up' by country last week. Params `on`/`where` use Mixpanel segmentation expressions like properties["$country_code"]. Query API: GET /segmentation. (Upstream maintenance mode — for saved reports prefer mixpanel_query_insights.)

    Annotations the server declares

    • title: Segment an event
    • readOnlyHint: true
  • mixpanel_top_eventsList today's top events with counts and % change vs yesterday.No findings

    Why it is in this group

    • The description's first verb is "list": a word for reading.
    Description, as the server wrote it
    List today's top events with counts and % change vs yesterday. Good first call to discover what events a project tracks. Query API: GET /events/top.

    Annotations the server declares

    • title: Top events (today)
    • readOnlyHint: true

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
