What users hate about ANY iOS/Android app: clustered complaints, evidence, trends. No key needed.

7 tools: 2 change things and 5 only read.

Anlyon alternative

2 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.

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.
What it can reach
- untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
Description, as the server wrote it
THE core tool: fetch recent reviews of any iOS/Android app, keep the negative ones, and cluster them into ranked pain points (title, sharePercent, severity 1-5, verbatim evidence quotes). Ideal for competitive research and product discovery. Cached 7 days (instant on repeat); a COLD server-side analysis takes 30-120s. If the result has "mode":"agent", it contains prepared negative reviews and "instructions" — do the clustering yourself and present it to the user.

Description, as the server wrote it
Continuous competitor monitoring (paid plans: Starter 2 apps weekly, Pro 15 apps daily). Manage the watchlist and the alert destination; digests of NEW 1-2★ reviews and NEW/RISING pain points are pushed to a Slack / Discord / any https webhook. action: list | add | remove | set_webhook | test.

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.

Exfil surface

Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.

No private-data, untrusted-input, outbound path in this server alone: no tool is tagged private-data.

Reads private data0: Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write7: Brings in text someone else can write: web pages, inbound email, messages, issues and comments.; get_app_details
get_app_reviews
get_pain_trend
get_version_history
mine_app_pain_points
search_apps
watch_competitors
Can send data out1: Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.; watch_competitors

Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.

Remote posture

What anyone on the internet sees at the remote endpoint: an anonymous initialize and tools/list, and the public OAuth metadata.

Tools listed without sign-in

Looked at Oct 23, 2026, 15:19 UTC, unchanged since Oct 23, 2026. No credentials were sent and no tool was called. What is looked at.

Reachable: yes

WarnThe whole server
The endpoint served tools/list without credentials, and the list has 2 tools that change things (2 write). Whether a call also works without credentials was not tested: tools are never called.
Matched text
https://app-pain-api.quiet-delta.workers.dev/mcp: tools/list returned 7 tools to an anonymous client, including mine_app_pain_points (write), watch_competitors (write)
What this check looks for

Findings

Matches of fixed checks, with the text they matched.

No check matched anything in these tool definitions. That is not a safety guarantee.

History

Changes to its tool definitions and to its remote endpoint, newest first.

No change seen yet. Its tools are rescanned every day, and a remote endpoint is looked at once a week.

Claude Code permissions

Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.

}

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. A read that can send data out (it takes a URL, say) asks first too. It assumes the server is installed as app-pain-api. Review it before you use it.
