Anlyon alternative

8 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.

Tools

Grouped by what each tool does, most consequential first. Open one for its reasons and full description; descriptions are the publisher's own words.

10 tools

Deletes or cancels 1Removes, cancels or revokes something.Claude Code: deny

watch_removeCall this tool to stop tracking one item, by watch id or URL.No findings
Why it is in this group
- The name "watch_remove" says "remove": a word for removing or ending something.
- The description says "cannot be recovered".
- The server marks it destructive (destructiveHint: true).
Description, as the server wrote it
Call this tool to stop tracking one item, by watch id or URL. Its whole price history is deleted and cannot be recovered, so re-adding starts empty. A key matching no watch is refused.
Annotations the server declares
- readOnlyHint: false
- destructiveHint: true
- idempotentHint: false
- openWorldHint: false

Changes things 7Creates or changes something that can be changed back.Claude Code: ask

alerts_pendingAnswer whether anything you watch got cheaper: every watch at or below its target_price, or down 5% or more since the previous observation, with the change %.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.
Description, as the server wrote it
Answer whether anything you watch got cheaper: every watch at or below its target_price, or down 5% or more since the previous observation, with the change %. Reads stored data only: run watch_refresh first.

- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it
Turn Pro on for this connection with key, an MCPL1.<payload>.<signature> issued at checkout for this server or the bundle. Data under your token stays; a wrong or expired key changes nothing. license_status confirms it.
Annotations the server declares
- readOnlyHint: false

- idempotentHint: false
- openWorldHint: false
price_add_manualCall this tool to store a price you read yourself where a shop blocks fetching: it creates the watch if new and returns the amount and the observation count.Can send data outNo findings
Why it is in this group

What it can reach

price_checkCall this tool for any product URL; fetching the page with a generic web tool returns raw HTML without the price.Can send data out1 finding
Why it is in this group
- The description's first verb is "call": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
What it can reach
- outboundThe input takes a URL (input.url): a request to a URL can carry data to whoever runs it.

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 write1: Brings in text someone else can write: web pages, inbound email, messages, issues and comments.; license_status
Can send data out4: Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.; price_add_manual
price_check
price_history
watch_add

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

Findings

Matches of fixed checks, with the text they matched.

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

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 prices-deal. Review it before you use it.
