6 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.

keyword_top_pinsThe best-performing pins ranking for a keyword, by saves, with their titles, links and save counts — what is winning that search right now.1 finding
Why it is in this group
- The name "keyword_top_pins" says "pin": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

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

  What this check looks for
Description, as the server wrote it
The best-performing pins ranking for a keyword, by saves, with their titles, links and save counts — what is winning that search right now. est_clicks is an ESTIMATE derived from saves (Pinterest does not publish clicks or impressions for pins you do not own); pins_analysed, saves and competition are measured from the pins we crawled. Needs the Pro plan or above.

my_quotaYour PinPinterest plan, how many lookups you have used this month and when they reset.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
Your PinPinterest plan, how many lookups you have used this month and when they reset. Free — uses no lookup.

  What this check looks for
Description, as the server wrote it
The best-performing pins across a whole niche (use list_niches for the slugs), sorted and paged. Pass next_cursor back as cursor for the next page. There is no impressions sort: Pinterest does not publish impressions for pins you do not own, so we do not invent them. Needs the Pro plan or above.

related_keywordsKeywords that appear on the same ranking pins as yours, strongest overlap first — the ones worth targeting next.No findings
Why it is in this group

- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
Keywords that appear on the same ranking pins as yours, strongest overlap first — the ones worth targeting next. Each comes with how many pins it shares and its own competition. Needs the Starter plan or above.
Annotations the server declares
- readOnlyHint: true
- openWorldHint: false
request_keywordsAsk PinPinterest to crawl Pinterest for keywords it has no data for yet — offer this after keyword_lookup answers tracked:false, especially for a list.Reads text others writeNo findings
Why it is in this group
- The name "request_keywords" says "request": a word for a change.
What it can reach
- untrusted-inputThe description's first sentence says "crawl": it reads web pages, which anyone can write.
Description, as the server wrote it
Ask PinPinterest to crawl Pinterest for keywords it has no data for yet — offer this after keyword_lookup answers tracked:false, especially for a list. Pass up to 25 terms; each comes back with a request_id and a status (queued, crawling, ready, failed). Crawls usually land within 10–40 minutes and the person gets ONE e-mail when they are in; asking keyword_lookup again after crawl.retry_after_minutes returns the data. Asking twice for the same term is the same request. Uses no lookup; up to 25 new keywords a day per account. Needs the Starter plan or above.

keyword_lookupPinterest data for one keyword: how many ranking pins we analysed, their average and total saves, competition (low/medium/high) and an opportunity score, plus its niche.No findings
Why it is in this group
- The name "keyword_lookup" says "lookup": a word for reading.
Description, as the server wrote it
Pinterest data for one keyword: how many ranking pins we analysed, their average and total saves, competition (low/medium/high) and an opportunity score, plus its niche. est_clicks is an ESTIMATE derived from saves (Pinterest does not publish clicks or impressions for pins you do not own); pins_analysed, saves and competition are measured from the pins we crawled. A keyword we do not hold returns tracked:false with close suggestions and does not use a lookup. Its crawl field says what happens next: on a paid plan we have already started crawling it (crawl.status queued or crawling) — tell the person to ask again in crawl.retry_after_minutes, or that we e-mail them when it is in. When several keywords come back tracked:false, offer request_keywords to queue them all in one call.

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 or outbound.

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.; request_keywords
Can send data out0: Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.

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

Findings

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 keywords. Review it before you use it.
