Anlyon alternative
3 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 Draw an accurate birth (natal) chart: Sun, Moon and rising sign, every planet with sign, degree and house, the angles and the tightest aspects. Works without a birth time (then no rising sign or houses). Returns a link to the person's sky in 3D on Pluto Garden and guide pages for each placement. Pass the place as the person said it; the server looks it up. Convert the time to 24-hour local time at the birth place.

Description, as the server wrote it Birth chart of a celebrity or famous moment from Pluto Garden's sourced collection (e.g. Billie Eilish, Chappell Roan, Lana Del Rey, Bitcoin, the Moon landing). It only holds birth times the person gave themselves, with the source, so a missing name means no self-reported time is known. Returns the big three, placements, source and page link.

Description, as the server wrote it Today's sky (or any date from 1901 to 2100): the Moon's phase, sign and how much is lit, the next full moon (with its traditional name) and new moon, which planets are retrograde and until when (answers "is Mercury retrograde?"), and the sign of every planet.

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.
- 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
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.

"mcp__pluto-garden__famous_chart"
],
"deny": []
}
}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 pluto-garden. Review it before you use it.

Pin
Keep the decision: fail CI when the tools change, follow every change, or show a badge.
Pin in CI
