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.

Changes things 2Claude Code: ask
convert-unix-timestamp-to-dateUnix timestamps to UTC dates in ISO 8601.1 finding
Why it is in this group
- The name "convert-unix-timestamp-to-date" says "convert": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Findings
- Warn
The server marks "convert-unix-timestamp-to-date" read-only (readOnlyHint: true), and its own name, description or input give the class "write".
What this check looks forMatched text
annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "convert-unix-timestamp-to-date" says "convert": a word for a change.
Description, as the server wrote it Unix timestamps to UTC dates in ISO 8601. text holds one or more timestamps, one per line: whole seconds or milliseconds, where a magnitude of 100000000000 or more is milliseconds. The answer is a CSV of input, unit and date. It refuses empty text, more than 1,048,576 bytes or 10,000 lines, and any line that is not digits with an optional leading minus inside the years 0001 to 9999. Free. The answer is the JSON envelope of https://foundry.dap.solutions/api/convert-unix-timestamp-to-date, byte for byte, with the artifact hash that answered.

decode-base64-to-textBase64 to UTF-8 text.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 Base64 to UTF-8 text. text holds standard base64: A to Z, a to z, 0 to 9, + and /, padding optional; white space is ignored. It refuses empty text, more than 1,048,576 bytes, the URL-safe alphabet, a length or padding that cannot be base64, and bytes that are not valid UTF-8. Free. The answer is the JSON envelope of https://foundry.dap.solutions/api/decode-base64-to-text, byte for byte, with the artifact hash that answered. Full rules: https://foundry.dap.solutions/hub.md

compute-day-count-to-settlementSettlement date on the Payments Canada holiday calendar, and the accrual fraction under ACT/360, ACT/365F, 30/360, 30E/360 or ACT/ACT-ISDA.Reads private dataNo findings
Why it is in this group
- The name "compute-day-count-to-settlement" says "count": a word for reading.
What it can reach
- private-dataThe description's first sentence says "calendar": it reads calendars.
- private-dataThe input names a calendar (input.calendar), and the tool reads: it reads calendars.
Description, as the server wrote it Settlement date on the Payments Canada holiday calendar, and the accrual fraction under ACT/360, ACT/365F, 30/360, 30E/360 or ACT/ACT-ISDA. Send all seven inputs, including acknowledge no-ruling-v1 and a freshness_tolerance in whole days written P<n>D. It refuses rather than guesses: a missing acknowledgement or tolerance, a tolerance over the ratified ceiling, calendar data older than your tolerance, a trade date outside the calendar's coverage or not a business day, and any missing, unknown or malformed input. Costs $0.01 in USDC on Base per computed answer, under x402; a refusal is not charged.

diff-two-line-listsCompare two lists of lines.No findings
Why it is in this group
- The name "diff-two-line-lists" says "diff": a word for reading.
Description, as the server wrote it Compare two lists of lines. text holds a line ---A---, then list A, then a line ---B---, then list B. The answer is a CSV of each distinct line, matched exactly as sent, marked only_a, only_b or both. It refuses empty text, more than 1,048,576 bytes or 50,000 lines, and a text without the two markers in that order. Free. The answer is the JSON envelope of https://foundry.dap.solutions/api/diff-two-line-lists, byte for byte, with the artifact hash that answered. Full rules: https://foundry.dap.solutions/hub.md

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 untrusted-input or outbound.
- Reads private data1
- Reads files, mail, messages, databases, secrets, calendars or repositories.
- Reads text others write0
- 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.
The server marks "convert-unix-timestamp-to-date" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

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 foundry. Review it before you use it.
