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.
Description, as the server wrote it Estimates the tax on selling investment real estate outright (gain, section 1245 recapture, unrecaptured 1250 gain at up to 25%, 0/15/20% capital gains stacked on other income, 3.8% NIIT, state tax, cash left) and, when a replacement price is given, the 1031 exchange result: cash and mortgage boot, tax on the boot, gain deferred and replacement basis. 2025 or 2026 federal brackets. Same engine as the 1031.help calculator.

Description, as the server wrote it From the date the relinquished property closed: the 45-day identification deadline, the end of the exchange period (day 180 or the tax return due date if that comes first, by filer type and extension), weekend and federal-holiday flags, days left from today, and the last closing date in that year that keeps the full 180 days. Same math as the 1031.help deadline calculator.

Why it is in this group
- The name "list_dst_offerings" says "list": a word for reading.
Description, as the server wrote it Delaware statutory trust offerings from SEC Form D filings, newest filing first: issuer, location, property type named in the issuer name, offering size, amount reported sold, stated minimum, investors, first sale date, exemption, broker-dealers paid to sell it and the EDGAR link, plus totals for the filtered set. Filter by property type, filing quarter, name or CIK; page with limit and offset. Filings data, not an offer or recommendation.

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 untrusted-input or outbound.
- Reads private data0
- 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.
Remote posture
What anyone on the internet sees at the remote endpoint: an anonymous initialize and tools/list, and the public OAuth metadata.

- 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.
What this check looks forMatched text
https://1031.help/mcp: tools/list returned 3 tools to an anonymous client, including exchange_deadlines (write), estimate_exchange_tax (write)
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.
{
"permissions": {
"allow": [
"mcp__1031-help__list_dst_offerings"

],
"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 1031-help. 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
Fail a build when the tools you reviewed are not the tools the server serves today.
