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.

Changes things 3Claude Code: ask
hazard_riskWhat flood, wildfire, and wind risk does this zip code carry?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 What flood, wildfire, and wind risk does this zip code carry? NFIP flood-insurance claims on record (count, payouts, recency, claims per 1,000 housing units), FEMA National Risk Index county scores for flood, wildfire, and wind, and recent significant storm events. Claims are history, not a forecast.
rent_trendWhich way is rent moving in this zip code?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 Which way is rent moving in this zip code? Monthly median-rent history with home values, the direction of movement, and the zip's national and state rank for 3-month rent growth. Updated monthly.
top_marketsWhich US rental markets look strongest right now?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 Which US rental markets look strongest right now? National (or single-state) leaderboard: zips with the highest estimated cap-rate bands among markets with population of 10,000+ and complete rent, vacancy, and home-value data. Cap rates are a modeled band.
Only reads 3Show 3 read-only tools
compare_zipsHow do these zip codes compare as rental markets?No findings
Why it is in this group
- The name "compare_zips" says "compare": a word for reading.
Description, as the server wrote it How do these zip codes compare as rental markets? Side-by-side comparison of 2-6 US zips: rent, cap-rate band (modeled), vacancy, home value, population, renter share, income, employment, with a doorbase.app link for each.
get_zip_marketWhat does the rental market look like in this zip code?No findings
Why it is in this group
- The name "get_zip_market" says "get": a word for reading.
Description, as the server wrote it What does the rental market look like in this zip code? Full profile for a single US zip: rent, cap-rate band (modeled), vacancy, home value, demographics, income, employment, plus the canonical doorbase.app page URL.
search_marketsWhich US zip codes match these rental-market criteria?No findings
Why it is in this group
- The name "search_markets" says "search": a word for reading.
Description, as the server wrote it Which US zip codes match these rental-market criteria? Filters 30,000+ US zip codes by state, cap rate, vacancy, rent, population, home value, and renter share. Returns matching zips with key investor metrics and a doorbase.app link for each. Cap rates are a modeled band; min_cap_rate matches the band's high end.
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.
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.

}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 market-data. 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.
