With Anlyon
1 tool here changes things. Govern it.
- Anlyon lists the tools and adopts none.
- Each tool you adopt gets approvals and receipts.
- Your agent never holds the key.
A tool your agent calls directly is not routed through Anlyon and is not governed by it. anlyon.dev only lists and labels, and these labels are the same either way.
What the Section13Online MCP server can do
The Section13Online MCP server is published by section13online.co.uk, a domain the MCP Registry verified. It has 2 tools. It can create or change data (1 tool: calculate_notice_dates), but cannot delete data. 1 tool only reads.
None of its tools reads private data, brings in text other people write, or sends data out.
None of the fixed checks matched anything in its tool definitions. That is not a safety guarantee.
Its remote endpoint lists its tools without sign-in.

Tools
Grouped by what each tool does, most consequential first. Open one for its reasons and full description; descriptions are the publisher's own words.
2 tools
Changes things 1Claude Code: ask
calculate_notice_datesCalculate the earliest permissible start date for a Section 13 (Form 4A) rent increase for an assured periodic tenancy in England, and the latest date to serve the notice.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 Calculate the earliest permissible start date for a Section 13 (Form 4A) rent increase for an assured periodic tenancy in England, and the latest date to serve the notice. Use when a UK landlord asks about raising rent, Section 13 notice periods, Form 4A timing, or when a rent increase can take effect. England only; general guidance, not legal advice; does not create or serve a notice.
Annotations the server declares

get_eligibility_requirementsList the eligibility requirements for increasing rent with a Section 13 notice (Form 4A) for an assured periodic tenancy in England.No findings
Why it is in this group
- The name "get_eligibility_requirements" says "get": a word for reading.
Description, as the server wrote it List the eligibility requirements for increasing rent with a Section 13 notice (Form 4A) for an assured periodic tenancy in England. Use when someone asks whether they can use Section 13, what the rules for a rent increase are, or what Form 4A is. England only; general guidance, not legal advice.

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

The endpoint served tools/list without credentials, and the list has 1 tool that changes things (1 write). Whether a call also works without credentials was not tested: tools are never called.
What this check looks forMatched text
https://section13online.co.uk/api/mcp: tools/list returned 2 tools to an anonymous client, including calculate_notice_dates (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__section13-online__get_eligibility_requirements"
],
"ask": [
"mcp__section13-online__calculate_notice_dates"
],
"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 section13-online. 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.
