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.

calculate_paycheckEstimate 2026 take-home pay for one paycheck in California, New York, Illinois, Texas, or Florida.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 Estimate 2026 take-home pay for one paycheck in California, New York, Illinois, Texas, or Florida. Federal income tax, Social Security, Medicare, and that state's withholding use the same figures as auracalcs.com. Returns the paycheck lines, a link to the matching page, the publications and the date they were checked, and a disclaimer. Estimate only.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- openWorldHint: false
convert_hourly_to_salaryConvert an hourly wage into gross annual, monthly, semimonthly, biweekly, weekly, and daily pay, including overtime.1 finding
Why it is in this group
- The name "convert_hourly_to_salary" 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_hourly_to_salary" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

Description, as the server wrote it Convert an hourly wage into gross annual, monthly, semimonthly, biweekly, weekly, and daily pay, including overtime. Uses the same formula as the AuraCalcs hourly to salary page. This is gross pay before tax. Estimate only.
Annotations the server declares
- readOnlyHint: true

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.
The server marks "convert_hourly_to_salary" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

History

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": [],
"ask": [
"mcp__calculators__calculate_paycheck",
"mcp__calculators__convert_hourly_to_salary"
],
"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 calculators. 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.
