Anlyon alternative
1 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
- The description's first verb is "start": a word for a change.
What it can reach
- untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
- outboundThe input takes a URL (input.url): a request to a URL can carry data to whoever runs it.
Description, as the server wrote it Start a real PageSpeed Insights measurement of a web page: the original site vs. its copy accelerated by WebSpeed Fast (mobile and desktop). Returns an audit_id immediately; the run takes 2–5 minutes, and get_measurement reads it when the user asks. If the page was measured before, its full result is returned at once. Results are published as a report page on webspeed.pro. Use when the user asks why a site is slow, how fast it is, or what can be sped up.

Why it is in this group
- The name "get_measurement" says "get": a word for reading.
Description, as the server wrote it Status or result of a measurement started with measure_site. While running, returns the queue position or progress. When done, returns the verified comparison and what else slows the page down. Quote numbers only from this result and keep its wording about estimates; if it says there is nothing to judge, do not invent numbers.
Annotations the server declares

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.
- Reads private data0
- Reads files, mail, messages, databases, secrets, calendars or repositories.
- Reads text others write1
- Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
- Can send data out1
- 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.
Install

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__webspeed__get_measurement"
],
"ask": [
"mcp__webspeed__measure_site"
],
"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 webspeed. Review it before you use it.
Capability tags behind 1 rule

Keep the decision: fail CI when the tools change, follow every change, or show a badge.
