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.

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.
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 Check right now whether a website/URL is up: HTTP status, response time (ms) from Cloudflare's edge, redirect chain and final URL, content type/size, server header, and which security headers (HSTS, CSP, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy) are present or missing. Free, no key.
Annotations the server declares

- openWorldHint: true

start_uptime_monitorMonitor up to 3 URLs every ~5 minutes and send DOWN/UP alerts to a Slack or Discord webhook or a Telegram bot, plus a public status page.Can send data outNo findings
Why it is in this group
- The name "start_uptime_monitor" says "start": a word for a change.
What it can reach
- outboundThe input takes a destination (input.chat_id): what the tool writes goes there.
- outboundThe input takes a URL (input.urls): a request to a URL can carry data to whoever runs it.
Description, as the server wrote it Monitor up to 3 URLs every ~5 minutes and send DOWN/UP alerts to a Slack or Discord webhook or a Telegram bot, plus a public status page. Free 7-day trial, no signup. UpLane Pro: 50 URLs, 7 USDC/month (key UP-... from https://uplane.deanhiki.workers.dev/#pro).
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 write2
- Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
- Can send data out3
- 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 3 tools that change things (3 write). Whether a call also works without credentials was not tested: tools are never called.
What this check looks forMatched text
https://uplane.deanhiki.workers.dev/mcp: tools/list returned 3 tools to an anonymous client, including check_website (write), check_websites (write), start_uptime_monitor (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.
Install
Pinned to version 1.0.0. Values in angle brackets are yours to fill in.
claude mcp add --transport http website-uptime https://uplane.deanhiki.workers.dev/mcpclaude mcp add --transport http website-uptime https://uplane.deanhiki.workers.dev/mcpRun in a terminal.
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__website-uptime__check_website",
"mcp__website-uptime__check_websites",
"mcp__website-uptime__start_uptime_monitor"
],
"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 website-uptime. Review it before you use it.
Capability tags behind 3 rules
- mcp__website-uptime__check_website untrusted-input, outbound
- mcp__website-uptime__check_websites untrusted-input, outbound

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.
