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
redirect_chainFollow a URL through its full redirect chain (up to 8 hops) and report each hop's status code and Location target.Can send data outNo findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
What it can reach
- 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 Follow a URL through its full redirect chain (up to 8 hops) and report each hop's status code and Location target. Use to detect redirect loops or http->https and www canonicalisation issues.

Description, as the server wrote it Resolve DNS records (A/AAAA/MX/TXT/NS/CNAME/SOA) for a domain, queried live against 1.1.1.1. Use when you need to verify a domain resolves, check mail routing, or inspect TXT/SPF records.
http_headFetch a URL and report HTTP status, total latency in ms, key response headers (server, cache, content-type) and the page title.Reads text others writeCan send data outNo findings
Why it is in this group

What it can reach

- outboundThe input takes a URL (input.url): a request to a URL can carry data to whoever runs it.
Claude Code: ask, because it is tagged outbound.
Description, as the server wrote it Fetch a URL and report HTTP status, total latency in ms, key response headers (server, cache, content-type) and the page title. Use as a cheap liveness/uptime probe.

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 write3
- Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
- Can send data out6
- 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.
{
"permissions": {
"allow": [
"mcp__dirfast__dns_lookup",
"mcp__dirfast__ssl_check",
"mcp__dirfast__ip_echo"
],
"ask": [
"mcp__dirfast__http_head",
"mcp__dirfast__security_headers",
"mcp__dirfast__redirect_chain",
"mcp__dirfast__seo_snapshot",
"mcp__dirfast__robots_txt",
"mcp__dirfast__site_audit"
],
"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 dirfast. Review it before you use it.
