Anlyon alternative
Run the operations that matter 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 name "sitemap_preview" says "preview": a word for reading.
Description, as the server wrote it Free keyless site enumeration: discover a domain's sitemaps (robots.txt, fallback /sitemap.xml) and return up to 20 page URLs with lastmod. The paid /web/sitemap ($0.003) returns up to 5000 URLs across 10 sitemap files with a substring filter — call get_premium_access.

Why it is in this group
- The name "web_extract_preview" says "preview": a word for reading.
What it can reach
- untrusted-inputThe name "web_extract_preview" says "preview" and "web": it reads web pages, which anyone can write.
- untrusted-inputThe description's first sentence says "web": it reads web pages, which anyone can write.
- untrusted-inputThe input takes a URL (input.url), and the tool reads it: it reads web pages, which anyone can write.
- 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 Free keyless live web read: fetch ONE public URL now and get the title, metadata and boilerplate-stripped main-content text (JS/SPA pages recovered without a browser), plus a prompt-injection screen flag. SSRF-guarded. Markdown, the full link graph and 10-URL batches are in the paid /web/extract ($0.003) — call get_premium_access.
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.
2 paths in this server alone from private data, through text someone else wrote, to a way out. Denying 1 outbound tool breaks every one.
- Reads private data1
- 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 out1
- Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.

"permissions": {
"deny": [

}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
Pinned to version 0.1.1. Values in angle brackets are yours to fill in.
claude mcp add --transport http web-extract https://jobs.greyridgesignals.ai/mcp/webclaude mcp add --transport http web-extract https://jobs.greyridgesignals.ai/mcp/webRun 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": [
"mcp__web-extract__sitemap_preview",
"mcp__web-extract__get_premium_access"
],
"ask": [
"mcp__web-extract__web_extract_preview"
],
"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 web-extract. Review it before you use it.
Capability tags behind 2 rules
- mcp__web-extract__web_extract_preview untrusted-input, outbound
- mcp__web-extract__get_premium_access private-data, untrusted-input

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