With Anlyon

1 tool here can delete or cancel things. Govern it.

Anlyon lists the tools and adopts none.
Each tool you adopt gets approvals and receipts.
Your agent never holds the key.

A tool your agent calls directly is not routed through Anlyon and is not governed by it. anlyon.dev only lists and labels, and these labels are the same either way.

What the NetSendo website MCP server can do

The NetSendo website MCP server is published by netsendo.com, a domain the MCP Registry verified. It has 10 tools. It can delete or cancel things (1 tool: unsubscribe_release_alerts) and create or change data (1 tool: subscribe_release_alerts). 8 tools only read.

5 tools read private data (list_releases, search_blog, list_docs and 2 more); 6 tools bring in text other people can write (list_releases, search_blog, get_blog_post and 3 more).

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 outbound.

Reads private data5: Reads files, mail, messages, databases, secrets, calendars or repositories.; get_doc
get_my_release_alerts
list_docs
list_releases
search_blog
Reads text others write6: Brings in text someone else can write: web pages, inbound email, messages, issues and comments.; get_blog_post
get_my_release_alerts
list_releases

subscribe_release_alerts
unsubscribe_release_alerts
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.

Remote posture

What anyone on the internet sees at the remote endpoint: an anonymous initialize and tools/list, and the public OAuth metadata.

HighThe whole server
The endpoint served tools/list without credentials, and the list has 2 tools that change things (1 destructive, 1 write). Whether a call also works without credentials was not tested: tools are never called.

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. Review it before you use it.
