No check matched anything in the tool definitions. No finding is not a safety guarantee. How the checks work.
claude mcp add --transport http k-work-trust https://k-work-trust-api.fly.dev/mcpTools
Open a tool for its reasons and full description. Descriptions are the publisher's own words, shown as they are.
3 tools
Changes things 2Claude Code: ask
addAdds two numbers and returns the sum.No findings
Why it is in this group
- The name "add" says "add": a word for a change.
Description, as the server wrote it Adds two numbers and returns the sum.
echoEchoes the provided text back to the caller.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it Echoes the provided text back to the caller.
Only reads 1Claude Code: allow
server_timeReturns the current server time (ISO 8601, UTC).No findings
Why it is in this group
- The description's first verb is "return": a word for reading.
Description, as the server wrote it Returns the current server time (ISO 8601, UTC).
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 or untrusted-input or outbound.
- Reads private data0
- Reads files, mail, messages, databases, secrets, calendars or repositories.
- Reads text others write0
- Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
- 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.

- WarnThe whole server
The endpoint served tools/list without credentials, and the list has 2 tools that change things (2 write). Whether a call also works without credentials was not tested: tools are never called.
What this check looks forMatched text
https://k-work-trust-api.fly.dev/mcp: tools/list returned 3 tools to an anonymous client, including echo (write), add (write)
Install
Pinned to version 0.1.0. Values in angle brackets are yours to fill in.
claude mcp add --transport http k-work-trust https://k-work-trust-api.fly.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": [
"mcp__k-work-trust__server_time"
],
"ask": [
"mcp__k-work-trust__echo",
"mcp__k-work-trust__add"
],
"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 k-work-trust. Review it before you use it.
