Concurrent two-client overlap probe proving MCP servers do not cross-deliver tool results.

Anlyon alternative
2 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 2Claude Code: ask
probe_isolationRun a full concurrent-client isolation probe against an operator-authorised MCP server; returns a signed per-surface verdict.No findings
Why it is in this group
- The description's first verb is "run": a word for a change.
Description, as the server wrote it Run a full concurrent-client isolation probe against an operator-authorised MCP server; returns a signed per-surface verdict.
verify_receiptVerify a signed verdict receipt.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 Verify a signed verdict receipt.
Only reads 1Show 1 read-only tool
get_verdictLatest signed verdict on file for an endpoint.Reads private dataReads text others writeCan send data outNo findings
Why it is in this group
- The name "get_verdict" says "get": a word for reading.
What it can reach
- private-dataThe description's first sentence says "file": it reads files.
- untrusted-inputThe input takes a URL (input.endpoint), and the tool reads it: it reads web pages, which anyone can write.
- outboundThe input takes a URL (input.endpoint): 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 Latest signed verdict on file for an endpoint.
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.
1 path 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 write1
- 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.

}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": [],
"ask": [
"mcp__concurrent-client-isolation-probe__probe_isolation",
"mcp__concurrent-client-isolation-probe__get_verdict",
"mcp__concurrent-client-isolation-probe__verify_receipt"
],
"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 concurrent-client-isolation-probe. Review it before you use it.

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