Anlyon alternative
1 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 1Claude Code: ask
create_test_addressCreate a temporary echo.email address.No findings
Why it is in this group
- The name "create_test_address" says "create": a word for a change.
Description, as the server wrote it Create a temporary echo.email address. Send one email to it from the system under test, then call wait_for_report with the returned token and key. The address dies after 10 minutes without a wait_for_report call and accepts one message.
Only reads 2Show 2 read-only tools
get_reportFetch a finished report as JSON: the digest plus every check (SPF trace, DKIM, DMARC, BIMI, TLS, IPv6, images, links, unsubscribe, headers, DNS log).No findings
Why it is in this group
- The name "get_report" says "get": a word for reading.
Description, as the server wrote it Fetch a finished report as JSON: the digest plus every check (SPF trace, DKIM, DMARC, BIMI, TLS, IPv6, images, links, unsubscribe, headers, DNS log).
wait_for_reportWait up to timeout_s seconds (max 50) for the email sent to a test address to be analysed.Reads private dataReads text others writeNo findings
Why it is in this group
- The name "wait_for_report" says "wait": a word for reading.
What it can reach
- private-dataThe description's first sentence says "wait" and "email": it reads mail.
- untrusted-inputThe description's first sentence says "wait" and "email": it reads inbound email, which other people can write.
Description, as the server wrote it Wait up to timeout_s seconds (max 50) for the email sent to a test address to be analysed. Returns status waiting or received (call again), or done with a digest: score, SPF, DKIM, DMARC, TLS, IPv6 and the failing sender requirements.
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 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 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.
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

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__deliverability__wait_for_report",
"mcp__deliverability__get_report"
],
"ask": [
"mcp__deliverability__create_test_address"
],
"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 deliverability. Review it before you use it.

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