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.

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Checks a contact or lead CSV (passed as text, up to 500 data rows and 64 KiB) before a CRM import and reports what it finds: duplicate emails (matched ignoring case and surrounding spaces), invalid email syntax, role or shared inboxes (info@, sales@ and similar), blank required fields (placeholders like N/A, null and - count as blank), phone numbers not written as + country code and digits only (with a suggested form when the fix is mechanical), country and state spelling drift, mixed or ambiguous date formats, and file problems (garbled characters, ragged rows, formula-like cells, stray spaces, header issues). Detection only: it changes nothing, returns no cleaned file, and does not store or log your CSV. Pattern-based; it does not check that mailboxes exist. Same checks as the free Sales List Rescue CSV preflight checker on pureservices.store.

    • The description's first verb is "run": a word for a change.

    • Warn

      The server marks "preflight_sample" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

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.

Findings

Matches of fixed checks, with the text they matched.

1 warn
  • Warnpreflight_sample

    What this check looks for

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 0.1.0. Values in angle brackets are yours to fill in.

claude mcp add --transport http crm-csv-preflight https://pureservices.store/mcp
claude mcp add --transport http crm-csv-preflight https://pureservices.store/mcp

Run 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.

.claude/settings.json
{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__crm-csv-preflight__preflight_csv",
      "mcp__crm-csv-preflight__preflight_sample"
    ],
    "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 crm-csv-preflight. Review it before you use it.

Pin

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

Pin in CI

Fail a build when the tools you reviewed are not the tools the server serves today.
