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.

Tools

Grouped by what each tool does, most consequential first. Open one for its reasons and full description; descriptions are the publisher's own words.

Changes things 2Claude Code: ask
  • application_system_factsFacts about an application system (ATS) from applications Haystack's AI agent sent: how many fields its forms have, the questions they ask most, and how fast employers on it reply.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.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Facts about an application system (ATS) from applications Haystack's AI agent sent: how many fields its forms have, the questions they ask most, and how fast employers on it reply. Without a system, the overall figures.

    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    What Haystack knows about applying to an employer: live roles, the share of applications that got a reply, the median time to the first reply, how many fields its form has and the questions it asks. Pass no company to get the employers most likely to reply to an application.

    Why it is in this group

    • The name "get_job" says "get": a word for reading.

    What it can reach

    • untrusted-inputThe description's first sentence says "reply": it reads comments, which other people can write.
    Description, as the server wrote it
    One job's details by its Haystack id: title, employer, location, pay, work mode, skills, what the advert says (no experience, no degree, visa sponsorship), the description, and facts about applying to that employer from Haystack's data (reply rate, time to reply, form questions) when known.

    Annotations the server declares

    • title: Get a job
    • readOnlyHint: true
    • destructiveHint: false
    • idempotentHint: true
    • openWorldHint: false
  • search_jobsSearch live jobs on Haystack, newest first.No findings

    Why it is in this group

    • The name "search_jobs" says "search": a word for reading.
    Description, as the server wrote it
    Search live jobs on Haystack, newest first. Filter by job title words, country, city, remote, and by what the advert says: no experience needed, no degree needed, visa sponsorship offered. Returns up to 20 jobs, each with its link, and an Auto Apply link when Haystack's AI agent can fill in and submit the employer's form.

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 outbound.

Reads private data0
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

Pinned to version 1.0.0. Values in angle brackets are yours to fill in.

claude mcp add --transport http jobs https://haystackapp.io/mcp
claude mcp add --transport http jobs https://haystackapp.io/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": [
      "mcp__jobs__search_jobs",
      "mcp__jobs__get_job"
    ],
    "ask": [
      "mcp__jobs__employer_facts",
      "mcp__jobs__application_system_facts"
    ],
    "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 jobs. 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.
