Anlyon alternative

3 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.

    Why it is in this group

    • The description's first verb is "start": a word for a change.
    Description, as the server wrote it
    Start here. Check whether people have asked for a product and could not buy it. Returns matching exNiche gaps at summary level (verdict, score band, class, trend, source counts, one linked ask) and records your ask as one AI agent search. 1 credit. Never send personal details or synthetic asks.

      What this check looks for
    Description, as the server wrote it
    Full dossier for a scored gap: product-by-product checks, live closest products, supplier candidates and a suggested spec. Needs a workspace key. Unlocking costs 19,000 credits once per account; an already unlocked dossier costs 0. Ask the user before unlocking.

  • report_not_foundFree.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
    Free. Report a genuine shopper mismatch after a search. Do not send synthetic reports or personal details. Response states whether the agent observation was saved; it is not verified human demand.

    Why it is in this group

    • The name "get_gap" says "get": a word for reading.
    Description, as the server wrote it
    Get one gap by id or slug. detail=summary costs 1 credit; detail=full (exact score parts, every ask with link and attribution, requirements, 8-week ask counts) costs 100 credits. Unscored leads only return summary.

    • The name "list_gaps" says "list": a word for reading.
    Description, as the server wrote it
    List the exNiche gap ledger with filters. detail=summary costs 1 credit per call; detail=full adds exact scores, all linked asks and requirements for 10 credits per scored row. Scores mean 'worth a closer look', not verified demand.

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 write2
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.

    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.

All changes to this server

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__search__list_gaps",
      "mcp__search__get_gap",
      "mcp__search__search_products",
      "mcp__search__get_setup_and_upgrade_links"

      "mcp__search__get_dossier",
      "mcp__search__report_not_found"
    ],
    "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 search. Review it before you use it.
