Agent Resource Discovery (ARD, IETF draft) registry: search every ARD registry + verified MCP tools

4 tools: 1 do something that can't be undone, 1 change things and 2 only read.

Tools: 0 delete, 1 irreversible, 1 write, 2 read.

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.

4 tools

Can't be undone 1Claude Code: ask
  • publish_resourceList an MCP server or an ARD-publishing domain in this index so other agents can discover it.Reads text others writeCan send data outNo findings

    Why it is in this group

    • The name "publish_resource" says "publish": a word for a change that another call does not undo.

    What it can reach

    • untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
    • outboundThe name "publish_resource" says "publish": it sends or publishes something to other people.
    • outboundThe input takes a URL (input.endpoint): a request to a URL can carry data to whoever runs it.
    Description, as the server wrote it
    List an MCP server or an ARD-publishing domain in this index so other agents can discover it. Give `endpoint` for an MCP server URL, or `domain` for a site that serves an ARD manifest. The submission is verified before it is indexed: an endpoint must complete an MCP initialize handshake, and a domain must serve a manifest that parses. Nothing is taken on trust, so a listing that succeeds here is one an agent can actually call. Free submissions are reviewed and listed within 30 days. Set priority=true to list now for 5 USDC (x402).

Changes things 1Claude Code: ask
  • registry_statsHow large this index is, what it holds, how much of it has been verified by introspection, and which upstream registries are federated.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
    How large this index is, what it holds, how much of it has been verified by introspection, and which upstream registries are federated.

Only reads 2Show 2 read-only tools
  • find_resourceSearch for an MCP server, skill, agent, API or other callable capability for a task, across this index and every other public ARD registry at once.Reads text others writeNo findings

    Why it is in this group

    • The name "find_resource" says "find": a word for reading.

    What it can reach

    • untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
    Description, as the server wrote it
    Search for an MCP server, skill, agent, API or other callable capability for a task, across this index and every other public ARD registry at once. Returns ranked matches with a relevance score, the endpoint to connect to, and which registries carry each result. The score is relevance only and is not a trust or safety rating. Filter by payment (free, payable, x402, mpp) and a maximum price per call: terms come from the publisher's manifest or the endpoint's own 402 answer, and the caller pays the provider directly. 2 free calls a day, then 0.1 USDC per call over x402 (or prepaid credits).

    Annotations the server declares

    • title: Find an agentic resource
    • readOnlyHint: true
    • destructiveHint: false
    • idempotentHint: true
    • openWorldHint: true
  • find_toolSearch individual MCP tools by name and behaviour, not the servers that host them.Reads text others writeNo findings

    Why it is in this group

    • The name "find_tool" says "find": a word for reading.

    What it can reach

    • untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
    Description, as the server wrote it
    Search individual MCP tools by name and behaviour, not the servers that host them. Every tool returned here was read back from a live server's tools/list, so the name and input schema are what the server actually exposes rather than what its description claims. Use this when you know the shape of the call you need; use find_resource when you are looking for a service. 2 free calls a day, then 0.1 USDC per call over x402 (or prepaid credits).

    Annotations the server declares

    • title: Find a specific verified tool
    • readOnlyHint: true
    • destructiveHint: false
    • idempotentHint: true
    • openWorldHint: true

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.

Reads private data0
Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write3
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.

Remote posture

What anyone on the internet sees at the remote endpoint: an anonymous initialize and tools/list, and the public OAuth metadata.

  • HighThe whole server

    The endpoint served tools/list without credentials, and the list has 2 tools that change things (1 irreversible, 1 write). Whether a call also works without credentials was not tested: tools are never called.

    Matched text

    https://neuronto.com/mcp: tools/list returned 4 tools to an anonymous client, including publish_resource (irreversible), registry_stats (write)

    What this check looks for

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.

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__agents-tools-search-discovery-ard-registry__find_resource",
      "mcp__agents-tools-search-discovery-ard-registry__find_tool"
    ],
    "ask": [
      "mcp__agents-tools-search-discovery-ard-registry__publish_resource",
      "mcp__agents-tools-search-discovery-ard-registry__registry_stats"
    ],
    "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 agents-tools-search-discovery-ard-registry. Review it before you use it.

Pin

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