Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.

Tool list from our last check. Connect live to refresh it.

find_resource Read-only

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.

querystring, required

The task, in plain language. For example: 'scrape a website behind cloudflare'.

kindstring

Restrict to one family of resource. Matching is normalised, so 'mcp-server' finds them under every media type in circulation, and 'a2a-agent' or 'agent' both reach A2A cards and ACP, OASF and AgentFacts descriptors. 'webmcp' is browser-page tools, which are not callable servers.

limitinteger

networkstring

Payment network, for example base, solana, tempo or stripe.

paymentstring

Keep only resources with this payment requirement. 'free' means none is known; 'payable' means a price or a 402 is known.

federateboolean

Also query upstream registries live and fuse the rankings. Off is faster.

max_price_per_callnumber

Most you will pay for one call, in US dollars. A resource whose price is unknown is excluded.

find_tool

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.

read-only

Argument	Type	Description
limit	integer
query*	string	What the tool should do. For example: 'extract text from a pdf'.
with_schema	boolean	Include each tool's full JSON input schema. Verbose; off by default.

  "type": "object",
  "required": [
    "query"

  "properties": {
    "limit": {
      "type": "integer",
      "default": 10,

      "default": false,
      "description": "Include each tool's full JSON input schema. Verbose; off by default."
    }
  }
}

publish_resource

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.

Argument	Type	Description
domain	string	A domain serving /.well-known/ard.json, e.g. example.com
endpoint	string	Absolute URL of an MCP server, e.g. https://example.com/mcp

Input schema (JSON)

{
  "type": "object",
  "properties": {
    "domain": {
      "type": "string",
      "description": "A domain serving /.well-known/ard.json, e.g. example.com"
    },
    "endpoint": {
      "type": "string",
      "description": "Absolute URL of an MCP server, e.g. https://example.com/mcp"
    }
  }
}

registry_stats

How large this index is, what it holds, how much of it has been verified by introspection, and which upstream registries are federated.
