## Quality 88/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-06-18; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 93 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 4 of 4 tools declare readOnlyHint or destructiveHint
- warn `tools.directory_hints`: 3 of 4 tools declare all four hints; missing: registry_stats (openWorldHint)
- pass `tools.token_cost`: about 988 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: no tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 4, about 988 tokens to load them all
- tool set hash: b7751463b0b93bc396203146120225ce
- badge: [![protogrid quality](https://protogrid.dev/badge/com.neuronto/agents-tools-search-discovery-ard-registry.svg)](https://protogrid.dev/servers/com.neuronto/agents-tools-search-discovery-ard-registry)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (4)

- `find_resource`: 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.
- `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.
- `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.
- `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.
