## Connection (mcpServers)

```json
{
  "mcpServers": {
    "protogrid": {
      "type": "http",
      "url": "https://api.protogrid.dev/mcp"
    }
  }
}
```


## Trust

- hygiene: 80
- liveness: 99
- freshness: 100
- provenance: 55
- drivers: +dns-namespace +website +reachable +uptime-98% +updated-27d-ago -no-repository
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 95/100 (strong)

### protocol: 100 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- pass `protocol.list_ttl`: tool list is cacheable (ttlMs 3600000)

### 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: 100 (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`: 5 of 5 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 1,270 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 75 (weight 15)

- warn `stability.changes`: 16 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: 5, about 1,270 tokens to load them all
- tool set hash: 50a16f56ce605385430d5456a78c47d1
- tools last changed: 2026-10-02T09:43:13.125Z
- badge: [![protogrid quality](https://protogrid.dev/badge/dev.protogrid/registry.svg)](https://protogrid.dev/servers/dev.protogrid/registry)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Remotes

- https://api.protogrid.dev/mcp (streamable-http, auth none, reachable true, uptime30d 0.97528833)

## Packages

_none_

## Tools (5)

- `check_server`: Probe a remote MCP server URL once, credential-free and without calling its tools, and get its quality checks and its readiness for the Claude and OpenAI directories. Pass `url` to start a check (waits up to 25 s for the result), or `id` to read one. Quota: a few checks per hour anonymously, more with an API key.
- `get_connection`: Minimal connection block for the preferred remote (or package) with ${SECRET} placeholders, formatted for a target client. Secrets are never accepted or returned.
- `get_server`: Official server.json plus connectability (class, remotes with auth/health, packages), current tools, trust breakdown and identity for one server name.
- `list_tools`: Every current tool of a server with full input/output schemas, paginated by tool name.
- `search`: Hybrid (keyword + semantic) search over servers and their tools. Filter by connection class to keep only what you can reach autonomously (R0, R1).
