**An agent can connect on its own if it already holds `KR_GROUNDTRUTH_TOKEN`.** Remote endpoint behind a static API key or header. The registry never sees the value; the agent fills the placeholder.

## Connection (mcpServers)

```json
{
  "mcpServers": {
    "kr-groundtruth": {
      "type": "http",
      "url": "https://kr-groundtruth-mcp.vercel.app/api/mcp",
      "headers": {
        "Authorization": "Bearer ${KR_GROUNDTRUTH_TOKEN}"
      }
    }
  }
}
```

Placeholders to fill: `${KR_GROUNDTRUTH_TOKEN}`.

## Trust

- hygiene: 80
- liveness: 100
- freshness: 85

- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 89/100 (good)

### protocol: 88 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- warn `protocol.list_ttl`: tools/list declares ttlMs 0, so clients re-fetch it on every use

### 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: 86 (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`: 8 of 8 tools declare readOnlyHint or destructiveHint
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: search_corporation (destructiveHint, idempotentHint); apartment_trade_prices (destructiveHint, idempotentHint); search_law (destructiveHint, idempotentHint); …
- pass `tools.token_cost`: about 974 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: 8, about 974 tokens to load them all
- tool set hash: 85dd6b1a5330c6bbc6d78451080a3e85
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.ChloePark85/kr-groundtruth.svg)](https://protogrid.dev/servers/io.github.ChloePark85/kr-groundtruth)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.
