## Connection (mcpServers)

```json
{
  "mcpServers": {
    "arrivalgraph": {
      "type": "http",
      "url": "https://ozeejewwpjmabshxyitc.supabase.co/functions/v1/arrivalgraph-mcp",
      "headers": {
        "X-API-Key": "${X_API_KEY}"
      }
    }
  }
}
```

Placeholders to fill: `${X_API_KEY}`.

## Trust

- hygiene: 80
- liveness: 0
- freshness: 85
- provenance: 45
- drivers: +website -unreachable(12 failures) ~updated-31d-ago -no-repository
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 94/100 (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 carries no ttlMs, so clients re-fetch it

### 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`: 1 of 1 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 199 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

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

- n/a `stability.changes`, `stability.rug_pull`: tool history not recorded yet

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

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

- tools: 1, about 199 tokens to load them all
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.kurious8282/arrivalgraph.svg)](https://protogrid.dev/servers/io.github.kurious8282/arrivalgraph)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (1)

- `get_arrival_context`: Use when an agent has a Seoul WGS84 destination coordinate and needs the actual matched building, floors, official elevator-presence fact, footprint size, registry ID, or structural arrival context for delivery/logistics, map enrichment, or physical-world planning. Do not use for general POI search, business discovery, traffic ETA, or turn-by-turn routing. Unverified entrance, elevator-location, parking-entry, loading-zone, access-rule, and observed-time facts remain null rather than inferred.
