## Trust

- hygiene: 100
- liveness: 99
- freshness: 85
- provenance: 80
- drivers: +repository +namespace-matches-repo +reachable +uptime-97% ~updated-59d-ago
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 80/100 (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: 71 (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
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: get_weather_alerts (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); geocode_location (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_forecast (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 1,172 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: 67 (weight 15)

- pass `deps.known_vulns`: no known advisory in 98 resolved packages
- fail `deps.mcp_sdk_version`: @modelcontextprotocol/sdk 1.30.1 has 1 known advisory (GHSA-6qxp-vccf-f47h); update @modelcontextprotocol/sdk to 1.31.0 or later
- pass `deps.resolvable`: met-mcp@0.2.0 resolved: 98 packages

- tools: 8, about 1,172 tokens to load them all
- tool set hash: 2cb4e85063f35172250b8b228ed8ed67
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.trondbjoroy/met-mcp.svg)](https://protogrid.dev/servers/io.github.trondbjoroy/met-mcp)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.
