## Quality 70/100 (needs work)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers

### tool hygiene: 64 (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: kr_trade_exports_10day (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); kr_trade_pulse (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); site_profile (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …

### stability: 75 (weight 15)

- warn `stability.changes`: 47 tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

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