## 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`: 3 of 3 tools declare readOnlyHint or destructiveHint
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: diagnose_symptom (idempotentHint); maintenance_schedule (idempotentHint); lookup_procedure (idempotentHint)
- pass `tools.token_cost`: about 468 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`: 3 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: 3, about 468 tokens to load them all
- tool set hash: d07d77606941438717977028785f3a70
- tools last changed: 2026-10-01T23:04:27.045Z
- badge: [![protogrid quality](https://protogrid.dev/badge/sr.rush/maintenance.svg)](https://protogrid.dev/servers/sr.rush/maintenance)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (3)

- `diagnose_symptom`: Use this when you need to understand why your Rush SR has a symptom, such as why won't my Rush SR start. Do not use for a service interval or a step-by-step repair procedure. Covers the Rush SR only: do not use for other vehicles or for buying advice.
- `lookup_procedure`: Use this when you need steps for a task, such as how do I bleed the brakes on my Rush SR. Do not use for a symptom diagnosis or a service interval lookup. Covers the Rush SR only: do not use for other vehicles or for buying advice.
- `maintenance_schedule`: Use this when checking a Rush SR service interval or maintenance schedule for a component, such as how often to change brake fluid or when the chain needs service. Each result says which service interval it belongs to (every session, weekend, month, year, or 150+ hours), so pick the one that matches the car's hours or sessions. Do not use for troubleshooting a symptom or a repair procedure. Covers the Rush SR only: do not use for other vehicles or for buying advice.
