## Quality 91/100 (strong)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-06-18; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### 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`: 7 of 7 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 1,504 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: 7, about 1,504 tokens to load them all
- tool set hash: 0b1d22fe86865acaa155edc977198f61
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.codymcc4/fuelcenter.svg)](https://protogrid.dev/servers/io.github.codymcc4/fuelcenter)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (7)

- `carb-loading`: Calculate pre-race carb loading targets by race type, body weight, finish time, and experience level. Returns daily carb target, protocol length, total carbs, and pre-race meal size.
- `fueling-plan`: Build a minute-by-minute race or long-run fueling plan. Returns target carbs/hour, gel count, gel timing schedule, and total carbs. This is the core FuelCenter tool.
- `gel-comparison`: Return the FuelCenter gel catalog (SiS Beta Fuel, Maurten, Precision, GU, Tailwind, Spring, Carbs Fuel, neversecond, Huma) with carbs, price, caffeine, weight, and carbs-per-dollar. Optionally sort.
- `heat-adjustment`: Estimate how temperature and humidity will slow your race pace and change your fluid needs. Returns adjusted pace, slowdown percent, dew point, risk level, and fueling note.
- `hydration`: Estimate fluid and sodium needs for a race or long run based on body weight, duration, intensity, temperature, and humidity.
- `pace-calculator`: Given any two of distance, total time, or pace-per-mile, calculate the third. Returns pace per mile, per km, splits, and speed.
- `race-time-predictor`: Predict your finish time at common distances (5K through 100 miles) from a recent race result using the Riegel formula.
