Unmeasured means there is not enough evidence to decide. How these checks work

Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 628 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-06-18, serverInfo.name fuelcenter-mcp.

  • Pass
    Lists tools

    tools/list returned 7 tools.

  • Pass
    Current protocol

    Negotiated 2025-06-18. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 628 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 628 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

  • Not measured
    Free tier cited

    No publisher quote has been checked.

Tools

  • Pass
    Tools described

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

  • Pass
    Parameters documented

    33 of 33 parameters have a description (100%). The bar is 80%.

  • Pass
    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Not measured
    Website matches publisher

    This namespace is not a reverse domain, so the website comparison does not apply.

  • Pass
    Source repo linked

    A repository URL is on file.

  • Pass
    Repo owner matches

    The GitHub repository owner matches the namespace login.

  • Fail
    Recently updated

    Updated 2026-04-17T18:04:35.742191Z, which is older than 180 days.

Capabilities

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.

Discovered
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.

Discovered
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.

Discovered
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.

Discovered
hydration

Estimate fluid and sodium needs for a race or long run based on body weight, duration, intensity, temperature, and humidity.

Discovered
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.

Discovered
race-time-predictor

Predict your finish time at common distances (5K through 100 miles) from a recent race result using the Riegel formula.
