Available tools 7

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

carb

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

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

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

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

hydration

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

pace

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

race-time-predictor

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

Fuelcenter — questions

Answers built from our own checks of this server.

What can Fuelcenter do?

It exposes 7 tools, read directly from the server on our last check. Among them: carb-loading, fueling-plan, gel-comparison, heat-adjustment, hydration, pace-calculator and 1 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Fuelcenter working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 69 of 91 checks got a reply (75.8%), average response time 365 ms. The bar chart above shows every period we have measured.

Is Fuelcenter still maintained?

The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.

How do I connect Fuelcenter?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Fuelcenter need an API key?

No. Fuelcenter completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 7 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Fuelcenter?

It answers our handshake in 365 ms on average, which is faster than 38% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
