What your AI can do with Fitness Tools
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “tdee”: Estimate BMR and TDEE via Mifflin-St Jeor, Harris-Benedict, Katch-McArdle, and Cunningham. Provide body_fat or lean_mass to unlock the LBM-b.”
“Use “adaptive-tdee”: Measure actual TDEE from a logged history of daily weight and/or calorie intake. Default method (kalman) is a joint Kalman filter over true.”
“Use “body-fat”: Estimate body-fat % via US Navy circumference, Jackson-Pollock 3-site skinfold, and Deurenberg (BMI-based) methods.”
“Use “one-rep-max”: Estimate 1RM from a submaximal set via Epley, Brzycki, Lombardi, Wathan, O'Conner, and Mayhew; returns a %1RM load chart.”
How secure is the Fitness Tools MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Fitness Tools holds up.
Official endpoint
Operated by Fitness Tools (workers.dev) at its documented MCP endpoint — not a third-party mirror or community re-host.
No sign-in needed
This server only exposes public data — no account and no credentials are involved when you connect.
Scanned before it goes live
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
Watched for drift
If Fitness Tools adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Connected in three steps

Who runs the Fitness Tools MCP server?
The Fitness Tools MCP server at a glance
https://fitness-tools-mcp.ajwallacemusic.workers.dev/mcpQuestions, answered
Is there an official Fitness Tools MCP server?
Yes — Fitness Tools operates its own remote MCP server at fitness-tools-mcp.ajwallacemusic.workers.dev. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.
How do I connect Fitness Tools to Claude or ChatGPT?
Add gate's gateway URL to your AI client once, then pick Fitness Tools in the directory. No account or sign-in is needed. From then on, Fitness Tools's tools are available in every client you've connected to gate.
Do I need to host anything?
No. Fitness Tools runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the Fitness Tools MCP server safe to connect?
It's the vendor's official endpoint, and gate scans its tools for prompt injection and hidden instructions before it goes live, re-checks it whenever it changes, and lets you allow, block, or require approval for every single tool.
Is it free?
Yes — you can get started with gate for free and connect Fitness Tools in minutes. No credit card required.
