Overview

AI-generated overview

WorkoutX Exercise API gives an assistant 1,900+ exercises with video, workout and program generation, supplements, and developer helpers.

What you can do
  • Search, filter and read exercises, with instructions, muscles, equipment, calories and signed video links
  • Find alternatives or similar exercises, estimate calories, and map old v1 ids to v2
  • Generate a single workout session or a multi-week program, and look up supplements and stacks
  • Export exercise seed data as JSON or CSV and see trending exercises
  • Get endpoint references, generated TypeScript/Swift/Kotlin/Dart models, code examples and request diagnostics
  • Check API key validity, plan and usage stats
When to use it
Useful when building or prototyping fitness apps and workout screens, when an assistant needs exercise data with media, or when generating workouts, programs and supplement guidance. Also handy for debugging WorkoutX API requests and producing typed models.
Requirements
A WorkoutX API key, sent in the X-WorkoutX-Key header for the hosted endpoint at api.workoutxapp.com or set as WORKOUTX_API_KEY for the npm stdio bridge (npx workoutx-mcp). Network access required; a free plan offers 500 requests without a card.
Before you install
Every tool call counts as one API request against plan limits, and some tools (workout and program generation, supplements) require paid plans. Media links are signed and expire, so they should be refetched rather than stored. The API key is a secret; keep it out of URLs and client devices.

Installation

In SourceWeft

  1. Open WorkoutX Exercise API in the dashboard and add it to a workspace.
  2. Connect X-WorkoutX-Key credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.furkanuruk%2Fworkoutx/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

README

WorkoutX MCP Server — Exercise & Fitness API for AI Agents

[npm] [MCP] [license]

Give Claude Code, Cursor, ChatGPT, Grok, VS Code and Claude Desktop the WorkoutX Exercise API: 1,900+ exercises with 720p MP4 animations (male and female models), a workout and multi-week program generator, an evidence-rated supplement database, and developer tools for building fitness apps: typed models, code examples, request debugging and usage stats.

"Add a workout screen to the app using a 45-minute dumbbell chest session from WorkoutX." "Generate Swift models for exercises and workouts." "Why are we getting 429s since yesterday?"

  • Hosted endpoint: https://api.workoutxapp.com/mcp (Streamable HTTP) — nothing to run
  • Auth: your WorkoutX API key in the X-WorkoutX-Key header (or Authorization: Bearer)
  • Free plan: 500 requests, no credit card — get a key
  • Every tool call counts as one API request, with the same plan limits as the REST API
  • Docs and setup guide: workoutxapp.com/mcp.html
