ExerciseBank

exercisebank-mcp

A Model Context Protocol server for the ExerciseBank API: 1,492 studio-filmed exercises with a hand-checked classification and a ranked map of which exercises can replace which. It lets Claude, Cursor and other MCP clients search real exercises by muscle, equipment, movement pattern, difficulty and joints to avoid, so a plan is built from exercises that exist, with videos your app is licensed to show.

Use it while you build on the API (your coding agent explores the catalogue and the vocabulary as it writes your integration) or to prototype a workout generator before writing any code.

Install

Get a free sandbox key (no card) at https://exercisebank.net/signup, then:

Claude Code

claude mcp add exercisebank --env EB_KEY=eb_live_… -- npx -y exercisebank-mcp

Claude Desktop, Cursor, Windsurf and other clients (claude_desktop_config.json, .cursor/mcp.json, …)

{
  "mcpServers": {
    "exercisebank": {
      "command": "npx",
      "args": ["-y", "exercisebank-mcp"],
      "env": { "EB_KEY": "eb_live_…" }
    }
  }
}

It runs on your machine over stdio; the key stays in your client's configuration. Node 18 or later.

Tools

Tool	What it does
get_vocabulary	The exact filter values: muscles, equipment, movement patterns, joints, impact; the catalogue version; the ids a sandbox key gets video for
search_exercises	Search and filter: q, muscle, equipment (the gear the person has), pattern, minDifficulty, maxDifficulty, excludeJoints, impact, unilateral, limit, offset
get_exercise	The full record: description, coaching cues, French, classification
get_substitutes	Ranked replacements with a score and a reason each, filtered by gear and joints to avoid
get_media_urls	Signed video and still URLs. Only when EB_END_USER is set (below)

Video

ExerciseBank signs media only for a named person, and that person counts as an end user on the plan. To get get_media_urls, add an opaque id for whoever is at this machine:

"env": { "EB_KEY": "eb_live_…", "EB_END_USER": "dev-laptop-anna" }

URLs expire after 15 minutes. A sandbox key gets media for the 50-exercise sample listed by get_vocabulary; a paid plan gets all 1,492.

In your product

This server is for the developer's desk. A product calls the API from its own backend, with its own users' ids: use the exercisebank client and see the guide, an AI workout generator with Claude.
