Remote MCP server · Claude, Claude Code, Cursor

An MCP server for timed workouts

Rhylthyme Gym turns Claude into your training copilot. Ask for any workout and Claude returns a live timeline with real-time set/rest timers, interval beeps, and superset coordination — exactly what you need on your phone at the rack.

How it differs from Rhylthyme

Rhylthyme Gym is the regular Rhylthyme connector, set up for training:

Search starts in workouts. Catalog searches default to workouts; Claude can still search everything else when you ask.
Two shortcuts. start_workout finds the best-matching workout and opens its live timeline in one step; surprise_workout picks a random workout.
Links open on gym.rhylthyme.com. Live timelines and program pages use this site.

Every other tool is the same, and so is your account: programs you save are in the same library either way. Install one or the other; if you schedule more than training, use Rhylthyme.

Install

In Claude Desktop, open in the sidebar. Customize in the Claude sidebar, with the Connectors tab

Open the tab, click , then . Add menu with the Add custom connector option

Name it rhylthyme-gym (or anything you like) and paste this URL:

https://gym.rhylthyme.com/mcp

Click .

Add custom connector dialog with Name and MCP server URL fields

Rhylthyme's tools appear under the connector — Claude picks the right one automatically when you talk.

Advanced: edit claude_desktop_config.json

To wire it up through the config file instead, add this to your mcpServers block (it needs Node.js for npx):

{
  "mcpServers": {
    "rhylthyme-gym": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://gym.rhylthyme.com/mcp"]
    }
  }
}

Reach the file via Settings → Developer → Edit Config, then restart Claude Desktop.

Other MCP clients

Rhylthyme is a remote MCP server (Streamable HTTP, no sign-in needed for the public tools), so any client that takes a server URL can use it.

Claude Code

claude mcp add --transport http rhylthyme-gym https://gym.rhylthyme.com/mcp

Cursor and other clients: add it to the client's mcpServers settings (for Cursor, ~/.cursor/mcp.json):

{
  "mcpServers": {
    "rhylthyme-gym": { "url": "https://gym.rhylthyme.com/mcp" }
  }
}

What it doesn't do

No tracking, no ads, no personal data shared with Anthropic or third parties
No login required for public workouts
Optional account to save your own (Google / Apple / email magic link)
Tool returns are markdown summaries — full data only fetched when you open the live timeline

Why Rhylthyme

Built for workouts where timing is the whole point — intervals, supersets, AMRAP, rest periods.
