MOST DANGEROUS TOOLS

High Risk

The most dangerous Hevy MCP tools

Write · Medium create_routine This tool creates new workout routine data in the user's Hevy account. Write · Medium create_workout Creating a new workout record is a write operation—it modifies the user's fitness data by adding a new entry. Write · Medium update_routine The 'update_routine' prefix indicates data modification. Write · Medium update_workout The tool modifies existing workout records reversibly (typical updates can be corrected or changed again).

4 of Hevy MCP's 10 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Hevy MCP

PolicyLayer is an MCP gateway — it sits between your AI agents and Hevy MCP, and nothing reaches the server without passing your rules. These are the rules we recommend:

Rate limit write operations

{
  "create_routine": {
    "limits": [
      {
        "counter": "create_routine_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "get_routine": {
    "limits": [
      {
        "counter": "get_routine_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

Controls API costs and prevents retry loops from exhausting upstream rate limits.

Create a free account and register Hevy MCP — nothing to install.
Add these rules — paste them, or build them visually. Tune the limits to your setup.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
