MOST DANGEROUS TOOLS

High Risk

The most dangerous Constraint tools

Execute · Medium constraint_diagnose This tool executes a diagnostic algorithm (4-order Goodman diagnostic) on user-supplied data. Execute · Medium constraint_funnel This tool executes a constraint-based audio transformation operation whose effects depend on supplied arguments (target pitch, intensity/gravity parameters). Execute · Medium constraint_render This tool executes an audio rendering operation that generates and writes output files (WAV format). Execute · Medium constraint_snap This tool executes a mathematical/algorithmic operation (pitch snapping to an Eisenstein lattice) whose output depends on the input MIDI pitch.

5 of Constraint's 6 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Constraint

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

Rate limit write operations

{
  "constraint_generate": {
    "limits": [
      {
        "counter": "constraint_generate_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "constraint_terrain_list": {
    "limits": [
      {
        "counter": "constraint_terrain_list_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 Constraint — 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.

FAQ

Questions about Constraint

How do I prevent bulk modifications through Constraint? +

The Constraint server has 1 write tools including constraint_generate. Set a rate limit in your policy -- for example, 10 calls per hour prevents an agent from making more than 10 modifications per hour. PolicyLayer enforces this at the gateway, before calls reach Constraint.

How many tools does the Constraint MCP server expose? +

6 tools across 3 categories: Execute, Read, Write. 1 are read-only. 5 can modify, create, or delete data.

How do I enforce a policy on Constraint? +

Register the Constraint MCP server in PolicyLayer, apply the suggested rules above (adjust the limits to your use case), and point your AI client at the PolicyLayer proxy URL instead of the server directly. Your agents keep the same tools; PolicyLayer evaluates every call against policy before it executes. Nothing to install, live in minutes.

Enforce policy on every Constraint tool call.

Deterministic rules across all 6 Constraint tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
