MOST DANGEROUS TOOLS

High Risk

The most dangerous Dev Loop tools

Execute · High start_debug_loop This tool initiates an automated debug loop, which will execute diagnostic code, modify files, run tests, and potentially alter the codebase based on AI interpretation of a symptom description. Execute · High start_loop This tool triggers automated code generation, testing, and version control operations that execute complex external workflows. Execute · Medium advance_loop This tool drives a state machine through its lifecycle stages, triggering subsequent operations (tests, code generation, PR creation) based on reported outcomes. Write · Medium write_file The tool modifies repository content by creating or overwriting files.

4 of Dev Loop'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 Dev Loop

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

Rate limit write operations

{
  "write_file": {
    "limits": [
      {
        "counter": "write_file_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "loop_status": {
    "limits": [
      {
        "counter": "loop_status_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 Dev Loop — 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 Dev Loop

How do I prevent bulk modifications through Dev Loop? +

The Dev Loop server has 1 write tools including write_file. 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 Dev Loop.

How many tools does the Dev Loop MCP server expose? +

6 tools across 3 categories: Execute, Read, Write. 2 are read-only. 4 can modify, create, or delete data.

How do I enforce a policy on Dev Loop? +

Register the Dev Loop 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 Dev Loop tool call.

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