MOST DANGEROUS TOOLS

High Risk

The most dangerous Mcp Rn Devtools tools

Execute · Medium force_gc Forcing garbage collection is an active runtime operation that triggers the JS engine to reclaim memory. Execute · High evaluate_js This tool permits arbitrary JavaScript execution within a running React Native app's runtime environment.

2 of Mcp Rn Devtools's 19 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Mcp Rn Devtools

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

Cap read operations

{
  "get_action_log": {
    "limits": [
      {
        "counter": "get_action_log_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 Mcp Rn Devtools — 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 Mcp Rn Devtools

Is the Mcp Rn Devtools MCP server safe to use without restrictions? +

The Mcp Rn Devtools server is primarily read-only with 17 read tools. While it cannot modify data, an agent in a retry loop can make thousands of API calls per minute, exhausting rate limits and running up costs. Rate limiting is still recommended.

How many tools does the Mcp Rn Devtools MCP server expose? +

19 tools across 4 categories: Destructive, Execute, Read, Write. 17 are read-only. 2 can modify, create, or delete data.

How do I enforce a policy on Mcp Rn Devtools? +

Register the Mcp Rn Devtools 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 Mcp Rn Devtools tool call.

Deterministic rules across all 19 Mcp Rn Devtools tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
