MOST DANGEROUS TOOLS

High Risk

The most dangerous Shell Executor MCP Server tools

Execute · High execute_command Shell command execution is Execute category because it triggers external operations whose effects depend on arguments and runtime state. Execute · Medium streamline_python_imports This tool modifies Python source files by reorganizing import statements, which constitutes a Write action at minimum. Write · Medium add_comments The tool creates or modifies code content reversibly by inserting comments and documentation. Write · Medium generate_tests This tool generates unit test code, which is a Write operation — it creates new content (test files/code).

5 of Shell Executor MCP Server's 12 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Shell Executor MCP Server

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

Rate limit write operations

{
  "add_comments": {
    "limits": [
      {
        "counter": "add_comments_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "analyze_code": {
    "limits": [
      {
        "counter": "analyze_code_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

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

FAQ

Questions about Shell Executor MCP Server

How do I prevent bulk modifications through Shell Executor MCP Server? +

The Shell Executor MCP Server server has 3 write tools including add_comments, generate_tests, streamline_rust_imports. 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 Shell Executor MCP Server.

How many tools does the Shell Executor MCP Server MCP server expose? +

12 tools across 3 categories: Execute, Read, Write. 7 are read-only. 5 can modify, create, or delete data.

How do I enforce a policy on Shell Executor MCP Server? +

Register the Shell Executor MCP Server 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 Shell Executor MCP Server tool call.

Deterministic rules across all 12 Shell Executor MCP Server tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
