MOST DANGEROUS TOOLS

Critical Risk

The most dangerous BetterMCPFileServer tools

Destructive · High manageFile The tool explicitly supports deleting files, which is irreversible. Destructive · High manageFolder Because this tool supports destructive operations (deleting a folder and presumably all its contents), it must be classified at the highest applicable severity. Write · High editFile This tool modifies existing file content through targeted edits rather than full rewrites. Write · High writeFile The tool creates new files or modifies existing files, which are reversible operations.

4 of BetterMCPFileServer'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 BetterMCPFileServer

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

Deny destructive operations

{
  "manageFile": {
    "deny_if": [
      {
        "conditions": [],
        "on_deny": "Blocked by default. Requires approval."
      }
    ]
  }
}

Destructive tools should never be available to autonomous agents without human approval.

Rate limit write operations

{
  "editFile": {
    "limits": [
      {
        "counter": "editfile_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "readFileContent": {
    "limits": [
      {
        "counter": "readfilecontent_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 BetterMCPFileServer — 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.

Can an AI agent delete data through the BetterMCPFileServer MCP server? +

Yes. The BetterMCPFileServer server exposes 2 destructive tools including manageFile, manageFolder. These permanently remove resources with no undo. PolicyLayer blocks destructive tools by default so they never reach the upstream server.

How do I prevent bulk modifications through BetterMCPFileServer? +

The BetterMCPFileServer server has 2 write tools including editFile, writeFile. 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 BetterMCPFileServer.

How many tools does the BetterMCPFileServer MCP server expose? +

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

How do I enforce a policy on BetterMCPFileServer? +

Register the BetterMCPFileServer 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 BetterMCPFileServer tool call.

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