WHAT IT DOES

What filesystem_list does on Godot Breakpoint

AI agents call filesystem_list to retrieve information from Godot Breakpoint without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why filesystem_list is rated Low

This tool retrieves and queries the structure of the project filesystem without creating, modifying, deleting, or executing any operations. It has no side effects and poses minimal security risk, making it a straightforward Read category classification with low severity.

From the tool's definition Tool explicitly described as 'List the subdirectories and files of a directory in the project filesystem' and marked 'Read-only.' The name 'filesystem_list' and action of listing directory contents with no modification capability confirm retrieval-only…

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs filesystem_list safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Godot Breakpoint, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For filesystem_list, this is the rule to start with:

filesystem_list Allowed

filesystem_list is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "filesystem_list": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Godot Breakpoint, apply this rule, and every filesystem_list call is checked against it from then on.

FAQ

Questions about filesystem_list

What does the filesystem_list tool do? +

List the subdirectories and files of a directory in the project filesystem (hidden entries like .godot are skipped). Read-only. It is categorised as a Read tool in the Godot Breakpoint MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on filesystem_list? +

Register the Godot Breakpoint MCP server in PolicyLayer and add a rule for filesystem_list: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Godot Breakpoint. Nothing to install.

What risk level is filesystem_list? +

filesystem_list is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit filesystem_list? +

Yes. Add a rate_limit block to the filesystem_list rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block filesystem_list completely? +

Set action: deny in the PolicyLayer policy for filesystem_list. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides filesystem_list? +

filesystem_list is provided by the Godot Breakpoint MCP server (jlivingston-Cipher/godot-breakpoint-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
