WHAT IT DOES

What volume-ls does on Github

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

RISK

Why volume-ls is rated Low

This tool retrieves and displays information about Docker volumes (driver, mountpoint, scope details) without creating, modifying, deleting, or executing anything. It is a pure read operation with minimal risk—an agent querying it gains only informational access to the container environment's volume configuration.

From the tool's definition Tool name 'volume-ls' and description 'Lists Docker volumes' indicate a query/listing operation with no modification or side effects.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs volume-ls safely

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

volume-ls Allowed

volume-ls 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": {
    "volume-ls": {}
  }
}

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

The button opens the PolicyLayer dashboard: create your workspace, connect Github, apply this rule, and every volume-ls call is checked against it from then on.

FAQ

Questions about volume-ls

What does the volume-ls tool do? +

Lists Docker volumes with structured driver, mountpoint, and scope information. It is categorised as a Read tool in the Github MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on volume-ls? +

Register the Github MCP server in PolicyLayer and add a rule for volume-ls: 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 Github. Nothing to install.

What risk level is volume-ls? +

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

Can I rate-limit volume-ls? +

Yes. Add a rate_limit block to the volume-ls 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 volume-ls completely? +

Set action: deny in the PolicyLayer policy for volume-ls. 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 volume-ls? +

volume-ls is provided by the Github MCP server (@paretools/github). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
