What docker_volumes does on Yaver
AI agents call docker_volumes to retrieve information from Yaver without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why docker_volumes is rated Low
This tool performs a read-only operation to list existing Docker volumes. It has no side effects, does not execute code or commands, does not modify data, and does not delete or move resources. The blast radius of misuse is minimal—an agent could learn about available volumes but cannot harm infrastructure with this tool alone.
From the tool's definition Tool name 'docker_volumes' and description 'List Docker volumes' indicate a query operation that retrieves information about Docker volumes without modification or execution.
Attacks that exploit this kind of access
The rule that runs docker_volumes safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Yaver, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For docker_volumes, this is the rule to start with:
docker_volumes is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Yaver, apply this rule, and every docker_volumes call is checked against it from then on.
Questions about docker_volumes
List Docker volumes. It is categorised as a Read tool in the Yaver MCP Server, which means it retrieves data without modifying state.
Register the Yaver MCP server in PolicyLayer and add a rule for docker_volumes: 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 Yaver. Nothing to install.
docker_volumes is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the docker_volumes 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.
Set action: deny in the PolicyLayer policy for docker_volumes. 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.
docker_volumes is provided by the Yaver MCP server (yaver-cli). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
