What compose-ps does on Go
AI agents call compose-ps to retrieve information from Go without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why compose-ps is rated Low
This tool only retrieves and displays the current state of Docker Compose services. It performs no modifications, deletions, code execution, or financial operations. It is a straightforward query operation with minimal blast radius—the worst case is returning stale or inaccurate status information, which does not affect system state.
From the tool's definition Tool name is 'compose-ps' and description states it 'Lists Docker Compose services with structured state and status information.' The verb 'Lists' and the read-only nature of querying service status indicates pure information retrieval with no side effects.
Attacks that exploit this kind of access
The rule that runs compose-ps safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Go, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For compose-ps, this is the rule to start with:
compose-ps 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 Go, apply this rule, and every compose-ps call is checked against it from then on.
Questions about compose-ps
Lists Docker Compose services with structured state and status information. It is categorised as a Read tool in the Go MCP Server, which means it retrieves data without modifying state.
Register the Go MCP server in PolicyLayer and add a rule for compose-ps: 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 Go. Nothing to install.
compose-ps 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 compose-ps 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 compose-ps. 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.
compose-ps is provided by the Go MCP server (Dave-London/Pare). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
