What compose-ps does on Git
AI agents call compose-ps to retrieve information from Git 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 performs a read-only operation that queries the status of Docker Compose services. It retrieves information about running containers and their states but does not create, modify, delete, or execute any operations. The output is informational only, with no side effects on the system.
From the tool's definition Tool name 'compose-ps' and description 'Lists Docker Compose services with structured state and status information' indicate a query operation that retrieves and displays container status without modifying any state.
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 Git, 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 Git, 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 Git MCP Server, which means it retrieves data without modifying state.
Register the Git 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 Git. 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 Git MCP server (Dave-London/Pare). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
