What compose-ps does on Search
AI agents call compose-ps to retrieve information from Search 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 queries and retrieves information about Docker Compose services without modifying, deleting, or executing any operations. It is a pure data retrieval operation similar to 'docker compose ps', which only displays container status. The blast radius if misused is minimal—an attacker gains visibility into container state but cannot modify infrastructure or execute commands.
From the tool's definition Tool name 'compose-ps' and description 'Lists Docker Compose services with structured state and status information' indicate a query/inspection operation.
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 Search, 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 Search, 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 Search MCP Server, which means it retrieves data without modifying state.
Register the Search 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 Search. 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 Search MCP server (Dave-London/Pare). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
