AI agents call compose-ps to retrieve information from Python without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information about Docker Compose services and their status. The verb 'Lists' combined with 'state and status information' describes a read-only query operation with no side effects. There is no capability to create, modify, delete, execute commands, or transfer funds. The blast radius of misuse is minimal—an agent querying Docker Compose status cannot harm systems or data.
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 that retrieves and reports on existing Docker Compose service state without modification.
Attacks that exploit this kind of access
Lists Docker Compose services with structured state and status information. It is categorised as a Read tool in the Python MCP Server, which means it retrieves data without modifying state.
Register the Python 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 Python. 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 Python MCP server (Dave-London/Pare). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
compose-ps is one line of Python's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
