What pip-show does on Cargo
AI agents call pip-show to retrieve information from Cargo without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why pip-show is rated Low
The tool queries package information from the Python environment and returns metadata without side effects. It does not modify packages, execute code, delete resources, or perform financial operations. This is a straightforward read operation.
From the tool's definition Tool performs 'pip show' which retrieves and returns structured package metadata (name, version, summary, dependencies) with no modification or execution of code.
Attacks that exploit this kind of access
The rule that runs pip-show safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Cargo, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For pip-show, this is the rule to start with:
pip-show 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 Cargo, apply this rule, and every pip-show call is checked against it from then on.
Questions about pip-show
Runs pip show and returns structured package metadata (name, version, summary, dependencies). It is categorised as a Read tool in the Cargo MCP Server, which means it retrieves data without modifying state.
Register the Cargo MCP server in PolicyLayer and add a rule for pip-show: 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 Cargo. Nothing to install.
pip-show 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 pip-show 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 pip-show. 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.
pip-show is provided by the Cargo MCP server (Dave-London/Pare). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
