What inspect does on Npm
AI agents call inspect to retrieve information from Npm without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why inspect is rated Low
The inspect tool performs information retrieval on containers or images. It gathers and returns structured data about existing resources (state, image metadata, platform details) without creating, modifying, deleting, or executing operations. This is a classic Read category operation with low severity since it has no side effects and poses minimal risk if misused by an agent.
From the tool's definition Tool name 'inspect' combined with description 'Shows detailed container or image information with structured state, image, and platform data' indicates a read-only query operation that retrieves and displays information without modifying state.
Attacks that exploit this kind of access
The rule that runs inspect safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Npm, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For inspect, this is the rule to start with:
inspect 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 Npm, apply this rule, and every inspect call is checked against it from then on.
Questions about inspect
Shows detailed container or image information with structured state, image, and platform data. It is categorised as a Read tool in the Npm MCP Server, which means it retrieves data without modifying state.
Register the Npm MCP server in PolicyLayer and add a rule for inspect: 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 Npm. Nothing to install.
inspect 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 inspect 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 inspect. 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.
inspect is provided by the Npm MCP server (Dave-London/Pare). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
