What label-list does on Npm
AI agents call label-list 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 label-list is rated Low
This tool only queries and returns information about existing repository labels. It performs no creation, modification, deletion, or execution operations. The blast radius of misuse is minimal—an agent could only over-retrieve label data. Classification as Read is appropriate.
From the tool's definition Tool name 'label-list' and description 'Lists repository labels' indicate a retrieval operation with no side effects. Returns structured data (label name, description, color, default status) without modification.
Attacks that exploit this kind of access
The rule that runs label-list 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 label-list, this is the rule to start with:
label-list 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 label-list call is checked against it from then on.
Questions about label-list
Lists repository labels. Returns structured data with label name, description, color, and default status. 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 label-list: 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.
label-list 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 label-list 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 label-list. 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.
label-list 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.
