Detect which package manager is used in the project (npm, yarn, pnpm).
AI agents call web_detect_package_manager to retrieve information from PC-Control MCP Server 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 the project's package manager configuration (npm, yarn, pnpm). It performs passive detection—reading project files or metadata to determine which package manager is in use. There are no side effects, no code execution, no data modification, and no irreversible actions. This is a straightforward Read operation.
From the tool's definition Tool name 'web_detect_package_manager' and description 'Detect which package manager is used in the project' indicate inspection/querying of project configuration without modifying or executing anything.
Attacks that exploit this kind of access
Detect which package manager is used in the project (npm, yarn, pnpm). It is categorised as a Read tool in the PC-Control MCP Server MCP Server, which means it retrieves data without modifying state.
Register the PC-Control MCP Server MCP server in PolicyLayer and add a rule for web_detect_package_manager: 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 PC-Control MCP Server. Nothing to install.
web_detect_package_manager 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 web_detect_package_manager 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 web_detect_package_manager. 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.
web_detect_package_manager is provided by the PC-Control MCP Server MCP server (krsnmlna1/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
