Get dependencies, devDependencies, and peerDependencies for a package
AI agents call get_package_dependencies to retrieve information from NPM Context Agent MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns dependency information about npm packages. It has no side effects, does not modify data, execute code, or trigger external operations. It is a straightforward read operation that fits the 'Read' category—data retrieval with no ability to alter system state.
From the tool's definition Tool retrieves package dependency metadata (dependencies, devDependencies, peerDependencies). The description indicates pure information retrieval with no modification, creation, deletion, or execution capabilities.
Attacks that exploit this kind of access
Get dependencies, devDependencies, and peerDependencies for a package. It is categorised as a Read tool in the NPM Context Agent MCP MCP Server, which means it retrieves data without modifying state.
Register the NPM Context Agent MCP server in PolicyLayer and add a rule for get_package_dependencies: 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 Context Agent MCP. Nothing to install.
get_package_dependencies 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 get_package_dependencies 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 get_package_dependencies. 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.
get_package_dependencies is provided by the NPM Context Agent MCP server (juansebastiangb/npm-context-agent-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
