Get README file content from a package
AI agents call get_readme_data 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 retrieves static documentation content (README files) from npm packages. It has no side effects, does not execute code, does not modify data, and does not delete or move resources. The operation is purely informational and aligns with the Read category for data retrieval operations.
From the tool's definition Tool name 'get_readme_data' and description 'Get README file content from a package' indicate retrieval of package documentation without modification. This is a read-only operation that queries and returns existing data (README files) from the npm ecosystem.
Attacks that exploit this kind of access
Get README file content from 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_readme_data: 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_readme_data 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_readme_data 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_readme_data. 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_readme_data 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.
