Read the contents of a file
AI agents call read_file to retrieve information from README Generator 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 and queries file contents without causing side effects. It is a pure read operation consistent with the Read category. Severity is low because reading project files in the context of a README generator poses minimal risk—the tool cannot modify, delete, or execute code. Confidence is high due to the explicit and unambiguous nature of the description.
From the tool's definition Tool name: read_file. Tool description: 'Read the contents of a file'. No modification, deletion, or execution occurs.
Attacks that exploit this kind of access
Read the contents of a file. It is categorised as a Read tool in the README Generator MCP Server MCP Server, which means it retrieves data without modifying state.
Register the README Generator MCP Server MCP server in PolicyLayer and add a rule for read_file: 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 README Generator MCP Server. Nothing to install.
read_file 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 read_file 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 read_file. 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.
read_file is provided by the README Generator MCP Server MCP server (jojoslice/readme-gen-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
