Read file contents
AI agents call read_file to retrieve information from Enhanced 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 file data without modifying, deleting, or executing anything. It is a straightforward read operation. Severity is low because unauthorized file access, while concerning, has limited immediate blast radius compared to write, execute, or destructive operations. Confidence is high due to the explicit and unambiguous description.
From the tool's definition Tool name is 'read_file' and description states 'Read file contents' — a pure retrieval operation with no side effects.
Attacks that exploit this kind of access
Read file contents. It is categorised as a Read tool in the Enhanced MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Enhanced 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 Enhanced 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 Enhanced MCP Server MCP server (jacobcdsmith/mcp-commander-console). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
