AI agents call read_file to retrieve information from Dev Loop without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves data (file contents) without any capability to modify, delete, or execute code. It has no side effects beyond information retrieval. The blast radius of misuse is minimal—an AI agent could read sensitive files if they exist, but cannot alter the repository state. Classified as Read with low severity.
From the tool's definition Tool name is 'read_file' and description states 'Read the contents of a file in the repository.' The verb 'read' and explicit statement of retrieving file contents with no mention of modification, deletion, or side effects confirms this is a read-only…
Attacks that exploit this kind of access
Read the contents of a file in the repository. It is categorised as a Read tool in the Dev Loop MCP Server, which means it retrieves data without modifying state.
Register the Dev Loop 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 Dev Loop. 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 Dev Loop MCP server (soynog/dev-loop-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
