Read a file
AI agents call read_file to retrieve information from Scratchpad without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves file contents without altering data, executing code, or triggering external operations. It is a straightforward read operation with minimal risk of misuse.
From the tool's definition Tool name 'read_file' and description 'Read a file' indicate data retrieval with no modification or side effects.
Attacks that exploit this kind of access
Read a file. It is categorised as a Read tool in the Scratchpad MCP Server, which means it retrieves data without modifying state.
Register the Scratchpad 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 Scratchpad. 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 Scratchpad MCP server (mikepressure/scratchpad-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
