Read the complete contents of a file from the file system as text.
AI agents call read_text_file to retrieve information from Server Everything without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Reading file contents is a non-destructive query operation that retrieves data without side effects. Severity is low because file read operations have minimal blast radius unless the file contains highly sensitive data, but the tool itself has no harmful capability.
From the tool's definition Tool name is 'read_text_file' and description states it 'Read the complete contents of a file from the file system as text.' This is a straightforward read operation with no modification, deletion, or execution capability.
Attacks that exploit this kind of access
Read the complete contents of a file from the file system as text. It is categorised as a Read tool in the Server Everything MCP Server, which means it retrieves data without modifying state.
Register the Server Everything MCP server in PolicyLayer and add a rule for read_text_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 Server Everything. Nothing to install.
read_text_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_text_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_text_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_text_file is provided by the Server Everything MCP server (@modelcontextprotocol/server-everything). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
