read_file

What read_file does on Mcp Control Plane

AI agents call read_file to retrieve information from Mcp Control Plane without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Why read_file is rated Low

This tool retrieves file content without side effects. The byte limit prevents excessive resource consumption. While read access to arbitrary files could expose sensitive data depending on file system permissions, the tool itself performs only a read operation with no capability to modify, delete, or execute. Risk is low unless combined with other tools or deployed without proper access controls.

From the tool's definition Tool name is 'read_file' and description states 'Read a remote file as UTF-8 text with a byte limit' — explicitly a retrieval operation with no modification, deletion, or execution capability.

The rule that runs read_file safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Mcp Control Plane, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For read_file, this is the rule to start with:

{
  "version": "1",
  "default": "deny",
  "tools": {
    "read_file": {}
  }
}
