inspect_files · Elasticsearch Knowledge Graph for MCP

WHAT IT DOES

What inspect_files does on Elasticsearch Knowledge Graph for MCP

AI agents call inspect_files to retrieve information from Elasticsearch Knowledge Graph for MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

THE RISK

Low Risk

Why inspect_files needs a policy

This tool retrieves and queries file content without creating, modifying, or deleting data. The verb 'retrieve' and 'inspection' are passive operations. While it operates on files, it has no side effects and does not execute external commands or alter state. The low severity reflects minimal risk even if misused by an AI agent—worst case is exposure of existing data rather than data loss or external actions.

From the tool's definition Tool name 'inspect_files' and description 'Agent driven file inspection that uses AI to retrieve relevant content from multiple files' indicates data retrieval with no modification or deletion capabilities.

POLICY

How to control inspect_files

PolicyLayer is an MCP gateway — it sits between your AI agents and Elasticsearch Knowledge Graph for MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for inspect_files:

policy.json

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

inspect_files is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
