Validate ROOT file integrity
AI agents call validate_file to retrieve information from CERN ROOT MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
File validation is a read-only operation that inspects and reports on the state of a file without creating, modifying, deleting, or executing code. The integrity check produces diagnostics but does not alter the ROOT file or trigger external operations with unpredictable side effects. This aligns with the Read category (retrieves or queries data; no side effects).
From the tool's definition Tool is named 'validate_file' and described as 'Validate ROOT file integrity' — it performs verification/integrity checking with no modification of data or execution of arbitrary code.

Validate ROOT file integrity. It is categorised as a Read tool in the CERN ROOT MCP Server MCP Server, which means it retrieves data without modifying state.
Register the CERN ROOT MCP Server MCP server in PolicyLayer and add a rule for validate_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 CERN ROOT MCP Server. Nothing to install.
validate_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 validate_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 validate_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.
validate_file is provided by the CERN ROOT MCP Server MCP server (mohamedelashri/root-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
validate_file is one line of CERN ROOT MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
