get_diff_stats

What get_diff_stats does on Code MCP Server

AI agents call get_diff_stats to retrieve information from Code MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Why get_diff_stats is rated Low

This tool retrieves diff statistics—a form of data querying with no side effects. It computes and returns information about what changed (file count, line counts) without creating, modifying, deleting, executing, or moving resources. The read-only nature and lack of side effects place it firmly in the Read category with low severity, as misuse would only expose code change metadata, not cause harm.

From the tool's definition Tool name 'get_diff_stats' and description 'Get diff statistics (files changed, lines added/removed)' indicate a read-only query operation that retrieves and summarizes metadata about code changes without modifying data.

The rule that runs get_diff_stats safely

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

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