## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",

## Why get_file_ledger is rated Low

This tool retrieves and queries a change ledger for a specific file. It produces no side effects, does not modify data, and does not execute code or delete anything. It is purely informational, helping an AI understand version history before making changes. The low severity reflects minimal blast radius — an agent could only access metadata about past changes.

From the tool's own definition: "Tool description states 'Get all logged changes that touched a specific file path' — uses 'Get' and 'logged changes', indicating retrieval of historical data with no modification or deletion."

## Use case

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

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Mcp Dev:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_file_ledger": {}
  }
}
```
