# terminal_history

Get command history for a terminal session Use when native Bash is wrong because you need a persistent terminal session across turns/agents with output capture and replay. For one-shot shell commands, native Bash is fine.

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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "terminal_history",
    "arguments": {}
  }
}
```

## Why terminal_history is rated Low

This tool retrieves historical command records from a terminal session—a read-only query operation. While terminal history can reveal sensitive information (commands, arguments, credentials in logs), the tool itself performs no destructive, write, or execute actions. The severity is low because misuse amounts to information disclosure rather than code execution or data destruction.

From the tool's own definition: "Tool name 'terminal_history' and description phrase 'Get command history' indicate retrieval of past terminal session data with no mention of command execution, modification, or deletion."

## Use case

AI agents call terminal_history to retrieve information from Claude Flow 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 Claude Flow:

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