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

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

## Why bisect is rated High

bisect runs git bisect operations, executing version control commands to navigate commit history. It triggers external operations (checking out commits, running tests) whose effects depend on the repository state and arguments. While it doesn't permanently delete data, it does execute external processes and can modify working tree state.

From the tool's own definition: "Binary search for the commit that introduced a bug... action taken, current commit, remaining steps estimate"

## Use case

AI agents invoke bisect to trigger actions in Go. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Go:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "bisect": {
      "limits": [
        {
          "counter": "bisect_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}
```
