## Facts

- Tool: `edit`
- Server: LocalAnt (`yuga-hashimoto/localant`) — https://policylayer.com/tools/yuga-hashimoto-localant.md
- Homepage: https://github.com/yuga-hashimoto/localant
- Risk category: Write (Medium risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no
- Parameters: 0
- Recommended policy verdict: Rate-limited

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

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

## Why edit is rated Medium

This tool creates or modifies data reversibly by replacing content in files. It is not destructive because changes are backed up and could theoretically be undone. It is not read-only as it actively rewrites file content.

From the tool's own definition: "Description states: 'Replace a unique string in a file (oldString -> newString)'. The tool modifies file contents reversibly (keeps a backup)."

Risk signals: Bulk/mass operation — affects multiple targets

## Use case

AI agents use edit to create or update resources in LocalAnt, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your LocalAnt environment.

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "edit": {
      "limits": [
        {
          "counter": "edit_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}
```
