Redo the last undone editor action.

Agent View of the PolicyLayer registry record for `redo`. HTML page: https://policylayer.com/tools/quangdang46-uefn-verse-mcp/redo

## Facts

- Tool: `redo`
- Server: Uefn (`quangdang46/uefn-verse-mcp`) — https://policylayer.com/tools/quangdang46-uefn-verse-mcp.md
- Homepage: https://github.com/quangdang46/uefn-verse-mcp
- 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": "redo",
    "arguments": {}
  }
}
```

## Why redo is rated Medium

Redo re-applies a previously undone modification to the editor state, which is a write/modify operation. It is reversible (can be undone again), so it doesn't qualify as Destructive. The blast radius is medium since it could reapply arbitrary editor changes depending on what was undone.

From the tool's own definition: "Redo the last undone editor action"

## Use case

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

## Recommended policy (PolicyLayer)

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

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