## Facts

- Server: Mcp Anything (`Zaymadkid/mcp-anything`) — https://policylayer.com/tools/mcp-anything.md
- Homepage: https://github.com/Zaymadkid/mcp-anything
- 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": "session_undo",
    "arguments": {}
  }
}
```

## Why session_undo is rated Medium

Undo reverses a previous action, modifying application state. It is a reversible write-like operation (restoring prior state). It does not irreversibly delete data, execute code, or move money. Severity is medium because misuse could inadvertently reverse important user actions, but the blast radius is limited to session-level state changes.

From the tool's own definition: "Undo the last operation."

## Use case

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

## Recommended policy (PolicyLayer)

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

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