## Facts

- Tool: `write_workspace_file`
- Server: Nodebench (`nodebench-mcp`) — https://policylayer.com/tools/io-github-homenshum-nodebench.md
- Install: `npx -y nodebench-mcp`
- Homepage: https://github.com/HomenShum/nodebench-ai
- 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": "write_workspace_file",
    "arguments": {}
  }
}
```

## Why write_workspace_file is rated Medium

This tool creates or modifies files in a local workspace directory. It is reversible (files can be edited or deleted), so it does not qualify as Destructive. It performs data modification without executing arbitrary code or triggering external operations, so it is Write rather than Execute.

From the tool's own definition: "Tool description explicitly states 'Create or update a file' which are write operations. The workspace path (~/.nodebench/workspace/) indicates local filesystem modification."

## Use case

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

## Recommended policy (PolicyLayer)

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

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