## 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 reversibly within a bounded workspace. While it can overwrite existing files, the action is reversible (files can be re-written or restored from backups), and the scope is constrained to the workspace boundary. This makes it Write rather than Destructive.

From the tool's own definition: "Tool name 'write_workspace_file' and description states it creates or overwrites files in a workspace ('在工作区中创建或覆盖写入文件'). The warning explicitly cautions about overwriting existing file content ('会覆盖已有文件内容，请谨慎使用')."

## Use case

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

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "write_workspace_file": {
      "limits": [
        {

          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
