# toolx

ToolX runtime — load and execute PromptX ecosystem tools What It Does Universal interface for calling PromptX tools (file ops, PDF reading, role creation, etc.). Input is a YAML document specifying the tool, mode, and parameters. Modes | Mode | Purpose | |---|---| | manual | Read tool documentation (always do this first) | | execute | Run the tool with parameters | | configure | Set environment variables for a tool | | log | View tool execution logs | | dryrun | Preview without executing | Examples Read tool manual (do this first): \

## Facts

- Tool: `toolx`
- Server: PromptX (`deepractice/promptx`) — https://policylayer.com/tools/deepractice-promptx.md
- Homepage: https://github.com/Deepractice/PromptX
- Risk category: Execute (High 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": "toolx",
    "arguments": {}
  }
}
```

## Why toolx is rated High

toolx is a meta-tool that executes other PromptX tools based on YAML input. While it includes safe modes (manual, log, dryrun), the execute mode runs arbitrary tools from the ecosystem with user-specified parameters. The sibling tools span Read, Write, and Destructive categories; toolx's capacity to invoke them means misuse could delete workspaces, modify files, or execute code.

From the tool's own definition: "'Universal interface for calling PromptX tools' with 'execute' mode to 'Run the tool with parameters'; ecosystem includes destructive tools (delete_workspace_item) and file operations; YAML-based arbitrary tool invocation enables execution of sibling tools…"

## Use case

AI agents invoke toolx to trigger actions in PromptX. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

## 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": {
    "toolx": {
      "limits": [
        {
          "counter": "toolx_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}
```
