## Facts

- Tool: `learn`
- Server: PromptX (`deepractice/promptx`) — https://policylayer.com/tools/deepractice-promptx.md
- Homepage: https://github.com/Deepractice/PromptX
- Risk category: Read (Low risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no
- Parameters: 0
- Recommended policy verdict: Allowed

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "learn",
    "arguments": {}
  }
}
```

## Why learn is rated Low

This tool retrieves and loads professional resources for AI agents to reference. It has no side effects—it only reads data from PromptX resources using a protocol URL. This is a straightforward Read operation with minimal risk, as it cannot modify system state or execute arbitrary code.

From the tool's own definition: "Tool name 'learn' and description 'Load and learn PromptX resources by protocol URL' indicate data retrieval operations. The verb 'load' and 'learn' are passive consumption of resources (role definitions, thinking models, knowledge bases, tool manuals)."

## Use case

AI agents call learn to retrieve information from PromptX without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "learn": {}
  }
}
```
