## Facts

- Tool: `role.assign`
- Server: Visionmcp (`joshuahickscorp/visionmcp`) — https://policylayer.com/tools/visionmcp.md
- Homepage: https://github.com/joshuahickscorp/visionmcp
- 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": "role.assign",
    "arguments": {}
  }
}
```

## Why role.assign is rated Medium

The tool assigns persistent roles, which constitutes creating or modifying data. This is a Write-category operation because assignments can typically be changed or revoked. Severity is medium because incorrect role assignments could affect access control or task distribution, but the effect is limited to advisory roles rather than system-critical permissions.

From the tool's own definition: "Tool name 'assign' and description 'Assign one persistent advisory role task' indicate creation/modification of role assignments, which is reversible data creation (not deletion, not financial, not code execution)."

## Use case

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

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "role.assign": {
      "limits": [
        {
          "counter": "role.assign_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}
```
