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

```json
{
  "jsonrpc": "2.0",

  "params": {
    "name": "vikunja_users",

## Why vikunja_users is rated Medium

The tool performs user profile and settings updates, which are Write operations that modify data reversibly. Severity is high because user account modifications (profiles, settings) can affect authentication, permissions, and user experience across the system, creating significant blast radius if an AI agent misuses it to alter unauthorized user accounts or settings.

From the tool's own definition: "Tool description states 'Manage user profiles' and 'update user settings' — these are modification operations. The term 'manage' combined with 'update' indicates reversible data mutation."

## Use case

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