## Facts

- Tool: `muteUser`
- Server: Xdevplatform/xmcp (`xdevplatform/xmcp`) — https://policylayer.com/tools/xdevplatform-xmcp.md
- Homepage: https://github.com/xdevplatform/xmcp
- 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": "muteUser",
    "arguments": {}
  }
}
```

## Why muteUser is rated Medium

Muting a user modifies the authenticated user's timeline/relationship settings by suppressing another user's content. This is a reversible write operation (users can be unmuted), so it falls under Write rather than Destructive. Misuse could suppress legitimate content but is not irreversible or financially impactful.

From the tool's own definition: "Mute a user to hide their posts from the authenticated user timeline"

## Use case

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