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

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

## Why wa_mute_chat is rated Medium

Muting/unmuting a chat modifies user preferences and notification state but does not create, delete, or irreversibly alter data. The action is entirely reversible (can be unmuted), has minimal blast radius, and does not execute code or move money. This classifies as Write rather than Read (since it modifies state) or more severe categories.

From the tool's own definition: "Tool name 'wa_mute_chat' and description 'Mute or unmute a chat' indicate state modification without data destruction. The optional 'muteUntil' parameter accepts a Unix timestamp, confirming this modifies chat notification settings reversibly."

## Use case

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

## Recommended policy (PolicyLayer)

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

```json
