### Description (declared)

# call-a-human-mcp

Your AI agent is about to delete the production database. Do you want it to just go ahead?

**call-a-human-mcp** is an MCP server that gives any AI agent a pause button — it can ask you a question or request your approval before taking action, and it won't proceed until you respond.

```
Claude:  request_approval("Drop table users_backup — 2.1GB, irreversible")

Slack:   ⚠️  AI Agent requesting approval
         Action: Drop table users_backup — 2.1GB, irreversible
         [Approve]  [Deny]
                              ← you click Deny
Claude:  "Understood, skipping the deletion."
```

Works with Claude Desktop, Cursor, Windsurf, and any MCP-compatible agent. Notifications via Slack, Telegram, or macOS system dialogs.

Two tools:

| Tool | When to use | Returns |
|------|-------------|---------|
| `ask_human(question, context?)` | Need information only a human can provide | `str` — human's text reply |
| `request_approval(action, details?)` | Before any irreversible action | `{"approved": bool, "reason": str}` |

The tool call **blocks** until you respond (or the timeout expires).
