name: myapp
description: Interact with MyApp. Use this skill to [describe what agents can do]. Requires ATXP authentication.
---
 
# MyApp
 
[Brief description] at **https://your-domain.com**
 
## Quick Start
 
1. Install ATXP: `npx skills add atxp-dev/cli --skill atxp`
2. Call MCP tools: `npx atxp-call https://your-domain.com/mcp <tool> [params]`
 
## Authentication
 
Get a cookie for browser use:
 
\`\`\`bash
npx atxp-call https://your-domain.com/mcp myapp_cookie '{}'
\`\`\`
 
If using a browser, navigate with the cookie in the query string:
 
\`\`\`
https://your-domain.com?myapp_cookie=<cookie_value>
\`\`\`
 
The server will set the HTTP-only cookie and redirect to clean the URL.
 
**Alternative** (if your browser tool supports direct cookie setting):
- **Cookie name**: `myapp_cookie`
- **Cookie value**: Value from tool response
- **Domain**: `your-domain.com`
- **Path**: `/`
- **HttpOnly**: `true`
 
## MCP Tools
 
| Tool | Description | Cost |
|------|-------------|------|
| `myapp_cookie` | Get auth cookie | Free |
| `myapp_action` | Perform action | $0.10 |
