A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

An MCP (Model Context Protocol) server for Draw Things - enabling LLMs to generate images locally on Mac using Stable Diffusion and other AI models.
Verify the server is running:
curl http://localhost:7860#### Claude Desktop
Add to ~/Library/Application Support/Claude/claude_desktop_config.json:
{
"mcpServers": {
"drawthings": {
"command": "npx",
"args": ["-y", "mcp-drawthings"]
}
}
}#### Cursor
Add to .cursor/mcp.json in your project or global config:
{
"mcpServers": {
"drawthings": {
"command": "npx",
"args": ["-y", "mcp-drawthings"]
}
}
}Restart Claude Desktop or Cursor to load the new MCP server.
