Autonomous, edge-native micro-commerce engines providing deterministic media geometry, structural calculations, and node-graph preflight audits. Every engine is monetized natively via the **x402 payment protocol** on **Base Mainnet**, allowing autonomous AI agents to discover, call, and settle computations in native USDC without human intermediation.

## Model Context Protocol (MCP) Integration

Ligeia Studio engines expose a standardized **Model Context Protocol (MCP)** server (`ligeia_mcp_server.py`) for plug-and-play integration with Claude Desktop, Cursor, Cline, and autonomous agent frameworks.

### Installation via Smithery
```bash
npx -y @smithery/cli install ligeia-mcp-server
```
