# MCP Server

Built-in [Model Context Protocol](https://modelcontextprotocol.io/) server. Run SLANG workflows from any MCP-compatible host — no API key needed, the host's LLM does the work.

```bash
claude mcp add slang -- npx --package @riktar/slang slang-mcp
```

## Tools

| `parse_flow` | Parse source to AST JSON |
| `check_flow` | Dependency graph + deadlock detection + diagnostics |
