Start the Model Context Protocol server for the current Caravela project on stdio.

mix caravela.mcp

Intended to be launched by an MCP host (Claude Code, Cursor, Zed, etc.) that owns the process's stdin/stdout. Runs until stdin closes.

Configuring a host

Claude Code ~/.claude/claude_desktop_config.json:

{
  "mcpServers": {
    "caravela": {
      "command": "mix",
      "args": ["caravela.mcp"],
      "cwd": "/absolute/path/to/your/phoenix/project"
    }
  }
}

Equivalent entries work for Cursor, Zed, and any other MCP-speaking host.

What the host can do

Once connected, the host exposes these tools to the LLM:

  • caravela__describe_domain — full IR for a domain module
  • caravela__list_entities — entity names in a domain
  • caravela__describe_entity — IR for one entity
  • caravela__validate_dsl — compile a candidate DSL and report structured errors

See Caravela.MCP for the full tool list and wire format.
