MCP

MCP is consumed by AI clients, not handwritten. Once dLazy is registered as an MCP server the tool appears in the client's tool list — Claude Code surfaces it as mcp__dlazy__fun-asr; generic clients (e.g. OpenClaw) call it as fun-asr.

See MCP setup for how to add the server.

Output

{
  "outputs": [
    { "type": "json", "id": "o_...", "value": { /* tool-specific payload */ } }
  ]
}

Structured payloads are returned as json outputs; the inner shape is tool-specific.
