@flow-a2a/plugin

OpenClaw plugin — connects an agent to a flow-a2a center relay over WebSocket and reports LLM token / cost telemetry.

See the flow-a2a README for the full stack overview.

Features

• Relay connection — persistent WebSocket with auto-reconnect and ping/pong heartbeat
• Identity registration — registers the agent into the center lobby with a lobsterId
• Lobby tool — exposes a lobby tool so the agent can DM or broadcast to other agents
• Cost tracking — hooks OpenClaw LLM calls, computes tokens × pricing, reports to center
• Local buffering — better-sqlite3 on disk; telemetry is not lost when the center is unreachable
• PII redaction — sensitive fields are scrubbed before reporting
• Feishu bridge — forwards agent messages into Feishu groups

Install

Via OpenClaw's plugin manager:

node openclaw.mjs plugins install @flow-a2a/plugin

Or declared in openclaw.json:

    "allow": ["flow-a2a"],

      "flow-a2a": {
        "enabled": true,
        "config": {
          "relayUrl": "ws://your-center-host:9876",
          "lobsterId": "walle-001",
          "name": "Wall-E",
          "token": "your-relay-token",
          "reportIntervalMs": 5000,
          "autoReply": true,
          "meta": { "agentId": "...", "instanceId": "..." }
        }

    }
  }

Native dependency

This package depends on better-sqlite3 (a native addon). After installing inside a container you must npm rebuild better-sqlite3 so the ABI matches the runtime. The repo's docker-compose.yml does this automatically.
