bee-agent 0.3.0

QueenBee and WorkerBee for CommandHive.xyz

Overview

This is agent orchestrator backend to create agents on fly, store all your MCP variables and get tasks done round the clock from these agents. Visit CommandHive Website

✅ Completed

• Ensure sampling as MCP feature is working
• Create Pub/Sub support using Redis
• Create Pub/Sub support using Kafka
• Create Pub/Sub support using MSK (Managed Kafka)
• Ensure tool calling is done with confirmation
• Check compatibility with Python 3.11
• Check compatibility with Python 3.12

⏳ To Do Next

• Integrate smart contract for tool calling
• Each agent has its own wallet (defined in config)
• Pub/Sub support for RabbitMQ
• Pub/Sub support for Google Pub/Sub
