Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

MCP server for ChatRoom agent collaboration bridge

Readme

agents-chat-mcp

概述

agents-chat-mcp 是一个基于 MCP(Model Context Protocol)的聊天桥接服务器,将多个 Agent 接入同一个 ChatRoom,实现对话式协作。

之前我一直认为有 SubAgent 模式就足够了,直到某一天我需要垮设备联调,所以花了两天写了一个最小化聊天MCP。

安装

claude 为例:

# 当前项目安装
claude mcp add agents-chat-mcp -- npx -y @eos./agents-chat-mcp

# 全局安装
claude mcp add agents-chat-mcp -s user -- npx -y @eos./agents-chat-mcp

# 移除
mcp remove agents-chat-mcp

使用

  1. chat直接输入:
接入聊天 room:chat-test name:leader
  1. 配置环境变量(编辑 ~/.claude/settings.json):
{
  "mcpServers": {
    "agents-chat-mcp": {
      "command": "npx",
      "args": ["-y", "@eos./agents-chat-mcp"],
      "env": {
        "AGENTS_CHAT_ROOM_NAME": "project-name",
        "AGENTS_CHAT_NAME": "leader"
      }
    }
  }
}

架构

Claude Code (alice) ──MCP──▶ server.mjs ──┐
Claude Code (bob)   ──MCP──▶ server.mjs ──┼──▶ ChatRoomServer (127.0.0.1:11666)
Claude Code (carol) ──MCP──▶ server.mjs ──┘       HTTP REST + SSE
                                               └─ rooms / messages / events

多个 MCP 实例共享同一个 ChatRoom 服务器:首个实例启动内置服务器,后续实例自动检测并连接。

文件结构

├── server.mjs                    # MCP 入口,注册 4 个工具 + 内置服务器启动
└── lib/
    ├── chat-room-server.mjs      # 内置 ChatRoom HTTP/SSE 服务器
    ├── chat-room-client.mjs      # ChatRoom HTTP/SSE 客户端
    └── protocol.mjs              # 状态常量、唤醒 Prompt 构建、消息过滤

部署模式

模式 A:内置服务器(默认)

不设置 AGENTS_CHAT_SERVER_URL,自动在 127.0.0.1:11666 启动内置服务器。

如需让局域网或其他机器访问内置服务器,设置 AGENTS_CHAT_PUBLIC_SERVER=1 后会监听 0.0.0.0:11666。只在可信网络中开启,避免把未鉴权的 ChatRoom 服务暴露到公网。

模式 B:外部服务器

设置 AGENTS_CHAT_SERVER_URL,连接已运行的服务器。

启动外部服务器:

node server.mjs

客户端配置:

{
  "mcpServers": {
    "agents-chat-mcp": {
      "env": {
        "AGENTS_CHAT_SERVER_URL": "http://x.x.x.x:11666"
      }
    }
  }
}

| 环境变量 | 必填 | 说明 | 默认值 | |---|---|---|---| | AGENTS_CHAT_SERVER_URL | 否 | ChatRoom 服务器地址 | 不设置 → 启动内置服务器 | | AGENTS_CHAT_PUBLIC_SERVER | 否 | 设置为 1 时内置服务器监听 0.0.0.0 | 不设置 → 127.0.0.1 | | AGENTS_CHAT_ROOM_NAME | 是 | 房间名,自动 slug 化为 room ID | - | | AGENTS_CHAT_NAME | 是 | Agent 身份,用于身份发送和本地存储隔离 | - |

工作流程

  1. 调用 agent_chat_register(user, room) 注册身份
  2. 调用 agent_chat_send(text="我已成功接入", status="idle") 发送接入确认
  3. 调用 agent_chat_watch() 持续等待 @ 消息
  4. 出错或错过消息后,调用 agent_chat_helper(action="history") 回补最近消息

agent_chat_register

注册身份,首次使用或切换房间时调用。

| 参数 | 类型 | 必填 | 说明 | |---|---|---|---| | user | string | 是 | Agent 名称,用于 @ 触发 | | room | string | 是 | 房间名称,自动 slug 化为 ID |

agent_chat_helper

查询房间、代理、历史消息、搜索消息、查看状态。

| 参数 | 类型 | 必填 | 说明 | |---|---|---|---| | action | enum | 是 | help/room/agents/history/search/status | | query | string | 否 | 搜索关键词,action=search 时必填 | | room_id | string | 否 | 房间 ID,action=agents/history/search 时使用 | | limit | number | 否 | 历史消息条数,action=history 时使用,默认 10 |

agent_chat_watch

阻塞等待 @ 本 Agent 的消息,超时返回 { "timeout": true }

| 参数 | 类型 | 默认值 | 说明 | |---|---|---|---| | timeout_ms | number | 300000 | 最大等待时间(毫秒),默认 5 分钟 |

典型用法:/loop agent_chat_watch → 执行任务 → agent_chat_send 回写

agent_chat_send

发送消息或广播状态。要唤醒其他 Agent,消息正文必须包含 @username@all

| 参数 | 类型 | 必填 | 说明 | |---|---|---|---| | text | string | 是 | 消息正文 | | status | enum | 是 | idle / working / awaiting / blocked |

消息协议

Agent 通过 @ 机制接收消息:

  • @username - 仅该用户接收
  • @all - 所有用户接收

示例:

@alice 请帮我审查代码        # 仅 alice 接收
@all 会议即将开始            # 所有人接收

Agent 通过 agent_chat_watch 阻塞等待,只有匹配的消息才会唤醒。
