PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Computer or cloud
  • Transport: stdio, Streamable HTTP
  • Category: Other
  • You need to fill in: Authorization

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 2 of 2 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • You fill in yourself: Authorization

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

  • Runs in the cloudNothing to install; it connects over the internet
  • npmNode.js installed (for the npx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Or run it on your computer

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "canvas": {
      "command": "npx",
      "args": [
        "-y",
        "@avatargaia/canvas-mcp"
      ]
    }
  }
}

Run this in your terminal

claude mcp add --transport http canvas https://agent.avatargaia.top/api/mcp/canvas --header 'Authorization: your-value'

Or run it on your computer

claude mcp add canvas -- npx -y @avatargaia/canvas-mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "canvas": {
      "url": "https://agent.avatargaia.top/api/mcp/canvas",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

Or run it on your computer

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "canvas": {
      "command": "npx",
      "args": [
        "-y",
        "@avatargaia/canvas-mcp"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "canvas": {
      "type": "http",
      "url": "https://agent.avatargaia.top/api/mcp/canvas",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

Or run it on your computer

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "canvas": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@avatargaia/canvas-mcp"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

  • Authorization secret HTTP header
    Bearer 。可不带:匿名沙箱开放 list_templates / list_actions / open_canvas / canvas_action(免费动作)。自助拿 Key:POST https://agent.avatargaia.top/api/dev/register

Common questions

Is Canvas MCP safe?

It passed 2 of 2 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: Authorization

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.4) reached the registry 37 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Spec Driven Development, Remote Desktop Commander, Toggl 2.0

给数字员工喂知识(v0.4.0 起)

岗位可以配知识库:访客问到时,数字员工先查库再答,并把依据的那一页显示在画布上;库里没有的,它会直说没有。

工具作用
list_kbs我名下的知识库 + 每个岗位配了哪些库
read_kb库的页面清单,或某一页原文
publish_kb发布一套 wiki(整库替换,可顺手配给岗位);checked 不为 true 不发
set_staff_kbs设定岗位用哪些库
hire_staff按模板开岗,可带 kbs

三步:整理(一套 Markdown,wiki/index.md 总目录 + wiki/<主题>/<文章>.md,一个概念一篇,数字日期照原文写)→ 发布(publish_kb,库名 + 全部页面 + checked: true,同名再发是整库替换)→ 配给岗位(set_staff_kbs,或发布时带 slug,或 hire_staff 直接带 kbs)。

⚠️ 发布等于公开:岗位是匿名访客都能聊的,库里写了什么访客就能问出什么。个人隐私、客户资料、令牌、内部运维内容不要放。上限:200 个文件 / 单个 64KB / 合计 2MB。

行为

  • stdin/stdout 逐行 JSON-RPC 2.0;通知(无 id)不回包
  • 上游 HTTP 错误原样透传成 JSON-RPC error(401: Missing Authorization header / 402: … / 429: …),客户端能看见真正原因
  • 上游返回 SSE 或 JSON 都能解析(取最后一条 data:)
  • stdin 关闭后等所有在途请求落地再退出

验证记录(2026-10-03)

initialize   ✅ serverInfo teamagent-canvas 0.4.0

tools/list ✅ 91 个工具 publish_kb ✅ checked:false 被拦下;checked:true 发布成功 hire_staff ✅ 开岗并同时配知识库,返回里带 kbs set_staff_kbs ✅ 正向成功;跨账号岗位返回 404(越权被拒) 匿名调用 ✅ {"error":{"code":-32000,"message":"401: Missing Authorization header"}}

(早期 0.3.0 的 stdio 马甲验证:initialize / tools/list / tools/call / 无令牌 401 / mcporter 接入,均通过。)

拿 Key(自助,30 秒)

外部 / 本地 Agent 无需 TeamAgent 账号:

curl -X POST https://agent.avatargaia.top/api/dev/register \

-H "Content-Type: application/json" \ -d '{"name":"my-agent","email":"you@example.com"}'

→ 返回 dk_ Key(只显示一次)+ 20 credits + 接入信息

  • 开发者入口(控制台 / 计费 / 错误码):https://agent.avatargaia.top/developers
  • 机器可读自描述(Agent 自发现首选):GET https://agent.avatargaia.top/api/dev

工具注解

每个工具都带 MCP annotations(readOnlyHint / destructiveHint / idempotentHint / openWorldHint),付费工具在描述里写明 credit 数,客户端可据此做二次确认。
