@avatargaia/canvas-mcp

stdio 马甲：让只支持 stdio 的 MCP 客户端（Claude Desktop / Cursor / 各类本地 Agent）接入 TeamAgent 的 Canvas MCP（streamable-http）。 纯转调，无状态、不缓存、不改写请求。

用

CANVAS_MCP_URL=https://agent.avatargaia.top/api/mcp/canvas \
CANVAS_MCP_TOKEN=ta_xxxxxxxx \
npx -y @avatargaia/canvas-mcp

客户端配置（Claude Desktop claude_desktop_config.json 为例）：

{
  "mcpServers": {
    "teamagent-canvas": {
      "command": "npx",
      "args": ["-y", "@avatargaia/canvas-mcp"],
      "env": {
        "CANVAS_MCP_URL": "https://agent.avatargaia.top/api/mcp/canvas",
        "CANVAS_MCP_TOKEN": "ta_xxxxxxxx"
      }
    }
  }
}

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
