中文说明

Uapi Mcp 是 uapis.cn 的官方 MCP Server，把 UAPI 的搜索、翻译、图像、文本处理、网页解析能力整合成一个标准化接口，支持任何 MCP 协议客户端。

快速开始

方式一：直接安装资源包

如果您希望尽快装好并开始使用，最省事的方式是直接下载已经打包好的 mcp-server.mcpb：

• 最新下载地址：https://github.com/AxT-Team/uapi-mcp/releases/latest/download/mcp-server.mcpb
• 安装完成后，在资源包配置里填写 uapikey
• 如果后面需要管理员范围工具，再补 UapiAdminBearerAuth

这种方式不需要您自己手动构建，也不需要额外整理命令行参数。

方式二：从源码运行

如果您准备自己修改、调试或者二次打包，可以直接从源码运行。

环境要求

• Node.js 18 或更高版本
• npm
• 首次构建会自动安装并使用 Bun

安装依赖

npm install

构建

npm run build

启动本地 stdio 服务

如果客户端可以直接拉起本地 MCP 进程，建议这样启动：

node ./bin/mcp-server.js start --mode dynamic

启动 Streamable HTTP 服务

如果客户端可以直接连接远程 MCP URL，建议这样启动：

node ./bin/mcp-server.js serve --mode dynamic --port 39002

启动后入口地址是：

http://127.0.0.1:39002/mcp

启动 SSE 服务

如果客户端仍然依赖 SSE，可以这样启动：

node ./bin/mcp-server.js start --transport sse --mode dynamic --port 39001

启动后可以访问：

• 首页：http://127.0.0.1:39001/
• SSE：http://127.0.0.1:39001/sse

客户端配置

通用本地配置

下面这份配置适合大多数可以本地拉起 MCP 进程的客户端。请把路径改成您自己的实际目录。

{
  "mcpServers": {
    "Uapi Mcp": {
      "command": "node",
      "args": [
        "C:/path/to/uapi-mcp/bin/mcp-server.js",
        "start",
        "--mode",
        "dynamic"
      ],
      "env": {
        "UAPI_MCP_UAPIKEY": "YOUR_UAPI_KEY"
      }
    }
  }
}

Codex 通过 HTTP 连接

如果您已经把服务跑在本机 39002 端口，可以这样配置：

[mcp_servers."Uapi Mcp"]
url = "http://127.0.0.1:39002/mcp"
http_headers = { "UapiKey" = "YOUR_UAPI_KEY" }

如果还需要管理员范围工具，再加上管理员 Token：

[mcp_servers."Uapi Mcp"]
url = "http://127.0.0.1:39002/mcp"
http_headers = { "UapiKey" = "YOUR_UAPI_KEY", "UapiAdminBearerAuth" = "YOUR_ADMIN_TOKEN" }

MCP Bundle

如果您想安装资源包，可以先执行：

npm run mcpb:build

执行完成后会生成：

./mcp-server.mcpb

这个包已经内置了 user_config.uapikey。安装时把自己的 Key 填进去即可。

配置项

uapikey

uapikey 会用于所有上游请求，适合公开工具和日常使用场景。您可以通过下面几种方式配置：

• 命令行参数：--uapikey YOUR_UAPI_KEY
• 环境变量：UAPI_MCP_UAPIKEY=YOUR_UAPI_KEY
• HTTP 请求头：UapiKey: YOUR_UAPI_KEY
• MCP Bundle：user_config.uapikey

服务端会把它统一转换成上游的：

Authorization: Bearer YOUR_UAPI_KEY

UapiAdminBearerAuth

UapiAdminBearerAuth 只在管理员范围工具里需要。您可以通过下面几种方式配置：

• 命令行参数：--uapi-admin-bearer-auth YOUR_ADMIN_TOKEN
• 环境变量：UAPI_MCP_UAPI_ADMIN_BEARER_AUTH=YOUR_ADMIN_TOKEN
• HTTP 请求头：UapiAdminBearerAuth: YOUR_ADMIN_TOKEN

服务端同样会把它转换成上游的：

Authorization: Bearer YOUR_ADMIN_TOKEN

如果 uapikey 和 UapiAdminBearerAuth 同时存在，管理员 Token 会优先生效。

运行模式

默认建议使用 dynamic 模式。这个模式不会在连接建立时一次性暴露全部业务工具，而是先提供 4 个元工具：

• list_tools
• describe_tool_input
• execute_tool
• list_scopes

对于工具数量比较多的服务，这种方式更省上下文，也更容易让模型按需调用。

常见问题

公开工具需要配什么

大多数情况下，只配 uapikey 就够用了。

访客额度用完怎么办

如果访客额度或免费积分用完了，可以先注册 UapiPro：https://uapis.cn。注册完成后，到 UapiPro 控制台创建 UAPI Key，再把这个 Key 填到 MCP 客户端或者资源包里的 uapikey 配置里，就可以继续使用。

管理员工具需要配什么

管理员范围工具需要额外传 UapiAdminBearerAuth。如果没有这个配置，服务端会直接返回可读的错误提示。

常用命令

查看 CLI 帮助：

node ./bin/mcp-server.js --help

只启动公开只读工具：

node ./bin/mcp-server.js serve --mode dynamic --scope read

只启动管理员工具：

node ./bin/mcp-server.js serve --mode dynamic --scope admin --uapi-admin-bearer-auth YOUR_ADMIN_TOKEN

运行回归检查：

npm run test:regression

打包 MCP Bundle：

npm run mcpb:build

Installation

> [!TIP] > To finish publishing your MCP Server to npm and others you must run your first generation action.

Claude Desktop

Install the MCP server as a Desktop Extension using the pre-built [mcp-server.mcpb](./mcp-server.mcpb) file:

Simply drag and drop the [mcp-server.mcpb](./mcp-server.mcpb) file onto Claude Desktop to install the extension.

The MCP bundle package includes the MCP server and all necessary configuration. Once installed, the server will be available without additional setup.

> [!NOTE] > MCP bundles provide a streamlined way to package and distribute MCP servers. Learn more about Desktop Extensions.

Stdio installation via npm To start the MCP server, run:

npx uapi-mcp start --uapi-admin-bearer-auth 

For a full list of server arguments, run:

npx uapi-mcp --help

Progressive Discovery

MCP servers with many tools can bloat LLM context windows, leading to increased token usage and tool confusion. Dynamic mode solves this by exposing only a small set of meta-tools that let agents progressively discover and invoke tools on demand.

To enable dynamic mode, pass the --mode dynamic flag when starting your server:

{
  "mcpServers": {
    "UapiMcp": {
      "command": "npx",
      "args": ["uapi-mcp", "start", "--mode", "dynamic"],
      // ... other server arguments
    }
  }
}

In dynamic mode, the server registers only the following meta-tools instead of every individual tool:

• list_tools: Lists all available tools with their names and descriptions.
• describe_tool: Returns the input schema for one or more tools by name.
• execute_tool: Executes a tool by name with the provided input parameters.
• list_scopes: Lists the scopes available on the server.

This approach significantly reduces the number of tokens sent to the LLM on each request, which is especially useful for servers with a large number of tools.

You can combine dynamic mode with scope and tool filters:

{
  "mcpServers": {
    "UapiMcp": {
      "command": "npx",
      "args": ["uapi-mcp", "start", "--mode", "dynamic", "--scope", "admin"],
      // ... other server arguments
    }
  }
}
