国信智能体实名关联服务 MCP Server — 单个可执行文件 · 本地通信 · 国密加密 · 全平台支持。
为 AI Agent 提供 SM2 实名身份关联、SD-JWT 可验证证明(VP)生成与验证、SM2 密码学操作等能力。
必须全局安装(
-g)。这样realagent-mcp会进入 PATH,MCP 配置里的npx realagent-mcp才会命中全局副本,而不会每次都往_npx缓存里再拉一份 (即避免依赖重复与 npx 旧缓存问题)。
配置 MCP Client(--agent-id 必填,每个 Agent 使用唯一名称):
升级后重启 MCP Client 即可。Agent 会在每次对话开始时自动调用 system_update 检查新版本。
MCP Server 运行时动态暴露以下 14 个工具:
| 工具 | 说明 |
|---|---|
identity_link | 发起实名关联:生成二维码,用户扫码认证后自动领取实名凭证(VC) |
identity_status | 查询当前 Agent 的实名关联状态与身份信息 |
identity_revoke | 注销实名关联并作废凭证 |
| 工具 | 说明 |
|---|---|
identity_vp | 生成 SD-JWT 可验证证明(VP),支持选择性披露字段 |
identity_verify_vp | 验证 VP 的签名与披露内容 |
vp_parse | 解析 VP 结构,提取披露的声明字段 |
| 工具 | 说明 |
|---|---|
vc_info | 查询本地已领取的可验证凭证(VC)摘要信息 |
vc_raw | 获取 VC 原始数据 |
key_info | 查询本地 SM2 密钥对与指纹信息 |
| 工具 | 说明 |
|---|---|
crypto_sign | 使用 SM2 私钥对数据签名 |
crypto_verify | 验证 SM2 签名 |
crypto_encrypt | SM2 加密数据 |
crypto_decrypt | SM2 解密数据 |
| 工具 | 说明 |
|---|---|
system_update | 检查 MCP Server 是否有新版本 |
以下内容供 AI Agent 读取,用于自动完成安装和配置。
Prerequisite — verify Node.js (do this FIRST, before installing). realagent-mcp requires Node.js >= 18.13 (npm and npx are bundled with it). Before installing, check the environment:
node --version and npm --version. If both succeed and
node --version reports >= v18.13, skip to step 2.node/npm is not found (no Node.js) or the version is older than
18.13, stop and help the user set it up before going further:
winget install OpenJS.NodeJS.LTS (PowerShell), or
download the LTS installer from https://nodejs.org.brew install node@22, or nvm install --lts (nvm:
https://github.com/nvm-sh/nvm).nvm install --lts (nvm:
https://github.com/nvm-sh/nvm), or the NodeSource repo for your
distro.node --version, npm --version,
and npx --version. Only proceed to step 2 once all three succeed and
Node >= 18.13 is confirmed.Install via npm (global, so realagent-mcp is on PATH):
MCP client config — Each agent MUST have a unique --agent-id.
One agent-id = one identity = one SM2 key pair. Never reuse an agent-id
across agents. The realagent platform registers each key pair as a
separate identity; shared agent-id causes identity conflicts.
Generate an agent-id yourself, using a descriptive name based on the current project or the agent's purpose (e.g. "my-claude-code", "frontend-dev-helper", "pr-review-bot"). Use lowercase letters, digits and hyphens only. Then ASK the user to confirm before using it:
I'll configure realagent-mcp with agent-id: <name>. This name will be used to derive your unique SM2 identity. Is that OK? You can change it to any name you prefer.
Once confirmed, write this MCP config:
Data is stored under .realagent/agents/ in the working directory.
Add --data-dir to customize the path.
Restart the MCP client. The server exposes 14 tools (5 identity + 4 key/VC
identity_status.Version check — Call system_update at the start of each conversation
(or at least once per day). When an update is available, tell the user and
help them run npm update -g realagent-mcp or npm i -g realagent-mcp@latest. Only
skip the version check if the user explicitly asks you to.
