AT Series MCP Hub

把 AT 系列 IDE 插件的 MCP 入口收成 一条:AT Series → ~/.at-series/mcp/hub.js。

各能力插件(SSH / JumpServer / 未来新产品)在扩展宿主内跑自己的 Bridge,向 Hub 注册工具;Hub 只负责聚合 tools/list、路由 tools/call、监听 registry。凭据、确认弹窗、业务逻辑仍留在插件内。

npm 包 @at-series/mcp-hub 0.1.0(packages/mcp-hub)
接口规范 docs/protocol/v1.md(对接真源)
契约类型 packages/mcp-hub/src/protocol(随包导出,与规范同步)
当前阶段 P0a 已完成:Hub 运行时 + publisher + installer;插件迁移见 P0b/P0c

文档

对接本服务前,请先读规范与接入指南:

文档 说明
docs/protocol/v1.md 接口契约真源:registry、Bridge HTTP、Hub 聚合/路由、MCP 配置、错误体、版本选举
docs/guides/plugin-integration.md 新插件接入步骤(Bridge → publish → syncHubBundle → installer)
docs/requirements.md 产品范围、决策与验收标准
docs/decisions/ADR-001-at-series-mcp-hub.md 为何采用共享 Hub 架构
AGENTS.md 本仓 Agent / 迁移工程约定

插件作者以实现 docs/protocol/v1.md 为准,不要靠读 Hub 源码猜接口。类型从 @at-series/mcp-hub 导入,须与规范同变更集保持一致。

架构

IDE MCP Client (Cursor / Kiro / Continue / …)
        │  stdio  MCP server name: "AT Series"
        ▼
~/.at-series/mcp/hub.js          ← @at-series/mcp-hub 打包的单文件入口
        │  读 registry + HTTP
        ▼
~/.at-series/bridges/<hostApp>/<bridgeId>.json
        │
        ▼
插件 Bridge  127.0.0.1:<port>
  GET /health · GET /tools · POST /invoke
        │
        ▼
插件域服务(SSH / JumpServer / …)+ 确认 / 凭据

边界(本仓不做): 不提供通用 Bridge HTTP 框架;不实现 SSH/JumpServer 业务;不把确认 UI 搬进 Hub;不按插件写死工具清单。

已实现能力(P0a)

模块 职责 主要 API
protocol 类型、常量、risk/autoApprove 纯函数、路径助手 AT_SERIES_PROTOCOL_VERSION、BridgeRegistryRecord、hubJsPath() …
registry 读/校验 bridges/<hostApp>/*.json;目录 watch listBridgeRecords、watchBridgeRegistry
publisher 写 registry;心跳;卸载自身记录;选举写入 hub.js FsBridgePublisher、syncHubBundle
hub runtime stdio MCP:聚合工具、路由 invoke、at_list_providers、list_changed createHubRuntime;产物 dist/hub.js(@at-series/mcp-hub/hub)
installer 写/修/卸 AT Series;迁移旧 AT 条目;按 risk=read 算 autoApprove ensureAtSeriesMcpConfig、uninstallAtSeriesMcpConfig、defaultAutoApproveToolNames

覆盖 IDE:Cursor(~/.cursor/mcp.json)、Kiro、Continue(workspace .continue/mcpServers/)。

测试:npm test(含协议一致性、双插件聚合、选路、hostApp 隔离、hub 版本选举、installer 迁移等)。

新插件怎么接入

契约真源: docs/protocol/v1.md。
操作指南: docs/guides/plugin-integration.md。
类型从包导入:import … from '@at-series/mcp-hub'。

最小闭环:

  1. 实现 Bridge:127.0.0.1 + x-at-series-token + GET /health / GET /tools / POST /invoke
  2. publish registry 到 ~/.at-series/bridges/<hostApp>/<bridgeId>.json(protocolVersion: 1,工具带 risk)
  3. MCP 变体:syncHubBundle 选举 hub.js,ensureAtSeriesMcpConfig 只写 AT Series
  4. deactivate 时 unpublish(只删自己的 registry;不删 hub.js、不卸 MCP 配置)

依赖

npm install @at-series/mcp-hub
# 本地联调可用 file: / workspace 依赖,直至 npm 发版

activate 示例

import {
  FsBridgePublisher,
  syncHubBundle,
  ensureAtSeriesMcpConfig,
  hubJsPath,
  AT_SERIES_PROTOCOL_VERSION,
  type BridgeRegistryRecord,
  type ToolCatalogEntry
} from '@at-series/mcp-hub';

const bridgeId = crypto.randomUUID(); // MUST be UUID
const hostApp = 'cursor';
const tools: ToolCatalogEntry[] = [
  {
    name: 'example_ping',
    title: 'Example Ping',
    description: 'Connectivity check.',
    risk: 'read',
    inputSchema: { type: 'object', properties: {} }
  }
];

await syncHubBundle({
  version: '0.1.0', // 所打包的 hub 包 semver
  bundlePath: require.resolve('@at-series/mcp-hub/hub'),
  pluginId: 'at.example',
  pluginVersion: '1.2.3'
});

await ensureAtSeriesMcpConfig({
  target: 'cursor', // 'kiro' | 'continue'(continue 须传 workspaceFolder)
  hostApp,
  hubJsAbsolutePath: hubJsPath(),
  registryTools: tools
});
// 可选:defaultAutoApproveToolNames({ registryTools: tools })

const publisher = new FsBridgePublisher({ bridgeId, hostApp });
const record: BridgeRegistryRecord = {
  protocolVersion: AT_SERIES_PROTOCOL_VERSION,
  bridgeId,
  pluginId: 'at.example',
  pluginDisplayName: 'AT Example',
  pluginVersion: '1.2.3',
  hostApp,
  port: 43123,
  token: '<high-entropy-secret>', // 禁止明文日志
  pid: process.pid,
  updatedAt: Date.now(),
  tools
};
await publisher.publish(record);
// 存活期间每 ≤30s: await publisher.heartbeat();
// deactivate: await publisher.unpublish();

Hub 版本选举: semver 更高 → 覆盖;同版本且 bundleSha256 不同 → 覆盖(热修);同版本同 hash → no-op;更低 → 禁止覆盖。

autoApprove: 仅 risk=read + 内置 at_list_providers;write/exec 必须在插件内确认。

不要: 再写 per-plugin mcp-server.js 作为产品入口;不要注册 languageModelTools 暴露同一批工具。
