Exa MCP Server(Operit 适配版)
本仓库是 exa-labs/exa-mcp-server v3.4.0 的 Operit 平台适配版。
原版 Exa MCP Server 用于将 Exa 的搜索能力(web search / code search / company research)接入 AI 助手;本适配版在保持全部功能不变的前提下,修复了 Exa MCP 与 Operit 平台(旧版 Kotlin MCP SDK / Zod schema 校验)握手失败的问题,使 web_search_exa / web_fetch_exa 等工具可在 Operit 中稳定加载与调用。
为什么需要适配(背景)
Operit 使用的 MCP 客户端 SDK 版本较旧,其 Zod 校验要求 serverInfo 响应中不允许出现 icons 字段:
现象 | 原因 |
MCP 插件一直"卡在加载" | 客户端发起 |
工具列表拉不到 / 工具不可用 | 握手未完成, |
本仓库将 src/stdio.ts 中 McpServer 构造参数的 icons 字段移除,并使源码与构建产物(dist/stdio.cjs)保持一致,构建可复现。
注:
dist/stdio.cjs中仍保留 SDK 库内部的IconSchema/IconsSchema定义(用于校验客户端传入字段的 schema 声明),这与 serverInfo 响应中的icons无关,不影响兼容性。

与原仓库的差异(全部)
文件 | 修改 | 说明 |
| 移除 | 兼容 Operit 旧 SDK 的 Zod 校验(修复根因) |
| 版本号 | 发布版本可识别,serverInfo 回显该版本 |
除此之外,工具集、API、skills、测试、Dockerfile、vercel 配置等均与上游 v3.4.0 完全一致。
快速开始
1. 构建(可复现)
npm ci # 安装依赖(国内可换 npmmirror 加速:npm config set registry https://registry.npmmirror.com)
npm run build:stdio # esbuild 打包 → dist/stdio.cjs(自包含,约 2.2MB)⚠️ npm 11+ 默认阻止 postinstall 脚本,若报
esbuild: command not found,执行:npm approve-scripts esbuild # 或 npm approve-builds node node_modules/esbuild/install.js
2. 验证握手(initialize)
node dist/stdio.cjs <<'EOF'
{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2025-06-18","capabilities":{},"clientInfo":{"name":"test","version":"1.0"}}}
EOF预期 serverInfo 响应(无 icons 字段):
{
"name": "exa-search-server",
"title": "Exa",
"version": "3.4.0-operit.1",
"websiteUrl": "https://exa.ai"
}3. 部署到 Operit
将本仓库(或仅
dist/目录)放入 Operit 的 MCP 插件目录:Android 源目录:
/sdcard/Download/Operit/mcp_plugins/<pluginId>/Linux 运行目录:
~/mcp_plugins/<shortName>/(含dist/stdio.cjs)
在
mcp_config.json注册(示例):
{
"mcpServers": {
"exa": {
"command": "node",
"args": ["dist/stdio.cjs"],
"env": {
"EXA_API_KEY": "<your-exa-api-key>",
"EXA_TOOL_ENABLES": "web_search_exa,web_fetch_exa"
}
}
}
}重启 MCP 服务(Operit 内触发
restart_mcp_with_logs),验证ping_mcp可列出工具。
可用工具
web_search_exa— 默认启用,Exa 语义搜索web_fetch_exa— 默认启用,任意 URL 转 Markdownweb_search_advanced_exa等高级工具 — 需在EXA_TOOL_ENABLES中追加工具名后启用
