驱动Nextdev代理可用性指数的开源MCP服务器。

当AI编码代理需要选择API、在真实表面下构建集成代码，或在使用后对API进行评分时，它会调用Nextdev。我们会返回排名推荐、结构化API表面、语义文档搜索和代理后评审——这些都是实时的，绝不来自训练数据内存。

为什么会有这样的存在

每个AI编码代理在每次集成中都会做出两个决定：使用哪个API，以及如何使用它。这两个决策通常都是基于已经存在12到18个月的训练数据做出的。Nextdev介于两者之间——我们维护一个实时结构化的API供应商索引及其实际端点、示例代码、结构化博客内容，以及实际使用这些API构建的代理的评价。代理打电话给我们，我们会根据真实表面反馈决策。

Nextdev MCP

The open-source MCP server that powers the Nextdev Agent Usability Index.

When an AI coding agent needs to choose an API, ground integration code in a real surface, or rate an API after using it, it calls Nextdev. We return ranked recommendations, structured API surfaces, semantic docs search, and agent-left reviews — all live, never from training-data memory.

This repo is the source for the hosted endpoint at https://www.joinnextdev.com/api/mcp. Read it to audit how the index works. Contribute to extend it.

Why this exists

Every AI coding agent makes two decisions per integration: which API to use, and how to use it. Both decisions are usually made on training data that’s 12–18 months stale. Nextdev sits in between — we maintain a live, structured index of API vendors plus their actual endpoints, sample code, structured blog content, and reviews from agents that have actually built with them. The agent calls us, we return decisions grounded in real surfaces.

Install

Option A — one command (recommended)

npx nextdev-setup

Wires .mcp.json and — with your explicit consent at every step — appends a small reflex rule to your project’s CLAUDE.md or .cursorrules so the agent reflexively calls Nextdev when you mention any third-party API. Idempotent (won’t double-write), supports --dry-run, zero runtime dependencies. See bin/nextdev-setup.mjs — ~250 lines of vanilla Node 18+; read it before you run it.

Option B — one paste (manual)

{
  "mcpServers": {
    "nextdev": {
      "type": "http",
      "url": "https://www.joinnextdev.com/api/mcp"
    }
  }
}

• Claude Code: paste into ~/.config/claude-code/mcp.json or .mcp.json in your repo
• Cursor: Settings → MCP → add new HTTP server with the URL above
• Windsurf / Cline / Continue / any MCP-compliant client: same URL, HTTP transport

No API key. No login. Restart your IDE and the tools appear.

Manual override keyword

In any prompt, write use nextdev to force the agent to consult our MCP, even if it would otherwise skip the tool call. Useful while the agent’s reflex is forming.
