分类: 开发者工具
你需要填写：GITHUB_TOKEN, X-GitHub-Token

安装

选择你使用的 AI 应用，然后复制设置。

安装之前

你用的是哪个应用？

ClaudeClaude CodeCursorVS CodeChatGPT

在上方选择你的应用。我们会记住它，下次按钮会显示“安装到 …”。

这个地址需要在请求的 header 中放入密钥，而添加连接器的菜单无法设置。请改用 Claude Code、Cursor 或 VS Code。

或者在你的电脑上运行

打开 Claude Desktop → Settings → Developer → Edit Config，把下面的内容粘贴到 claude_desktop_config.json

需要你填写的值

GITHUB_TOKEN 机密 env
Optional. Raises GitHub's search limit from 10 to 30 requests per minute. A fine-grained token with no permissions is enough.
WHICHLIB_TELEMETRY env
Optional. Set to "off" to disable anonymous call counting (tool name, random install id, version, platform, Node major). DO_NOT_TRACK=1 also disables it.
X-GitHub-Token 机密 HTTP header
Optional. Your own GitHub token for unlimited use (otherwise 50 free calls per day). Used for your request only, never stored.

常见问题

whichlib 安全吗？

它在 3 项适用的基础检查中通过了 3 项。我们没有阅读代码。在添加密钥或令牌之前，请先看看这个服务器要求哪些权限，并使用只具备所需权限的密钥。

它需要哪些密钥或代码？

你需要填写：GITHUB_TOKEN, X-GitHub-Token

它在我的电脑上运行还是在云端？

两种方式都可以：安装在你的电脑上，或者连接云端版本。

它还在维护吗？

GitHub 仓库最后更新于–，最新版本（0.2.4）于11天前进入注册中心。

哪些应用可以使用它？

支持 MCP 的应用，例如 Claude Desktop、Claude Code、Cursor 和 VS Code。它通过 URL 连接，所以接受远程 MCP 服务器的应用也可以使用，例如开启开发者模式的 ChatGPT。

有什么可以替代它？

同一分类中有：GitHub, Desktop Commander, Cloudflare MCP

whichlib

The dependency picker for coding agents. Ask which library to use and get a scored, verified answer instead of a guess.

whichlib is an MCP server with three tools. It speaks MCP 2026-07-28; older clients keep working. Every repository it returns carries a transparent 0–100 score (momentum, maintenance, adoption including npm and PyPI downloads, license), a tier, a one-line verdict and the full breakdown, so the agent can justify the pick and you can read why.

For teams (waitlist): alerts when a dependency your repos use goes stale, and rules your team's coding agents must follow when they add one. Add a 👍 to the waitlist issue; at 20 signups it gets built. whichlib itself stays free.

Install

Claude Code:

claude mcp add whichlib -- npx -y whichlib

Cursor, Windsurf and other MCP clients:

{ "mcpServers": { "whichlib": { "command": "npx", "args": ["-y", "whichlib"] } } }

Requires Node 22 or newer. No account, no API key.

Use it without installing (hosted, no Node needed):

claude mcp add --transport http whichlib https://whichlib.com/mcp

Limits and the web API: https://whichlib.com/docs/

Tools

Tool	Ask	You get
`recommend_repos`	`need` in plain words, optional `language`, `limit` 1–10	The best repositories for the need, ranked by fit (score × relevance), with downloads and a verdict each
`compare_repos`	`repos`: 2–10 names as `owner/repo`	The repositories side by side, best first, same breakdown
`trending_repos`	`period` day / week / month / rising, optional `language`, `limit`	Most-starred repositories created in the period, scored; `rising`: repositories of any age by stars gained this week

Example, in Claude Code: "which Python PDF parser should I use?" → MinerU, pdfplumber, pypdf with scores, weekly downloads and verdicts like "Rising fast, 26k downloads/wk, pushed 3 days ago, Apache-2.0".

Score

Part	Weight	Signal
Momentum	40%	Stars gained over 7 days (from daily star counts when available), else stars per day since creation, scaled by the npm/PyPI download trend when known (0.5–2x). Log scale.
Maintenance	25%	Days since last push, full marks to 30 days, zero at a year. Widely used repos (10k+ stars or 100k+ weekly downloads) never drop below half.
Adoption	25%	Stars, forks and npm / PyPI weekly downloads, log scale.
License	10%	Permissive 1.0, weak copyleft 0.75, strong copyleft 0.5, none 0.

Tiers: Strong ≥ 75, Solid ≥ 50, Watch ≥ 25, Avoid; repos younger than 30 days are New ("Too new to judge"), whatever their score. Archived repos are capped at 20. On a 20-need eval the top recommendation is an accepted answer 75% of the time and the top five contain one 100% of the time; the eval and its reports live in the repository.

Environment variables, all optional

GITHUB_TOKEN: raises GitHub's search limit from 10 to 30 per minute. A fine-grained token with no permissions is enough. Recommend makes three searches per call.
WHICHLIB_HISTORY=off: do not download daily star counts. By default the server keeps the last 10 days in ~/.whichlib/stars/, refreshed in the background at most every 12 hours from raw.githubusercontent.com, so momentum uses real stars gained per week for the top 1,000 repos per language and new trending repos. Nothing is sent with that download.
FRESH_REPOS_DATA_DIR: a folder of daily snapshots or star counts to use instead (see the repository's data branch).
WHICHLIB_TELEMETRY=off or DO_NOT_TRACK=1: disables anonymous call counting. What is counted: tool name, a random install id, version, platform, Node major version, the MCP protocol version of the call. Never queries, repository names or results. The aggregate numbers are public at https://whichlib-telemetry.todorovskijosif.workers.dev/stats.

Source, dashboard, data

Repository: https://github.com/josifb/whichlib (MIT). It also holds the Fresh Repos dashboard (most-starred new repositories, day / week / month, sortable, one HTML file), the nightly snapshot and enrichment jobs, the recommendation eval, and 80+ unit tests.

Development, from the whichlib/ folder of the repository:

npm test           # unit tests, no network

npm run mcp:smoke # start the server over stdio and call every tool live npm run eval # 20-need recommendation eval (set GITHUB_TOKEN) npm run snapshot # today's top repos per period and language -> data/snapshots/ npm run enrich # add npm / PyPI packages and weekly downloads to the latest snapshot npm run score # top repos from the latest snapshot with score and verdict npm run pull-data # copy snapshots from the data branch
