A CLI and Python library by Simon Willison: imports JSON and CSV straight into SQLite with automatic table creation, runs in-memory SQL queries over files, and supports full-text search and table transformations.

Translation management for Ruby/Rails: statically analyzes code to find missing and unused keys, normalizes locale files, fills gaps via Google Translate, DeepL or OpenAI, and exports CSV for translators. Requires the i18n gem (Rails default) and Bundler; machine translation needs an API key.

Self-hostable long-term memory for agents, offering MCP, a REST API and a web dashboard: semantic search, knowledge graph and automatic memory consolidation. Embeddings are computed locally; choose SQLite, Cloudflare or Milvus as the backend.

Community-maintained GitLab MCP server: manage projects, merge requests, issues, pipelines, wikis and releases, with support for self-hosted instances and a read-only mode. Needs a GitLab personal access token or OAuth.

Microsoft's official Azure DevOps MCP server: query and act on work items, repos, pull requests, build pipelines, test plans and wikis. Sign in with a Microsoft account that has access on first use; Microsoft recommends the no-install remote version instead.

Stripe's official skill collection: payment integration best practices, SDK and API version upgrades, Connect platform onboarding and docs lookup, with content synced automatically from the Stripe docs.

Stripe's official plugin: bundles the remote Stripe MCP with skills for integration best practices, Connect, Stripe Apps and API upgrades, plus commands that explain errors and list test card numbers. Available in the official Claude and Codex marketplaces.

550+ medical research skills from AIPOCH: PubMed search strategy, study design and sample size, statistics and bioinformatics, journal writing and reviewer responses, all vetted by MedSkillAudit. Some need Python/R or database credentials; have researchers and clinicians review results.

Local text-to-speech CLI built on the open Kokoro model: batch-converts TXT, EPUB and PDF to MP3 or WAV by chapter, with multiple languages, voice blending and speed control; handy for audio versions of course materials. Needs Python 3.11-3.12 and two model files downloaded first.

Before tool calls run, blocks destructive Git and file commands (git reset --hard, rm -rf) and access to sensitive files like SSH keys and .env. Parses command semantics, so bash -c wrappers are caught too. Works with Claude Code, Codex and other coding CLIs; needs Node.js 18+.

The official W3C conformance checker for EPUB, maintained by the DAISY Consortium: finds issues that break the EPUB 2/3 specs and outputs a report, so self-publishing authors and editors can check books before release. Needs Java; download a release and run it with java -jar.

Searches and reads official Microsoft Learn documentation and code samples for Azure, .NET and more, so agents give fewer outdated answers about Microsoft tech. Maintained by Microsoft; the remote server is free and needs no key.

Adapts an explanation to its audience, from a 5-year-old to a high schooler, college student, parent or executive, adjusting vocabulary, analogies, tone and depth. Useful for teachers, parents and explaining expert topics to laypeople. No account or extra software needed.

Netlify's official CLI: deploy sites, run projects locally with Netlify Dev, manage environment variables, Functions and Blobs, and call the Netlify API directly. Needs Node.js 22.13+ and a Netlify account.

WordPress's official plugin that turns abilities registered through the Abilities API into MCP tools, resources and prompts, reachable locally over WP-CLI (STDIO) or over HTTP. Needs WordPress 6.9+; abilities are private by default and must be exposed manually.

Skills for solo founders: website SEO and AI search optimization (GEO), mining user needs from Reddit, X and GitHub, domain price comparison, Product Hunt search, and logo and banner generation. Some need API keys or tokens for Gemini, twitterapi.io, RequestHunt or Product Hunt.

Multi-engine web search MCP with no API key, supporting Bing, DuckDuckGo, Brave, Baidu, Sogou, CSDN, Juejin and more; also fetches page content, CSDN articles and GitHub READMEs. Ships a CLI and a local server too.

Full-lifecycle tool for serverless apps (the s command): describe an app in YAML and deploy it to FaaS platforms such as Alibaba Cloud Function Compute, AWS Lambda and Tencent Cloud SCF, with CI/CD integration. A CNCF Sandbox project; needs cloud provider credentials.

German-language HR plugin for German startups of about 100 people: employment contracts, DATEV payroll handoff, personnel files and data protection, AGG complaints, works councils, absences, benefits and dismissals under German labor law. German law only; have a lawyer or HR pro review.

MathWorks' official server that lets agents start your local MATLAB, write and run scripts and unit tests, and check code style and potential errors, for computing, simulation and data analysis. Needs a licensed MATLAB R2021a+ and the downloaded server binary.

Recommends daily papers from arXiv and Semantic Scholar by research interest, reads them and writes illustrated Obsidian notes and a paper graph; can also search venues like CVPR and NeurIPS. Needs Python 3, Obsidian, a vault path and an interests config; the web app needs an Anthropic API key.

Command-line reference and bibliography manager: add papers by DOI with metadata fetched automatically, search by author, title or tag, and import or export BibTeX. Each entry is a readable YAML file that agents can read and write easily; a web UI is included. Needs Python.

Manages stacked branches and dependent pull requests with the gh stack GitHub CLI extension: splits work into layered branches with one PR each, then handles push, submit, sync, rebase and merge, using flags that keep commands non-interactive for agents. Official GitHub skill.
