Lets agents query AWS bills, cost trends, budgets and spending anomalies, and recommends Savings Plans, Reserved Instances and rightsizing. Maintained by AWS; requires AWS credentials.

Official AWS MCP that searches and reads AWS documentation, converts it to Markdown for agents to cite, and suggests related pages. No AWS credentials needed; requires uv.

Anthropic's official employment law plugin: reviews hiring and termination risk by jurisdiction, classifies workers, tracks leave deadlines, manages internal investigations, and drafts policies with state supplements. Focused on US state law; output needs attorney review.

Anthropic's official legal plugin marketplace: 13 plugins covering commercial contracts, privacy, product counsel, M&A, employment, regulatory, AI governance, litigation and IP, plus plugins for law school clinics and law students. All output is a draft for attorney review.

Extracts the main content of a web page, stripping comments, sidebars, headers and footers, and outputs clean HTML or Markdown with metadata like title, author and publish date, saving tokens when agents read the web. Built for Obsidian Web Clipper by kepano; still in development.

Rendering engine that lays out HTML and CSS and exports PDF, supporting paged media and other print style standards, ideal for generating reports, invoices and receipts in bulk. Written in Python; depends on the system Pango library.

NVIDIA's open-source LLM vulnerability scanner that probes for prompt injection, jailbreaks, data leakage, hallucination and harmful content, supporting OpenAI, Hugging Face, Bedrock and most REST-accessible models. Scanning cloud models needs their API keys.

Annotate and review agent-generated plans, docs and code diffs in the browser, then send feedback back to the agent in one click. Hooks into plan mode and supports Claude Code, Codex and other agents. Run the official install script to set up the CLI first.

Official skill for Anarlog (formerly Hyprnote), an open-source, local-first meeting notes app: lets agents query notes, summaries, transcripts, attendees and action items from local data, with no meeting bot needed. Requires the Anarlog desktop app and CLI; remote cloud access needs Pro.

High-accuracy retrieval-augmented Q&A over paper PDFs, text and Office documents, filling in citation metadata, checking retractions and attaching traceable sources to answers. Provides the pqa CLI and a Python library. Needs an LLM API key by default; local models can be configured.

Tencent's open-source browser bridge: through the bsk CLI and a Chrome/Edge extension, agents use your logged-in accounts in a separate visible window to browse, fill forms and take full-page screenshots, and correlate network requests with console output to debug sites.

Git worktree manager (wt) built for running multiple AI agents in parallel: create, switch and clean up worktrees by branch name, and spin up a worktree and launch Claude in one command. Supports hooks, LLM-generated commit messages and one-step merges.

Uses a strong model to audit your codebase and list evidence-backed issues across correctness, security, performance and testing, writes a plan a cheaper model can execute, and reviews the results. It never edits code itself. By shadcn.

Say build a harness for this project and it designs a domain-specific agent team, generating subagent definitions, companion skills and orchestration, validates them and keeps evolving them from feedback. Supports workflow orchestration, persistent agent teams and subagent delegation.

Manages multiple Claude Code, Codex, Gemini and Aider sessions in parallel from one terminal: each task gets its own git worktree, can run in the background, and changes are reviewed before merging. Requires tmux and gh.

Google Workspace CLI for scripts and agents covering Gmail, Calendar, Drive, Docs, Sheets, Contacts and Tasks, with JSON output, read-only mode and command allowlists; can also run as a read-only-by-default MCP server. Bring your own Google OAuth client.

Free remote MCP service that turns any GitHub repo or GitHub Pages site into a docs endpoint, so agents can read up-to-date docs and search code on demand and hallucinate fewer APIs. No sign-up or install; self-hosting is also possible.

Spec-driven project management for software: guides brainstorming into a PRD, breaks it into epics and dependent tasks synced as GitHub Issues, answers standup, next-step and blocker questions, and can dispatch several agents to code in parallel. Needs Git, an authenticated gh CLI and a GitHub repo.

HTTP client CLI that reimplements HTTPie's syntax in Rust with a focus on performance; key-value pairs on the command line are sent as JSON by default, making it quick to debug REST APIs.

Offline speech toolkit for Apple Silicon Macs: CLI text-to-speech (including Chinese and voice cloning) and speech-to-text, for voicing lessons and explainer videos or transcribing lectures and interviews, with data staying local. Needs an M-series Mac and Python 3.10+; MP3 export needs ffmpeg.

Query, modify and convert JSON, YAML, TOML, XML, CSV, HCL, INI and more with one selector syntax, editing config files in place or converting between formats, handy for agents handling structured data in scripts. A single dependency-free binary that works much like jq or yq.

Moonshot AI's official terminal coding agent: reads and edits code, runs commands, searches files and fetches web pages, with video input, MCP, plugins, subagents and hooks, plus Zed and JetBrains integration via ACP. Needs a Kimi sign-in or Moonshot API key. Replaces the archived Kimi CLI.

From Trail of Bits: reviews PRs, commits or diffs from a security angle, tracing history with git blame, estimating blast radius by caller count and checking test coverage gaps, then writes a Markdown review report.

Diffusion model inference in pure C/C++: one sd-cli command runs SD, FLUX, Qwen Image, Wan and more locally to create or edit images and short videos, with Metal acceleration on Mac. No cloud needed; bring your own model weights and use a release binary or build from source.
