Tools

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.

Builds editable Figma designs on the canvas from screens, modals or sidebars in your code, or from a text description, reusing components and variables from the file's published design system first. Maintained by Figma; needs the remote Figma MCP server and the figma-use skill.

Figma's official skill that teaches agents to run Plugin API scripts via use_figma, creating and editing nodes, components, variables and auto layout directly on the canvas. Load it before any use_figma call. Needs a Figma account and the remote MCP server.

Turns Figma designs into production code in your project, using the design screenshot as the visual target and reusing existing components, design tokens and Code Connect mappings first. Maintained by Figma; needs the Figma MCP server (free plans get only 6 calls a month).

Figma's official skill for building FigJam boards through the Figma MCP: sticky notes, sections, connectors, shapes and tables for brainstorms, retros and meetings. Needs a Figma account, the remote MCP server and the figma-use skill; canvas writes are free in beta; usage pricing is planned.

Figma's official plugin: connects the remote Figma MCP server and bundles skills for design-to-code, Code Connect, and generating designs and libraries, letting agents read design context and write to the canvas. Needs a Figma account; Starter plans and View/Collab seats get 6 calls a month.

Figma's official skill collection: implement designs as code, map components with Code Connect, generate design-system libraries from code, and build screens and FigJam diagrams on the canvas. Needs the Figma MCP server; canvas writes are in beta and currently free.

Figma's official skill: the agent writes Mermaid, then uses the Figma MCP to build flowcharts and sequence, state, Gantt and ER diagrams in FigJam for you to tweak by hand. Unsupported types like pie charts and mind maps are flagged upfront. Needs a Figma account and the remote MCP server.

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.

Breaks reference UIs you like (screenshots, images or URLs) into a structured design DNA JSON covering design tokens, overall style and visual effects, then builds new pages from your content in that style. Installing needs Node.js; no API key required.

Command-line tool for inspecting, compressing and optimizing glTF/GLB 3D models, with Draco and Meshopt mesh compression, texture resizing and WebP/KTX2 compression; a single optimize command handles it all.

SDK and CLI for reading, editing and optimizing glTF 2.0 3D models: one optimize command does it all, or run Draco and Meshopt geometry compression, texture resizing and WebP or KTX2 compression separately. Suits game and web 3D assets.

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.

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.

Higgsfield's official skills: generate images, video and voiceover from a single prompt for product shots, e-commerce hero images, YouTube thumbnails, brand guidelines and narrated explainers. Requires the Higgsfield CLI and a signed-in account; generations use account credits.

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.

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.

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.

Generates product shots, marketing posters and illustrations, removes or swaps backgrounds, upscales and makes videos, with 1,400+ prompt templates and parallel variations. Cloud use needs a MeiGen account and paid credits; the npm version can use OpenAI-compatible APIs or local ComfyUI.

Lets agents read and write your local Obsidian vault directly: search notes, append to daily notes, tidy tags and properties, and summarize reading or research notes by topic. No need to open Obsidian or install plugins; access is limited to the vault and can be read-only. Needs Node.js 20+.

From product photos and a brief, plans a full e-commerce visual set (main images, Amazon/Shopify detail pages, social promos, livestream scenes) with briefs and image prompts, using 25 scene templates and a consistent style. Renders with an OpenAI-compatible image API key; needs Python 3.10+.
