sysketch tools (2)

write = sends, deletes, buys or posts
  • list_iconsFree

    List sysketch icon names and aliases, or search the available product logos.

  • render_diagramFree

    Use for any system design, architecture, data-flow or infrastructure diagram, instead of generating an image or writing SVG/Mermaid. Renders a tiny YAML spec; returns PNG/SVG links and a small preview. Spec keys: title, type (sequence: message timeline), theme (sketch|graphite|blueprint|midnight|classic), direction (omit: auto-fit; right|down only if asked), steps (false hides numbers), legend (true lists steps), nodes {id: "icon | Label | subtitle"}, groups {Label: [ids or group labels to nest]}, edges ["a > b > c | label", "a ..> b" dashed, "a <> b" two-way, "a => b" thick, "a -- b" line, "a > b [red]" color]. Ids that are icon names/aliases (client, lb, api, db, cache, redis, kafka, s3, cdn...) need no nodes entry. Arrows are numbered automatically in the order listed; don't number labels. Product names (stripe, kafka, postgres...) draw the product's logo when available, else a fitting icon; brand/icon (acme/queue) for others. Give the user the PNG link; don't generate another image of the diagram. To edit, call again with the whole updated spec.

What the publisher says

From the sysketch repository's README, as published. We do not edit it. Read it on GitHub

Describe your system in a few lines. Get a clean, hand-sketched architecture diagram. Works in ChatGPT, Claude, Perplexity and other AI chats, in coding assistants like Claude Code and Cursor, or on its own from the command line.

Why sysketch

When you ask an AI assistant for a diagram, it usually writes every line, box and coordinate by hand. That is slow, uses up a lot of your AI usage, and every diagram looks different.

With sysketch, the AI writes a short description of your system and sysketch draws it.

  • Faster and cheaper: 18x fewer AI output tokens and about 9x faster than having the AI draw the image itself (benchmark).
  • Consistent: every diagram shares the same polished style, icons and layout rules.
  • Easy to change: "add a cache in front of the database" is a one-line edit, not a redraw.
  • Works anywhere: SVG or PNG files that look the same in GitHub, Notion, Figma, docs and slides.

Get started

sysketch connects to AI assistants through MCP, the standard way to give them new tools. Pick the option that matches how you use AI.

In your AI chat (nothing to install)

Any web-based AI chat that supports custom connectors (also called MCP servers) can use sysketch, including Claude, ChatGPT and Perplexity. Add a custom connector with this URL. No account or sign-in is needed.

https://sysketch.vercel.app/mcp
  • Claude (web, desktop and mobile): Settings → Connectors → Add custom connector.
  • ChatGPT: turn on Developer mode (Settings → Apps & Connectors → Advanced), then create a connector with the URL and no authentication. Developer mode is available on paid plans.
  • Perplexity and other chats: look for custom connectors or MCP in the settings.

Then ask for a diagram:

Use sysketch to draw a ride-sharing app: rider and driver apps, an API gateway, a matching service, a location service and a trip database.

In Claude and ChatGPT the diagram opens right in the chat, with zoom, fullscreen and PNG/SVG download buttons. Other chats show a preview with links to the full PNG and SVG. To change it, just ask ("add a payment service"). Product names like stripe, kafka or postgres show the product's official logo (from Simple Icons). Nothing is stored on the server: each link contains the diagram's description, so anyone with the link can see that diagram. The AWS, Azure and Google Cloud icon packs and your own company's logos need the local version below. Setup and the connector's limits are in the hosted server guide.

In Claude Code, Cursor and other coding assistants

This runs sysketch on your computer and saves diagrams straight into your project. You need Node.js 20 or newer.

Claude Code: run this once in your terminal:

The last commit was 16 days ago (2026-10-17). The latest release is v0.5.0.
Is sysketch up?
100% of our last 26 checks got an answer. We check remote servers about four times a day.
What can I use instead of sysketch?
Servers from other publishers that do the same job: melta UI MCP server, Buoy MCP server and Network Sketcher (Local MCP) MCP server. Compare all sysketch alternatives.
How does sysketch compare with other Media MCP servers?
safety score 93/100 (higher than 91% of 1,337 Media servers); tools 2 (the typical Media server has 7); tools that change things 0% (typical: 5%. Fewer write tools means less an agent can break). Full comparison.
