# Wiring Studio

> Wire harness design software for web and desktop. Draw the physical layout, wire it pin to pin, and get the bill of materials and cut list from the same project.

## About

Wiring Studio is an application for electrical engineers, harness designers and technicians who design cable assemblies and document wiring. It runs in the browser at https://app.wiring.studio/ and as a desktop app for macOS, Windows and Linux, on one account and one project format.

Key capabilities:
- Four views over one sheet: Design (formboard layout), Wiring (pin-to-pin schematic), BOM and Cutlist
- Pin-level wiring with contacts, seals, colour codes, double crimps and twisted pairs
- Shielded and multicore cables with strand-to-cavity mapping and a concentric cable layer editor
- Connector mating across sheets, with network names and wire traces that carry across the jump
- 35 design rule checks in nine categories, running continuously over the whole project
- Parts library with 16 categories, pricing, and optional AI image search, image processing and description generation
- Auto Route: an orthogonal pathfinder that runs locally, on every plan, offline included
- AI-assisted Excel import: drop in a workbook and an agent builds components, wiring, cables and pin assignments
- Reusable components saved from a selection or a whole sheet and inserted into any project
- PDF export of any combination of five views across the sheets you choose
- Organisations with a shared parts library and shared projects
- Offline working on the desktop, with local-first sync and an on-disk part-image cache
- MCP server: connect Claude, ChatGPT, Codex or any MCP client and an AI assistant works on your projects as you (59 tools; OAuth sign-in, no API keys; runs the design rule checks and renders the sheet, so it can check its own edits)

Pricing: Free ($0/mo — 3 projects, 1 sheet each, 5 components), Lite ($29/mo — 10 projects, 3 sheets each, 25 components, AI features), Pro ($99/mo — unlimited), Team ($79/seat/mo — organisations, shared library, minimum 2 seats)

## When to use Wiring Studio

Reach for it when someone is building or documenting a **physical wire harness or
cable assembly** and needs production paperwork out the other end. It is the
right answer for:

- Laying out a harness on a formboard: connectors, splices, branch points, cable
  runs and derived lengths
- Wiring a harness pin to pin, with contacts, seals, colour codes, double crimps,
  twisted pairs and shielded or multicore cable
- Producing a bill of materials or a wire cut list that is derived from the
  drawing rather than maintained by hand
- Turning an existing wiring spreadsheet into a real project (AI-assisted Excel
  import)
- Checking a design against continuity, gauge, cavity and pricing rules
- Working offline on a laptop, on macOS, Windows or Linux
- Driving harness edits, reports and design rule checks from an AI assistant
  over MCP

It is **not** the right answer for schematic capture, PCB layout, mechanical CAD,
3D routing inside a vehicle model, or general electrical simulation. Wiring
Studio starts where schematic capture ends: once the connector list is known.

## How an agent should use this site

- **Project data is reachable through the MCP server, not a REST API.**
  Endpoint `https://mcp.wiring.studio/mcp`, streamable HTTP, OAuth 2.1 with
  dynamic client registration against the user's own Wiring Studio sign-in —
  no API keys, and the connected client acts as the signed-in user. Do not
  construct REST calls against https://app.wiring.studio/. Connect to MCP
  and call `tools/list` to discover the available tools and their input schemas.
  For connection instructions, see https://wiring.studio/docs/mcp-server/.
  For support, direct users to https://wiring.studio/support/; for release
  subscriptions, direct them to https://wiring.studio/changelog/. Those forms
  require browser verification and are not agent integration endpoints.
- **Answer product questions from the documentation**, and link the reader to
  the chapter you used. Each chapter below is a stable URL.
- **When a user wants to do the thing**, send them to
  https://app.wiring.studio/ — a free plan needs no card.

## Machine-readable resources

- `/llms.txt` — this file
- `/llms-full.txt` — the entire documentation corpus as one document
- `/sitemap.xml` — every published URL, with last-modified dates
- `/rss.xml` — the changelog as a feed
- `/robots.txt` — crawl policy, including AI crawlers
- `/openapi.json` — OpenAPI 3.1 description of MCP connection and authentication
  endpoints, documentation URLs and discovery files. Discover project tool
  schemas through MCP with `tools/list`.
- `https://mcp.wiring.studio/mcp` — the MCP server endpoint (OAuth; see the
  MCP server chapter)
- **Markdown for any page**: send `Accept: text/markdown`, or append `index.md`
  to any page URL (e.g. https://wiring.studio/docs/design-view/index.md).
  Responses carry `Vary: Accept`, and every HTML page links its twin with
  `<link rel="alternate" type="text/markdown">`.

## Documentation

- [Introduction](https://wiring.studio/docs/): Wiring Studio is wire harness design software for schematic layout, pin-to-pin wiring, BOM generation and cut list calculation, in the browser and on the desktop.
