Open Source AI PCB Design

Your AI agent designs the circuit board.

faezor-pcb is a PCB workbench for AI agents: KiCad, a router and a placer that finish the job, and the checks KiCad does not do. Run it on your own machine, or connect your agent to our hosted workbench - both free.

Connect your agent, free Run it yourself

Works with Claude, Codex, Cursor, Copilot and any agent that speaks MCP.

A four-layer motion controller, placed, routed and checked by an AI agent.

Hosted MCP, free

Your agent, our workbench.

Your agent and your model account do the thinking; our servers do the compute. Every board gets its own workbench with KiCad, the router, the placer and the checks.

1
Connect your agent
Add faezor as an MCP server and sign in once. A free account, no API key, nothing to install.
2
Describe the board
What it does, how it is powered, its connectors, size and layers. Your agent asks what it needs to know.
3
Watch it work
Your agent places, routes and checks the board on our workbench, following faezor's design rules. Every step shows on the board's page, live.
4
Order it
The KiCad project and the files your manufacturer needs: Gerbers, bill of materials, pick-and-place.

Claude Anthropic · Claude Code, claude.ai and the Claude apps

Claude Code

claude mcp add --transport http faezor https://faezor.ai/mcp

claude.ai, Desktop, mobile: connector URL

https://faezor.ai/mcp

Claude Code: /mcp → faezor → sign in. Apps: Customize → Connectors → Add custom connector, paste the URL, Add, then Connect.

Codex OpenAI · CLI, IDE extension and app

Terminal

codex mcp add faezor --url https://faezor.ai/mcp

or ~/.codex/config.toml

[mcp_servers.faezor]
url = "https://faezor.ai/mcp"

The command opens your browser to sign in; after editing the file, run codex mcp login faezor. The CLI, the IDE extension and the app share the file.

OpenCode Open source · terminal agent

opencode.json

{
  "$schema": "https://opencode.ai/config.json",
  "mcp": {
    "faezor": { "type": "remote", "url": "https://faezor.ai/mcp" }
  }
}

Then opencode mcp auth faezor, or sign in when OpenCode asks on first use.

Muse Meta · Muse Code

~/.config/muse/settings.json

{
  "schema_version": 1,
  "mcpServers": {
    "faezor": {
      "type": "streamable-http",
      "url": "https://faezor.ai/mcp",
      "mode": "optional"
    }
  }
}

Then muse mcp login faezor. With existing settings, add the entry under mcpServers.

Copilot GitHub · Copilot CLI and VS Code

Copilot CLI

copilot mcp add --transport http faezor https://faezor.ai/mcp

.vscode/mcp.json

{
  "servers": {
    "faezor": { "type": "http", "url": "https://faezor.ai/mcp" }
  }
}

Both ask you to sign in when the server first starts.

Needs a free faezor account: your own agent designs the board on faezor's workbench. Create an account

The workbench

What your agent works with.

A router that finishes the job

Gridless and whole-board: differential pairs, length matching and fan-outs included. Written in Rust, and it shows its work live.

A placer with a plan

Places the parts against rules derived from the board and ranks the placements by quick routes.

The checks KiCad does not do

Voltage domains and power budgets, part rules backed by datasheets, netlist = schematic = board, decoupling and power loops, assembly emulation.

faezor's design rules

The same guide and playbooks faezor's own agent follows, so your agent works the way it does.

Open source

Your board, in standard formats.

A plain KiCad project you open, change and order wherever you like. faezor-pcb itself is open source (Apache-2.0): run the whole workbench on your machine with one docker compose up.
