What it does
easyeda-agent gives an agent hands inside EasyEDA Pro, the professional edition of the JLC EDA design tool. It has three parts: the easyeda command with a local daemon, the EDA Agent Connector extension inside the editor and a skill for Claude Code or Codex. The agent does not click the interface. It calls typed actions through the editor's official API and, before and after each write, checks component identity, pin nets, geometry and save state. The set covers the whole path from requirement to board. From a datasheet PDF and a package drawing the agent creates a Symbol, Footprint and Device, with an optional 3D model, and checks the pin-to-pad mapping. From a text brief it picks components, draws the schematic, places modules, draws the outline, the layer stack, routing, copper pours and silkscreen, then runs DRC and manufacturing checks. Non-standard schematic parts can be swapped for standard ones by LCSC number while keeping designators. On top of that sit a library of ready circuit blocks (CH340, ESP32 auto-download, buttons, a USB hub, a buck converter), BOM, netlist and manufacturing exports, an audit log and explicit saving. After a partial success or a timeout the agent first reads the project state back and only then decides what to do next.
Who it is for. For electronics engineers who design boards in EasyEDA Pro and want an agent to take over routine work: libraries, placement, routing, silkscreen and checks.
Good fit when
- You have a chip datasheet PDF and need a Symbol, Footprint and Device built from it, with the pin-to-pad mapping verified
- You need a small board from requirements, such as an ESP32-S3 with 3V3 power, CH340, BOOT and RESET buttons and four layers with an antenna keepout
- A schematic mixes non-standard parts and you need to swap them for standard ones by LCSC number, keeping designators and showing pin differences
- Silkscreen labels collide on a board and need cleaning up: no overlaps with pads, the board edge or each other
- Before handing a board to manufacturing you want one pass: schematic checks, board DRC, BOM, netlist and order files
Not a fit when
- You work in KiCad, Altium or another CAD tool: the set drives only EasyEDA Pro through its extension
- You need a dense board routed end to end: the built-in router suits short, clear connections, and maze routing needs external Freerouting
- You need controlled-impedance calculations: dielectric thickness, permittivity and copper weight are not readable through the editor API, and the set does not claim impedance as met
- You need a manufacturing-ready guarantee: the developer stresses that example results do not replace checks on a real assembly
Example request
Use easyeda-agent: check the current board, find silkscreen labels that overlap pads or cross the outline, fix them, run DRC and save the projectLimitations
- Requires EasyEDA Pro V4 (V4.1.60 is the verified version, that or newer is recommended) and the external interaction option switched on in settings. `easyeda health` reports the state.
- Dense boards need external Freerouting. The built-in router targets short connections and local stretches.
- The editor API has no programmatic undo. The project softens the consequences with pre-write checks, readback and rollback on failure.
- Data for controlled impedance is not readable, so the set does not claim impedance as met.
- Library building from a PDF stops and asks when the scan is blurry, the package suffix is unclear or pad data is missing.
- The AS07 example was built from a drawing rather than a full manufacturer PDF; assembly, a placed instance and DRC were not verified, as the developer states.
How to disable. Disable the EDA Agent Connector extension in the EasyEDA Pro extension manager and switch off the external interaction option. Delete the skill folder from the Claude Code or Codex skills directory and remove the easyeda-agent entry from the MCP settings. The easyeda binary sits in `~/.local/bin` (on Windows `%USERPROFILE%\.local\bin`), the daemon starts on demand and its log lives in `~/.easyeda-agent/daemon.log`. The variable `EASYEDA_NO_AUTOSTART=1` turns auto-start off.
FAQ
How do I connect easyeda-agent to Claude Code or Codex?
Run the install.sh or install.ps1 script: it verifies SHA-256 checksums, installs the easyeda command and the skill, and recognizes Codex, Codex Desktop and Claude Code. Then install the EDA Agent Connector extension from the JLC market, switch on external interaction in EasyEDA Pro and run `easyeda health`.
Can AI design a PCB in EasyEDA Pro?
The agent covers the path from requirements to a board: schematic, placement, outline, layers, routing, copper, silkscreen, DRC and saving. The repository has an ESP32-S3 four-layer example. Manufacturing readiness has to be checked separately.
How do I build a component library from a datasheet?
Give the agent the PDF and the full part number. It checks for an exact match in the EasyEDA and LCSC libraries, then runs `easyeda lib device validate --spec` to check datasheet evidence and `lib device build`, which creates the Symbol, Footprint and Device in your personal library. It asks a question if the package is unclear or dimensions are missing.
Does easyeda-agent have an MCP server?
Yes, a local stdio MCP adapter with 12 tools: connection health, action discovery, one tool for each of seven safe domains, circuit blocks, a guarded workflow and project transfer. The arbitrary-JavaScript domain is deliberately not exposed in MCP. For Codex the server registers with `codex mcp add easyeda-agent`, giving EASYEDA_BIN and the path to `mcp/src/server.mjs`.
What checks does the agent make when writing to a project?
Before a write the agent verifies the target project, page, component identity and source data, and afterward reads back pins, nets, geometry and object bindings. Schematics go through layout-lint, check, bridge-check and DRC. Autosave serves as a safety net, and key steps are saved explicitly.

README in short
The repository front page opens with a table of scenarios, from building a library from a PDF to releasing a board and its checks, and example prompts for the agent. Results in practice follow: a personal library from a module drawing, a learning Layout with 69 components, a four-layer ESP32-S3 board and connection-driven schematic data. Installation takes three steps: the CLI with the skill, the connector extension and a check with easyeda health. The end describes the limits of what the set can do, documentation links and how to contribute.
