Security Report

4.2
Use Caution4.2High Risk

EasyEDA Copilot MCP server is a well-structured circuit design tool with legitimate network and file I/O permissions matching its purpose. The codebase is minified/obfuscated in production builds (the autorouter worker), which complicates security review, but no confirmed malicious patterns or data exfiltration were detected. Permissions appropriately align with a developer tool category (network_http, file_read/write). Low-severity findings include missing input validation in some paths and broad exception handling that could mask errors. Supply chain analysis found 9 known vulnerabilities in dependencies (0 critical, 1 high severity). Package verification found 1 issue (1 critical, 0 high severity).

Security scores are indicators to help you make informed decisions, not guarantees. Always review permissions before connecting any MCP server.

Permissions Required

This plugin requests these system permissions. Most are normal for its category.

HTTP Network Access

Connects to external APIs or services over the internet.

network_websocket

Check that this permission is expected for this type of plugin.

File System Read

Reads files on your machine. Normal for tools that analyze or process local data.

File System Write

Writes or modifies files on your machine. Check that this is expected for the tool.

env_vars

Check that this permission is expected for this type of plugin.

Unverified package source

EasyEDA Copilot

AI-powered assistant for EasyEDA Pro and JLCEDA. Generate schematics from natural language, complete existing circuits, search LCSC components by requirements, run SPICE simulations, and reuse proven circuit blocks directly inside your EDA workflow.

What it does

EasyEDA Copilot adds an AI design layer to EasyEDA Pro:

  • Generate circuits from text: describe the circuit you need and let the agent assemble a schematic proposal.
  • Complete existing schematics: attach selected circuit fragments and ask Copilot to add, replace or connect parts.
  • Search LCSC components: find parts from natural-language requirements and electrical characteristics.
  • Use reusable blocks: insert reviewed standard subcircuits such as regulators, interfaces and protection blocks.
  • Explain and analyze circuits: discuss schematic behavior, signal flow and design tradeoffs.
  • Run SPICE simulations: simulate supported circuits and inspect selected models before trusting the result.
  • Design PCBs through MCP: generate placement, assemble the board, route it, inspect results, and run DRC from an MCP client.

More examples are available on Oshwlab.

Installation

Download the latest .eext package from Releases.

In EasyEDA Pro:

  1. Open Settings -> Extensions -> Extensions Manager.
  2. Click Import Extensions.
  3. Select the downloaded .eext file.
  4. Enable External Interactions.
  5. Open a schematic and use Copilot -> Interface.

MCP server

EasyEDA Copilot can connect to external MCP clients. The extension scans ws://127.0.0.1:8787 every 5 seconds and connects when your MCP server is available. The Copilot -> MCP menu item pauses or resumes this scan.

Codex:

codex mcp add easyeda-copilot -- npx easyeda-copilot-mcp

Claude Code:

claude mcp add easyeda-copilot -- npx easyeda-copilot-mcp

Recommended order:

  1. Add the MCP server to your agent.
  2. Start Codex, Claude Code, or another MCP client with this MCP server enabled.
  3. Open a schematic in EasyEDA Pro.
  4. EasyEDA Copilot will connect automatically. Use Copilot -> MCP only to pause or resume scanning.

See MCP package README

PCB Workflow (MCP only)

PCB placement is available only through an external MCP client such as Codex or Claude Code. It is not available in the built-in Copilot chat.

MCP creates placement: board outline, mechanical constraints, components, mounting holes, board pads, and designator positions. Review the mechanical preview first, approve the final placement, then import it into EasyEDA. After assembly, MCP can run its bundled auto-router, inspect PCB objects, and invoke EasyEDA DRC on the open Desktop document.

PCB assembly, preview, and client routing support are verified with EasyEDA Desktop V3.2.149.

Features

Circuit generation

Generate schematics from natural-language descriptions. Copilot can plan the circuit, search components, create a structured result and expose an Assemble circuit action when the generated schematic is ready.

Circuit completions

Use Copilot on an existing schematic fragment. Ask it to complete a missing block, add components, connect signals or propose changes based on selected circuit context.

Component selection

Search LCSC by intent instead of manually tuning catalog filters. Examples:

  • find 5V relay
  • Find DC-DC chip 5V and 10A current
  • find capacitor 22uF Murata SMD 1210

Reusable blocks

Reusable blocks are reviewed schematic fragments that the agent can adapt and insert into generated circuits. They are useful for standard subcircuits where the topology stays stable and only ports or passive values change.

See Reusable blocks documentation.

SPICE simulation

Copilot can run SPICE simulations and automatically select models from a component model library.

Always verify the SPICE models used for replacement components. The selected models are shown below the graph after simulation.
