JLCPCB API & MCP Integration

Research on available tools to integrate JLCPCB services directly into the Claude Code workflow.

LCSC-MCP-Server

Repository: mageoch/LCSC-MCP-Server
Last updated: 2026-03-26
Status: Functional, early stage (0 stars)

MCP server for searching LCSC/JLCPCB parts with live API access.

Features

• Parametric search for passives (R, C, L) by value, package, tolerance
• Free-text search across 2.5M+ parts
• Real-time pricing and stock availability
• Basic vs Extended part classification (impacts JLCPCB assembly cost)
• KiCad symbol, footprint, and 3D model download
• Local SQLite cache for fast repeated queries

Setup

1. Register at JLCPCB Developer Portal
2. Obtain credentials: JLCPCB_APP_ID, JLCPCB_API_KEY, JLCPCB_API_SECRET
3. Add to .mcp.json:

{
  "mcpServers": {
    "lcsc": {
      "command": "node",
      "args": ["path/to/lcsc-mcp-server/dist/index.js"],
      "env": {
        "JLCPCB_APP_ID": "...",
        "JLCPCB_API_KEY": "...",
        "JLCPCB_API_SECRET": "..."
      }
    }
  }
}

Integration with ESP32 Emu Turbo

• Replaces manual LCSC lookups in the /jlcpcb-parts skill
• Enables the pcb-engineer agent to query live stock and pricing
• Can verify Basic/Extended status before BOM finalization
• Potential to auto-download KiCad footprints for new components

JLCPCB API Documentation

Repository: Jackster/JLCPCB-API
Last updated: 2026-02-16
Status: Documentation only (no server)

Reverse-engineered documentation of the JLCPCB Overseas OpenAPI endpoints.

Available Endpoints

Endpoint	Description
PCB Price Calculation	Get instant quotes for PCB fabrication
Gerber Upload	Upload gerber files for order creation
Order Creation	Place PCB/PCBA orders programmatically
Order Tracking	Check order status and shipping info

Authentication

Uses HMAC-SHA256 signing with app credentials. Python examples provided in the repository.

Potential Skills

Skill	Description
/jlcpcb-quote	Get instant price for current gerbers without leaving the CLI
/jlcpcb-order	Upload gerbers and place an order directly
/jlcpcb-track	Check order status from the terminal

Next Steps

1. Register for JLCPCB Developer Portal API access
2. Install LCSC-MCP-Server and add to .mcp.json
3. Test part search queries against our BOM components
4. Evaluate building a pricing/ordering MCP server using the JLCPCB-API docs
