feat: Add complete JLCPCB API integration with dual-mode support
Implements full JLCPCB parts catalog integration alongside existing local library search, giving users two complementary approaches for component selection: 1. Local Symbol Libraries (PR #25) - Search JLCPCB libraries installed via KiCad PCM - Pre-configured symbols with footprints - Works offline, no API needed 2. JLCPCB API Integration (NEW) - Complete 100k+ parts catalog access - Real-time pricing and stock information - Basic/Extended library type identification - Cost optimization and alternative suggestions - Package-to-footprint mapping New Features: - download_jlcpcb_database: Download complete parts catalog to local SQLite DB - search_jlcpcb_parts: Parametric search with pricing, stock, library type filters - get_jlcpcb_part: Detailed part info with price breaks and footprint suggestions - get_jlcpcb_database_stats: Database statistics and status - suggest_jlcpcb_alternatives: Find cheaper/available alternatives Implementation: - Python API client (commands/jlcpcb.py) - JLCPCB API authentication and data fetching - Parts database manager (commands/jlcpcb_parts.py) - SQLite storage and search - TypeScript MCP tools (tools/jlcpcb-api.ts) - User-facing tool definitions - Comprehensive documentation (docs/JLCPCB_USAGE_GUIDE.md) Database Features: - ~100k parts with descriptions, pricing, stock levels - Full-text search on descriptions and part numbers - Parametric filtering (category, package, manufacturer, library type) - Package-to-footprint mapping for KiCad - Intelligent alternative suggestions Setup Requirements: - JLCPCB_API_KEY and JLCPCB_API_SECRET environment variables - One-time database download (~5-10 minutes, 42MB) - requests library (already in requirements.txt) Benefits: - Cost optimization (identify Basic parts = free assembly) - Real-time stock checking - Complete catalog access - Works offline after initial download - Complements local library search 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

# JLCPCB Integration Guide
|
||||||
|
|
||||||
|
The KiCAD MCP Server provides **two complementary approaches** for working with JLCPCB parts:
|
||||||
|
|
||||||
|
1. **Local Symbol Libraries** - Search JLCPCB libraries installed via KiCad PCM
|
||||||
|
2. **JLCPCB API Integration** - Access the complete 100k+ parts catalog with real-time pricing
|
||||||
|
|
||||||
|
Both approaches can be used together to give you maximum flexibility.
|
||||||
|
|
||||||

|
||||||
|
|
||||||
|
## Approach 1: Local Symbol Libraries (Recommended for Getting Started)
|
||||||
|
|
||||||
|
### What It Does
|
||||||
|
- Searches symbol libraries you've installed via KiCad's Plugin and Content Manager (PCM)
|
||||||
|
- Works with community JLCPCB libraries like `JLCPCB-KiCad-Library`
|
||||||
|
- No API credentials needed
|
||||||
|
- Works offline
|
||||||
|
- Symbols already have LCSC IDs and footprints configured
|
||||||
|
|
||||||
|
### Setup
|
||||||
|
|
||||||
|
1. **Install JLCPCB Libraries via KiCad PCM:**
|
||||||
|
- Open KiCad → Tools → Plugin and Content Manager
|
||||||
|
- Search for "JLCPCB" or "JLC"
|
||||||
|
- Install libraries like:
|
||||||
|
- `JLCPCB-KiCad-Library` (community maintained)
|
||||||
|
- `EDA_MCP` (contains common JLCPCB parts)
|
||||||
|
- Any other JLCPCB-compatible libraries
|
||||||
|
|
||||||
|
2. **Verify Installation:**
|
||||||
|
The libraries should appear in KiCad's symbol library table.
|
||||||
|
|
||||||
|
### Usage Examples
|
||||||
|
|
||||||
|
#### Search for Components
|
||||||
|
```
|
||||||
|
search_symbols({
|
||||||
|
query: "ESP32",
|
||||||
|
library: "JLCPCB" // Filter to JLCPCB libraries only
|
||||||
|
})
|
||||||
|
```
|
||||||
|
|
||||||
|
Returns:
|
||||||
|
```
|
||||||
|
Found 12 symbols matching "ESP32":
|
||||||
|
|
||||||
|
PCM_JLCPCB-MCUs:ESP32-C3 | LCSC: C2934196 | ESP32-C3 RISC-V WiFi/BLE SoC
|
||||||
|
PCM_JLCPCB-MCUs:ESP32-S2 | LCSC: C701342 | ESP32-S2 WiFi SoC
|
||||||
|
...
|
||||||
|
```
|
||||||
|
|
||||||
|
#### Search by LCSC ID
|
||||||
|
```
|
||||||
|
search_symbols({
|
||||||
|
query: "C2934196" // Direct LCSC ID search
|
||||||
|
})
|
||||||
|
```
|
||||||
|
|
||||||
|
#### Get Symbol Details
|
||||||
|
```
|
||||||
|
get_symbol_info({
|
||||||
|
symbol: "PCM_JLCPCB-MCUs:ESP32-C3"
|
||||||
|
})
|
||||||
|
```
|
||||||
|
|
||||||
|
Returns:
|
||||||
|
```
|
||||||

## Approach 2: JLCPCB API Integration (For Complete Catalog Access)
|
||||||
|
|
||||||
|
### What It Does
|
||||||
|
- Downloads the **complete JLCPCB parts catalog** (~100k+ parts)
|
||||||
|
- Provides **real-time pricing and stock information**
|
||||||
|
- Automatic **Basic vs Extended** library type identification (Basic = free assembly)
|
||||||
|
- Smart suggestions for cheaper/in-stock alternatives
|
||||||
|
- Package-to-footprint mapping for KiCad
|
||||||
|
|
||||||
|
### Setup
|
||||||
|
|
||||||
|
#### 1. Get JLCPCB API Credentials
|
||||||
|
|
||||||
|
Visit [JLCPCB](https://jlcpcb.com/) and get your API credentials:
|
||||||
|
1. Log in to your JLCPCB account
|
||||||
|
2. Go to: **Account → API Management**
|
||||||
|
3. Click "Create API Key"
|
||||||
|
4. Save your `appKey` and `appSecret`
|
||||||
|
|
||||||
|
#### 2. Configure Environment Variables
|
||||||
|
|
||||||
|
Add to your shell profile (`~/.bashrc`, `~/.zshrc`, or `~/.profile`):
|
||||||
|
|
||||||
|
```bash
|
||||||
|
export JLCPCB_API_KEY="your_app_key_here"
|
||||||
|
export JLCPCB_API_SECRET="your_app_secret_here"
|
||||||
|
```
|
||||||
|
|
||||||
|
Or create a `.env` file in the project root:
|
||||||
|
|
||||||
|
```
|
||||||
|
JLCPCB_API_KEY=your_app_key_here
|
||||||
|
JLCPCB_API_SECRET=your_app_secret_here
|
||||||
|
```
|
||||||
|
|
||||||
|
#### 3. Download the Parts Database
|
||||||
|
|
||||||
|
**One-time setup** (takes 5-10 minutes):
|
||||||
|
|
||||||
|
```
|
||||||
|
download_jlcpcb_database({ force: false })
|
||||||
|
```
|
||||||
|
|
||||||
|
This downloads ~100k parts from JLCPCB and creates a local SQLite database (`data/jlcpcb_parts.db`).
|
||||||
|
|
||||||
|
**Output:**
|
||||||
|

## Best Practices: Using Both Approaches Together
|
||||||
|
|
||||||
|
### Workflow 1: Design with Known Components
|
||||||
|
|
||||||
|
**Use Local Libraries:**
|
||||||
|
```
|
||||||
|
1. search_symbols({ query: "STM32F103", library: "JLCPCB" })
|
||||||
|
2. Select component from installed library
|
||||||
|
3. Component already has correct symbol + footprint + LCSC ID
|
||||||
|
```
|
||||||
|
|
||||||
|
**Why:** Faster, symbols are pre-configured and tested.
|
||||||
|
|
||||||
|
### Workflow 2: Find Optimal Part for Cost
|
||||||
|
|
||||||
|
**Use JLCPCB API:**
|
||||||
|
```
|
||||||
|
1. search_jlcpcb_parts({
|
||||||
|
query: "10k resistor",
|
||||||
|
package: "0603",
|
||||||
|
library_type: "Basic"
|
||||||
|
})
|
||||||
|
2. Select cheapest Basic part
|
||||||
|
3. Use suggested footprint from API
|
||||||
|
```
|
||||||
|
|
||||||
|
**Why:** Ensures lowest cost and maximum stock availability.
|
||||||
|
|
||||||
|
### Workflow 3: Explore Unknown Parts
|
||||||
|
|
||||||
|
**Start with API, verify with Libraries:**
|
||||||
|
```
|
||||||
|
1. search_jlcpcb_parts({ query: "ESP32", limit: 20 })
|
||||||
|
2. Find interesting part (e.g., C2934196)
|
||||||
|
3. search_symbols({ query: "C2934196" })
|
||||||
|
4. If found in library → use library symbol
|
||||||
|
5. If not found → use API footprint suggestion
|
||||||
|
```
|
||||||
|
|
||||||
|
**Why:** Combines discovery power of API with quality of curated libraries.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Cost Optimization Tips
|
||||||
|
|
||||||
|
### 1. Prefer Basic Parts
|
||||||
|
|
||||||
|
```
|
||||||
|
search_jlcpcb_parts({
|
||||||
|
query: "resistor 10k",
|
||||||
|
library_type: "Basic" // Free assembly!
|
||||||
|
})
|
||||||
|
```
|
||||||
|
|
||||||
|
**Why:** Basic parts have **$0 assembly fee**. Extended parts charge **$3 per unique part**.
|
||||||
|
|
||||||
|
### 2. Use Alternatives Tool
|
||||||
|
|
||||||
|
```
|
||||||
|
suggest_jlcpcb_alternatives({ lcsc_number: "C12345" })
|
||||||
|
```
|
||||||
|
|
||||||
|
**Why:** Find cheaper, more available, or Basic alternatives automatically.
|
||||||
|
|
||||||
|
### 3. Check Stock Levels
|
||||||
|
|
||||||
|
Always filter `in_stock: true` to avoid ordering parts that are out of stock:
|
||||||
|
|
||||||
|
```
|
||||||
|
search_jlcpcb_parts({
|
||||||
|
query: "capacitor",
|
||||||
|
in_stock: true // Only show available parts
|
||||||
|
})
|
||||||
|
```
|
||||||
|
|
||||||
|
### 4. Calculate BOM Cost
|
||||||
|
|
||||||
|
For each part in your design:
|
||||||
|
1. Use `get_jlcpcb_part()` to get price breaks
|
||||||
|
2. Sum up total cost based on order quantity
|
||||||
|
3. Check library_type count (each unique Extended part = $3 fee)
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Updating the Database
|
||||||
|
|
||||||
|
The JLCPCB parts database should be updated periodically to get latest parts and pricing.
|
||||||
|
|
||||||
|
### Manual Update
|
||||||
|
|
||||||
|
```
|
||||||
|
download_jlcpcb_database({ force: true })
|
||||||
|
```
|
||||||
|
|
||||||
|
This re-downloads the entire catalog and replaces the existing database.
|
||||||
|
|
||||||
|
### Automatic Updates (Future)
|
||||||
|
|
||||||
|
Future versions will support incremental updates that only fetch new/changed parts.
|
||||||
|
|
||||||

||||||
|
## Troubleshooting
|
||||||
|
|
||||||
|
### "JLCPCB API credentials not configured"
|
||||||
|
|
||||||
|
**Solution:** Set environment variables:
|
||||||
|
```bash
|
||||||
|
export JLCPCB_API_KEY="your_key"
|
||||||
|
export JLCPCB_API_SECRET="your_secret"
|
||||||
|
```
|
||||||
|
|
||||||
|
### "Database not found or empty"
|
||||||
|
|
||||||
|
**Solution:** Run:
|
||||||
|
```
|
||||||
|
download_jlcpcb_database({ force: false })
|
||||||
|
```
|
||||||
|
|
||||||
|
### "No symbols found" (Local Libraries)
|
||||||
|
|
||||||
|
**Solution:**
|
||||||
|
1. Install JLCPCB libraries via KiCad PCM
|
||||||
|
2. Verify library is enabled in KiCad symbol library table
|
||||||
|
3. Restart KiCad MCP server
|
||||||
|
|
||||||
|
### "Authentication failed"
|
||||||
|
|
||||||
|
**Solution:**

||||||
|
1. Verify your API credentials are correct
|
||||||
|
2. Check JLCPCB account has API access enabled
|
||||||
|
3. Try regenerating API key/secret in JLCPCB dashboard

## Example Workflows
|
||||||
|
|
||||||
|
### Complete Design Flow
|
||||||
|
|
||||||
|
```
|
||||||
|
# 1. Find main MCU from local library (curated)
|
||||||
|
search_symbols({ query: "ESP32", library: "JLCPCB" })
|
||||||
|
→ Use: PCM_JLCPCB-MCUs:ESP32-C3
|
||||||
|
|
||||||
|
# 2. Find passives optimized for cost (API)
|
||||||
|
search_jlcpcb_parts({
|
||||||
|
query: "capacitor 10uF",
|
||||||
|
package: "0805",
|
||||||
|
library_type: "Basic"
|
||||||
|
})
|
||||||
|
→ Use: C15850 ($0.004, Basic, 80k stock)
|
||||||
|
|
||||||
|
# 3. Verify connector in library
|
||||||
|
search_symbols({ query: "USB-C" })
|
||||||
|
→ Use library symbol if available
|
||||||
|
|
||||||
|
# 4. Export BOM with LCSC numbers
|
||||||
|
# All components now have LCSC IDs for JLCPCB assembly!
|
||||||
|
```

## Summary
|
||||||
|
|
||||||
|
**Use Local Libraries when:**
|
||||||
|
- Starting a new design with common components
|
||||||
|
- You want pre-configured, tested symbols
|
||||||
|
- Working offline
|
||||||
|
- Components are in installed libraries
|
||||||
|
|
||||||
|
**Use JLCPCB API when:**
|
||||||
|
- Optimizing cost (find cheapest Basic parts)
|
||||||
|
- Checking real-time stock availability
|
||||||
|
- Exploring parts outside installed libraries
|
||||||
|
- Need complete catalog access
|
||||||
|
|
||||||
|
**Best approach:** Use both! Start with local libraries for known components, then use API for cost optimization and finding alternatives.
