A Model Context Protocol (MCP) server that enables AI assistants like Claude to interact with KiCAD for PCB design automation. Built on the MCP 2025-06-18 specification, this server provides comprehensive tool schemas and real-time project state access for intelligent PCB design workflows.

The Model Context Protocol is an open standard from Anthropic that allows AI assistants to securely connect to external tools and data sources. This implementation provides a standardized bridge between AI assistants and KiCAD, enabling natural language control of PCB design operations.

Key Capabilities:

• 64 fully-documented tools with JSON Schema validation
• Smart tool discovery with router pattern (reduces AI context by 70%)
• 8 dynamic resources exposing project state
• JLCPCB parts integration with 2.5M+ component catalog and local library search
• Full MCP 2025-06-18 protocol compliance
• Cross-platform support (Linux, Windows, macOS)
• Real-time KiCAD UI integration via IPC API (experimental)
• Comprehensive error handling and logging

The schematic workflow was completely broken in previous versions - this is now fixed AND dramatically enhanced!

What was broken:

• create_project only created PCB files, no schematics
• add_schematic_component called non-existent API methods
• Schematics couldn't be created or edited at all
• Only 13 component types available (severe limitation)
• No working wire/connection functionality

Complete Implementation (3 Phases):

Phase 1: Component Placement Foundation

• create_project now creates both .kicad_pcb and .kicad_sch files
• Added pre-configured template schematics with 13 common component types
• Rewrote component placement to use proper clone() API

Phase 2: Dynamic Symbol Loading (BREAKTHROUGH!)

• Access to ALL ~10,000 KiCad symbols from standard libraries
• Automatic detection and dynamic loading from .kicad_sym library files
• Zero configuration required - just specify library and symbol name
• Seamless integration with existing MCP tools
• Full S-expression parsing and injection system

Phase 3: Intelligent Wiring System (NEW in v2.1.0)

• Automatic pin location discovery with rotation support (0°, 90°, 180°, 270°)
• Smart wire routing (direct, orthogonal horizontal-first, orthogonal vertical-first)
• Power symbol support (VCC, GND, +3V3, +5V, etc.)
• Wire graph analysis - geometric tracing for net connectivity
• Net label management (local, global, hierarchical labels)
• Netlist generation with accurate component/pin connections

Technical Architecture: The kicad-skip library cannot create symbols or wires from scratch. We implemented a comprehensive solution:

1. Static Templates: 13 pre-configured symbols (R, C, L, LED, etc.) for instant use
2. Dynamic Loading: On-demand injection of ANY symbol from KiCad libraries:
   • Parse .kicad_sym library files using S-expression parser
   • Inject symbol definition into schematic's lib_symbols section
   • Create offscreen template instance
   • Reload schematic so kicad-skip sees new template
   • Clone template to create actual component
3. Wire Creation: S-expression-based wire injection (bypasses kicad-skip API limitations)
4. Pin Discovery: Parse symbol definitions, apply rotation transformations, calculate absolute positions
5. Connectivity Analysis: Geometric wire tracing to build net connection graphs

Example - Complete Circuit Creation:

# Load power symbols dynamically
loader.load_symbol_dynamically(sch_path, "power", "VCC")

# Place components with auto-rotation
ComponentManager.add_component(sch, {
    "type": "STM32F103C8Tx",
    "library": "MCU_ST_STM32F1",
    "reference": "U1",
    "x": 100, "y": 100, "rotation": 0
})

# Connect with intelligent routing
ConnectionManager.add_connection(sch_path, "U1", "1", "R1", "2", routing="orthogonal_h")

# Connect to power nets
ConnectionManager.connect_to_net(sch_path, "U1", "VDD", "VCC")

# Analyze connectivity
connections = ConnectionManager.get_net_connections(sch, "VCC", sch_path)
# Returns: [{"component": "U1", "pin": "VDD"}, {"component": "R1", "pin": "1"}]

Test Results:

• Component placement: 100% passing
• Dynamic symbol loading: 10,000+ symbols accessible
• Wire creation: 100% passing (8/8 connections in test circuit)
• Pin discovery: Rotation-aware, sub-millimeter accuracy
• Net connectivity: 100% accurate (VCC: 2 connections, GND: 4 connections)
• Netlist generation: Working with accurate pin-level connections

See Dynamic Loading Status and Wiring Implementation Plan for technical details.

We are currently implementing and testing the KiCAD 9.0 IPC API for real-time UI synchronization:

• Changes made via MCP tools appear immediately in the KiCAD UI
• No manual reload required when IPC is active
• Hybrid backend: uses IPC when available, falls back to SWIG API
• 20+ commands now support IPC including routing, component placement, and zone operations

Note: IPC features are under active development and testing. Enable IPC in KiCAD via Preferences > Plugins > Enable IPC API Server.

We've implemented an intelligent tool router to keep AI context efficient while maintaining full functionality:

• 12 direct tools always visible for high-frequency operations
• 47 routed tools organized into 7 categories (board, component, export, drc, schematic, library, routing)
• 4 router tools for discovery and execution:
  • list_tool_categories - Browse all available categories
  • get_category_tools - View tools in a specific category
  • search_tools - Find tools by keyword
  • execute_tool - Run any tool with parameters

Why this matters: By organizing tools into discoverable categories, Claude can intelligently find and use the right tool for your task without loading all 64 tool schemas into every conversation. This reduces context consumption by up to 70% while maintaining full access to all functionality.

Usage is seamless: Just ask naturally - "export gerber files" or "add mounting holes" - and Claude will discover and execute the appropriate tools automatically.

Complete integration with JLCPCB's parts catalog, providing two complementary approaches for component selection:

Dual-Mode Architecture:

1. Local Symbol Libraries - Search JLCPCB libraries installed via KiCAD Plugin and Content Manager (contributed by @l3wi)
2. JLCPCB API Integration - Access the complete 2.5M+ parts catalog with real-time pricing and stock data

Key Features:

• Real-time pricing with quantity breaks (1+, 10+, 100+, 1000+)
• Stock availability checking
• Basic vs Extended library type identification (Basic = free assembly)
• Intelligent cost optimization with alternative part suggestions
• Package-to-footprint mapping for KiCAD compatibility
• Parametric search by category, package, manufacturer
• Local SQLite database for fast offline searching
• No API credentials required for local library search

Why this matters: JLCPCB offers PCB assembly services where Basic parts have no assembly fee, while Extended parts charge $3 per unique component. This integration helps you find the cheapest components with the best availability, potentially saving hundreds of dollars on assembly costs for production runs.

See JLCPCB Usage Guide for detailed setup and usage instructions.

Every tool now includes complete JSON Schema definitions with:

• Detailed parameter descriptions and constraints
• Input validation with type checking
• Required vs. optional parameter specifications
• Enumerated values for categorical inputs
• Clear documentation of what each tool does

Access project state without executing tools:

• kicad://project/current/info - Project metadata
• kicad://project/current/board - Board properties
• kicad://project/current/components - Component list (JSON)
• kicad://project/current/nets - Electrical nets
• kicad://project/current/layers - Layer stack configuration
• kicad://project/current/design-rules - Current DRC settings
• kicad://project/current/drc-report - Design rule violations
• kicad://board/preview.png - Board visualization (PNG)

• Updated to MCP SDK 1.21.0 (latest)
• Full JSON-RPC 2.0 support
• Proper capability negotiation
• Standards-compliant error codes

The server provides 64 tools organized into functional categories. With the new router pattern, tools are automatically discovered as needed - just ask Claude what you want to accomplish!

# Clone and build
git clone https://github.com/mixelpixx/KiCAD-MCP-Server.git
cd KiCAD-MCP-Server
npm install
pip3 install -r requirements.txt
npm run build

Edit configuration file:

• Linux/macOS: ~/.config/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json

Configuration:

{
  "mcpServers": {
    "kicad": {
      "command": "node",
      "args": ["/path/to/KiCAD-MCP-Server/dist/index.js"],
      "env": {
        "PYTHONPATH": "/path/to/kicad/python",
        "LOG_LEVEL": "info"
      }
    }
  }
}

Platform-specific PYTHONPATH:

• Linux: /usr/lib/kicad/lib/python3/dist-packages
• Windows: C:\Program Files\KiCad\9.0\lib\python3\dist-packages
• macOS: /Applications/KiCad/KiCad.app/Contents/Frameworks/Python.framework/Versions/3.11/lib/python3.11/site-packages

The server automatically detects Python on Linux in this priority order:

1. Virtual environment - venv/bin/python or .venv/bin/python (highest priority)
2. KICAD_PYTHON env var - User override for non-standard installations
3. KiCad bundled Python - /usr/lib/kicad/bin/python3, /usr/local/lib/kicad/bin/python3, /opt/kicad/bin/python3
4. System Python via which - Resolves which python3 to absolute path (e.g., /usr/bin/python3)
5. Common system paths - /usr/bin/python3, /bin/python3

For most standard Linux installations (Ubuntu, Debian, Fedora, Arch), no KICAD_PYTHON configuration is needed - the server will automatically find your Python installation.

Troubleshooting:

If you see "Python executable not found: python3", you can manually specify the Python path:

{
  "mcpServers": {
    "kicad": {
      "command": "node",
      "args": ["/path/to/KiCAD-MCP-Server/dist/index.js"],
      "env": {
        "KICAD_PYTHON": "/usr/bin/python3",
        "PYTHONPATH": "/usr/lib/kicad/lib/python3/dist-packages"
      }
    }
  }
}

To find your Python path:

which python3  # Example output: /usr/bin/python3
python3 -c "import pcbnew; print(pcbnew.GetBuildVersion())"  # Verify pcbnew access

Edit: ~/.config/Code/User/globalStorage/saoudrizwan.claude-dev/settings/cline_mcp_settings.json

Use the same configuration format as Claude Desktop above.

Claude Code automatically detects MCP servers in the current directory. No additional configuration needed.

The JLCPCB integration provides two modes that can be used independently or together:

Mode 1: JLCSearch Public API (Recommended - No Setup Required)

The easiest way to access JLCPCB's parts catalog:

• No API credentials needed
• No JLCPCB account required
• Access to 2.5M+ parts with pricing and stock data
• Download time: 40-60 minutes for full catalog (100-part batches due to API limit)

To download the database:

Ask Claude: "Download the JLCPCB parts database"

This creates a local SQLite database at data/jlcpcb_parts.db (~1-2 GB for full catalog).

Mode 2: Local Symbol Libraries (No Setup Required)

Install JLCPCB libraries via KiCAD's Plugin and Content Manager:

1. Open KiCAD
2. Go to Tools > Plugin and Content Manager
3. Search for "JLCPCB" or "JLC"
4. Install libraries like JLCPCB-KiCAD-Library or EDA_MCP
5. Use search_symbols to find components with pre-configured footprints and LCSC IDs

Mode 3: Official JLCPCB API (Advanced - Requires Enterprise Account)

For users with JLCPCB enterprise accounts and order history:

1. Get API Credentials

   • Log in to JLCPCB
   • Navigate to Account > API Management (requires enterprise approval)
   • Create API Key and save your appKey and appSecret
   • Note: This requires prior order history and enterprise account approval

2. Configure Environment Variables

   Add to your shell profile (~/.bashrc, ~/.zshrc, or ~/.profile):

   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
   

See JLCPCB Usage Guide for detailed documentation.
