pip install mcp-server-kicad

Or run directly with uvx:

uvx --from mcp-server-kicad mcp-server-kicad-schematic
uvx --from mcp-server-kicad mcp-server-kicad-pcb
uvx --from mcp-server-kicad mcp-server-kicad-symbol

Claude Code Plugin

For Claude Code users, install the plugin to get MCP server configuration and schematic design skills bundled together:

claude plugin marketplace add ProductOfAmerica/mcp-server-kicad
claude plugin install kicad

The plugin automatically configures all five MCP servers and includes skills that teach layout conventions for schematic design. See skills/schematic-design/SKILL.md for details.

Configuration

Add the servers to your Claude Desktop or Claude Code MCP config. Set cwd to your KiCad project directory so the servers can auto-detect project files.

Project Path Resolution

The servers resolve file paths in this order:

1. Auto-detect: Scans the current working directory for a .kicad_pro file and derives schematic, PCB, symbol library, and footprint library paths from it.
2. Environment variables: KICAD_SCH_PATH, KICAD_PCB_PATH, KICAD_SYM_LIB, KICAD_FP_LIB, and KICAD_OUTPUT_DIR override auto-detected values.
3. Tool parameters: Every tool accepts an explicit path parameter that takes highest priority.

Environment Variables

Variable	Description
KICAD_SCH_PATH	Path to .kicad_sch schematic file
KICAD_PCB_PATH	Path to .kicad_pcb PCB file
KICAD_SYM_LIB	Path to .kicad_sym symbol library file
KICAD_FP_LIB	Path to .pretty footprint library directory
KICAD_OUTPUT_DIR	Output directory for exports and reports

System Requirements

• Python 3.10+
• KiCad 9.x -- required for CLI-based tools (ERC, DRC, exports). The kicad-cli binary must be on PATH.
• The schematic and PCB read/write tools use kiutils for file parsing and do not require a KiCad installation.

Debugging

Use the MCP Inspector to test and debug the servers interactively:

npx @modelcontextprotocol/inspector mcp-server-kicad
