Configuration

Docker Desktop MCP Integration

This method uses Docker Desktop's built-in MCP extension for the easiest setup experience.

Prerequisites

  • Docker Desktop 4.39.0+ installed and running

  • Claude Desktop installed

Setup Steps

  1. Install Docker Desktop Extension:

    • Launch Docker Desktop

    • Go to "Extensions" from the left menu

    • Search for "AI Tools" or "Docker MCP Toolkit"

    • Install "Labs: AI Tools for Devs" extension

  2. Configure Docker MCP Connection:

    • Open the installed "Labs: AI Tools for Devs" extension

    • Click the gear icon in the upper right corner

    • Select the "MCP Clients" tab

    • Click "Connect" for "Claude Desktop" or "Cursor IDE"

    This automatically configures Claude Desktop and Cursor IDE with:

    { "mcpServers": { "MCP_DOCKER": { "command": "docker", "args": [ "run", "-i", "--rm", "alpine/socat", "STDIO", "TCP:host.docker.internal:8811" ] } } }

Cursor IDE Setup

  1. Add Your EDA MCP Server:

    • Locate your Claude Desktop config file, Settings > Developer > Edit Config:

      • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

      • Windows: %APPDATA%\Claude\claude_desktop_config.json

    • Add your EDA server to the existing configuration:

    { "mcpServers": { "MCP_DOCKER": { "command": "docker", "args": [ "run", "-i", "--rm", "alpine/socat", "STDIO", "TCP:host.docker.internal:8811" ] }, "eda-mcp": { "command": "node", "args": [ "/absolute/path/to/your/eda-mcp-server/build/index.js" ], "env": { "PATH": "/usr/local/bin:/opt/homebrew/bin:/usr/bin:/bin", "HOME": "/your/home/directory" } } } }

  2. Restart Claude Desktop and verify both servers are running in Settings > Developer.

Cursor IDE Setup

  1. Open Cursor Settings:

    • Press Ctrl + Shift + P (Windows/Linux) or Cmd + Shift + P (macOS)

    • Search for "Cursor Settings"

    • Navigate to "MCP" in the sidebar

  2. Add MCP Server: Click "Add new MCP server" and configure:

    { "mcpServers": { "MCP_DOCKER": { "command": "docker", "args": [ "run", "-i", "--rm", "alpine/socat", "STDIO", "TCP:host.docker.internal:8811" ] }, "eda-mcp": { "command": "node", "args": [ "/absolute/path/to/your/eda-mcp-server/build/index.js" ], "env": { "PATH": "/usr/local/bin:/opt/homebrew/bin:/usr/bin:/bin", "HOME": "/your/home/directory" } } } }

  3. Enable MCP Tools:

    • Go to Cursor Settings → MCP

    • Enable the "eda-mcp" server

    • You should see the server status change to "Connected"

Usage Examples

1. Verilog Synthesis

Ask Claude: "Can you synthesize this counter module for an ice40 FPGA?" module counter( input clk, input rst, output [7:0] count ); reg [7:0] count_reg; assign count = count_reg; always @(posedge clk or posedge rst) begin if (rst) count_reg <= 8'b0; else count_reg <= count_reg + 1; end endmodule

2. Verilog Simulation

Ask Claude: "Please simulate this adder with a testbench" // Design module adder( input [3:0] a, input [3:0] b, output [4:0] sum ); assign sum = a + b; endmodule // Testbench will be generated automatically or you can provide one

3. ASIC Design Flow

Ask Claude: "Run the complete ASIC flow for this design with a 10ns clock period" module simple_cpu( input clk, input rst, input [7:0] data_in, output [7:0] data_out ); // Your RTL design here endmodule

What you get after completion:

  • runs/RUN_*/final/gds/design.gds - Final GDSII layout

  • runs/RUN_*/openlane.log - Complete execution log

  • runs/RUN_*/reports/ - Timing, area, power analysis reports

  • All intermediate results (DEF files, netlists, etc.)

4. Waveform Analysis

Ask Claude: "View the waveforms from the simulation with project ID: abc123"

Troubleshooting

Common Issues

  1. MCP Server Not Detected:

    • Verify the absolute path in configuration

    • Check that Node.js is installed and accessible

    • Verify tools are installed: yosys --version, iverilog -V, gtkwave --version

    • Check PATH environment variable in MCP configuration

    • On macOS, ensure Homebrew paths are included: /opt/homebrew/bin

  4. OpenLane Timeout:

    • The server has a 10-minute timeout for OpenLane flows

    • For complex designs, consider simplifying or running multiple iterations

  5. GTKWave/KLayout GUI Issues:

    • On macOS: GTKWave/KLayout may need manual approval in Security & Privacy settings

    • On Linux: Ensure X11 forwarding is working if using remote systems

    • On Windows: Ensure GUI applications can launch from command line

Debugging

  1. Check MCP Server Logs:

    • Claude Desktop: ~/Library/Logs/Claude/mcp*.log (macOS)

    • Cursor: Check the MCP settings panel for error messages

  2. Test Tools Manually:

    yosys -help iverilog -help docker run hello-world gtkwave --version klayout -v

  3. Verify Node.js Environment:

    node --version npm --version
