PC Build Advisor MCP

PC Build Advisor MCP

M8ven Live Monitored

An interactive PC compatibility checker that works as an MCP App inside ChatGPT and as a regular browser application.

It checks supplied component specifications for CPU socket, memory generation, motherboard and case fit, GPU and cooler clearance, RAM and storage slots, GPU power connectors, and PSU capacity.

MCP tools

Tool

What it does

open_pc_build_advisor

Opens the interactive compatibility checker.

check_pc_compatibility

Checks a complete build and returns structured conflicts and fixes.

estimate_power_supply

Estimates system load and a recommended PSU capacity.

The tools remain useful without the visual component. Results depend on the specifications supplied by the user and should be confirmed against manufacturer documentation before buying hardware.

Run locally

Requirements: Node.js 20 or newer.

npm install
npm run build
npm start

Open http://localhost:8787 for browser mode. The Streamable HTTP MCP endpoint is:

http://localhost:8787/mcp

Test

npm test
npm run build
npm run smoke

Use MCP Inspector for direct protocol testing:

npx @modelcontextprotocol/inspector@latest

Choose Streamable HTTP and connect to http://localhost:8787/mcp.

Deploy

The included render.yaml and Dockerfile define a Render web service with a /health check. After deployment, connect ChatGPT to the public HTTPS URL ending in /mcp.
