Have Claude design a VGA logic board and fab it at JLCPCB for $6
Claude Opus 4.8 designed a 74-series logic and GAL circuit that outputs an EEPROM image over VGA. The owner routed it, JLC made it for $6, and it worked after one bodge wire.
Do this with your agent
How you could do the same thing today. “Official MCP” is the vendor's own server. “Manual” means you use the provider's own site or app.
- JLCPCBAPI from the vendor
Named in this story. Order manufactured printed circuit boards from Gerber files. It is in our catalog: our connector finds it and returns the provider's link. It does not place the order.
- Real World MCPFind it through our connector
Add our server and ask your agent to run search_tools. It lists PCBWay and SendCutSend with prices and links. It does not place orders.
- Order PCBs from ClaudeStep by step
What works today, through which server, at what price.
Every MCP server and API we list for this kind of job, with install lines, auth and price.
