The JLCPCB/LCSC parts library, inside your AI assistant

Next Everything puts the 630,000+ in-stock parts of the JLCPCB/LCSC library, refreshed daily, behind an MCP server. Your assistant can search it by specs, check your whole BOM against it and tell you what assembly at JLCPCB will cost, without you clicking through the parts library.

Built for JLCPCB assembly

  • Basic vs extended parts. Run check_bom with assembly: true and the $3 fee per extended part counts in the price, with no-fee basic or preferred alternatives suggested.
  • Search only basic parts with no_assembly_fee in find_parts and find_alternatives.
  • LCSC numbers everywhere. An LCSC Part column in your BOM pins the exact part, and any C-number such as C2557 works in a search.
  • Footprint availability and pinouts for each part.

Search by electrical specs

find_parts filters by category, package, manufacturer and specs such as rds_on <= 10mΩ or a supply voltage range, sorted by match, price or stock. Your assistant sees every spec key in the tool definition, so you can just describe what you need.

Compared with DigiKey and Mouser

For every part in your BOM we also check DigiKey and Mouser live, so you see when a part is cheaper or better stocked elsewhere, and when JLCPCB stock is too low for your build.

Try asking

  • “Check this KiCad BOM for JLCPCB assembly of 20 boards and replace extended parts with basic ones where possible.”
  • “Find a basic-part 10k 0402 resistor and a 100nF 0402 capacitor at JLCPCB.”
  • “Find an N-channel MOSFET in SOT-23 with Rds(on) under 30 mΩ at 4.5 V, in stock at LCSC.”
