Once configured, PCB Parts MCP Server gives your AI agent access to:

jlc_searchPrimary search with smart query parsing and parametric spec filters for JLCPCB parts.

jlc_stock_checkReal-time stock verification via live JLCPCB API.

jlc_get_partFull details for a specific LCSC part code or MPN lookup.

jlc_get_pinoutComponent pin information from EasyEDA symbols.

jlc_find_alternativesFind spec-compatible alternative parts with verification.

jlc_search_helpBrowse categories, subcategories, and filterable attributes.

mouser_get_partCross-reference a specific MPN on Mouser.

digikey_get_partCross-reference a specific MPN on DigiKey.

sensor_recommendFind sensor ICs/modules by measurement need, protocol, or platform.

get_design_rulesAccess PCB design rules and best practices reference files.

cse_searchSearch for ECAD models, datasheets, and footprint availability.

cse_get_kicadDownload KiCad symbols and footprints for any part.

After setup, try these prompts with your AI agent:

→Find a 10k ohm 0603 resistor with 1% tolerance on JLCPCB.

→Search for a MOSFET with Vgs(th) < 2V and Rds(on) < 10mΩ.

→Find alternatives for the part number LM358.

→Download the KiCad footprint for the part with MPN C12345.

→Recommend a temperature sensor that uses I2C protocol.
