JLCPCB Skills

AI-agent skills and scripts for searching the JLCPCB / LCSC parts catalogue.

Use cases

Search parts

Point your coding agent at a BOM (KiCad, CSV, schematic netlist, etc.) and ask it to resolve every line to a part that is currently in stock at JLCPCB — preferring Basic parts to avoid extended-part fees, matching package, value, tolerance, voltage, and other parametric constraints.

Example prompt:

Fill the BOM with parts available from JLCPCB.
Prefer Basic parts. For each line, output MPN, LCSC number, stock, and Basic/Extended.

Find 0.1uF 0603 X7R 25V+ Basic capacitor on JLCPCB.

Update local catalogue

Ask your coding agent to update the local SQLite catalogue from the upstream JSON shards.

Update the local JLCPCB parts catalogue.

Install

In Claude Code:

/plugin marketplace add mash/jlcpcb-skills
/plugin install jlcpcb-skills@jlcpcb-skills

Available next session. The skill installs the jlcpcb-parts CLI itself on first use, picking the method (pipx / uv / venv pip / …) that fits your Python environment. To skip bootstrap, install git+https://github.com/mash/jlcpcb-skills.git yourself however you like.

Data source

The local SQLite is built from the JSON shards published by yaqwsx/jlcparts at https://yaqwsx.github.io/jlcparts/data/ (refreshed every ~6h upstream). yaqwsx/jlcparts is licensed under the MIT License (Copyright (c) 2024 Jan Mrázek).

This repository does not redistribute the catalogue data — each user fetches it directly from the upstream CDN on first use of the update command.
