An MCP server for JLCPCB PCBA to assist in component searching

Overview

Additionally, the following page covers the selection of resistance values for buck-type DC-DC converters. https://claude.ai/share/9f02f1a4-7b38-48fb-b29a-f10cf1e608ba As the database, I use the JLC PCB SMD Assembly Component Catalogue. Here, you need cache.sqlite3, which is provided as a split ZIP. As of April 2025, the number up to cache.z19 exists. Create an environment where MCP is available in Python and specify server.py as the server. Also, you need to set the path to the database to the JLCPCB_DB_PATH environment variable.
