PCB Parts MCP Server

Find alternative parts similar to a given component.

Searches the same subcategory for parts with better availability. Useful when a part has low stock or you want to compare options.

Args: lcsc: LCSC part code to find alternatives for (e.g., "C2557") min_stock: Minimum stock for alternatives (default: 10) same_package: If True, only return parts with the same package size library_type: Filter alternatives by library type: - "basic": Only basic parts (no assembly fee) - "preferred": Only preferred parts (no assembly fee) - "no_fee": Basic or preferred (no assembly fee) - best for cost optimization - "extended": Only extended parts ($3 assembly fee each) - "all" or None (default): All library types Use "no_fee" to find cheaper alternatives for an extended part. has_easyeda_footprint: Filter by EasyEDA footprint availability: - True: Only return parts WITH EasyEDA footprints (for Atopile/KiCad users) - False: Only return parts WITHOUT footprints - None (default): Don't filter by footprint (fastest) Note: Filtering by footprint is slower as it checks each alternative. limit: Maximum alternatives to return (default: 10, max: 50)

Returns: Original part info (with library_type and has_easyeda_footprint) and list of alternatives sorted by stock. Alternatives include library_type and specs for easy comparison. When filtering by footprint, alternatives also include EasyEDA UUIDs.
