jlc_find_alternatives

MCP tool from Pcbparts MCP by Averyy

Find spec-compatible alternative parts with verification

How to use it

Project documentation lists jlc_find_alternatives for the Pcbparts MCP MCP server. Add the server to your MCP client (Claude Desktop, Cursor, Windsurf and others), then check which tools your installed version makes available. Tool availability can depend on configuration and credentials. A server handshake does not verify this tool’s behavior. See the full listing for setup details.
