modify_component
Change a component value in a stored circuit
How to use it
modify_component is exposed by the Spicebridge MCP server. Add the server to your MCP client (Claude Desktop, Cursor, Windsurf and others), and the modify_component tool becomes available to the model automatically. See the full listing for setup details and every tool this server provides.
