External MCP tool discovery now spawns
pcb-*backends usingmcp --code-mode falseto avoid nested code-mode wrappers, falling back to plainmcpwhen the flag isn’t supported.ExternalMcpServer::spawnwas refactored to try multiple MCP CLI argument sets via a newspawn_with_mcp_argshelper, and the change is documented inCHANGELOG.md.Written by Cursor Bugbot for commit a4c7a34.
