What

The claude mcp add command now supports -- to separate the command from its arguments.

Usage
claude mcp add myserver -- node server.js --port 3000
Details
  • Allows cleaner separation when MCP server commands have their own arguments
  • Arguments after -- are passed directly to the server command
Evidence

ZC9() at line 535512 (contains "--" && Q.length > 0)

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
