DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.
When using MCP-related commands, the scope names have changed:
# Adding an MCP server with the new scope names
claude mcp add --scope local # Adds to current project only
claude mcp add --scope user # Adds to all your projects
# The allowed scopes list now shows:
# ["local", "user"] instead of ["user", "global"]
