CCA-F: Claude Certified Architect — Foundations

Claude Code's project scope stores MCP server definitions in a .mcp.json file that is intended to be checked into version control and shared with the entire team, making it the correct location for a server everyone should be able to use, such as the shared venue lookup server. In contrast, local/user-scoped servers are stored in the individual's ~/.claude.json file and remain private to that user across their own projects, which is the appropriate place for a personal, experimental server like the music playlist server that only one person is testing and that should not be pushed to teammates via the shared project configuration.
