Claude Code Settings MCP And Channels

Claude Code Settings: MCP and Channels

These keys decide which MCP servers and channels Claude Code may use. Administrators use them to allow or block servers. For example, { "enableAllProjectMcpServers": true } approves every server in a project .mcp.json file.

The marks and the scopes are explained on Settings. A - in the Default column means that neither the docs nor the schema state a default.
