+### Default MCP Servers Configuration
+
+You can configure default MCP servers that sessions will automatically connect to:
+
+```bash
+# List default MCP servers
+mc config mcp list
+
+# Add an MCP server to defaults
+mc config mcp add github
+
+# Remove an MCP server from defaults
+mc config mcp remove github
+```
+
+When adding new MCP servers, they are added to defaults by default. Use the `--no-default` flag to prevent this:
+
+```bash
+# Add an MCP server without adding it to defaults
+mc mcp add github ghcr.io/mcp/github:latest --no-default
+mc mcp add-remote jira https://jira-mcp.example.com/sse --no-default
+```
+
+When creating sessions, if no MCP server is specified with `--mcp`, the default MCP servers will be used automatically.
