+## Configuration
+
+You can configure Oh My OpenCode by creating a `oh-my-opencode.json` (or `.oh-my-opencode.json`) file in your project root.
+
+### Disable specific MCPs
+
+If you want to disable specific built-in MCPs, you can use the `disabled_mcps` option.
+
+```json
+{
+  "disabled_mcps": ["context7", "websearch_exa"]
