 ## CONFIG PATTERN
 
-All MCPs follow identical structure:
 ```typescript
 export const mcp_name = {
   type: "remote" as const,
   url: "https://...",
   enabled: true,
-  oauth: false as const,  // Explicit disable
-  headers?: { ... },      // Optional auth

 ## HOW TO ADD
 
-1. Create `src/mcp/my-mcp.ts`:
-   ```typescript
-   export const my_mcp = {
-     type: "remote" as const,
-     url: "https://mcp.example.com",
-     enabled: true,
-     oauth: false as const,
-   }
-   ```
+1. Create `src/mcp/my-mcp.ts`
 2. Add to `allBuiltinMcps` in `index.ts`
 3. Add to `McpNameSchema` in `types.ts`
 
 ## NOTES
 
-- **Remote only**: All built-in MCPs use HTTP/SSE, no stdio
-- **Disable config**: User can disable via `disabled_mcps: ["name"]`
-- **Exa requires key**: Set `EXA_API_KEY` env var for websearch
+- **Remote only**: HTTP/SSE, no stdio
+- **Disable**: User can set `disabled_mcps: ["name"]`
+- **Exa**: Requires `EXA_API_KEY` env var
