Mcp-Server

The server relies on client-provided `userId`, `agentId`, and `todoListId` in query parameters for establishing session context, which are then used directly in database queries for data filtering and ownership (`eq(block.userId, userId)`). There is no explicit in-code validation or authentication of these IDs against a trusted source (like an `mcp_access_tokens` table) during session establishment shown in `main.ts`. This means an unauthenticated client could potentially impersonate any user or access/modify unauthorized data by supplying arbitrary IDs if the server is exposed publicly without a robust authentication layer in front. Additionally, CORS is configured with `origin: '*'`, allowing requests from any domain, which is broad for a publicly exposed API. Hardcoded secrets are avoided by using environment variables. Database operations use Drizzle ORM, which helps prevent SQL injection.
