THEN Pass the input schema as a plain object literal, not `z.object()`. Replace `z.object({ query: z.string() })` with `{ query: z.string() }` in the `server.tool()` call.

// Incorrect (causes error):
server.tool("search", z.object({ query: z.string() }), handler);

// Correct:
server.tool("search", { query: z.string() }, handler);
