Instead of making MCP tool calls, LLMs write TypeScript against auto-generated RPC clients. // Follow the readme instructions and run the RPC server

  mcp-rpc-runtime -r ./test-rpc -p 8080

Drop .ts files with typed exports: // ./test-rpc/users.ts export async function getUser(args: { id: number }): Promise<User> { ... }

The system generates a typed client. LLMs write normal TypeScript: const [user, orders] = await Promise.all([ rpc.users.getUser({ id: 123 }), rpc.orders.getHistory({ userId: 123 }) ]);

No MCP servers needed. The RPC runtime has full system access, while LLM scripts run sandboxed with only network permissions.
