When does this happen?

IF Importing @modelcontextprotocol/sdk causes TypeScript compilation to process 430+ files due to complex type definitions, resulting in out-of-memory errors even with 4GB+ heap limits.

How others solved it

THEN Use tsc with the --noCheck flag to bypass type checking during the build step, then run type checking separately (e.g., as a lint step). Alternatively, upgrade to SDK v2 which removes zod-derived types, or try the Go-based TypeScript compiler (tsgo) for reduced memory usage.

  "scripts": {
    "build": "tsc -p tsconfig.build.json --noCheck"
  }
}
