Description:
When importing from @modelcontextprotocol/sdk/types.js, a module resolution error occurs indicating that the import path cannot be resolved.

Error Message:

TypeError: Failed to resolve module specifier "@modelcontextprotocol/sdk/types.js". 
Relative references must start with either "/", "./", or "../".

Stack Trace:

Uncaught TypeError TypeError: Failed to resolve module specifier "@modelcontextprotocol/sdk/types.js". Relative references must start with either "/", "./", or "../".

Environment:

• VS Code Version: 1.99.0
• @modelcontextprotocol/sdk Version: 1.7.0
• Node.js type: "module" (ESM)

Issue Description:
The error occurs when trying to import the types.js module from @modelcontextprotocol/sdk package. This appears to be an ESM module resolution issue where the import path needs to use relative path syntax.

Steps to Reproduce:

1. Set "type": "module" in package.json
2. Install @modelcontextprotocol/sdk@1.7.0
3. Try to import from "@modelcontextprotocol/sdk/types.js"
