fix(ide): use CLI version in MCP client handshake (#3487)

[Aman071106]

Summary

Replaces the hardcoded version: '1.0.0' in both MCP client initializations (StreamableHTTPClientTransport and StdioClientTransport) with a call to getVersion() from utils/version.ts, so the IDE receives the actual CLI version during the MCP protocol handshake.

Details

The Client constructor in ide-client.ts was using a hardcoded '1.0.0' string in two places (lines 591 and 626). The existing getVersion() utility already resolves the CLI version from CLI_VERSION env var or package.json, so this change simply imports and uses it. Both call sites are in async functions, so await getVersion() works directly.

How to Validate

1. Run the IDE client tests:

   npm test -w @google/gemini-cli-core -- src/ide/ide-client.test.ts

   All 26 tests should pass.

2. Verify the import and usage:

   grep -n "getVersion" packages/core/src/ide/ide-client.ts

   Should show the import on line 25 and usage on lines 590 and 624.

3. Run full preflight:

   npm run preflight

Summary of Changes

Hello @Aman071106, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request addresses an issue where the IDE client was reporting a static version during its handshake with the server. By integrating a utility function to dynamically retrieve the CLI's actual version, the change ensures that the client-server communication is based on accurate version information, which is crucial for compatibility and debugging.

Highlights

• Dynamic CLI Versioning: Replaced the hardcoded '1.0.0' version string in MCP client initializations with a dynamic call to getVersion() from utils/version.ts.
• Accurate Handshake: Ensured that the IDE now receives the actual CLI version during the Model Context Protocol (MCP) handshake, improving client-server communication accuracy.

Changelog

• packages/core/src/ide/ide-client.ts
  • Imported the getVersion utility function.
  • Updated StreamableHTTPClientTransport client initialization to use await getVersion().
  • Updated StdioClientTransport client initialization to use await getVersion().

Activity

• The author provided detailed validation steps, including running IDE client tests, verifying import and usage with grep, and performing a full preflight check.
• The author completed a pre-merge checklist, confirming documentation updates and validation on Windows.
