feat(browser): update chrome-devtools-mcp

[kunal-10-cloud]

Summary

Update chrome-devtools-mcp to version 0.18.1 and replace the custom type_text tool implementation with the native version now provided by the MCP server.

Details

• Upgraded MCP server version to 0.18.1.
• Removed custom type_text implementation and related declarative tool classes.
• Refactored tool creation to use dynamic discovery for type_text.
• Updated unit tests to align with native tool discovery.

Related Issues

Closes #20983

How to Validate

1. Run browser agent unit tests: npm test -w @google/gemini-cli-core -- src/agents/browser
2. Verify type_text is correctly discovered from the MCP server.

Summary of Changes

Hello, 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 significantly refines the browser agent's interaction with browser automation by upgrading the chrome-devtools-mcp dependency. This upgrade allows the system to leverage the newly available native type_text tool directly from the MCP server, eliminating the need for a previously custom-built implementation. The change streamlines the tool integration process, reduces internal code complexity, and ensures the agent benefits from the latest features and optimizations provided by the underlying browser control mechanism.

Highlights

• Dependency Update: The chrome-devtools-mcp dependency has been updated to version 0.18.1.
• Native type_text Tool Adoption: The custom implementation of the type_text tool has been removed and replaced with the native version now provided by the updated chrome-devtools-mcp server.
• Code Simplification: The TypeTextInvocation and TypeTextDeclarativeTool classes, which housed the custom type_text logic, have been removed, simplifying the codebase.
• Dynamic Tool Discovery: Tool creation has been refactored to dynamically discover type_text from the MCP server, aligning with how other native tools are handled.
• Unit Test Alignment: Unit tests have been updated to reflect the change in type_text discovery and adjusted expected tool counts.

Changelog

• packages/core/src/agents/browser/browserAgentFactory.test.ts
  • Added 'type_text' to the mock list of browser manager tools.
  • Adjusted expected tool counts in tests to account for 'type_text' being a standard MCP tool.
• packages/core/src/agents/browser/browserManager.ts
  • Updated the CHROME_DEVTOOLS_MCP_VERSION constant from 0.17.1 to 0.18.1.
• packages/core/src/agents/browser/mcpToolWrapper.test.ts
  • Modified assertions to expect 2 tools instead of 3, reflecting the removal of the custom 'type_text' tool from the dynamically discovered list.
• packages/core/src/agents/browser/mcpToolWrapper.ts
  • Removed the TypeTextInvocation class, which implemented the custom 'type_text' logic.
  • Removed the TypeTextDeclarativeTool class, which wrapped the custom 'type_text' tool for declarative use.
  • Updated the createMcpDeclarativeTools function to no longer explicitly add the custom 'type_text' tool, relying solely on dynamically discovered MCP tools.

Code Review

This pull request correctly updates the chrome-devtools-mcp dependency to version 0.18.1 and refactors the browser agent to use the native type_text tool provided by the updated MCP server. The removal of the custom TypeTextInvocation and TypeTextDeclarativeTool classes simplifies the codebase and likely improves performance. The associated test files have been updated appropriately to reflect these changes. The implementation is clean and aligns with the stated goals.

There was a regression fixed in #21766 due to which I couldn't test this earlier. Will review again.

Can you update this test to include type_text packages/core/src/agents/browser/browserAgentFactory.test.ts?
