Description
Description of the bug
When prompting an AI agent to “check LCP” or investigate slow page loads, the agent does not automatically invoke the relevant DevTools MCP performance tools. Tool usage only occurs when explicitly instructed. This seems like a tool discoverability/description issue, and improving tool metadata or prompt-to-tool mapping could make performance debugging more natural.
Reproduction
Chrome DevTools MCP server
AI assistant Cursor IDE invoking MCP tools

Research direction
Start by reproducing the behavior with the Chrome DevTools MCP server and Cursor IDE using prompts about LCP and slow page loads. Inspect the performance tool metadata and prompt-to-tool mapping described in the issue. Done means relevant performance tools are invoked from natural performance-debugging prompts without explicit tool instructions.
