[REQUEST] codegen for MCP? #42338
Description
What's going on?
Could we support codegen in MCP ? Or, better yet, can we allow attaching to the browser extension from the existing npx playwright codegen?

Hi, I'm the Playwright bot and I took a first look at this.
Both of these are already possible today with the Playwright MCP server (
npx playwright run-mcp-server/@playwright/mcp) — it's not the classicnpx playwright codegenrecorder, but it covers the two things you're asking for.--codegen <typescript|python|java|csharp|none>. On top of that, the@playwright/testMCP backend has a dedicated test-generation flow —generator_setup_page→generator_read_log→generator_write_test— that records what happened and writes a real spec file.--extension(needs the "Playwright Extension" installed). So you get the "attach to my real browser and generate code" workflow, just from the MCP side rather than thecodegenCLI.Where this lives in the source
--codegenoption and the "Ran Playwright code" rendering:packages/playwright-core/src/tools/backend/codegen.tsandresponse.ts(config fieldcodegen?: 'typescript' | 'python' | 'java' | 'csharp' | 'none').packages/playwright/src/mcp/test/generatorTools.ts.--extension(attach to a running Edge/Chrome via the Playwright Extension):packages/playwright-core/src/tools/mcp/program.ts.So the "codegen for MCP" ask is largely covered. The one genuinely new thing here would be teaching the standalone
npx playwright codegenrecorder to attach to the extension the same way MCP does — worth clarifying whether that specific UI is what you're after, or whether the MCP--codegen/ generator flow already gets you what you need.Triaged by the Playwright bot - agent run

I want Playwright to attach to my existing Chrome tab, record what I do, wait for me to tell it I'm finished, and then generate a sequence of playwright commands reflecting my actions.
