fix: increase timeouts for long text input

[OrKoN]

Fixes #786

[kth8]

@OrKoN thanks for the quick fix. I tried your patch but still getting timed out, after 10 seconds this time instead of 5.

This is what my agent came up with to increase timeout to 60 seconds:

I think fill_form also have this behaviour.

@kth8 I think the agent is not quite right here because the locator.fill() ends up in keyboard.type:

• https://github.com/puppeteer/puppeteer/blob/main/packages/puppeteer-core/src/api/locators/locators.ts#L499
• https://github.com/puppeteer/puppeteer/blob/main/packages/puppeteer-core/src/api/ElementHandle.ts#L1136

We also do not want a 60 sec timeout as it is too long if there are other issues not related to typing. Perhaps we should just have a different tool like paste_text for large blocks of texts so it does not require typing.

Are you sure you correctly re-built and used the server from this branch? can you reproduce the timeout by running the tests from this PR on your machine? can you try adding a test that would demonstrate the timeout? I wonder if there is some dependency on the page content?

I think your suggest of adding a separate paste_text tool is a good option.

I cloned the branch with your patch and ran it via

git clone -b orkon/input-timeout https://github.com/ChromeDevTools/chrome-devtools-mcp.git
npm ci
npm run build
node build/src/index.js --browserUrl=http://192.168.122.239:9223

I tried on another site like chatgpt.com and the tool didn't timeout like before but MCP itself did this time, but I think that may be a client (opencode) configuration issue. A paste_text would prevent this and save a lot of time.

Thanks for testing! I think we will land this next week (maybe increasing timeouts linearly according to the input length, instead of per block of 1k chars). But I think I will also look into fixing the fill() method in Puppeteer to switch to pasting the entire text at once for large texts.
