- reduces the token usage.
- makes emulation and script compatible with CLI.
- documents .nullable() and .object() restrictions for the future.
- the emulation tools do not have nullable anymore and undefined would
clear the emulation instead. The model is thus required to provide all
emulation settings at once.
Closes https://github.com/ChromeDevTools/chrome-devtools-mcp/issues/918
- renamed getSelectedPage to getSelectedPptrPage
- removes getSelectedPptrPage from tool interfaces
- moves dialog handling to McpPage
- makes responses to be optionally McpPage-scoped
I split this PR off from my "create one DevTools universe per page" PR
in preparation. This allows tests to re-use browser instances without
creating an `McpContext`.
Drive-by: Move mocked browser/page into utils.ts.
This PR prevents license notices being dropped when creating package for
publication.
This can happen when first import in the file is type-only import that
gets removed during build. When there is no empty line between the
license block comment and such import, the comment is treated as related
to the import and gets removed alongside it.
Adding an empty line between copyright notice and the import fixes the
issue.

Issue:
It would be very useful to have the ability to simulate offline network
conditions directly through the MCP emulate_network command, similar to
how it's possible in DevTools.
Currently, the command doesn’t support an Offline state, which limits
testing for PWA and offline-first web applications. Adding this option
would make it easier to automate and validate offline behavior through
MCP scripts or tools that rely on this API.
Solution
- Add 'Offline' option to throttlingOptions for simulating offline
network conditions
- Update emulate_network tool to handle offline mode with proper network
conditions
- Update documentation to include offline option and usage instructions
- Add test coverage for offline network emulation functionality
- Enable testing of PWA and offline-first web applications through MCP
