feat: include page title in list_pages output ( #2166 )
...
## Motivation
`list_pages` shows each page's URL but not its title, which is painful
when multiple pages share a host — e.g. several tabs under
`app.example.com/u/0/`, `/u/1/`, `/u/2/`. There's no way to tell which
is which without visiting each one, even though every page has a usable
`document.title`.
Fixes #2156 .
Closes #2175
## What this changes
- `list_pages` text output now shows the title before the URL when
available: `1: My Page (https://example.com ) [selected]`. If the page
has no title (e.g. `about:blank`), the format is unchanged.
- The structured content entry for each page now includes a `title`
field alongside `id`, `url`, and `selected`.
- `page.title()` is awaited with a `.catch(() => '')` so a closed or
erroring page silently falls back to the URL-only format.
- `format()` is made `async` to support the `await` inside the page
loop; `createStructuredPage()` likewise becomes `async`.
## Testing
Start the MCP server with multiple tabs open. Call `list_pages` — pages
with titles now display as `id: Title (url)`. Pages without titles
(`about:blank`, data URLs) display as before.

feat: Handle multiple providers of third-party developer tools ( #2168 )
...
This allows a page to have multiple providers of third-party developer
tools, which each respond to the `devtoolstooldiscovery` event.
- Multiple `ToolGroup`s
- MCP tool responses only mention third-party developer tools, if there
are any. Otherwise this part of the output is skipped.

feat: support third-party developer tools ( #1982 )
...
Enables "third-party developer tools" feature. This allows the inspected
web page to expose tools which provide debugging information to Chrome
DevTools for Agents.
Third-party developer tools enable web applications to expose internal
state, component hierarchies, or specific debug data that cannot be
deduced through static analysis. This allows Chrome DevTools for Agents
to provide richer, more actionable context to AI agents during debugging
sessions.
2 additional tools are enabled in Chrome DevTools for Agents for
interacting with third-party developer tools:
`list_3p_developer_tools()` and `execute_3p_developer_tool`.
Code changes in this PR:
- Rename "in-page tools" to "third-party developer tools"
- Unhide
- Make available in CLI
- Add documentation

feat: support DevTools header redactions as an option ( #1848 )

This PR adds a CLI flag to enable redacting network headers in the same
way they are redacted in DevTools. Note that sometimes it might prevent
the agent from properly analysing network issues. Pass
`--redact-headers=false` to revert to the previous behavior.

feat: Add a new tool for listing in-page tools (gated behind a command line flag) ( #1239 )
...
This adds a `list_in_page_tools` MCP tool. When called, it dispatches a
`devtoolstooldiscovery` event on the active page. The page announces its
exposing tools by calling the event's `respondWith` method, which causes
the exposed tools to be stashed on the page's `window` object. This list
of in-page tools is then appended to the `list_in_page_tools` response.
Calling the exposed in-page tools from the MCP server will be handled in
a follow-up.
