feat: record client name in telemetry. ( #1208 )
...
The changes in the PR intercepts the name of the MCP client right after
server initialization, coverts it into one of the existing enum values,
and append it with the telemetry request.
Note that the client name is unset if there is no client connected yet.
This means the server_start event won't have a client name.
Tested with gemini-cli.

perf: use CDP to find open DevTools pages (reland) ( #1210 )

This should reduce the flakiness and issue with finding open DevTools
tabs for the corresponding pages.
Currently we do multiple loops over all the targets, so this should have
a nice performance improvement when multiple pages are opened.
With a fallback for older versions.

perf(memory): release old navigation request in NetworkCollector ( #1200 )
...
Issue #1192
## Problem
In `--autoConnect` mode, `chrome-devtools-mcp` experiences a severe
memory leak (~13 MB/min) when Chrome is actively used. This eventually
leads to OOM crashes or kernel panics.
The root cause is in `src/PageCollector.ts`:
1. `NetworkCollector` overrides `splitAfterNavigation` but forgets to
call `navigations.splice(this.#maxNavigationSaved)`, causing the array
of navigations to grow infinitely.
2. Even within a single navigation (e.g., in long-lived SPA
applications), the `navigations[0]` array grows infinitely because there
is no limit on the number of items collected per navigation. Since
`HTTPRequest` objects are heavy, this quickly exhausts memory.
## Solution
1. Changed `#maxNavigationSaved` to `protected maxNavigationSaved` so
subclasses can access it.
2. Added `navigations.splice(this.maxNavigationSaved)` to
`NetworkCollector.splitAfterNavigation` to ensure old navigations are
properly discarded.
3. Introduced `protected maxItemsPerNavigation = 5000` to limit the
number of items stored per navigation. When the limit is reached, the
oldest item is removed (`shift()`), preventing unbounded memory growth
in SPAs.
Tested locally by running `npm run build` and verifying the fix.

chore: implement chrome-devtools CLI ( #1079 )
...
Note that the implementation for response handling and daemon start/stop
is still a placeholder. The proper handling will be done in follow-ups.
The `generateCustomHelp` function is also fully experimental and it is
likely to get removed before the release. The goal of this PR is to
scaffold the e2e workflow for early manual testing. Automated tests will
be also added in a follow-up.
Note this does not expose the CLI as a binary on the package.

chore: implement trigger extension action ( #1049 )
...
This PR implements the ability to trigger an extension action by passing
it an extension id.
It uses puppeteer internals and the canary chrome version in tests since
the TriggerAction CDP command is still not available in the current
stable release.

e51ba47203
fix: simplify emulation and script tools ( #1073 )
...
- 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

Follow-up to
https://github.com/ChromeDevTools/chrome-devtools-mcp/commit/caf601a32832bb87cfac801a6bbeacb87508412f
The work is not complete and as a follow-up I will handle other Context
methods and moved whatever is relevant to the McpPage. Also, duplicate
getters would go away.

chore: implement daemon client ( #1037 )
...
The client is meant to start the daemon if it is not running or connect
to the existing one. Long-running client connections are not needed yet.
Removed previous direct daemon test as we better test it via the client,
the intended way to manage the daemon.
