The openclaw client name is defined at
https://github.com/openclaw/openclaw/blob/ea476de1e488979a3e9e5bf32e4d4f20e563144f/src/browser/chrome-mcp.ts#L234C14-L234C29

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.

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.

methods and moved whatever is relevant to the McpPage. Also, duplicate
getters would go away.

feat: add pageId routing for parallel multi-agent workflows ( #1022 )
...
## Summary
Adds optional `pageId` routing to page-scoped tools, gated behind
`--experimental-page-id-routing`. When enabled, multi-agent callers can
target a specific page without relying on global selection state. Fully
backward-compatible: without the flag, behavior is unchanged.
### Key changes
- **`pageScoped` annotation**: tools declare `pageScoped: true`; the
server merges `pageId` into their schema at registration time (when the
flag is on)
- **`McpPage` wrapper**: consolidates per-page state (numeric id,
isolated context name, focus tracking) into a single class
- **Request-scoped page routing**: `resolvePageById()` resolves the
target page, `setRequestPage()` threads it through the handler so tools
like `getSelectedPage()` see the right page
- **`assertPageIsFocused`**: keyboard/input tools validate that the
target page holds browser focus, returning an actionable error ("call
select_page first") instead of silently dispatching to the wrong page
- **`--experimental-page-id-routing` CLI flag** (hidden): gates schema
injection and request-scoped routing so the feature can be tested before
graduating
- **Eval scenarios**: `page_id_routing_test` and
`page_focus_keyboard_test` with `serverArgs` support in the eval harness

chore: implement a daemon process ( #1020 )
...
Implements a daemon process needed for the CLI. The daemon has commands
to start/stop itself as well as an ability to forward data to the
managed MCP server. Local sockets or named pipes are used depending on
the platform.
The .sock and .pid files are placed under
XDG_RUNTIME_DIR/chrome-devtools-mcp or /tmp/chrome-devtools-mcp for
short socket paths.
It uses Puppeteer's PipeTransport to avoid re-implementing \0 terminated
messages.
Note the code is not used anywhere at the moment.
