## Summary
This PR enhances the `list_network_requests` tool with pagination
support to handle large numbers of network requests efficiently. See
[this
issue](https://github.com/ChromeDevTools/chrome-devtools-mcp/issues/136).
## Motivation
In my experience, the `list_network_requests` tool frequently hits LLM
token limits on pages with many requests, making it unusable for modern
web applications. I wanted to add pagination to allow agents to be more
flexible and manage token limits on their own.
## Changes
### Pagination Support
- Added `pageSize` parameter to limit requests per call
- Added `pageToken` parameter for navigation between pages
- Added pagination metadata in responses (nextPageToken,
previousPageToken, startIndex, endIndex, total)
### Implementation Details
- **New utility**: `src/utils/pagination.ts` - generic pagination
function
- **Enhanced McpResponse**: Added pagination options to
`setIncludeNetworkRequests()`
- **Updated network tool**: Added pagination parameters to schema
- **Offset-based pagination**: Uses numeric tokens, handles invalid
tokens gracefully
## Testing
- Comprehensive test coverage for pagination scenarios
- Tests for first page, subsequent pages, invalid tokens, and edge cases
- All existing tests continue to pass
## Backward Compatibility
- If no pagination parameters are provided, the MCP will return all
requests (same as before)
McpContext currently assumes that there is a page. Eventually we might
support closing the browser by closing the last page but right now we do
not really have responses that indicate that the browser was closed. So
this PR helps the LLM understand that it is okay to keep the last page
running (and there are platform-specific differences as to what happens
if the last page is closed).
