Chrome DevTools for agents

Chrome DevTools is a set of web authoring, debugging, and performance analysis tools built into Google Chrome and other Chromium-based browsers. Maintained by the Chromium/Chrome team at Google, it provides DOM inspection, JavaScript debugging, network monitoring, and performance profiling for web developers.

Page Agent is a JavaScript in-page GUI agent that lets users control web interfaces with natural-language instructions. It operates through text-based DOM manipulation inside the webpage, without requiring a browser extension, Python, screenshots, multimodal models, or a headless browser. It can be integrated with a script tag or installed from NPM, and supports bring-your-own LLM configurations, including locally deployed models. An optional Chrome extension supports multi-page tasks, while a beta MCP server allows external agent clients to control the browser. The project is distributed under the MIT License and is designed for client-side web enhancement rather than server-side automation.

Context Mode is an MCP server and plugin for AI coding agents that reduces context-window usage by routing large tool outputs through sandboxed subprocesses. Its execution tools run code in supported languages, process files, fetch and analyze URLs, and return selected stdout or search results instead of exposing raw logs, snapshots, API responses, or file contents to the conversation. The project reports up to 98% context reduction in its benchmarks. It also provides session continuity across supported agents. Hooks capture tool calls, edits, prompts, decisions, errors, and other session events in SQLite; before compaction, the system builds a prioritized resume snapshot, and after compaction or session resumption it retrieves relevant events through SQLite FTS5 search with BM25 ranking. Content indexing uses heading-aware chunking, stemming, trigram matching, reciprocal-rank fusion, proximity reranking, fuzzy correction, and smart snippets. The MCP interface includes execution, batching, indexing, search, fetching, statistics, diagnostics, upgrade, and purge tools. Context Mode supports multiple coding-agent platforms through MCP servers, native plugins, and platform-specific hooks, with automatic routing enforcement where hooks are available and instruction files for platforms without them. The repository states that processing and SQLite storage are local, with no account or telemetry requirement. It is licensed under the Elastic License 2.0, which permits use, modification, and distribution but restricts offering the software as a hosted or managed service and removing licensing notices.

Chrome DevTools Protocol is a browser-control protocol that, in the cited use, connects Browser Use Pi's JavaScript runtime directly to Chrome.
