Chrome Debug MCP
MCP server that exposes Chrome DevTools Protocol (CDP) capabilities to AI agents, enabling agents to attach to Chrome browser sessions, inspect DOM elements, capture network traffic, execute JavaScript in page context, take screenshots, and perform debugging operations through structured MCP tool calls.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Full browser session access including cookies, passwords stored in page context, and authenticated sessions. Keep debugging port local only. High-trust tool for development environments.
⚡ Reliability
Best When
A developer agent needs to debug live web applications by inspecting Chrome's DevTools data — inspecting DOM, capturing network traffic, or executing JS in page context for debugging workflows.
Avoid When
You need full browser automation (navigation, form filling) — use Playwright or Puppeteer MCPs which handle the full automation lifecycle better.
Use Cases
- • Debugging web applications by inspecting DOM state from debugging agents
- • Capturing and analyzing network requests in Chrome from performance agents
- • Executing JavaScript in browser context from test automation agents
- • Taking page screenshots and analyzing visual state from QA agents
Not For
- • Full browser automation (use Playwright MCP or Puppeteer MCP for end-to-end automation)
- • Production environments without Chrome installed
- • Non-Chrome browsers (Firefox, Safari need different DevTools protocols)
Interface
Authentication
No authentication — attaches to locally running Chrome with remote debugging enabled. Requires Chrome launched with --remote-debugging-port flag.
Pricing
Free open source Chrome DevTools Protocol MCP bridge.
Agent Metadata
Known Gotchas
- ⚠ Chrome must be launched with --remote-debugging-port=9222 flag before connecting
- ⚠ JS execution in page context can modify page state — use carefully in production debugging
- ⚠ Chrome updates can change CDP behavior — test with each Chrome version update
- ⚠ Only attaches to one Chrome tab/session at a time by default
