What is the Chrome Debugger MCP Server?

Chrome breakpoint debugging MCP server for inspecting runtime values and stepping through code

The short version

chrome-debugger-mcp exposes Chrome DevTools Protocol primitives as MCP tools so an AI agent can attach to a real Chrome tab, pause execution, inspect scope values, evaluate expressions inside the current call frame, and step through code with runtime facts instead of guessing from static source.

guessing which tab to attach to
concluding behavior without inspecting runtime values
ending the turn between reloadPage() and waitForSpecificPause()

What it needs from you

Google Chrome installed locally - An MCP client that supports stdio servers and tool calling - Access to the application you want to debug - Local source access if you plan to insert temporary debugger; statements

Recorded tools

Check the linked publisher documentation and your connected client's tool list. Names and availability can vary with the server version and account permissions.

Tool	What it does
startDebuggingSession	returns the recommended debugging workflow and critical rules for agent behavior
launchChrome	launches a dedicated Chrome instance with remote debugging enabled
listTargets	lists available Chrome tabs and requires the user to pick one
connect	attaches to the confirmed tab
setBreakpoint	creates a CDP breakpoint without modifying source files
removeBreakpoint	removes a breakpoint created by setBreakpoint
reloadPage	reloads the current page through CDP
waitForSpecificPause	waits for the next pause and checks whether it matches a target file and line
waitForPause	waits for any pause without location matching
getScopeVariables	reads local, closure, and module scope values from the paused frame
evaluate	executes JavaScript in the paused call frame
resume	resumes execution after inspection
getStatus	non-blocking polling for connected or paused state
forcePause	requests a pause at the next JavaScript statement
