MCP Node.js Debugger

MCPOfficialOpen Source17.5

by liuchongchong1995 • Testing & QA

An MCP server that gives Cursor or Claude Code agents runtime access to a Node.js process for interactive debugging.

Example Use Cases

1
Set breakpoints and step through a live Node.js process to inspect call stacks and variable state.
2
Run small JavaScript snippets in the context of a running Node.js app to check values or reproduce issues.
3
Diagnose runtime configuration problems (for example, database connection strings or environment variables) without manual terminal access.

Description

This MCP exposes a Node.js debugger over the MCP protocol so agents (Cursor, Claude Code) can set breakpoints, inspect state, execute snippets, and view console output on a running Node process started with --inspect. It integrates with Cursor and Claude Code via an npm-distributed package (@hyperdrive-eng/mcp-nodejs-debugger) and streamlines diagnosing runtime issues (e.g., DB connection errors) without leaving the chat interface. Useful for live debugging, capturing runtime variables, and iterating fixes interactively.
