Your AI can already read and write code. With inspector-mcp it can also run it, pause it, and look inside it.

Connect any MCP-compatible AI agent to a running Node.js process. Set breakpoints on your TypeScript source files, step through execution line by line, inspect every variable in scope, and read console output — all through natural language, without leaving your AI chat.

• Source-map aware breakpoints — set breakpoints using your .ts file paths; the server resolves them to the compiled .js positions automatically
• Full step execution — step over, step into, step out, continue
• Variable inspection — local, closure, and global scope; drill into nested objects
• Expression evaluation — run any JS expression in the context of the paused frame
• Console buffer — last 1,000 log entries, filterable by level and text
• Auto-reconnect — survives process restarts and re-reg
