Blackbox
AI-driven debugging for any language — set breakpoints, start/stop debug sessions, inspect variables, and navigate code via MCP tools.
Works with any Debug Adapter Protocol (DAP) compatible debugger: PHP, Node.js, Python, Go, C/C++, Java, and more.
Pre-release — This extension is under active development. Install the pre-release version to get the latest features.
Features
Breakpoint Management
- Set, remove, and list breakpoints with conditions and log messages
- Batch operations for multiple breakpoints at once
Debug Session Control
- Start, stop, restart debug sessions for any language
- Continue, pause, step over, step into, step out
- Language-agnostic — works with any VS Code debug adapter
Variable Inspection
- Get all variables in the current scope
- Deep inspect nested objects and arrays
- Evaluate arbitrary expressions at breakpoints
- Persistent watch expressions across steps
Editor & Workspace
- Open files at specific lines
- Find files by glob pattern
- Get diagnostics (errors/warnings) from all language services
How It Works
Blackbox exposes debugging tools to AI models through two transport paths:
- VS Code Chat — Tools are available as
#tool_name references in Copilot Chat
- MCP Server — A stdio-based MCP server for external AI clients (Cursor, Claude Desktop, etc.)
Requirements
- VS Code 1.99.0 or later
- A debug adapter extension for your language (e.g., PHP Debug, Node.js Debugger)
