EDB Debugger

CI PyPI Python License: MIT GDB MCP Docker Changelog

About

EDB (Evan's Debugger) is a feature-rich, open-source GUI debugger for Linux (x86/x86-64), known for its intuitive interface, powerful plugin system (22 plugins), and extensive debugging capabilities — breakpoints, memory analysis, ROP tool, heap analyzer, and more. However, EDB has always been limited to manual GUI interaction — until now.

EDB Debugger MCP bridges EDB's debugging engine with modern AI via the Model Context Protocol (MCP). Every EDB feature is exposed as a tool callable by an AI assistant — Claude Desktop, Cursor, or any MCP host — effectively giving AI a debugger's intuition. The server exposes 26 composite debugging tools (19 edb_ + 7 pwntools_) that replace 157 flat primitives using parameter-driven dispatch for minimal context overhead (~4× token savings vs flat tool catalogs).

Behind the scenes, it translates AI requests into GDB MI commands via a high-performance async backend, then formats results back as structured data. Combined with pwntools integration (7 composite tools covering ELF analysis, ROP, shellcode, assembly, packing, tubes, and utilities), it becomes a complete AI-powered reverse engineering workstation.

Complete RE workflow: load binary → disassemble → ROP search → set breakpoint → run → read registers → dump stack → backtrace → generate shellcode.

Tool call arguments and their structured results displayed side by side for clarity.

Installation

# Clone the repository
git clone https://github.com/oakkaya/edb-debugger-mcp.git
cd edb-debugger-mcp

# Install dependencies
pip install -r requirements.txt

# (Optional) Install with pip
pip install -e .

Usage

Standalone

python edb_debugger_mcp.py

This starts the MCP server on stdio, ready to accept MCP protocol messages.

Testing

# Compile a test binary
gcc -g -o /tmp/test_bin /path/to/test.c

# Then run the server manually or use an MCP client

Docker Usage

A pre-built Docker image is available on GitHub Container Registry.

# Pull the latest image
docker pull ghcr.io/oakkaya/edb-debugger-mcp:latest

# Run the MCP server (stdio mode, for MCP hosts)
docker run -i ghcr.io/oakkaya/edb-debugger-mcp

# Run with a specific version tag
docker run -i ghcr.io/oakkaya/edb-debugger-mcp:latest

# Run interactively with a shell for debugging
docker run --rm -it \
  --security-opt seccomp=unconfined \
  --cap-add=SYS_PTRACE \
  ghcr.io/oakkaya/edb-debugger-mcp /bin/bash

The image is built from python:3.13-slim with GDB pre-installed. It is automatically rebuilt and published on every GitHub release (v* tag).

The server uses GDB's MI (Machine Interface) protocol (--interpreter=mi2) to communicate with GDB as a subprocess. The backend:

• Sends MI/CLI commands via stdin, parses structured MI responses
• Handles *stopped async events for breakpoint hits
• Manages process lifecycle (start, kill, detach)
• Provides readelf-based file offset ↔ VA conversion

Note: The EDB action/dialog/view counts listed in this README cover all of EDB's UI elements. Since this project is an MCP server, UI-only features (About dialog, font selector, Reset UI, window layout) cannot be mapped. All functional debugging capabilities (breakpoint, register, memory, stack, thread, expression, patching, analysis, ROP, session) are 100% covered.

Binary Ninja Integration

⚠ Experimental / untested — Binary Ninja is a commercial product (not available in this environment). The plugin code is structurally complete and follows the BN plugin API, but has not been verified at runtime. PRs welcome.

The binaryninja_mcp/ directory contains a full Binary Ninja plugin that bridges the decompiler with the live debugger. Features:

• Register overlay — HLIL comments with live register values
• Single-click breakpoints — Right-click to toggle software/hardware breakpoints
• In-place patching — NOP, assemble, range-NOP from the disassembly context menu
• Step control — Step into/over/out, run, pause via Plugins menu
• Sidebar widget — Live register summary in the "EDB Debugger" tab

Install: ln -s $(pwd)/binaryninja_mcp ~/.binaryninja/plugins/edb-debugger-bridge

• Toggle Breakpoint — Set/clear breakpoints at the cursor address
• In-place patching — NOP, assemble instructions
• Step/run control — Step into/over, run, pause
• Register & memory inspection — Live register values, memory hex dump

Install: in Ghidra with pyhidra, run ghidra_mcp/ghidra_bridge.py via the Python interpreter, then use the newly registered actions from the right-click menu.

Web UI

⚠ Experimental

The web_ui/ directory provides a browser-based debugger frontend (FastAPI + vanilla JS). No JS framework required.

cd web_ui
pip install -r requirements.txt
python server.py

• Categorized tool sidebar — Program, Breakpoints, Run/Step, Registers/Memory, Analysis, Pwntools
• Dynamic parameter forms — Tools with arguments show input fields auto-generated from the tool schema
• Dark theme — Clean, readable interface
• Live results — Output streams into the result panel with auto-scroll

x64dbg Integration

⚠ Experimental / untested — Windows-only. Requires x64dbg with x64dbgpy. No test environment available.

The x64dbg_mcp/ directory contains an x64dbgpy plugin. Features:

• Start/Stop Bridge — Connect to the MCP server
• Breakpoint control — Toggle, clear all
• Patching — NOP, assemble at cursor
• Step/run — Step into/over, run, pause
• Inspection — Registers, memory at selection

Install: copy x64dbg_mcp/ to x64dbg's py-plugins/ directory. The "EDB Bridge" submenu appears under Plugins.

Quick Start

# Install
pip install edb-debugger-mcp

# Start the MCP server (standalone)
edb-debugger-mcp

# Or with Web UI
pip install "edb-debugger-mcp[web]"
python3 -m web_ui.server

3-step CTF solve with AI:

User:  Load /challenge/bof and analyze it
AI:    → edb_load_program(path="/challenge/bof")
       → edb_disassemble("main")  → finds gets() call
       → edb_list_functions()     → finds win() at 0x4011b6

User:  Build exploit
AI:    → pwntools_cyclic(200)     → generates pattern
       → pwntools_cyclic_find("0x6161616c") → offset = 136
       → pwntools_flat([0xdeadbeef]*34 + [0x4011b6]) → payload

User:  Test it
AI:    → edb_run(args=$(python3 -c "print('A'*136 + '\xb6\x11\x40')"))
       → edb_set_breakpoint("win")
       → edb_continue() → breaks at win → flag printed!

IDA Pro Integration

✅ Tested with IDA Pro 9.3 — IDAPython imports (ida_pro, idaapi, idc, idautils), all 13 actions register under Edit -> EDB Debugger, MCP subprocess bridge connects with 26 composite tools, step/run/breakpoint/patch actions work, headless mode works with ida -c -A -S<script> under xvfb.

The ida_mcp/ directory contains an IDAPython plugin that connects IDA Pro to the MCP server. Features:

Install: copy ida_mcp/ to IDA's plugin directory:

cp -r ida_mcp ~/.idapro/plugins/edb_debugger_bridge

After starting the bridge (Edit -> EDB Debugger -> Start Bridge), all actions are available from the Edit -> EDB Debugger menu.

VS Code Extension

⚠ Experimental

The vscode-edb-mcp/ directory contains a VS Code extension that provides a debugger frontend inside VS Code. Features:

• Start/Stop Bridge — Spawn and kill the MCP subprocess
• Debugger Panel — WebView panel for debugging commands
• Execution control — Run/continue (F5), pause, step into (F11), step over (F10)
