MCP GDB Server

A Model Context Protocol (MCP) server that provides GDB debugging functionality for use with Claude or other AI assistants.

Features

  • Start and manage GDB debugging sessions
  • Load programs and core dumps for analysis
  • Set breakpoints, step through code, and examine memory
  • View call stacks, variables, and registers
  • Execute arbitrary GDB commands

Installation

# Clone the repository git clone https://github.com/signal-slot/mcp-gdb.git cd mcp-gdb # Install dependencies npm install # Build the project npm run build

Usage

Using with Claude or other MCP-enabled assistants

  1. Configure the MCP settings in the Claude desktop app or browser extension to include this server:
{ "mcpServers": { "gdb": { "command": "node", "args": ["/path/to/mcp-gdb/build/index.js"], "disabled": false } } }
  1. Restart Claude or refresh the page.
  2. Now you can use the GDB tools in your conversations with Claude.

Example Commands

Here are some examples of using the GDB MCP server through Claude:

Starting a GDB session
Use gdb_start to start a new debugging session
Loading a program
Use gdb_load to load /path/to/my/program with the sessionId that was returned from gdb_start
Setting a breakpoint
Use gdb_set_breakpoint to set a breakpoint at main in the active GDB session
Running the program
Use gdb_continue to start execution
Examining variables
Use gdb_print to evaluate the expression "my_variable" in the current context
Getting a backtrace
Use gdb_backtrace to see the current call stack
Terminating the session
Use gdb_terminate to end the debugging session

Supported GDB Commands

  • gdb_start: Start a new GDB session
  • gdb_load: Load a program into GDB
  • gdb_command: Execute an arbitrary GDB command
  • gdb_terminate: Terminate a GDB session
  • gdb_list_sessions: List all active GDB sessions
  • gdb_attach: Attach to a running process
  • gdb_load_core: Load a core dump file
  • gdb_set_breakpoint: Set a breakpoint
  • gdb_continue: Continue program execution
  • gdb_step: Step program execution
  • gdb_next: Step over function calls
  • gdb_finish: Execute until the current function returns
  • gdb_backtrace: Show call stack
  • gdb_print: Print value of expression
  • gdb_examine: Examine memory
  • gdb_info_registers: Display registers
