Gdb Mcp — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited Gdb Mcp (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

The primary manifest — the file an agent reads to learn what this artifact does.
A Model Context Protocol server that provides debugging functionality for both GDB and LLDB debuggers, for use with Claude Desktop, VSCode Copilot, or other AI assistants.

}This project includes experimental native LLDB support alongside GDB, with automatic debugger selection.

To enable LLDB support on macOS, install LLVM (which includes LLDB) and python via Homebrew:
# Install LLDB for supporting python3.14 bindings
brew install llvm python3
# Install MCP and debugging dependencies
pip3 install mcp pygdbmi --break-system-packagesdebugger_status(): Show available debuggers and their statusdebugger_start(): Start debugging session with auto-detected debuggerdebugger_terminate(session_id): Terminate debugging sessiondebugger_list_sessions(): List all active debugging sessionsdebugger_command(session_id, command): Execute debugger commandlldb_start(): Start new LLDB debugging sessionlldb_terminate(session_id): Terminate LLDB debugging sessionlldb_list_sessions(): List all active LLDB sessionslldb_command(session_id, command): Execute arbitrary LLDB commandgdb_start(gdb_path): Start new GDB debugging sessiongdb_terminate(session_id): Terminate GDB debugging sessiongdb_list_sessions(): List all active GDB sessionsgdb_command(session_id, command): Execute any GDB commandUse *_command() functions for all advanced debugger operations, your LLM client should already know how to use it, but it doesn't hurt to mention it.You can verify debugger availability:
