Overview

LLDB-MCP is a tool that integrates the LLDB debugger with Claude's Model Context Protocol (MCP). This integration allows Claude to start, control, and interact with LLDB debugging sessions directly, enabling AI-assisted debugging workflows. The tool provides a comprehensive set of commands for working with LLDB, including session management, program loading, execution control, inspection, thread management, and miscellaneous operations. The tool can create and manage multiple LLDB debugging sessions, load executables and attach to running processes, and load core dump files for post-mortem analysis. It also supports fine-grained control over program execution, memory examination, and disassembly. Once installed and configured, users can interact with LLDB through Claude using natural language. The basic workflow involves starting a new LLDB session, loading a program, setting breakpoints, running the program, inspecting variables and memory, and controlling execution. LLDB-MCP supports a range of commands, including starting and terminating sessions, loading programs, running execution, setting breakpoints and watchpoints, inspecting memory and registers, and executing arbitrary LLDB commands.

Q&A

Does lldb-mcp support attaching to a running process?

The tool can load executables and attach to already running processes, providing full control over execution and inspection via natural language commands.

Asked by Elena Rossi · Feb 14, 2026

What is required to use lldb-mcp with Claude?

You must install lldb-mcp and configure Claude’s Model Context Protocol (MCP) server; without this setup the integration will not function.

Asked by Jarrah Whitlock · Jan 15, 2026

Can lldb-mcp load a core dump for post‑mortem analysis?

Yes, the tool supports loading core dump files so you can inspect memory and perform disassembly after a crash using Claude.

Asked by Stella Papadopoulos · Jan 6, 2026

How many LLDB debugging sessions can I manage simultaneously with lldb-mcp?

lldb-mcp allows the creation and management of multiple LLDB debugging sessions at once, letting you work on several programs or core dumps concurrently.
