GDB

What is mcp_server_gdb?

mcp_server_gdb is a GDB/MI protocol server built on the MCP protocol. It provides remote application debugging capabilities, enhanced with AI assistants, allowing developers to debug applications remotely.

How to use mcp_server_gdb?

To use mcp_server_gdb, you can either download pre-built binaries from the release page or build it from source using cargo build --release and cargo run. Once built, simply run ./mcp-server-gdb. The server supports two transport modes: Stdio (default) and SSE (Server-Sent Events) at http://127.0.0.1:8080. You can configure the server's IP address, port, and GDB command timeout by modifying src/config.rs or using environment variables.

Key Features of mcp_server_gdb

Session Management: Create, get, and close GDB debug sessions.
Debug Control: Start, stop, continue, step into, and step over program execution.
Breakpoint Management: Set, get, and delete breakpoints.
Debug Information: Retrieve stack frame information, local variables, registers, and read memory contents.
Concurrent Multi-session Debugging: Supports debugging multiple sessions simultaneously.
AI Assistant Integration: Provides remote application debugging capabilities with AI assistants.
Built-in TUI (WIP): A work-in-progress Text User Interface to inspect agent behaviors for prompt improvement.

Use Cases of mcp_server_gdb

mcp_server_gdb is ideal for developers who need to:

Remotely debug applications using the GDB/MI protocol.
Manage multiple debugging sessions concurrently.
Leverage AI assistants for enhanced debugging workflows.
Control program execution and inspect debug information efficiently.

FAQ about mcp_server_gdb

Q: What is the MCP protocol? A: The MCP protocol is the underlying communication protocol used by mcp_server_gdb to expose GDB debugging capabilities.

Q: How can I configure the server? A: You can configure the server by modifying the src/config.rs file or by setting environment variables for server IP address, port, and GDB command timeout.

Q: Does it support concurrent debugging? A: Yes, mcp_server_gdb supports concurrent multi-session debugging.

Q: What kind of AI assistant features are available? A: The project provides remote application debugging capabilities with AI assistants, and there's a built-in TUI (WIP) to inspect agent behaviors for prompt improvement.
