### Description (declared)

# gdb-mcp

Model Context Protocol server that wraps `gdb` so an LLM can drive live debugging
sessions. The server exposes tools for starting a session on a binary, attaching
to an existing PID, running ad-hoc commands, batching commands, checking status,
and shutting sessions down.

> Requires `gdb` on the host and the `mcp` python package (v1+).

## Setup

You can install either inside a virtualenv (recommended) or directly:

```bash
# optional but recommended
python -m venv .venv
. .venv/bin/activate

pip install -e .
# or: pip install .
```

## Running the MCP server

You can start the server directly:

```bash
gdb-mcp
# or
python -m gdb_mcp.server
```

The server uses stdio for transport (the default for most MCP clients). Point
your MCP client configuration at the command above.

### One-shot client configuration

Run `gdb-mcp --install` to add the server to any detected MCP-aware clients
without editing config files by hand. The installer currently knows how to
update:

- Codex CLI (`~/.codex/config.toml`)
- Claude Desktop configs (common Linux/macOS paths)
- Cursor / Windsurf MCP config files (if present)

Use `--install-command /custom/path/to/gdb-mcp` or `--install-args ...` if you
need to override what gets written.

## Exposed tools

- `start_binary(binary_path, args=None, cwd=None, load_init=True, start_timeout=30.0, prompt=None, force_prompt=True)` – launch gdb
  against a target binary (with optional args) and return a session id and the
  initial banner. Set `load_init=False` to skip user gdbinit (default is to load
  it so helpers like GEF/pwndbg remain enabled). Increase `start_timeout` if
  loading extensions takes longer to reach the first prompt. Use `prompt` to
  force a specific prompt string (defaults cover `(gdb)`, `(pwndbg)`, and
  `gef>`). `force_prompt` sets the prompt to the chosen value after startup to
  avoid timeouts from customized prompts (e.g., pwndbg); set `force_prompt=False`
  if you need to keep your custom prompt unchanged.
