ida-mcp-rs

Headless IDA Pro MCP server for AI-powered reverse engineering.

Prerequisites

• IDA Pro 9.2+ with valid license (9.3sp1 recommended)

Getting Started

Install

macOS / Linux (via Homebrew)

brew install blacktop/tap/ida-mcp        # Latest (IDA 9.3/9.3sp1)
brew install blacktop/tap/ida-mcp@9.2    # IDA 9.2

Windows (via Scoop)

scoop bucket add blacktop https://github.com/blacktop/scoop-bucket
scoop install blacktop/ida-mcp

Windows note: See the Windows platform setup section below for DLL discovery options.

macOS / Linux (via Nix)

nix shell github:blacktop/nur#ida-mcp \
  --extra-experimental-features 'nix-command flakes'

Linux (via Snap)

sudo snap install ida-mcp
sudo snap connect ida-mcp:dot-idapro   # grant access to ~/.idapro (license)

Strict confinement. Requires IDA Pro installed under $HOME (installer default ~/ida-pro-9.3). For IDA in /opt/ or system paths, use Homebrew or Nix.

Direct download — grab the archive for your platform from GitHub Releases.

Build from source

See docs/BUILDING.md.

ida-mcp versions mirror IDA Pro versions (v9.3.x for IDA 9.3, v9.2.x for IDA 9.2). A version mismatch is detected at startup with a clear error message. Scoop and NUR publish the latest version. For older IDA versions, use the matching GitHub Release or the versioned Homebrew cask.

Platform Setup

macOS

Standard IDA installations in /Applications work automatically:

claude mcp add ida -- ida-mcp

If you see Library not loaded: @rpath/libida.dylib, set DYLD_LIBRARY_PATH to your IDA path:

claude mcp add ida -e DYLD_LIBRARY_PATH='/path/to/IDA.app/Contents/MacOS' -- ida-mcp

Supported paths (auto-detected):

• /Applications/IDA Professional 9.3.app/Contents/MacOS
• /Applications/IDA Home 9.3.app/Contents/MacOS
• /Applications/IDA Essential 9.3.app/Contents/MacOS
• /Applications/IDA Professional 9.2.app/Contents/MacOS

Linux

The IDA installer defaults to ~/ida-pro-9.3 — the launcher script auto-detects this:

claude mcp add ida -- ida-mcp

For non-default install locations, set IDADIR:

claude mcp add ida -e IDADIR='/path/to/ida' -- ida-mcp

Resolution order: $IDADIR → ~/ida-pro-9.3 → /opt/ida-pro-9.3 and other RUNPATH fallbacks.

Windows

Option A — Install ida-mcp.exe into your IDA directory (simplest, no env setup needed):

# Copy the binary next to ida.dll / idalib.dll
copy ida-mcp.exe "C:\Program Files\IDA Professional 9.3\"
claude mcp add ida -- "C:\Program Files\IDA Professional 9.3\ida-mcp.exe"

Option B — Install via Scoop (auto-detects IDA and sets IDADIR):

scoop bucket add blacktop https://github.com/blacktop/scoop-bucket
scoop install blacktop/ida-mcp
claude mcp add ida -- ida-mcp

Option C — Set IDADIR manually:

# Persistent (survives reboots)
setx IDADIR "C:\Program Files\IDA Professional 9.3"
# Then restart your terminal
claude mcp add ida -- ida-mcp

Windows requires ida.dll and idalib.dll to be discoverable at startup. Placing ida-mcp.exe in the IDA directory is the easiest approach. Otherwise, the IDA directory must be on PATH or pointed to by IDADIR.

Common IDA paths:

• C:\Program Files\IDA Professional 9.3
• C:\Program Files\IDA Pro 9.3
• C:\Program Files\IDA Home 9.3

Runtime Requirements

The binary links against IDA's libraries at runtime. Standard installation paths are auto-detected via baked RPATHs. For non-standard paths:

Platform	Library	Fallback Configuration
macOS	libida.dylib	DYLD_LIBRARY_PATH
Linux	libida.so	IDADIR (launcher reads it) or LD_LIBRARY_PATH
Windows	ida.dll	Place exe in IDA dir, set IDADIR, or add IDA dir to PATH

Configure your AI agent

Claude Code

claude mcp add ida -- ida-mcp

Codex CLI

codex mcp add ida -- ida-mcp

Gemini CLI

gemini mcp add ida -- ida-mcp

Cursor

Add to .cursor/mcp.json:

{
  "mcpServers": {
    "ida": { "command": "ida-mcp" }
  }
}

Usage

Once configured, you can analyze binaries through your AI agent:

# Open a binary (returns quickly — analysis runs separately)
open_idb(path: "~/samples/malware")

# These work immediately, no analysis needed
list_functions(limit: 20)
disasm_by_name(name: "main", count: 20)
strings(limit: 10)

# For xrefs/decompile on large binaries, run analysis in background
analyze_funcs(background: true)   # returns task_id
task_status(task_id: "analyze-1") # poll progress

# Decompile (requires Hex-Rays + completed analysis)
decompile(address: "0x100000f00")

# Discover more tools
tool_catalog(query: "find callers")

dyld_shared_cache analysis

open_dsc opens a single module from Apple's dyld_shared_cache. On first use it runs idat in the background to create the .i64 (this can take minutes). Subsequent opens are instant.

# Open a module from the DSC
open_dsc(path: "/path/to/dyld_shared_cache_arm64e", arch: "arm64e",
         module: "/usr/lib/libobjc.A.dylib")

# If a background task was started, poll until done
task_status(task_id: "dsc-1")

# Load additional frameworks for cross-module references
open_dsc(path: "/path/to/dyld_shared_cache_arm64e", arch: "arm64e",
         module: "/usr/lib/libobjc.A.dylib",
         frameworks: ["/System/Library/Frameworks/Foundation.framework/Foundation"])

# Incrementally load another DSC dylib into an already-open database
dsc_add_dylib(module: "/usr/lib/libSystem.B.dylib")

# Incrementally load a DSC data/GOT/stub region by address
dsc_add_region(address: "0x180116000")

# After dsc_add_dylib/dsc_add_region, confirm analysis readiness
analysis_status()

Requirements:

• idat binary (from IDA installation) must be available via $IDADIR or standard install paths
• The DSC loader and dscu plugin (bundled with IDA 9.x)

IDAPython scripting

run_script executes Python code in the open database via IDA's IDAPython engine. stdout and stderr are captured.

# Inline script
run_script(code: "import idautils\nfor f in idautils.Functions():\n    print(hex(f))")

# Run a .py file from disk
run_script(file: "/path/to/analysis_script.py")

# With timeout (default 120s, max 600s)
run_script(code: "import ida_bytes; print(ida_bytes.get_bytes(0x1000, 16).hex())",
           timeout_secs: 30)

All ida_* modules, idc, and idautils are available. See the IDAPython API reference.
