mcpyghidra 0.7.2

Ghidra MCP server.

MCPyGhidra

An MCP (Model Context Protocol) server that exposes Ghidra reverse-engineering capabilities to LLM clients. Built on pyghidra-decaf.

MCPyGhidra exposes binary analysis capabilities via MCP: decompilation, disassembly, symbol lookup, cross-references, type inspection, binary patching, and scriptable analysis.

Related project: If you use IDA Pro rather than Ghidra, see MCPyIDA for an equivalent MCP server for IDA Pro.

Prerequisites

• Ghidra a recent release (tested with Ghidra 11.x+; download)
• Java a compatible JDK (bundled with Ghidra)
• Python 3.10–3.13
• pyghidra-decaf (installed via PyPI alongside mcpyghidra)

Installation

pip install mcpyghidra

Then configure your Ghidra installation:

export GHIDRA_INSTALL_DIR=/path/to/ghidra_12.0_PUBLIC

For detailed setup, see docs/installation.md.

Quick Start

Headless Mode

Launch the MCP server in headless mode for non-interactive analysis:

export GHIDRA_INSTALL_DIR=/path/to/ghidra
mcpyghidra-headless --binary /path/to/firmware.elf

The server prints a JSON readiness signal to stdout:

{"status": "ready", "host": "127.0.0.1", "port": 6050, "binary": "/path/to/firmware.elf"}

Then configure your MCP client to connect to http://127.0.0.1:6050/mcp.

With an MCP Client

Point any MCP-compatible client at the running server:

{
  "mcpServers": {
    "ghidra": {
      "type": "streamable-http",
      "url": "http://127.0.0.1:6050/mcp"
    }
  }
}

See docs/mcp-client-config.md for client-specific examples.

What's Exposed

MCPyGhidra exposes 26 tools organized into categories:

• Listing & context: list entries, inspect binary metadata, resolve functions
• Analysis: decompile, disassemble, cross-references, control-flow graphs
• Types: type enumeration and detailed inspection
• Modification: rename symbols, update variables, set comments, patch instructions
• Scripting: Python code execution with back-to-client RPC callbacks
• Search: binary pattern and instruction sequence matching

See docs/tools-reference.md for full details.

Troubleshooting

• GHIDRA_INSTALL_DIR not set — point it at your Ghidra install: export GHIDRA_INSTALL_DIR=/path/to/ghidra_12.0_PUBLIC.
• Client can't connect — confirm the server is running and reachable at the Streamable HTTP endpoint http://127.0.0.1:6050/mcp.
• Server startup hangs — analyzing large binaries can take minutes; try a small binary (e.g. mcpyghidra-headless --binary /bin/ls) to verify the setup.

See docs/installation.md and docs/quickstart.md for the full troubleshooting guides.
