Ghidra Mcp Analysis

Ghidra MCP Analysis

Implementation target

This skill assumes the Ghidra MCP implementation is LaurieWired/GhidraMCP. It uses:

• a Ghidra extension/plugin that exposes a local HTTP server from Ghidra, defaulting to http://127.0.0.1:8080/
• bridge_mcp_ghidra.py, a Python MCP bridge that talks to the Ghidra-side HTTP server
• stdio transport by default for Codex MCP, with optional SSE mode for clients that need it

Setup checklist

1. Install Ghidra and Python 3.
2. Download a LaurieWired/GhidraMCP release ZIP.
3. In Ghidra: File -> Install Extensions -> + -> select the GhidraMCP-*.zip release.
4. Restart Ghidra.
5. Enable GhidraMCPPlugin in File -> Configure -> Developer.
6. Optionally configure the Ghidra-side HTTP port with Edit -> Tool Options -> GhidraMCP HTTP Server.
7. Configure Codex to run the bridge:

tomlCopy code
[mcp_servers.ghidra]
command = "python3"
args = [
  "/ABSOLUTE_PATH_TO/GhidraMCP/bridge_mcp_ghidra.py",
  "--ghidra-server",
  "http://127.0.0.1:8080/"
]

Restart Codex and verify the ghidra MCP server is visible under /mcp before using live analysis.

Available LaurieWired/GhidraMCP capabilities

Use these capabilities by their MCP tool names when available:

Recommended workflow

1. Orient

   • Confirm Ghidra has the target program open and analyzed.
   • Use get_current_function / get_current_address when the user points at something in the UI.
   • Use list_segments, list_imports, list_exports, and filtered list_strings for initial context.

2. Survey efficiently

   • Prefer search_functions_by_name and list_strings(filter=...) over dumping everything.
   • Use pagination (offset, limit) for list_methods, list_classes, list_imports, list_exports, list_data_items, and list_strings.

3. Analyze functions

   • Use decompile_function_by_address when an address is known.
   • Use decompile_function when a stable symbol/function name is known.
   • Use disassemble_function when decompiler output is ambiguous, optimized out, or missing low-level details.

4. Trace relationships

   • Use get_xrefs_to / get_xrefs_from for address-oriented tracing.
   • Use get_function_xrefs for function-name-oriented tracing.
   • Build source -> transform -> sink chains with exact addresses and function names.

5. Annotate only with evidence

   • Use rename_function_by_address or rename_function when behavior is confirmed.
   • Use rename_variable, rename_data, set_function_prototype, and set_local_variable_type incrementally.
   • Use set_decompiler_comment or set_disassembly_comment to record reasoning at important addresses.

6. Report

   • Include addresses, original names, new names/comments/types applied, decompiler/disassembly evidence, xref paths, and confidence.
   • Separate confirmed behavior from hypotheses.
