From 384f8b272fb9697374fa0315192884a0caee9d45 Mon Sep 17 00:00:00 2001 From: Teal Bauer Date: Tue, 15 Apr 2025 11:39:09 +0200 Subject: [PATCH] fix: update callgraph endpoint to accept both name and address parameters - Modified ProgramEndpoints.java to support the name and address parameters - Updated bridge MCP tool analysis_get_callgraph to use both parameters - Updated tests to verify functionality with both parameters - Added the change to CHANGELOG.md --- CHANGELOG.md | 11 +- bridge_mcp_hydra.py | 122 ++++++++- error.tmp | 125 +++++++++ .../ghidra/endpoints/ProgramEndpoints.java | 51 +++- test_http_api.py | 56 ++++ test_mcp_client.py | 256 ++++++++++++------ 6 files changed, 522 insertions(+), 99 deletions(-) create mode 100644 error.tmp diff --git a/CHANGELOG.md b/CHANGELOG.md index 25c37c9..f8be978 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -7,6 +7,11 @@ The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/). ## [Unreleased] ### Added +- **MCP Integration Refactor:** Refactored the Python bridge for improved MCP integration. (337f89e) + - Introduced MCP resources for loading context (e.g., instances, functions, disassembly). + - Added namespaced tools (e.g., `instance.*`, `function.*`, `data.*`) for better organization and discoverability. + - Implemented a "current working instance" concept to simplify commands by implicitly targeting the active Ghidra instance. +- **Analysis Prompts:** Added pre-defined prompts for common analysis tasks, including `reverse_engineer_binary` for comprehensive analysis. (337f89e, 3134581) - **String Data Listing:** Added a new endpoint to list string data in the binary, with pagination and filtering by content. Python bridge support via `list_strings()` function. (f71f4aa) - **Comprehensive Data Manipulation:** Added tools/endpoints for creating (`create_data`), deleting (`delete_data`), renaming (`rename_data`), changing type (`set_data_type`), and combined updates (`update_data`) for data items. Supports common types (byte, word, dword, string, etc.). (6c28553, 5797fb3, 28870e9) - **Enhanced Cross-Reference (Xrefs) Analysis:** Implemented accurate xref tools (`get_references_to`, `get_references_from`) using Ghidra's ReferenceManager.

(337f89e) - **Breaking: HATEOAS API v2 & Bridge Update:** Migrated fully to a HATEOAS-driven API (v2). The Python bridge (`bridge_mcp_hydra.py`) now *exclusively* uses this API, removing legacy support. Responses are simplified for AI agents, including text representations for structured data (e.g., disassembly). All endpoints require HATEOAS compliance (e.g., `_links`). (4bc2267, 4f3042f) - **Optimized Variable Listing:** Improved performance of the `/variables` endpoint with efficient pagination and a `globalOnly` filter.

(f377a34, c4d170c) -- **Function Creation:** Improved function creation by attempting to disassemble memory before creating functions, which helps in correctly identifying function boundaries. (25f353a) - **Real Instruction Disassembly:** The `/disassembly` endpoint now provides actual instruction disassembly instead of placeholders. (3df129f) - **Ghidra 11+ Compatibility:** Resolved various API compatibility issues, particularly for cross-references (`XrefsEndpoints`). (5dc59ce, 2b1fe6c, 0eaa19a, 9443101) - **Data Operations:** Fixed issues with HTTP request body consumption, parameter naming (`type` vs `dataType`), and name preservation during type changes. (28870e9) - **Function Commenting:** Corrected `set_decompiler_comment` to apply comments at the function level. (2a1607c) +- **Call Graph Parameter Handling:** Updated the CallGraph endpoint to properly accept both function name and address parameters for flexibility. (fa8cc64) - **Endpoint Functionality:** Addressed various issues including endpoint registration, handling of program-dependent endpoints, URL encoding, transaction management, and inconsistent response formats.
