Unreleased

Added

• 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. Features include detailed info, bi-directional search, type filtering, and simplified bridge output. (96788f3)
• Memory Operations: Added tools/endpoints for reading (read_memory) and writing (write_memory) to program memory. (454c739)
• Function Addressing Flexibility: MCP bridge now supports addressing functions by name or address. (4f3042f)
• API Version Check: Bridge script now verifies compatibility with the Java plugin (expects API v2). (fedd2d0)
• Enhanced Decompiler Controls: Added options for raw vs. clean pseudocode output and multiple simplification styles. (454c739)

Changed

• 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. (6c865c4)
• Standardized Responses: Unified all endpoints to use structured JSON and standardized HATEOAS links. (454c739, 4bc2267)
• Improved Error Handling: Enhanced error reporting and parameter validation across the API and bridge. (454c739, 4f3042f, 3df129f)
• API Documentation: Updated documentation to reflect the HATEOAS v2 API and new features. (28870e9, 3fd0cf4)

Fixed

• Variable Renaming: Fixed handling of variable operations in URL paths, allowing proper renaming of decompiler-generated variables through the API. (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)
• Endpoint Functionality: Addressed various issues including endpoint registration, handling of program-dependent endpoints, URL encoding, transaction management, and inconsistent response formats. (various commits, e.g., 4bc2267)
