Release / 6 Oct 2025

IDA Pro MCP 1.4.0

Analyze binaries through MCP without opening the IDA Pro GUI.

Before you upgrade to 1.4.0

2 to fix

Replace `search_strings(pattern, offset, count)` with `list_strings_filter(offset, count, filter)`; this release supports case-insensitive substring filters, not regex.

Action requiredList and search strings in an IDA database.Affects: Scripts calling `search_strings` or using regex string searchesInferred

Update parsers for structured disassembly with `lines`, `stack_frame`, arguments and return type instead of the previous text response.

Action requiredInspect functions, disassembly, pseudocode, and cross-references in an IDA database.Affects: Scripts parsing `disassemble_function` responsesInferred

What changed in 1.4.0

Adds `idalib-mcp` for headless analysis and debugger tools enabled with `--unsafe`. String-search calls and disassembly response formats change.

Also: Debugger control, memory reads, stack and structure inspection, assembly patches, and more client integrations.

Use tag 1.4.0 with Python 3.11+ and IDA Pro 8.3+; headless analysis needs idalib. IDA Free is unsupported.

New things you can do

Run `idalib-mcp` with the input binary path and connect through SSE.

AddedAnalyze a binary without opening the IDA Pro GUI.
