Idac

idac

[](https://pypi.org/project/idac/)  

The IDA Pro CLI built for agents and humans. One Unix socket — no JSON-RPC framing, no sidecar daemon, no MCP server. Just `idac decompile "sub_08041337"` from any shell or agent.

`idac` is in early alpha and actively developed. It is already useful day to day, but the CLI surface may still change between releases.

Why idac

• Not an MCP server — compose with the shell you already have: pipes, xargs, jq, and your agent's existing tool-use loop. No server to run, no protocol to babysit.
• Agent-native by default — every command can emit structured JSON (-j), and a bundled skill teaches Claude Code and Codex to drive idac instead of guessing at raw IDAPython.
• Safe mutations — every mutation supports preview, which applies the change under IDA's undo, captures the before/after, and rolls it back. Dry-run any rename, retype, or prototype change before committing it.
• Built for batches — recover an entire class hierarchy, retype a hundred locals, or decompile every Handler_* in one invocation against a shared context.
• Live or headless — the same commands work against a running IDA GUI session or a saved .i64/.idb. Switch targets with -c; with one GUI open, omit it entirely.

Demo

Run this against the fixture committed in this repo:

idac decompilemany "CreateHandler_" --out-dir decomp/ -c "db:fixtures/idb/handler_hierarchy.i64"

Every matching function is decompiled into its own `.c` f
