No release targets Ghidra 12.1.2 - extension fails to install with a version mismatch
Author: tcyph3rCreated Aug 6, 2026Updated Sep 10, 2026
The latest release (1.4) declares version=11.3.2 in extension.properties. There's no release built against Ghidra 12.1.2, so on a 12.1.2 install, Ghidra's Install Extensions dialog rejects it outright:
Extension version mismatch. Name: GhidraMCP Extension version: 11.3.2. Ghidra version: 12.1.2. Did not installCould you cut a release targeting 12.1.2? Happy to test against it once available.
As a workaround in the meantime, I built from source against my local 12.1.2 install (copying the 8 required jars into lib/ and rebuilding with Maven) - that worked once I set version=12.1.2 in extension.properties. Worth noting for the README: the rejection message above cites the version field's value, not ghidraVersion - easy to update the wrong one first since ghidraVersion reads as the more obvious candidate.
