dsh-jj

Most AI assistants fall back to a git mindset when doing version control — stage, commit, branch. For developers who have already moved to jj (Jujutsu) as their daily VCS, that mismatch turns every AI-assisted commit or rebase into a forced workaround. dsh-jj closes that gap: it wraps your local jj CLI in a zero-dependency MCP stdio server so the model operates natively inside the jj change-and-bookmark model instead of simulating git.

The server is built on the Node standard library alone, with no third-party runtime dependencies. Every invocation goes through a spawn array, bypassing the shell entirely, which makes argument injection a non-issue. The fourteen tools span the full jj workflow — from jj_status, jj_log, and jj_diff through jj_rebase, jj_push, and jj_bookmark — with a catch-all jj_run for advanced subcommands like split, workspace, and op restore. Dangerous config flags are filtered at the entry point, and the undoable design of jj keeps the blast radius of any mistake small.

If you already manage repositories with jj and want your AI assistant to understand the jj working model rather than degenerate into a git emulator, dsh-jj is purpose-built for that. It also works as a standalone MCP stdio server, so you can plug it into Claude Code or Codex outside the DSH ecosystem.
