mcp-server-git-rs

A fast Rust MCP server that exposes git repository operations over stdio. Drop-in replacement for the Python mcp-server-git reference server: same tool names, same input schemas, same stdio transport.

Single static binary. On an Apple M3, ~5 ms cold start vs ~375 ms for the Python server, and warm tools/call round-trips of 1–7 ms across the read-only tools we measure. Numbers, methodology, and a reproducible harness are in bench/.

Highlights

• 52 tools total — the full Python reference set plus git_push, plus 39 more across 8 opt-in groups (inspection, tags, stash, remotes, history, branches-extended, worktrees, notes). Default invocation still exposes only the core 13 so smaller agents don't see a 50-tool list.
• Staged via --features — one CLI flag, comma-separated values, all shorthand. Single binary, gated at runtime.
• Reproducible benchmarks — bench/run.py measures cold start + warm-call p50/p95 against uvx mcp-server-git on whatever fixture you point it at. The "60×" claim is now a number you can verify, not a marketing line.
• Security-hardened — canonicalised repo scoping (--repository), flag-injection rejection, revparse validation. Matches the Python server's invariants one-to-one and applies them to every new tool.
• Works with 12+ MCP-speaking agents — see Use with your agent.

Tools

Core (always on)

The default invocation exposes these 13 tools — the full Python reference set plus git_push. They match the Python server's names, schemas, and error shapes one-to-one.

Tool	Description	Annotations
git_status	Working tree status	read-only
git_diff_unstaged	Unstaged changes	read-only
git_diff_staged	Staged changes	read-only
git_diff	Diff working tree against a branch/tag/commit	read-only
git_commit	Record staged changes	—
git_add	Stage files; ["."] stages everything	—
git_reset	Unstage all	destructive
git_log	Commit log with optional date filtering	read-only
git_create_branch	Create a branch	—
git_checkout	Switch branches	—
git_show	Show a commit	read-only
git_branch	List branches (local/remote/all, with contains/not_contains)	read-only
git_push (new in v0.1.0)	Push to a remote. SSH agent for git@, credential helper for https://	destructive

Optional groups (--features <LIST>)

Pass --features with a comma-separated list to enable additional groups, or --features all to enable everything. Without the flag, the core 13 above are the only tools exposed.

Group	Flag	Tools
Inspection	inspection	git_blame, git_blame_line, git_ls_tree, git_cat_file, git_show_ref
Tags	tags	git_tag_list, git_tag_create, git_tag_delete, git_tag_push, git_describe
Stash	stash	git_stash_list, git_stash_save, git_stash_pop, git_stash_apply, git_stash_drop, git_stash_show
Remotes / network	remotes	git_remote_list, git_remote_add, git_remote_remove, git_remote_set_url, git_fetch, git_remote_prune, git_ls_remote
History (mostly destructive)	history	git_revert, git_cherry_pick, git_reset_hard, git_clean, git_rev_parse
