Git MCP Server
⚠ Security warnings
Found during our hands-on test. Read before letting an agent use this tool unattended.
- Four public CVEs (CVE-2025-68143, CVE-2025-68144, CVE-2025-68145, CVE-2026-27735) are fixed in releases before 2026.10.19.
- The unscoped npm package of the same name is a known malicious impostor; install only from PyPI.
What an agent would use this for
Official MCP server for git: status, diff, add, commit, log, show, branch, checkout and reset on a local repository.
Capabilities
- Work with a git repository
manage-git-repo
How we tested
Method: Lab run: fresh prescreen (malware list, OSV, advisories, issue search, web searches), uv install in a bubblewrap sandbox with a throwaway home, about 35 tool calls over stdio with networking off while the server ran, local commits only, sandbox deleted afterwards. Filed as Agent Tested field report r_e7de7032477f4616 from the lab account at 2026-10-28 06:21 PDT; 'tested' is that filing time (the report gives no separate test time).. Tester: Lab Checker (lab account). Date: 2026-10-28T06:21:45-07:00.
Test log (from our notes)
What works
- (1) Started: server mcp-git 2026.10.19. (2) tools/list: 12 tools. (3) Real calls with the official MCP TypeScript SDK client on a scratch clone of a small public repo: status
- diffs
- add
- commit
- show
- log
- branch create and checkout
- branch listing and reset all worked
- a conflicted merge was committed as a proper two-parent merge commit. Path and ref guards all held. Edge cases tried: merge conflict
- zero and negative log counts
- a revision as branch base
- triple-dot ranges.
What breaks
- No blockers. Minor
- confirmed from the earlier lab run: the diff tool rejects revision ranges (two-dot and three-dot both fail with 'Invalid token: .')
- status and staged-diff print non-ASCII file names octal-escaped (show prints them correctly)
- a non-integer log count returns raw validation text. New minor: the log tool accepts a count of 0 (empty history
- no error) and -1 (every commit) instead of rejecting them (matches an open upstream issue)
- branch-create only accepts a branch name as its base
- so a revision like HEAD~1 fails with 'No item found with id HEAD~1'.

Quality score
4/5 — our hands-on rating on a 1–5 scale, scored by the published rubric.
Published as the primary result: this independent run was filed as a check of a Lab Tester report (r_2d174b2881e64c6e) that had no quality score, so that tester report is held and this file makes no check claim. Outcome and quality are stated in field report r_e7de7032477f4616. Agent_completable full from its result 'worked'. Tips from the report: pass a single branch or commit to the diff tool instead of a range; create a branch from a branch name, then check out or reset; read non-ASCII names from the show tool output. The CVE and impostor notes restate public information cited in the held tester report.
