git-mcp

A Git MCP server that doesn't suck

Exposes the full Git workflow to any MCP-compatible AI agent — inspect, write, branch, remote, stash, rebase, LFS, git-flow, documentation lookup, and more. Designed to be safe by default, composable, and fast. Powered by simple-git.

Built for coding agents in tools like GitHub Copilot, Claude Code, Cursor, and OpenAI Codex, while remaining compatible with any MCP client that can call tools and resources.

Features

• 11 grouped tools with 60+ actions covering everyday Git workflows and advanced recovery operations
• Safety-first — destructive operations require explicit confirmation; force push and hook bypass are opt-in via server config
• GPG/SSH signing for commits and tags, with server-level auto-sign support
• Git LFS — track patterns, manage objects, install hooks, migrate history
• Git Flow — git-flow-next-style workflow support with preset init, overview, config CRUD, generalized topic actions, finish recovery, optional hook/filter parity, and classic feature/release/hotfix/support aliases, without requiring the external CLI
• Documentation lookup — search git-scm.com and fetch man pages directly from the LLM
• MCP Resources — URI-addressable read-only views of status, log, branches, and diff
• Bundled agent skill — skills/git-mcp-workflow/ documents MCP-first Git workflows, recovery, worktrees, releases, and advanced operations for AI agents and coding agents; installable via skills-npm and skill.sh
• Multi-repo — pass repo_path per-call or configure a server-level default
• Cross-platform — macOS, Linux, Windows (Git for Windows)

Tool Reference

Tools are grouped by domain. Each root tool takes an action parameter that selects the operation. Where an action is marked as default, omitting action will use it.

set_config	Write a Git config value
aliases	List all configured git aliases

Status (git_status)

Action	Description
status	(default) Working tree and branch status
diff	Unstaged, staged, or ref-to-ref diff
diff_main	Changes from branch divergence point vs main (or configurable base branch)

History (git_history)

Action	Description
log	(default) Commit log with filtering, pagination, revision ranges, and pathspecs
show	Inspect a single commit
blame	Line-by-line attribution for a file

reset	Reset HEAD with configurable mode (soft/mixed/hard)
nuke	Hard-reset the last commit — requires confirm=true

Branches (git_branches)

Action	Description
list	(default) Local and remote branch listing

Bundled Agent Skill

git-mcp ships a bundled agent skill at skills/git-mcp-workflow/ that teaches any skills-npm-compatible agent to use the MCP tool surface instead of running raw git CLI commands. The skill covers:

• Why LLMs must not use the Git CLI (quoting hazards, silent failures)
• Inspect-before-mutate workflow rules
• Safety order for undo and recovery operations
• Full registered tool surface with action reference
• Workflow playbooks: feature branch, rebase, recovery, worktree, backport, release tagging, Git Flow, merge
• Git concept explanations anchored to MCP tools

Installing the skill

If your agent supports skills-npm:

npm install @selfagency/git-mcp   # or pnpm/yarn
npx skills-npm

Or add to your project's package.json so it runs automatically:

{
  "scripts": {
    "prepare": "skills-npm"
  }
}

Then add to .gitignore:

skills/npm-*

Safety

• All mutating tools have destructiveHint: true in their MCP annotations
• git_commits action=reset mode=hard requires confirm=true
• git_commits action=nuke requires confirm=true
• Force push (--force) is disabled unless GIT_ALLOW_FORCE_PUSH=true; force_with_lease is always available
• Hook bypass (--no-verify) is disabled unless GIT_ALLOW_NO_VERIFY=true
• git_flow hook and filter execution is disabled unless GIT_ALLOW_FLOW_HOOKS=true
• Paths are validated against the repository root — traversal attempts are rejected
• Credentials and tokens are never included in responses
