GitHub's official CLI: manage pull requests, issues, releases and Actions workflows from the terminal. Most commands support --json output that agents can parse, and an official agent skill is available. Run gh auth login first.

GitHub's official MCP server: lets agents read and write repositories and code, manage issues and pull requests, and check Actions workflows and code-scanning alerts. Use the hosted remote server or run it locally in Docker; needs a personal access token or OAuth.

Connects GitHub's official remote MCP server to manage issues and PRs, review code, search repos and call the GitHub API from Claude Code. Requires GITHUB_PERSONAL_ACCESS_TOKEN.

Connects GitLab's official remote MCP server (beta) so Claude can work with repos, merge requests, CI/CD pipelines, issues and wikis on GitLab.com. MCP access must be enabled on the top-level group, with browser OAuth. In Anthropic's official plugin marketplace.

Detects hardcoded passwords, API keys and tokens in Git repos, files and stdin, and can run as a pre-commit hook or GitHub Action to block leaks. Now feature-frozen with security fixes only, as the author has moved on to Betterleaks.

Multi-language git hook manager: declare formatting, lint, secret scanning and other hooks in .pre-commit-config.yaml to run automatically before each commit, or have the agent self-check with pre-commit run --all-files before committing.

GitHub's official terminal coding agent, sharing its harness with the Copilot coding agent and shipping with the GitHub MCP built in. Work with repos, issues and PRs in natural language, approving each action before it runs. Requires a Copilot subscription.

Microsoft's official Azure DevOps MCP server: query and act on work items, repos, pull requests, build pipelines, test plans and wikis. Sign in with a Microsoft account that has access on first use; Microsoft recommends the no-install remote version instead.

Community-maintained GitLab MCP server: manage projects, merge requests, issues, pipelines, wikis and releases, with support for self-hosted instances and a read-only mode. Needs a GitLab personal access token or OAuth.

Manages stacked branches and dependent pull requests with the gh stack GitHub CLI extension: splits work into layered branches with one PR each, then handles push, submit, sync, rebase and merge, using flags that keep commands non-interactive for agents. Official GitHub skill.

Before tool calls run, blocks destructive Git and file commands (git reset --hard, rm -rf) and access to sensitive files like SSH keys and .env. Parses command semantics, so bash -c wrappers are caught too. Works with Claude Code, Codex and other coding CLIs; needs Node.js 18+.
