GitHub's official MCP Server

GitHub Agentic Workflows

A framework-agnostic, git-native standard for defining AI agents

Agent-managed GitHub merge queue for Codex, Claude Code, Cursor, and MCP clients

Give any AI agent the ability to code

Mention any ACP coding agent from Slack, GitHub, GitLab, Linear, or Lark. OpenTag runs Claude Code, Codex, Cursor and more on your own machine, then replies in-thread with verified, evidence-backed results.

Turns issues into merged PRs/MRs with zero human intervention — supports GitHub and GitLab, and Claude Code, Codex CLI, Kiro CLI, Antigravitiy CLI, opencode, and other agent CLIs.
