GitHub's official MCP Server

GitHub Agentic Workflows

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

Give any AI agent the ability to code

AI agent security scanner. Detect vulnerabilities in agent configurations, MCP servers, and tool permissions. Available as CLI, GitHub Action, ECC plugin, and GitHub App integration. 🛡️

Agent skills synthesizing years of software engineering discipline into a prescriptive methodology for solo developers

Run Claude Code, Codex, and Gemini side by side — each in its own git worktree

Give your AI Agent a whole IDE, not just the files

mcp-language-server gives MCP enabled clients access semantic tools like get definition, references, rename, and diagnostics.

Evidence-grounded repository audit CLI - deterministic scanner, MCP server, live dashboard, and a GitHub Action that posts PR diffs.

The Simulink Agentic Toolkit gives your AI agent both the tools and the expertise to work effectively with Simulink and Model-Based Design.

Enterprise-grade (40m+ LOC) codebase intelligence, zero-setup, local & private Plugin/Skill/Extension or MCP: hybrid semantic search, polyglot dependency graphs, symbol-level impact analysis & call-flow, interactive HTML viewer, cross-project & branch-aware search, DB/API/infra knowledge. 61% less tokens, 84% fewer calls, 37x faster. Cloud in beta.
