Start creating amazing diagrams with AI! 🎨📊✨

An MCP server that equips your AI coding assistant with live, verified Android knowledge — so it builds from official sources, not from memory.

Access and analyze Overleaf projects and LaTeX files through Git integration.

Allows AI assistants to interact with the GitHub API for repository management, code collaboration, and other development tasks.

Self-hosted MCP server over your markdown notes: hybrid search and note reading with sourced answers. The same vault is also a website, so the agent's memory is readable, git-diffable markdown. Single Go binary + SQLite, MIT.

Secure MCP access to local repositories from ChatgptWeb without shell, Git, or arbitrary writes.

Creates commit messages from staged files in a local git repository.

Anchor is local repo and org memory for AI coding agents. It indexes GitHub PR history, current code, tests, regressions, architecture, and cross-repo impact locally, then exposes concise cited context through MCP and CLI workflows. Local-first. Read-only GitHub access. No CLI telemetry. No SaaS. No remote LLM calls.

An MCP server for interacting with the AtomGit API for version control and code hosting.

Design system MCP server — query tokens, components, icons, and WCAG contrast data from Git-backed design systems.
