Add-ons & integrations

Graphify

Turns your code folder into a searchable knowledge graph — via local Tree-sitter parsing (~40 languages), with no LLM calls and no vector embeddings.

Integrates directly into Claude Code (a CLAUDE.md directive plus a hook that consults the graph before every file search), ships its own MCP server, and also supports Codex, Cursor, Copilot & co. Can also export the graph as an Obsidian vault. Users report up to 70x fewer tokens on large codebases (community claim).

Official MCP Server Catalog

The official reference repo for Model Context Protocol servers — the starting point for almost every MCP setup.

Anyone who wants to give their agent new capabilities (databases, APIs, file systems …) will find the reference implementations here. The protocol is now being developed further under the Linux Foundation.

→ DetailsGitHub: modelcontextprotocol/servers ↗

claude-flow (ruflo)

Multi-agent orchestration for Claude Code, Codex & co: swarms, adaptive memory, RAG integration.

One of the most widely used frameworks once a single agent isn't enough — for autonomous multi-agent workflows. The npm package is still called claude-flow, while the GitHub repo was renamed to ruflo.

Context7

MCP server that loads current, version-accurate library documentation directly into your agent's context.

The antidote to stale training knowledge: instead of hallucinating API calls, the agent reads the actual docs for your library version. Considered a must-have MCP server in many 2026 rankings.

→ DetailsGitHub: upstash/context7 ↗

Playwright MCP

Microsoft's official MCP server for browser automation — via the accessibility tree, without screenshots or a vision model.

The standard choice when your agent needs to operate websites or end-to-end test your own frontend.

→ DetailsGitHub: microsoft/playwright-mcp ↗

GitHub MCP Server

MCP server maintained by GitHub itself for repos, pull requests, issues, code search, and CI/CD insights — remote or local, with OAuth login.

Official vendor support for the full GitHub API — near the top of virtually every "best MCP servers" ranking in 2026.

→ DetailsGitHub: github/github-mcp-server ↗

Claude Code for VS Code

Anthropic's official IDE extension: a sidebar panel with inline diffs — Claude Code visually inside VS Code instead of just in the terminal.

The official option for anyone who prefers working in the IDE over the terminal; per the vendor, over 20 million installs (as of 13.07.2026, Marketplace).

→ DetailsVS Code Marketplace: Claude Code ↗

Claude in Chrome

Anthropic's official browser extension: Claude reads, clicks, and navigates web pages alongside you — available to all paid plans since December 2025.

Closes the build-test-verify loop: Claude Code builds, the Chrome extension checks the result live in the browser.

Obsidian Local REST API

Community plugin that starts a local HTTPS server inside Obsidian — since 2026 with a built-in MCP endpoint: read/write notes, search the vault.

The de facto standard way to connect Claude Code or Claude Desktop to your Obsidian vault — a separate MCP server is no longer needed. (Not an official Obsidian product.)

→ DetailsGitHub: coddingtonbear/obsidian-local-rest-api ↗

Copilot for Obsidian

Chat assistant right inside the vault: ask questions about your own notes, draft text — with selectable models, including Claude Opus 4.7.

The most popular AI plugin for Obsidian. The frontend is open source; the Plus features are paid (Brevilabs, not affiliated with Obsidian or Anthropic).

→ DetailsGitHub: logancyang/obsidian-copilot ↗

Smart Connections

Semantic search across your own notes via a local embedding model — no API key needed — plus AI chat over the vault.

Surfaces notes that are related in content but missed by plain linking; runs entirely locally and is often used alongside Claude Code setups.

→ DetailsGitHub: brianpetro/obsidian-smart-connections ↗

Graph Context for Claude Code

Young Obsidian plugin that plugs the vault into Claude Code's /ide selection: selecting text automatically sends along graph context (resolved links, backlinks, heading path).

Uses the same mechanism as the official IDE extensions — interesting for anyone using notes as a knowledge base for coding. Still very new (June 2026).

Superpowers

A skills framework plus a complete development methodology for coding agents: the agent plans first, writes tests first (TDD) and works through tasks via subagents — the right skills trigger automatically.

One of the most-starred coding-agent projects on GitHub (~260k ⭐, since October 2025), by Jesse Vincent (obra). Works with Claude Code, Codex, Cursor, Antigravity, GitHub Copilot CLI and more, and installs as a plugin from Anthropic’s official marketplace. Open source (MIT).

→ DetailsGitHub: obra/superpowers ↗

Serena

An MCP toolkit that gives your agent IDE-like, semantic code tools — symbol-precise finding, editing and refactoring via language servers (LSP) instead of blind text grep.

"The IDE for your agent": it works at the symbol level (functions, classes, references) rather than line by line. That saves tokens on large codebases and works with any MCP client (Claude Code, Codex, Cursor …). Open source (MIT).

→ DetailsGitHub: oraios/serena ↗

Cline

An open-source, autonomous coding agent — as a VS Code extension, CLI and SDK. It runs commands directly in your terminal, watches the output live and reacts to errors.

One of the most popular open-source options for agentic coding in the IDE (Apache-2.0). Bring-your-own-key (Anthropic, OpenAI, local models …), a separate plan/act mode and MCP support. Formerly known as "Claude Dev".

→ DetailsGitHub: cline/cline ↗

Repomix

Packs your entire repository into a single, AI-friendly file — ideal for handing an LLM or chat model the whole codebase at once.

Handy when you want to paste code into ChatGPT, Claude, Gemini & co. outside an agent. It counts tokens, respects .gitignore, can compress and check for secrets. Runs without installation via npx and also as a web tool (repomix.com). Open source (MIT).
