Best Graph AI Skills & MCP Servers

Shared, persistent memory for AI assistants, built on the Zettelkasten method.

Structured fact memory MCP server — SQLite + FTS5, trust scoring, entity graph, bilingual retrieval for Claude Code & Codex

AI-powered video generation engine. MCP server and SDK for creating motion graphics from prompts.

MCP server + CLI for the Unified Product Graph — drop into Claude Code or use the `upg` command.

Local-first code intelligence CLI for unerr

OpenCodeHub — stdio MCP server exposing code-graph + group tools

Persistent memory for AI coding agents. Knowledge graph with 4-tier taxonomy, confidence scoring, and MCP protocol support for Claude Code, Cursor, Gemini CLI, Windsurf, Cline, Codex, and OpenCode.

Repository scanner that builds a structural map of a codebase (functions, imports, exports, dependencies) and adds file descriptions of what the file does,, so anagentic AI can just read the map and know the project context

DEPRECATED — install the Claude Code plugin at gramatr/claude-plugin instead. This npm package no longer ships a CLI; Codex and Gemini integrations are paused pending HTTPS+OAuth MCP support.

Complete codebase intelligence — loads treesitter, symbol, outline, callgraph, depgraph, refs.

Codebase graph analysis for AI agents — AST + call graph + type graph + hybrid semantic search via MCP

Dependency graph analysis — imports, exports, circular deps, fan-in/out.

Code intelligence MCP server. Indexes your repository into a queryable call graph for AI coding agents.

Knowledge base — loads knowledge, fts, graphbuild, graphquery for document indexing and graph-powered search.

MCP server for the LaunchNotes API

MCP server for AI agents — project graph, code quality analysis, visual web explorer. JS, TS, Python, Go.

The Application Engine for the AI Era. A multi-threaded, AI-native runtime with a persistent Scene Graph, enabling AI agents to introspect and mutate the living application structure in real-time.

A local context graph for AI coding agents.

Repo memory for coding agents. Local-first MCP for Claude Code, Cursor, Windsurf, and Codex CLI: symbol graph, blast radius, diff-aware review, and git-pinned decisions. MIT; no API keys or code upload.

MCP proxy for Pharaoh — maps codebases into queryable knowledge graphs for AI agents. Enables Claude Code in headless environments (VPS, SSH, CI) via device flow auth.

AI codebase indexer and MCP server for Claude Code, Cursor, and Copilot. Pre-index your project into a compact graph and measure real token savings with `larkx bench`.

Agent-first MCP server: AI coding agents find, compare, verify, and stack-build the right open-source tools across 35+ registries (npm, PyPI, Cargo, Maven, Go, RubyGems, NuGet, Hex, Composer, and more). Graph-aware ranking + version-aware compatibility in

Call graph analysis — callers, callees, call chains.

Information-geometric agent memory with mathematical guarantees. 4-channel retrieval, Fisher-Rao similarity, zero-LLM mode, EU AI Act compliant. Works with Claude, Cursor, Windsurf, and 17+ AI tools.
