Knowledge Graphs

Outlook Assistant — MCP server with 22 tools for email, calendar, contacts, and settings via Microsoft Graph API

Map text into knowledge graphs to create a structured representation of conceptual relations and t…

Auditable AST code intelligence for AI agents: 18 task-oriented commands through one MCP tool, CLI, or agent skill. Supports JS/TS, Python, Go, Rust, Java, C, C++, C#, and HTML.

Find test gaps, generate grounded tests, and dynamically prove behavior with mutation testing.

Code Graph MCP Server

MCP server giving AI agents (Claude Code, Claude Desktop, Cursor, ChatGPT, Codex, OpenClaw) persistent long-term memory backed by your local Obsidian markdown vault. Hybrid retrieval (BM25 + ML embeddings + BGE reranker, RRF-fused), HNSW + int8 quantizati

Graph context, semantic search, guarded edits, and reviewable Git for local Obsidian vaults.

Search, extend, and act on your team's Naumu knowledge graph: notes, threads, and nodes.

npx memvara — connect a stdio MCP client to memvara, bitemporal memory for AI agents. Zero config: no URL to paste, and no browser at all when you already have a key.

Prism Coder — Local LLM fleet + MCP cognitive memory for AI agents. Wraps prism-mcp-server with the prism-coder brand CLI. Install once, run anywhere.

YATS — Yet Another Token Saver. One-command MCP server that indexes your codebase into a knowledge graph so AI agents (Claude, Cursor, Copilot) can search and navigate it without burning tokens.

RepoSkein gives your AI coding agent a map of your codebase — so it navigates structure instead of grepping and guessing.

Co-Engram adapter for Claude Code (MCP server).

A live layered dependency map for bottom-up development — MCP server + terminal pane. Ghost the design first, then light nodes up from the bottom as they are built and verified.

It just remembers.

Memory Palace MCP server for AI agents

Local-first context engine for AI coding agents. Pre-indexes your codebase into a dependency graph and feeds any MCP agent only the code that matters — 87% fewer tokens per call. New in 2.5: mechanical work verification and a PII/secret scanner. Works wit

Governed graph substrate for coding agents (Claude Code, OpenCode, any MCP-stdio host) — Apply-Gate + on-disk Kuzu store + MCP tools

A screen ↔ endpoint ↔ field dependency map: answers which screens break if you change an endpoint or a response field. Local-first, git-friendly, open source.

Local-first code graph: index a repo into an import/symbol graph and retrieve the relevant slice instead of whole files. Ships as a CLI, an MCP server for AI agents, a TypeScript API, and a VS Code chat participant.
