MCP server directory

A Model Context Protocol (MCP) server that implements the Zettelkasten knowledge management methodology, allowing you to create, link, and search atomic notes through Claude and other MCP-compatible clients.

Read and write Apple Notes with bidirectional Markdown conversion. Fast SQLite queries for listing/searching, AppleScript + native import for full CRUD. Supports stdio and Streamable HTTP transports.

Persistent AI memory brain for Claude Code, Cursor, Copilot, Windsurf, Cline & Zed. `session_start()` briefs your AI on last session, lessons, and open tasks in one call. 84 tools — Team Brain, semantic BM25+ search, Team Telepathy, Ambient Git Learning, Memory Crystals, Analytics, and managed Valkey/Redis. `npx @cachly-dev/init` — free tier, no credit card. [Website](https://cachly.dev)

Intelligent agent memory with semantic recall, automatic consolidation, contradiction detection, and bi-temporal knowledge graph. 80% on LOCOMO benchmark using 96% fewer tokens than full-context approaches.

Persistent, local-first AI memory: a semantic knowledge graph of plain Markdown files that humans and LLMs both read and write. Works with any MCP client, with optional cloud sync and team workspaces.

Hosted agent memory that keeps an audit trail. Three tools — `commit_mem`, `recall`, `status` — where each write carries provenance (which run, tool, or operator produced it), contradictions with prior state surface as inspectable changes rather than silent overwrites, and a bad run is recovered from a snapshot instead of repaired by hand. `pip install -U bilinc`

MCP for the [Sovereign AI Blog](https://sovgrid.org), a hands-on engineering log of self-hosted AI on NVIDIA DGX Spark (GB10/SM121A). 44+ articles covering SGLang, Mistral, Voxtral, OpenClaw. Three tools: full-text search, article retrieval, and SGLang config validator for GB10 hardware. Free, no auth, no client-side tracking. `https://mcp.sovgrid.org/self-hosted-ai?ref=awesome-mcp`

Retrieve context from your [Ragie](https://www.ragie.ai) (RAG) knowledge base connected to integrations like Google Drive, Notion, JIRA and more.

Hierarchical memory engine for AI agents with automatic decay, promotion, semantic dedup, and self-organizing topic tree. Single Rust binary, zero external dependencies.

Shared context engine for devs and teams. Syncs GitHub, Notion, and saved decisions into reusable project context, so Claude, ChatGPT, Cursor, VS Code and Gemini start each session with the architecture and decisions the team already made. OAuth 2.1 PKCE, AES-256 encrypted, RFC 9728 compliant. `https://mcp.memxus.com/mcp`
