CellMath is a governed AI memory and knowledge-cell MCP server designed to stop context bloat, unverified memory drift, and agent hallucinations. Instead of dumping raw, noisy RAG chunks into every turn, CellMath organizes persistent agent knowledge into structured, isolated Knowledge Cells with causal graph edges and strict write-time governance—keeping the full 3-tool MCP schema ultra-compact (~1,200 tokens). Core 3-Tool Pipeline: • vault_access — Read-only lookup, cell hydration, and graph edge traversal with strict zero-match silence (never fabricates context when no verified cell exists). • verify_safety — Preflight security and policy gate that blocks destructive or unsafe operations before execution. • vault_commit — Governed state mutation (store, update, causal edges, session checkpoints, and 4-tier purge) enforcing source provenance. Built for Claude, Cursor, ChatGPT, Gemini, and autonomous agents over Streamable HTTP.
A portable knowledge-graph memory you pass in and get back. No database. 4 of 6 free.
Wren is the AI handwriting notes app for iPad and Apple Pencil. This MCP server connects your AI assistant to your Wren notebook: ask for a graph, flowchart, formula, mind map, or a full study page, and it appears as real, editable ink in your notebook — synced to your iPad. With Wren connected, your AI can create handwritten notes with graphs, flowcharts, formulas, tables, bar charts, timelines, number lines, labelled diagrams, worked solutions and mind maps; add pages and multi-section study pages to existing notes; list and read your notes and notebooks; and look up your account profile. Your handwriting is yours: connected AI can only write on pages it created — it can never modify your own handwriting. Sign-in is Google OAuth; guest Wren accounts cannot be linked. Try: 'Graph y = x^2 - 4 in a new Wren note called Quadratics' · 'Make me a study page on photosynthesis' · 'Find my Wren notes with chemistry in the title'

XMemo is a user-owned Memory OS for AI agents, providing a shared, persistent memory layer across AI assistants, IDEs, CLIs, tools, projects, and sessions. It enables ChatGPT, Claude, Codex, Cursor, Gemini, and other supported AI clients to access authorized long-term context without requiring users to repeatedly explain their preferences, project decisions, or previous work. Beyond basic memory storage and retrieval, XMemo supports semantic search, contextual recall, memory updates and corrections, source attribution, version history, project-scoped context, task tracking, and governed memory lifecycle management. Identity-aware access controls, scoped authorization, and memory isolation help users manage which agents and workflows can access their information. XMemo also provides advanced capabilities for structured knowledge, reusable procedures, and memory consolidation through its broader Memory OS platform. Connect through hosted MCP with OAuth or bearer-token authentication, or integrate directly through REST APIs and supported client tools. Memory remains available across authorized clients and sessions, with user-controlled access, export, and deletion. Website: https://xmemo.dev Documentation: https://xmemo.dev/docs
Long-term memory shared by Claude Code, Cursor, Codex, Copilot and any MCP client: typed memories, hybrid vector + keyword search, a memory graph, contradiction detection, and task claims so several AI tools don't edit the same files. Hosted or self-hosted.

A2A Grocery — the agentic commerce hub for retail grocery, at its original address
The system of record for AI agents — open-source (MIT) database where agents and people share data.
CWI Discovery Engine is the sync-licensing discovery layer for AI agents: natural-language brief in, licensable tracks with verified ISRCs and one-signature clearance out. 29 MCP tools (find_tracks_for_brief leads). For general ISRC metadata lookup, we defer to MusicBrainz — we are the licensable-track discovery layer, not a general database.
Encrypted memory, knowledge graph and provable history for AI agents. ENYAL is the trust infrastructure for autonomous AI: identity, encrypted memory, and BSV-anchored proofs. Archived records are Merkle-batched and anchored to a permanent cryptographic ledger, and any record's inclusion proof can be checked by anyone, with no account.
Exact, shared memory for multiple AI agents. Azquo is a hierarchical database: each fact is stored once in hierarchies that always total correctly, every write is attributed to the agent and person behind it, and any figure can be traced back to the file and cell it came from. There is no schema to design first - agents build and reorganise the structure themselves - and people work with the same data live in Microsoft Excel. Suited to finance and insurance work, where figures must stand up to review.
Claimora expands AI agents' research horizons through an interconnected graph of scientific claims, evidence, contradictions, and cross-disciplinary relationships. Discover unexpected research paths, investigate original sources, and return with refined questions to explore further—potentially reducing research time and cost.
Neutral verification registry for femtech (women's health) information sources. It indexes sources by provenance, authority tier, jurisdiction, and machine-readable compensation disclosure. No diagnosis, no efficacy claims, no referral fees.
Lets your assistant search and read your ThinkerNotes: the insights you've written in your own words, your drafts, and your notes on books and podcasts. Ask "what have I already figured out about pricing?" and get back your own conclusions instead of a generic answer. Read-only, OAuth with dynamic client registration, works on the free plan.
Your Recipes, Beautifully Kept. weReci MCP server lets Claude and other MCP clients work with your personal weReci cookbook, the recipes you've imported from the web, social video and scanned family books. Interactive UI in the chat. weReci supports MCP Apps, so in clients that support it, tools return live views instead of plain text: recipe cards, shopping lists and your recipe graph. Clients without MCP Apps support get the same results as text. Find and read recipes: search your collection in plain language, open any recipe in full, or get an overview of what's in your cookbook. Cook with them: scale a recipe to any serving count, with cooking adjustments as well as amounts. Get substitution suggestions with ratios and caveats. Explore connections: browse your recipe graph (shared ingredients, techniques and cuisines), trace the connection between two recipes, and look up where a dish sits on the cuisine map. Themed collections: list the themed groups weReci curates from your cookbook, or ask it to reshuffle them. Shop: build a shopping list from one or more recipes, add or update items, and read the list back. Share: email a recipe to someone. Longer jobs like conceit reshuffles run in the background, with tools to check their progress. Everything is scoped to your own cookbook, or to a shared one you've joined.
Give AI assistants secure access to your organization's structured business data. Search records, create and update records, retrieve schema information, and manage workflow states using natural language. You need two values for every request: x-api-key — your Web Data Forms API Key x-group-id — your Web Data Forms Group ID You can find these in your Web Data Forms accounts group->information page. Preferred method: request header When possible, pass the credentials as HTTP headers: x-api-key: <your-api-key> x-group-id: <your-group-id> This is the preferred option because it keeps credentials out of the URL and is more secure. Fallback method: query parameters If your MCP client does not support custom headers, the server also accepts the credentials as URL query parameters. Example: https://mcp.webdataforms.com?x-api-key=abc123&x-group-id=xyz456 Detailed information here: https://github.com/Web-Data-Forms/mcp-server-docs/blob/main/README.md
Zero-Ops deploy of a private AI coding workspace onto your own VPS — straight from your AI chat. Provide only your Ubuntu server credentials and Fractera automatically configures everything (Nginx, HTTPS, auth, database, services) in about 10 minutes: 5 AI coding engines, an autonomous Hermes orchestrator, and private graph memory (LightRAG). No terminal, no DevOps. IP-first and free; a custom domain with HTTPS is an optional later step.
Stop juggling chat windows. Complete your project in one seamless conversation. Marvnor is a proprietary, hosted MCP/API service that gives your AI agent persistent project memory. Your agent saves confirmed or evidence-backed requirements, decisions, and changes. For each new question, Marvnor retrieves relevant saved records, verifies claims against them, and flags conflicting information for your confirmation. Records can be corrected or deleted as your project evolves. Spend less time repeating the background and untangling old decisions. Pass only the current question and relevant results to your model to reduce repeated history in its input and keep your project moving.

Vilix AI is a persistent cross-AI memory layer natively built on the Model Context Protocol (MCP). Connect once, and your memory, projects, decisions, preferences, and conversation history will follow you across all your favorite, and any other MCP-compatible AI tools: ChatGPT, Claude, Cursor, Codex, Grok, Perplexity, and more. While memory tools solve the problem of switching between apps, Vilix AI also solves the problem of switching between devices: continue your conversation on your phone, then pick it right back up on your laptop minutes later, with full context. Stores actual conversations, not just extracted facts, and has been engineered for long-term storage with years of context rather than days. Exposes get_context (what to say based on relevant memory to recall) and save_turn (what to persist) as core MCP tools, and full project, task, and skill management for agents to track what work is being done. Use cases include ChatGPT memory, Claude memory, Cursor memory, and AI agent memory in a shared layer for founders and developers who are using multiple AI tools and tired of having to re-contextualize everything every single time. OAuth-based setup with no tokens required, including a free tier. See https://vilix.ai/get-started for more information.
