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'

Governed organizational memory for AI, by EigenAtom. ChatGPT, Claude, Cursor and other agents save explicit memories to one shared store over MCP; AI only suggests labels, and the organization's deterministic policy decides who may read each memory, so recall returns only what the signed-in person may see. No admin bypass, audited changes, and memory content never reaches logs. Free 60-day trial, no credit card.
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

Discover MCP servers and packages, inspect their documented capabilities, endpoints, authentication requirements, provenance and observed readiness, and retrieve cited reference passages with document versions. Koskamo provides public discovery and reference tools alongside separately authorized contributor and owner workflows for server registration, listing maintenance, keys, issue reports and operation receipts. Tool discovery does not grant write authority: protected actions require the applicable account or owner key and documented confirmation. Live protocol observations and directory records are evidence of what was observed, not a guarantee that every connected service or tool works without its own credentials. Returned reference passages and third-party descriptions remain source material to review before citing or acting. Official connector repository: https://github.com/empline/koskamo-mcp. Support: support@koskamo.com.
A living map of all your work that keeps you, your team, and your agents on the same page
Liliphant joins your meetings and remembers the work across all of them. Most tools stop at one transcript. Liliphant connects every conversation, so you can ask what was decided, who promised what, what changed since the first meeting, or what's still blocked. Every answer comes with the exact quote, the speaker and the meeting it came from, and if something is unclear, Liliphant tells you. Open promises and unanswered questions stay in view until someone marks them done.
Shared workspace for Claude, ChatGPT and local models: notes, append-only logs, issues, recurring tasks and environment secrets, so what one AI did yesterday another can read today. Hosted service, free up to 1 GB per account; connect with an MCP-type API key (Authorization: Bearer or x-api-key).

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.
Second brain for investing. Understand what you own, compare changes against your own investment plan, and keep the reasoning behind your decisions. Start with holdings you supply in the conversation. Analyze allocation, fund look-through, overlap, concentration and fund costs, or replay a historical crisis over the submitted mix. These two tools need no Investboard sign-in and read or save nothing in an account. Missing reference data stays partial or unresolved; a historical replay is not a forecast. With your authorized Investboard account: - Read your mandate, holdings, exposures and historical correlations. - Explain whole-portfolio performance, separating contributions from investment result. - Compare keeping your portfolio unchanged, using new money to buy underweighted holdings, investing only part of a contribution, and alternatives involving sales. Rebalance previews save no check or plan. - Read what changed since your last approved review and prepare your stated reasoning for approval in Investboard. Preparing a review does not approve or complete it. - Run historical stress tests and revisit recorded investment decisions, theses and journal entries. - Stage holdings for an import you must confirm in Investboard. Try asking: - Here are my holdings and weights. What do my funds own underneath, and where do they overlap? - I can add 400 EUR and prefer buying underweighted holdings before selling. Compare the alternatives under my mandate. - What changed since my last review, and what still needs my attention? Account features require the relevant permissions, enabled sharing and applicable plan. Requested checks and stated decisions are saved. Account stress tests create history records; imports and prepared reviews need your action in Investboard. The tools do not place orders, transfer money or change your mandate. You make every investment decision. The four companion skills, Investment Strategy Check, Investment Decision-Making, Investment Thesis and Portfolio Intelligence, also work with supplied files. Install them separately from https://investboard.com/product/ai-toolkit#install. Your assistant provider's account requirements and usage limits apply.
