Jade Note

Jade Note is a Markdown note app with a hosted MCP server at its core. Connect Claude or ChatGPT over OAuth and your notes become persistent memory the AI can search, write, link, and version, with previews and rollback to keep autonomous edits safe.

Jade Note is a notes application built around an MCP server rather than treating MCP as an add-on. The premise is simple: language models forget everything when a session closes, so the notes you keep need to become the memory your AI reads and writes. A hosted MCP server with OAuth 2.0 exposes 26 tools that let capable agents such as Claude and ChatGPT search, create, edit, link, and version notes directly. Nothing needs to be self-hosted, and you connect a URL instead of maintaining a bridge script against a local app. The product works on two levels at once. Day to day it is an ordinary Markdown note app with categories, semantic search, typed links, and custom properties. The same store is what your AI touches over MCP, so a journal entry you type in the morning can be cited in a chat answer that afternoon, and conclusions the AI draws can be written back as new notes. Five relation types (related, parent, child, continues, references) turn a flat pile of text into a graph, and category wikis hold standing context for the agent to reference. Safety is the part that matters for autonomous writes. Every change carries a preview, automatic versioning, rollback, and optional per-note write protection. Notes created through MCP are tagged so you can see provenance, OAuth issues a separate token per client, and per-category permissions scope what each agent can reach. Scheduled and event triggers let AI review memory while you are away, and the Catch up feature checks freshness, conflicts, and link health on paid plans. AI credits meter that processing, with features pausing until the monthly reset once credits run out. It suits people who already use Claude or an MCP-capable client daily and want continuity across conversations: personal context, project decision trails, research notes, habit logs, or a small team knowledge base. The obvious comparison is pasting context into each chat or running a local MCP bridge over an existing notes app. Jade Note wins on convenience and write safety, but it is a young product with a single memory store to migrate into and an AI credit ceiling.
