MemoStem MCP server

MemoStem across AI conversations

Your reviewed knowledge, across AI conversations.

Let a connected AI reuse your private, confirmed knowledge or notice knowledge worth keeping as the conversation unfolds. New material becomes a private draft only after you confirm—without uploading the whole conversation or publishing anything automatically.

This public repository is the official distribution source for MemoStem's chat-host skills, plugin packages, and hosted remote MCP connection metadata. ChatGPT, Claude, Kimi, Gemini and Grok are the primary channels; Codex and Claude Code are compatible secondary channels. The MemoStem application and server implementation remain private. Distributable manifests, skills, examples, and documentation have no mirrored authoring copy in that private repository.

Save here, reuse in another AI conversation

Select an explanation in ChatGPT, save it as a private pending draft, and review and approve it in MemoStem. Then ask Claude or another connected host to find that knowledge. Sign in to the same MemoStem account in each host; no host gets access to another host's conversation history.

Only the specific suggestion you confirm is sent, never a transcript or hidden history.

In an MCP Apps-capable host with a connected account, check candidates and click Add. That click creates only the selected private pending drafts; no second chat confirmation is needed. If the host shows a text list instead, reply with the candidates to keep. Then open Candidate Inbox to read, edit, and approve them. Previewing or adding drafts does not approve knowledge or enroll it in practice. The picker UI is served by the hosted MCP server; see the MCP Apps contract and host requirements.
