Unabyss
Unabyss is a personal context vault that keeps your work knowledge in one place and serves it to AI agents over MCP. Connect apps like Notion, Slack, Gmail, and GitHub once, and every compatible agent loads structured context about you before the conversation starts. It targets founders, developers, and GTM teams who switch between Claude, Cursor, ChatGPT, and other tools and do not want to reintroduce themselves each time.
The product treats context as infrastructure, not chat memory. It pulls from authoritative sources, auto-tags incoming data by topic, confidence, sensitivity, and source app, then retrieves only the slice relevant to the current question. A permission layer can exclude private information, company confidential items, or entire apps at retrieval time so blocked context never reaches the model.
Setup follows a short loop: connect your sources, generate an MCP token, and plug the agent. Unabyss claims structured context is ready in under 90 seconds after connecting sources, with 300,000+ items already synced across its user base. The same vault travels with you across MCP clients instead of staying locked inside one platform.

Unabyss connects to MCP-compatible clients including Claude, Claude Code, Cursor, Codex, OpenCode, VS Code, ChatGPT, Hermes, and OpenClaw. Perplexity support is listed as coming soon on the integrations page.

Unabyss supports LinkedIn, Notion, Slack, Gmail, GitHub, GitLab, Linear, Jira, Google Drive, Google Calendar, Obsidian, HubSpot, Fireflies, Fathom, tl;dv, and many others. New integrations ship regularly according to Unabyss.
How do I connect Unabyss to Claude or Cursor via MCP?
Generate an MCP token in Unabyss, then add the server in your client. For Claude Code, Unabyss documents: claude mcp add --transport http unabyss https://mcp.unabyss.com/. Cursor supports the same MCP server via Settings or a config file.
How is Unabyss different from AI memory in ChatGPT or Claude?
Platform memory is learned from past chats, stays inside one app, and starts empty. Unabyss extracts context from your actual sources, keeps it structured and user-owned, and delivers it to any MCP-compatible tool so you do not start from zero when you switch agents.
How quickly does Unabyss build my context vault?
Unabyss says it generates your structured context in under 90 seconds after you connect your sources. From there, connected MCP agents pull your context automatically on each session.
Does Unabyss require a credit card to sign up?
No. Unabyss does not require a card to start. You receive $25 in free credits on signup and only add payment when those credits are used up.
