Kybase MCP Server

Your AI forgets when the session ends. Kybase remembers. Kybase gives Claude, Cursor, Windsurf and any other MCP-speaking agent a long-term memory you own: one Markdown knowledge base, running on your own machine, that every agent can search, read and update - and that you can open in a browser and edit by hand. It runs locally over stdio via the published package.

People who work with agent memory, knowledge base and nextjs and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

01 · Install Kybase

Claude Code

claude mcp add kyrzin-kybase -- npx -y kybase-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "kyrzin-kybase": {
      "command": "npx",
      "args": [
        "-y",
        "kybase-mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

What is Kybase?

Your AI forgets when the session ends. Kybase remembers. Kybase gives Claude, Cursor, Windsurf and any other MCP-speaking agent a long-term memory you own: one Markdown knowledge base, running on your own machine, that every agent can search, read and update - and that you can open in a browser and edit by hand. It runs locally over stdio via the published package.

Is Kybase still maintained?

Yes - as of 2026-09-30, its last commit was 2026-09-23 and it shipped 6 releases in the last 90 days. We re-verify nightly.

How do I install Kybase?
