Remnus

Open-source MCP-native workspace for humans and AI agents.

Kanban boards, databases, and pages that Claude, Cursor, and any AI agent can read and write via MCP — alongside you.

What is Remnus?

Remnus is the Human-Agent Collaborative Workspace, built around the Model Context Protocol (MCP). Every page, database, and kanban board in your workspace is accessible to AI agents via a first-class MCP server — connect editors with one-click OAuth 2.1 (PKCE), or use a scoped bearer token for headless / CI agents.

Unlike Notion's MCP integration, Remnus is designed for headless, CI/CD, and coding agent workflows from day one.

OKF-native context, not a workspace dump

Remnus uses Open Knowledge Format (OKF) ideas as a portable knowledge contract. Pages can carry descriptions, types, tags, sources, lifecycle state, freshness dates, and revision-bound review signals. OKF v0.2 import/export is the interchange layer; the editable Remnus workspace remains canonical.

The prepare_context MCP tool turns a concrete task into Context Pack v2: a token-budgeted set of concepts ranked by BM25 relevance, native metadata, page links, freshness, and trust. Smart mode advertises this context-first flow automatically for meaningful work. Strict mode additionally requires the same agent's short-lived contextRunId before Remnus MCP mutations.

This does not let an MCP server control local files, shell commands, or Git. Repository-level enforcement uses the supplied AGENTS.md and CLAUDE.md snippets. Read the public Context-First MCP guide and the implementation story, How Remnus Uses OKF to Give AI Agents Better Context.

Features

• Pages — Markdown editor with slash commands, nested sub-pages, and icons
• Databases — Customizable columns, Table / Kanban / Calendar views, filters, sorts
• Dashboards — Live status screens (metrics, charts, lists, embedded views) that an agent builds from a few hundred tokens of JSON and a human can edit block by block
• MCP Server — 27 tools + 7 resources + 7 prompts over stateless Streamable HTTP
• OKF-native context — Portable knowledge metadata, exact-revision reviews, Context Pack v2, and Smart/Strict MCP policies
• Agent auth — One-click OAuth 2.1 + PKCE (RFC 7591 dynamic registration) for editors, or scoped read/write personal access tokens for headless agents
• Multi-workspace — Invite members, role-based access (owner / member / viewer)
• Desktop app — Tauri v2 shell for Windows, macOS, Linux
• Mobile — Capacitor v8 for iOS and Android (loads remnus.com)
• i18n — English, Türkçe, हिन्दी, Español, Français, Deutsch, 中文, Русский

Quick Start — Self-host

Local Development

git clone https://github.com/Ranork/remnus-app.git
cd remnus-app
cp .env.example .env          # fill in AUTH_SECRET + OAuth credentials
npm install
npm run db:migrate
npm run dev

Open http://localhost:3000. The first user to sign up is auto-promoted to admin.

Docker Compose (5-minute setup)

If you prefer to run Remnus using Docker:

1. Clone the repository and navigate into it:

   git clone https://github.com/Ranork/remnus-app.git
   cd remnus-app
   

2. Copy the environment template and fill in the required variables (especially AUTH_SECRET and OAuth credentials):

   cp .env.example .env
   

3. Start the application:

   docker compose up -d
   

4. Access Remnus at http://localhost:3000. The SQLite database will be persisted automatically using a Docker volume.

Deploy

Add MCP to your editor

After signing in, open the AI Agents panel from the sidebar and click Connect editor. It walks you through every supported editor (Cursor, VS Code, Claude Code, Codex, Windsurf, and more).

Install from a registry

Remnus is published on the official MCP Registry (io.github.Ranork/remnus) and on Smithery, so MCP-aware clients and directories can discover it automatically. Smithery offers one-click install across many clients (Claude, Cursor, VS Code, Codex, Windsurf, and more) — open the Smithery page and click Add to toolbox, or use the Smithery CLI to install straight into a client's config:

npx -y smithery@latest mcp add ranorkk/remnus --client claude

Swap --client for cursor, vscode, codex, windsurf, etc. Either way, the first connection runs the same OAuth 2.1 sign-in — no token to paste.

Recommended — OAuth (token-less): point your editor at the MCP URL and approve the consent screen on first connect. Your editor runs the OAuth 2.1 flow automatically — nothing to copy.

Headless / CI — personal access token: create a scoped token from the AI Agents panel and send it as a bearer header.
