RemNote API and MCP server

RemNote has no API for flashcards, due cards or your daily goal. Sign in to RemNote once in your own Cloud Browser, and your AI agent does the work there for you. The same tools work over MCP for agents and as a REST API for scripts.

How do I connect RemNote to Claude, ChatGPT or my code?

AI agents connect over MCP, scripts call the REST API. Both reach the same 12 tools with one API key.

For AI agents: MCP

Add Cotlet to your agent once. RemNote and every other app you connect show up as its tools.

  • Claude
  • ChatGPT
  • OpenClaw
  • Hermes
  • GrokBot
  • Cursor
  • n8n
  • Any MCP client

    Add Cotlet to your agent

    Claude Code
    claude mcp add --transport http cotlet \
  https://cotlet.dev/mcp/v1 \
  --header "Authorization: Bearer $COTLET_API_KEY"
    Cursor
    {
  "mcpServers": {

      "url": "https://cotlet.dev/mcp/v1",
      "headers": {
        "Authorization": "Bearer ${COTLET_API_KEY}"
      }
    }
  }
}
    Codex
    # ~/.codex/config.toml
[mcp_servers.cotlet]
url = "https://cotlet.dev/mcp/v1"
bearer_token_env_var = "COTLET_API_KEY"

    Paste the snippet for your client. The same server and key serve every app you connect, so you do this once.

For scripts: REST API

Every tool is an endpoint under /api/v1/remnote with its own method and path, such as POST /api/v1/remnote/daily-documents, with the same API key. Our open-source repo has ready scripts to start from.

REST API docs

What can the RemNote API and MCP server do?

12 tools on your own RemNote account. Agents call them as operations of the MCP tools remnote_read and remnote_write; scripts call each one at its own REST endpoint, with the same inputs and answers.

Questions

Does RemNote have an API?

RemNote has no public REST API (checked 17 Oct 2026). Developers extend the app with the plugin SDK, which runs inside RemNote. The official MCP server is built into the desktop app and runs only on your computer: the app must stay open, web clients such as chatgpt.com and claude.ai cannot connect, it sees one knowledge base at a time, and it cannot reach the flashcard queue.

How do I get access?

Sign up free, open RemNote under Integrations in the console and press Request access. Your free trial starts with your account, no card needed.

Is the MCP server different from the API?

No, only the way in. Cotlet builds each integration as a REST API and puts an MCP server on top, so both have the same 12 tools, the same inputs and answers, one API key and one price. AI agents such as Claude, ChatGPT or Cursor use MCP; scripts, cron jobs and HTTP steps in n8n, Make or Zapier use the REST API.

What is the Cloud Browser?

Your own Chrome that Cotlet runs for you in the EU, around the clock. You open it from the console, sign in to RemNote yourself and press Enable for agents. Your agent's calls go through it, from its IP with its cookies, so RemNote sees the browser you signed in with. Password saving is off and the profile is stored encrypted with AES-256-GCM.

Can my agent act without asking me?

Not on anything that reaches other people: update_note wait for your OK by default. You can switch that off per tool for scheduled runs.

Should I use a RemNote MCP server from GitHub instead?

Pick one if you want the code on your own computer and do not mind the upkeep: you install it, sign it in and fix it when RemNote changes. Pick Cotlet if you want it hosted and kept working for you.

Can I use it in n8n, Make or Zapier?

Yes. Add https://cotlet.dev/mcp/v1 in n8n's MCP Client node, or call the REST endpoints from an HTTP step in Make or Zapier.

Who runs Cotlet?

Cotlet is run by Take Group, a Polish software company working since 2019. Take Group runs about 3,200 websites on its own systems and has its own DevOps team for infrastructure security. We built and used integrations like this inside the company for years before opening them as Cotlet.

Is Cotlet affiliated with RemNote?

No. Cotlet is independent and not affiliated with RemNote.
