reMarkable MCP Server

Unlock the full potential of your reMarkable tablet as a second brain for AI assistants. This MCP server lets Claude, VS Code Copilot, and other AI tools read, search, and traverse your entire reMarkable library — including handwritten notes via OCR.

Why remarkable-mcp?

Your reMarkable tablet is a powerful tool for thinking, note-taking, and research. But that knowledge stays trapped on the device. This MCP server changes that:

• Full library access — Browse folders, search documents, read any file

• Typed text extraction — Native support for Type Folio and typed annotations

• Handwriting OCR — Convert handwritten notes to searchable text

• PDF & EPUB support — Extract text from documents, plus your annotations

• Robust page rendering — Renders pages locally and automatically falls back to a source PDF when the local stroke renderer can't (USB/SSH use the tablet's own PDF export; cloud uses the original source PDF), so images work across firmware versions and even without system graphics libraries installed

• Smart search — Find content across your entire library

• Second brain integration — Use with Obsidian, note-taking apps, or any AI workflow

Whether you're researching, writing, or developing ideas, remarkable-mcp lets you leverage everything on your reMarkable through AI.

Quick Install

🔌 USB Web Interface (Recommended)

Connect via USB and enable the web interface in your tablet's Storage Settings.

Setup:

1. Connect your reMarkable via USB

2. On your tablet: Settings → Storage → Enable "USB web interface"

3. Install via the button above

Why USB Web?

• ✅ Fast offline access over USB

• ✅ No subscription required

• ✅ Simple — just enable in Storage Settings

Add to .vscode/mcp.json:

{
  "servers": {
    "remarkable": {
      "command": "uvx",
      "args": ["remarkable-mcp", "--usb"],
      "env": {
        "GOOGLE_VISION_API_KEY": "your-api-key"
      }
    }
  }
}

Troubleshooting:

• Make sure your reMarkable is connected via USB and unlocked

• Verify USB web interface is enabled in Settings → Storage

• The tablet should be accessible at http://10.11.99.1

⚡ SSH Mode (Advanced)

For power users who need direct filesystem access. Faster than USB Web but requires developer mode (factory reset).

Requirements: Developer mode enabled + USB connection to your reMarkable

Add to .vscode/mcp.json:

{
  "servers": {
    "remarkable": {
      "command": "uvx",
      "args": ["remarkable-mcp", "--ssh"],
      "env": {
        "GOOGLE_VISION_API_KEY": "your-api-key"
      }
    }
  }
}

See SSH Setup Guide for detailed instructions.

☁️ Cloud Mode (Wireless)

Wireless access with no device connection required — your reMarkable syncs to the cloud and the MCP reads from there, so it works from anywhere. Requires a reMarkable Connect subscription.

Cloud mode fetches your whole library in parallel and caches content-addressed blobs on disk, so after the first run startups and document reads are near-instant (a 388-document library lists in ~4s cold, ~0.5s warm). See Cloud Performance & Caching to tune it.

1. Get a One-Time Code

Go to my.remarkable.com/device/desktop/connect and generate a code.

2. Convert to Token

uvx remarkable-mcp --register YOUR_CODE

3. Install

Or configure manually in .vscode/mcp.json:

{
  "inputs": [
    {
      "type": "promptString",
      "id": "remarkable-token",
      "description": "reMarkable API Token",
      "password": true
    },
    {
      "type": "promptString",
      "id": "google-vision-key",
      "description": "Google Vision API Key",
      "password": true
    }
  ],
  "servers": {
    "remarkable": {
      "command": "uvx",
      "args": ["remarkable-mcp"],
      "env": {
        "REMARKABLE_TOKEN": "${input:remarkable-token}",
        "GOOGLE_VISION_API_KEY": "${input:google-vision-key}"
      }
    }
  }
}

Connection Modes

All three modes share the same read, render, and upload tools. Cloud and SSH additionally support full library management — create folders, move, rename, and delete (all enabled by default) — so capability is near-identical and you can genuinely pick whichever matches how your tablet is connected:

• ☁️ Cloud — device-free, works from anywhere. Reads your library straight from reMarkable's cloud over Wi‑Fi with a Connect subscription — no cable, no developer mode. Full read/render plus full write (upload, create folder, move, rename, delete → trash). Parallel fetching and an on-disk blob cache make it fast after the first sync. Best for remote/headless setups or when you don't want to plug in.

• 🔌 USB Web Interface — best when the tablet is plugged in. Enable the web interface in Storage Settings — no subscription, no developer mode. Full read/render plus upload (to your root folder). The tablet's USB web firmware exposes no folder/move/rename/delete endpoints, so for those over a cable use SSH.

• ⚡ SSH — for power users who want filesystem-level access. Requires developer mode over USB. Full read/render plus full write including folder create/move/rename/delete, straight from the tablet filesystem.

¹ Folder ops = create folder / move / rename / delete. Upload and folder ops are enabled by default; pass --read-only to expose a read-only server. Deletes move items to the trash and prompt for confirmation when your client supports elicitation, and are refused without it unless REMARKABLE_SKIP_CONFIRM=1 is set.

Automatic cloud fallback

If you select a device transport (--usb or --ssh) but the tablet isn't reachable at startup and a cloud token is configured (REMARKABLE_TOKEN or ~/.rmapi), the server automatically falls back to cloud mode and logs a warning. This means a single configuration works whether or not the tablet is plugged in — plug in for fast local access, unplug to keep working over the cloud. remarkable_status reports the effective transport and a fell_back_to_cloud flag when this happens.

Pass --no-cloud-fallback (or set REMARKABLE_DISABLE_CLOUD_FALLBACK=1) to disable this and fail instead when the device is unreachable.

📖 Detailed Setup Guides:

• USB Web Interface Setup — recommended — simple setup, full feature support

• SSH Setup Guide — for advanced users who need filesystem access

• Cloud setup is documented in the Quick Install section above; tuning in Cloud Performance & Caching

OpenClaw Integration

remarkable-mcp works as an OpenClaw skill. Add to your openclaw.json:

{
  "mcpServers": {
    "remarkable": {
      "command": "uvx",
      "args": ["remarkable-mcp", "--usb"]
    }
  }
}

Install from ClawHub:

clawhub install remarkable-mcp

Or copy the SKILL.md from this repository into your ~/.openclaw/skills/remarkable-mcp/ directory.

Tools

These six tools are read-only and return structured JSON with hints for next actions. Write tools (remarkable_upload, remarkable_mkdir, remarkable_move, remarkable_rename, remarkable_delete, and remarkable_author for native ink/notebooks) are enabled by default — pass --read-only to disable them — see Write Tools. An interactive canvas app (remarkable_canvas) is also registered automatically for clients that support MCP Apps.

📖 Full Tools Documentation

Smart Features

• Auto-redirect — Browsing a document path returns its content automatically

• Auto-OCR — Notebooks with no typed text automatically enable OCR

• Batch search — Search across multiple documents in one call

• Vision support — Get page images for visual context (diagrams, mockups, sketches)

• Sampling OCR — Use client's AI for OCR on images (no API key needed)

• Tag support — Filter and organize documents by tags

Example Usage

# Read a document
remarkable_read("Meeting Notes")

# Search for keywords
remarkable_read("Project Plan", grep="deadline")

# Enable OCR for handwritten notes
remarkable_read("Journal", include_ocr=True)

# Browse your library
remarkable_browse("/Work/Projects")

# Filter by tags
remarkable_browse("/", tags=["important"])
remarkable_browse("/Work", tags=["project", "active"])

# Search across documents
remarkable_search("meeting", grep="action items")

# Search with tag filter
remarkable_search("project", tags=["work"])

# Get recent documents
remarkable_recent(limit=10)

# Get a page image (for visual content like UI mockups or diagrams)
remarkable_image("UI Mockup", page=1)

# Get SVG for editing in design tools
remarkable_image("Wireframe", output_format="svg")

# Get image with OCR text extraction (uses sampling if configured)
remarkable_image("Handwritten Notes", include_ocr=True)

# Transparent background for compositing
remarkable_image("Logo Sketch", background="#00000000")

# Compatibility mode: return resource URI instead of embedded resource
remarkable_image("Diagram", compatibility=True)

Note: PNG rendering automatically falls back to a source PDF when the local stroke renderer can't produce an image (empty pages, newer .rm formats, or a machine without libcairo). USB and SSH modes use the tablet's native PDF export; cloud mode uses the document's original source PDF. This keeps remarkable_image working across firmware versions and platforms. Cloud mode has no native export, so it relies on the local renderer.

OCR for Handwriting

For handwritten content, remarkable-mcp offers several OCR backends. Choose based on your setup and requirements:

Quick Setup

Set REMARKABLE_OCR_BACKEND in your MCP config:

{
  "env": {
    "REMARKABLE_OCR_BACKEND": "sampling"
  }
}

Options: sampling, google, tesseract, auto

Uses your MCP client's AI model for OCR. Works with clients that support MCP sampling (VS Code + Copilot, Claude Desktop, etc.).

Pros:

• No additional API keys needed

• Quality depends on your client's model (GPT-4, Claude, etc.)

• Private — handwriting stays local to your client

Cons:

• Only available with sampling-capable clients

• Falls back to Google Vision (if API key configured) or Tesseract if sampling unavailable

Provides consistently excellent handwriting recognition.

Setup:

1. Enable Cloud Vision API

2. Create an API key

3. Add to config: "GOOGLE_VISION_API_KEY": "your-key"

Cost: 1,000 free requests/month, then ~$1.50 per 1,000.

📖 Full Google Vision Setup Guide

Open-source OCR designed for printed text. Poor results with handwriting, but useful as an offline fallback.

# Install Tesseract
# macOS
brew install tesseract

# Ubuntu/Debian
sudo apt install tesseract-ocr

# Windows
choco install tesseract

Default Behavior (auto)

When REMARKABLE_OCR_BACKEND=auto (default):

1. Google Vision (if GOOGLE_VISION_API_KEY is set)

2. Tesseract (fallback)

SSH vs USB Web vs Cloud Comparison

📖 SSH Setup Guide

Write Tools (Cloud, SSH & USB Web)

Write tools let you upload, organize, and manage documents on your reMarkable. Enabled by default. Cloud and SSH modes support the full set; USB web supports upload only (its firmware exposes no folder operations). Pass --read-only to expose a read-only server.

Disabling Write Tools (read-only mode)

Write tools are on by default in every mode. To run a read-only server, add the --read-only flag:

{
  "servers": {
    "remarkable": {
      "command": "uvx",
      "args": ["remarkable-mcp", "--read-only"]
    }
  }
}

It combines with any transport flag (--ssh, --usb):

{
  "servers": {
    "remarkable": {
      "command": "uvx",
      "args": ["remarkable-mcp", "--ssh", "--read-only"]
    }
  }
}

Or set the environment variable:

{
  "env": {
    "REMARKABLE_READ_ONLY": "1"
  }
}

The legacy --write flag and REMARKABLE_ENABLE_WRITE variable are still accepted for backward compatibility but are now no-ops (write is the default). --write and --read-only are mutually exclusive.

Available Write Tools

Safety

• Upload registers in all modes — cloud, SSH, and USB web.

• mkdir, move, rename, delete register in cloud and SSH modes only — they are not exposed on USB web (the tablet's USB web firmware has no folder/move/rename/delete endpoints), keeping the tool list scoped to what the active transport actually supports.

• Delete prompts for confirmation when possible — if the client supports MCP elicitation, remarkable_delete asks the user to confirm before deleting. If the client can't show a prompt, the delete is refused (not performed) unless REMARKABLE_SKIP_CONFIRM=1 is set — so write-on-by-default can't silently delete from clients that lack elicitation. In cloud mode delete moves the item to the trash (recoverable from your device); set REMARKABLE_SKIP_CONFIRM=1 to allow deletes without a prompt in automated setups. All write tools carry ToolAnnotations(readOnlyHint=False) (and destructiveHint=True for delete) so an agent harness can gate writes at the MCP layer.

• After each write operation in SSH mode, the tablet UI restarts automatically to reflect changes.

Examples

# Upload a PDF
remarkable_upload("paper.pdf", parent_folder="/Research")

# Create a folder
remarkable_mkdir("2024 Archive", parent="/Archive")

# Move a document
remarkable_move("Meeting Notes", "/Archive/2024 Archive")

# Rename a document
remarkable_rename("Untitled", "Q4 Planning Notes")

# Delete (destructive — confirms via elicitation when supported)
remarkable_delete("Old Draft")

# Author native ink and notebooks (SSH only)
# Append pen/highlighter strokes to a page (coordinates normalized [0,1] from
# the page's top-left). The interactive canvas Save button calls this too.
remarkable_author(
    method="draw", document="Ideas", page=1,
    strokes=[{"points": [[0.1, 0.2], [0.8, 0.2]], "tool": "highlighter", "color": "yellow"}],
)

# Append a blank, drawable page to the end of a notebook
remarkable_author(method="add_page", document="Ideas")

# Create a new (blank) notebook — the common case
remarkable_author(method="create_document", name="Sketches")

# Only seed typed text when the user explicitly requested it.
remarkable_author(method="create_document", name="Meeting notes", text="Agenda\nFollow-ups")

Interactive Canvas App (MCP Apps)

An interactive page viewer built on the MCP Apps extension (SEP-1865). Clients that support MCP Apps (such as ChatGPT, Claude, VS Code, and the MCP Inspector) render a canvas in a side panel where you can view a document page and navigate through it.

There is no flag to enable it — the remarkable_canvas tool and its ui://remarkable/canvas resource are always registered, and the capability is negotiated automatically at the MCP initialize handshake. App-capable clients open the interactive canvas; every other client simply receives the rendered page as an image, so the tool is safe and useful everywhere.

This registers one tool:

How it behaves:

• App-capable clients open the canvas (declared at ui://remarkable/canvas, MIME text/html;profile=mcp-app) and can page through the document via the MCP Apps postMessage bridge — the server delivers each rendered page in the tool result's structuredContent.

• Other clients still get the rendered page back as an embedded PNG image, so the tool is useful everywhere; it just won't open the interactive panel. The _meta.ui / ui:// metadata is inert to clients that don't advertise the MCP Apps UI extension.

Drawing and authoring from the canvas

When write mode is on (the default) and the active transport is SSH, the canvas becomes a write surface:

• Draw — pick a pen or highlighter and colour, draw over the page, and Save writes the strokes back to the device as native .rm ink. Strokes are buffered locally per page (with Undo and Cancel) and only touch the device on Save.

• ＋ Page (native notebooks only) — queues a new blank page locally that you can navigate to and draw on immediately. Save materializes the queued page(s) on the device first, then writes any cached strokes.

• One source of truth: the canvas calls the same remarkable_author tool a model would call (method="draw" on Save, method="add_page" for ＋Page), so the human path and the model path produce byte-identical results.

The Save / Draw / ＋Page controls are hidden when the page isn't writable (read-only mode, or a non-SSH transport), and the canvas falls back to a plain image viewer. The iframe bridge follows the MCP Apps spec but is best validated against your specific client.

Advanced Configuration

Root Path Filtering

Limit the MCP server to a specific folder on your reMarkable. All operations will be scoped to this folder:

{
  "servers": {
    "remarkable": {
      "command": "uvx",
      "args": ["remarkable-mcp", "--ssh"],
      "env": {
        "REMARKABLE_ROOT_PATH": "/Work",
        "GOOGLE_VISION_API_KEY": "your-api-key"
      }
    }
  }
}

With this configuration:

• remarkable_browse("/") shows contents of /Work

• remarkable_browse("/Projects") shows /Work/Projects

• Documents outside /Work are not accessible

Useful for:

• Focusing on work documents during office hours

• Separating personal and professional notes

• Limiting scope for specific AI workflows

Custom Background Color

Set the default background color for image rendering:

{
  "servers": {
    "remarkable": {
      "command": "uvx",
      "args": ["remarkable-mcp", "--ssh"],
      "env": {
        "REMARKABLE_BACKGROUND_COLOR": "#FFFFFF"
      }
    }
  }
}

Supported formats:

• #RRGGBB — RGB hex (e.g., #FFFFFF for white)

• #RRGGBBAA — RGBA hex (e.g., #00000000 for transparent)

Default is #FBFBFB (reMarkable paper color). This affects both the remarkable_image tool and image resources.

Retry Configuration

Cloud API requests automatically retry on transient failures (HTTP 429, 500, 502, 503, 504) and network errors with exponential backoff and jitter. You can tune this via environment variables:

The retry logic honours the Retry-After header from rate-limited responses — both the numeric (seconds) form and the HTTP-date form (which Cloudflare, fronting the reMarkable cloud, often sends) — capped at 20 seconds. Auth failures (401) are not retried — they trigger automatic token renewal instead.

Cloud Performance & Caching

Cloud mode is built to make a device-free workflow fast:

• Parallel traversal — document metadata is fetched concurrently instead of one document at a time, turning a multi-minute first load into a few seconds.

• Connection pooling — HTTP connections are reused (keep-alive), avoiding a fresh TLS handshake per request.

• Content-addressed blob cache — reMarkable's cloud is an immutable, hash-addressed store (like Git), so a blob's bytes can never change for a given hash. Downloaded blobs are cached on disk and reused on later runs; changed documents get new hashes and are re-fetched automatically. This makes warm startups and repeat document reads near-instant, and it is invalidation-safe by construction.

You normally don't need to configure any of this, but these environment variables let you tune it:

The cache is purely a local accelerator: deleting REMARKABLE_CACHE_DIR only forces the next read to re-download. The mutable cloud root hash is always fetched fresh, so you never see a stale library.

Use Cases

Research & Writing

Use remarkable-mcp while working in an Obsidian vault or similar to transfer knowledge from your handwritten notes into structured documents. AI can read your research notes and help develop your ideas.

Daily Review

Ask your AI assistant to summarize your recent notes, find action items, or identify patterns across your journal entries.

Document Search

Find that half-remembered note by searching across your entire library — including handwritten content.

Knowledge Management

Treat your reMarkable as a second brain that AI can access. Combined with tools like Obsidian, you can build a powerful personal knowledge system.
