Quick Install

Prerequisite: install uv

The commands below use uvx, which is included with uv. Page images are rasterized with PyMuPDF; no system Cairo, browser, or graphics runtime needs to be installed on macOS, Linux, or Windows.

macOS and Linux

Use the official standalone installer:

curl -LsSf https://astral.sh/uv/install.sh | sh

Or install with Homebrew:

brew install uv

Windows

Use the official standalone installer from PowerShell:

powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"

Or install with WinGet:

winget install --id=astral-sh.uv -e

Choose a connection

Start with the first mode that fits your setup.

USB Web Interface

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

1. Connect your reMarkable via USB
2. On your tablet, open Settings > Storage and enable USB web interface
3. Install via the button above

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

Local Directory Mode

Read the official reMarkable desktop app's sync folder from disk. This mode is offline and read-only. The desktop app controls synchronization.

{
  "servers": {
    "remarkable": {
      "command": "uvx",
      "args": ["remarkable-mcp", "--local-dir"]
    }
  }
}

{
  "servers": {
    "remarkable": {
      "command": "uvx",
      "args": ["remarkable-mcp", "--local-dir", "/path/to/xochitl-data"]
    }
  }
}

Cloud Mode

Cloud mode works without a device connection and requires a reMarkable Connect subscription.

It fetches metadata in parallel and caches content-addressed blobs on disk. See Cloud performance and caching for configuration.

uvx remarkable-mcp --register YOUR_CODE

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

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

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

SSH Mode

SSH provides direct filesystem access and native notebook authoring. It requires developer mode, which factory-resets the tablet when enabled. Use this mode only when USB web, local directory, or cloud mode does not provide the operation you need.

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

See the SSH setup guide for authentication and device setup.

Connection Modes

All modes support reading and rendering. Cloud and SSH support full library management. USB web supports upload to the root folder. Local directory mode is read-only.

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.

² The desktop app itself signs in to the reMarkable cloud to sync; local directory mode just reads whatever the app has already synced to disk.

Automatic cloud fallback

If a selected device transport is unavailable and a cloud credential is configured, the server falls back to cloud mode. A server launched with --local-dir remains read-only after fallback. remarkable_status reports the effective transport and sets fell_back_to_cloud.

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

The transport is resolved once per server process. Restart the MCP server after connecting a device or starting the desktop app if the process already fell back to cloud.

Detailed setup:

• USB web setup
• SSH setup
• Cloud performance and caching

OpenWebUI (Streamable HTTP)

OpenWebUI's native MCP connection uses Streamable HTTP. Start remarkable-mcp on the same machine:

uvx remarkable-mcp --http

Then add http://127.0.0.1:8000/mcp as the MCP server URL in OpenWebUI. The HTTP transport combines with --usb, --ssh, and --read-only; for example:

uvx remarkable-mcp --usb --http

The bind address and port can also be set with --host / --port or REMARKABLE_MCP_HOST / REMARKABLE_MCP_PORT.

The server uses MCP Python SDK 2.x's dual-era endpoint. Modern 2026-07-28 requests are sessionless; older clients continue to use the initialize handshake and legacy MCP sessions on the same /mcp route. The reMarkable token and selected tablet transport remain process-local CLI/env configuration and are never inferred from MCP HTTP authorization headers.

[!WARNING] Streamable HTTP has no built-in authentication. It binds to 127.0.0.1 by default. Keep that default unless you control the network boundary. Wildcard binds such as 0.0.0.0 and :: are rejected because they cannot provide a strict Host allowlist. A concrete non-loopback address is allowed but exposes every enabled tool, including writes, to clients that can reach the port.

Remote access through an authenticated reverse proxy

Keep remarkable-mcp on its default loopback bind and put the proxy on the same host. MCPServer's DNS-rebinding protection only permits loopback Host and Origin values by default. A proxy that forwards its public hostname unchanged will therefore receive 421 Misdirected Request; a public browser Origin will receive 403 Forbidden.

The proxy must authenticate requests, rewrite Host to the loopback upstream, and clear Origin. For example, with nginx and an existing htpasswd file:

location /mcp {
    auth_basic "reMarkable MCP";
    auth_basic_user_file /etc/nginx/remarkable-mcp.htpasswd;

    proxy_pass http://127.0.0.1:8000;
    proxy_http_version 1.1;
    proxy_buffering off;
    proxy_read_timeout 3600s;

    # Required by MCPServer's default DNS-rebinding protection.
    proxy_set_header Host 127.0.0.1:8000;
    proxy_set_header Origin "";
}

Do not expose the upstream port directly. Configure OpenWebUI with the authenticated proxy URL, such as https://mcp.example.com/mcp.

For NixOS, remarkable-mcp-bridge.nix provides a systemd module with the same loopback default:

{
  imports = [ ./remarkable-mcp-bridge.nix ];
  services.remarkable-mcp = {
    enable = true;
    command = "/opt/remarkable-mcp/.venv/bin/remarkable-mcp";
  };
}

The service user must have its reMarkable credentials under /var/lib/remarkable-mcp (or the configured home).

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 next-step hints. Supported transports also register write tools by default; pass --read-only to disable them. See Write Tools. Clients that support MCP Apps can also open remarkable_canvas.

Full tools reference

Tool behavior

• Browsing a document path returns its content.
• Empty notebook text can trigger OCR automatically.
• Search can scan several matching documents.
• Image tools return visual content that text extraction misses.
• OCR uses Google Vision when configured and otherwise runs locally with Tesseract.
• Browse and search accept tag filters.

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
remarkable_image("Handwritten Notes", include_ocr=True)

# Composite an imported PDF page with its reMarkable annotations
remarkable_image("Research Paper", page=3, render_merged=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 uses PyMuPDF for both notebook SVGs and PDF pages, so remarkable_image does not require Cairo, Inkscape, Chromium, or another system graphics runtime. If local stroke parsing cannot handle a page, USB and SSH modes fall back to the tablet's native PDF export and cloud mode falls back to an original source PDF when one exists.

OCR for Handwriting

For handwritten content, remarkable-mcp offers two OCR backends:

Quick Setup

Set REMARKABLE_OCR_BACKEND in your MCP config:

{
  "env": {
    "REMARKABLE_OCR_BACKEND": "auto"
  }
}

Options: auto, google, tesseract

# 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)

Write Tools by Transport

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

Disabling Write Tools (read-only mode)

Write tools are on by default in each write-capable mode. Local-directory mode is always read-only. To make another transport read-only, 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 cloud, SSH, and USB web mode — local-directory mode never exposes write tools.
• 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. MCP SDK 2.x carries that prompt as a multi-round input request for 2026-07-28 clients and as push elicitation for legacy clients. 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. Cloud and SSH move items to Trash by default. SSH also supports permanent=True for an explicitly requested permanent removal; cloud permanent deletion remains a Trash-management operation in the app/tablet. Set REMARKABLE_SKIP_CONFIRM=1 to allow deletes without a prompt in automated setups. All write tools carry ToolAnnotations(read_only_hint=False) (and destructive_hint=True for delete) so an agent harness can gate writes at the MCP layer.
• SSH work is fair and serialized per server — one FIFO dispatcher owns every SSH subprocess, so startup scans, reads, uploads, mutations, and refresh probes cannot churn the tablet's USB CDC connection concurrently. Cached metadata reads bypass the queue.
• Concurrent SSH writes share a refresh barrier — near-simultaneous writes are persisted in FIFO order, then every participating call waits for one shared xochitl restart before reporting success. A bounded debounce coalesces bursts without background or late success.
• Retries are deliberately narrow — only connection failures that prove the remote command never started (for example connection refused, connect timeout, or banner timeout) receive bounded exponential backoff. Ambiguous/post-start write failures are never replayed; the error directs the caller to refresh and inspect the tablet instead.
• For explicit bulk operations, pass defer_restart=True to each write (including remarkable_author) — or set REMARKABLE_DEFER_RESTART=1 — and call remarkable_refresh() once at the end. Deferred writes return immediately with refresh_pending: true.
• USB HTTP requests use the same bounded operation core with REMARKABLE_USB_MAX_CONCURRENCY (default 2). Cloud sync keeps its existing pooled, idempotency-aware request layer and REMARKABLE_SYNC_WORKERS control.

Examples

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

# Render Markdown and upload the PDF without creating a local file
remarkable_markdown_to_pdf(
    "# Meeting Notes\n\n- Follow up with Sam",
    document_name="Meeting Notes",
    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")

# Permanently delete in SSH mode only
remarkable_delete("Disposable Test", permanent=True)

# Bulk import (SSH): defer the restart on each write, then refresh once.
# One xochitl restart for the whole batch instead of one per upload.
remarkable_upload("a.pdf", parent_folder="/Research", defer_restart=True)
remarkable_upload("b.pdf", parent_folder="/Research", defer_restart=True)
remarkable_refresh()

# 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
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 in client capabilities (modern discovery or a legacy 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 wire result's structuredContent (structured_content in Python).
• 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: choose a pen or highlighter, draw, then save native .rm ink to the device.
• Add page: queue a blank native notebook page, draw on it, then save.
• 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, such as #FFFFFF
• #RRGGBBAA: RGBA hex, such as #00000000

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:

Rate-limit retries honor numeric and HTTP-date Retry-After values, capped at 20 seconds. Authentication failures trigger token renewal instead of retry.

Cloud Performance & Caching

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

• Parallel traversal: fetch document metadata concurrently.
• Connection pooling: reuse HTTP connections.
• Content-addressed blob cache: reuse immutable blobs by hash and fetch new hashes when documents change.

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.

Common Workflows

• Read recent notes and extract action items.
• Search names, tags, typed text, and OCR output.
• Review annotated PDFs with the source page and annotations together.
• Move selected notes into another local workflow.
• Upload reference PDFs or generated Markdown documents.
