Anycubic Cloud MCP (Kobra 3)

Cloud-backed MCP server and helper scripts for Anycubic printers. This uses the reverse-engineered Anycubic cloud REST API (and MQTT where supported) from the hass-anycubic_cloud integration.

Quick Start

Install from GitHub (recommended):

python3 -m pip install "git+https://github.com/aegis-agent/anycubic-cloud-mcp.git"

Install with pipx (isolated CLI):

pipx install anycubic-cloud-mcp

Or from source:

python3 -m pip install -r requirements.txt
python3 -m pip install -e .

Run the MCP server (stdio transport by default):

anycubic-cloud-mcp

HTTP transport (optional):

anycubic-cloud-mcp --http --host 0.0.0.0 --port 8000

HTTP endpoint: http://<host>:<port>/mcp

Configure auth either via environment variables or the auth_set tool.

Environment variables:

• ANYCUBIC_AUTH_MODE: slicer (recommended) or web
• ANYCUBIC_TOKEN: token string
• ANYCUBIC_DEVICE_ID: only for android auth mode

Token Sources

Slicer Next (recommended)

This enables MQTT logon and better status updates.

Windows (Slicer Next):

• Config file:
  • %AppData%\AnycubicSlicerNext\AnycubicSlicerNext.conf
• The access_token value is the token you want.

Extract with the helper script (macOS):

anycubic-slicer-token

Tip: clear access_token in the Slicer config after extracting it to avoid logging out your MCP session when the slicer refreshes.

Web token (REST-only)

• Go to https://cloud-universe.anycubic.com/file
• Sign in
• Open DevTools console
• Run window.localStorage["XX-Token"]
• Copy the token string

MCP Tools

Core tools you asked for:

• printer_list
• printer_status
• print_pause, print_resume, print_cancel
• cloud_file_list, cloud_file_upload, cloud_file_delete
• print_upload, print_cloud_gcode, print_cloud_file
• ace_set_slot, ace_feed_filament, ace_retract_filament, ace_set_auto_feed
• ace_dry_start, ace_dry_stop

Notes:

• slot_index_list is 1-based. Use 1..4 for a single ACE and 1..8 for dual ACE.
• For Kobra 3, Slicer Next tokens are currently the most reliable way to keep MQTT working.

Config File

You can save tokens to a local config file using auth_set with save: true. Default path:

• ~/.config/anycubic-cloud-mcp/config.json

If you prefer a custom path, set:

• ANYCUBIC_CONFIG_PATH=/path/to/config.json

Installer

The installer supports token extraction on macOS and optional SSH sync.

Token extraction (prints token and syncs config to server):

anycubic-cloud-mcp-install token --ssh agent@aegis

Server setup with systemd (HTTP transport):

sudo anycubic-cloud-mcp-install server --systemd --http --host 0.0.0.0 --port 8000

One-shot installer wrapper (uses REPO_URL):

REPO_URL="https://github.com/aegis-agent/anycubic-cloud-mcp.git" scripts/install.sh token --ssh agent@aegis

Pipx bootstrap:

scripts/install.sh --pipx token --ssh agent@aegis

Pipx upgrade (CLI command):

anycubic-cloud-mcp-install pipx --ensure-path

Agent Integrations

Use the installer to register this MCP server with common agent harnesses. Interactive mode shows a selection menu when --targets is omitted.

anycubic-cloud-mcp-install integrate --targets claude-code claude-desktop codex cursor opencode factory vscode

Menu-driven selection:

anycubic-cloud-mcp-install integrate

File-based installs (edit config files instead of using CLIs/deeplinks):

anycubic-cloud-mcp-install integrate --install-mode file --targets claude-code claude-desktop codex vscode

Copy failed raw commands/config to clipboard:

anycubic-cloud-mcp-install integrate --copy-failures

Project-scope installs (Cursor, OpenCode, Factory, VS Code):

anycubic-cloud-mcp-install integrate --targets cursor opencode factory --scope project --project-dir /path/to/project

FastMCP export

Generate a fastmcp.json plus a proxy shim that FastMCP can run:

anycubic-cloud-mcp-install fastmcp --output fastmcp.json

By default it writes anycubic_fastmcp_proxy.py next to fastmcp.json and adds dependencies for fastmcp + anycubic-cloud-mcp. Override with --proxy-path, --dependency, or --no-default-deps.

Notes:

• Cursor user-scope installs return a deeplink; add --cursor-open to open it.
• OpenCode config uses ~/.opencode.json or .opencode.json (project).
• Factory config uses ~/.factory/mcp.json or .factory/mcp.json (project).
• Claude Code config defaults to ~/.claude/mcp.json (override with --claude-config-path).
• Claude Desktop config defaults to ~/.claude/claude_desktop_config.json (override with --claude-desktop-config-path).
• Codex config defaults to ~/.codex/mcp.json (override with --codex-config-path).
• Override user config paths with --cursor-config-path, --opencode-config-path, or --factory-config-path.
• VS Code config uses .vscode/mcp.json (project).

Firmware Note

Firmware version typically does not affect cloud API calls directly, but Anycubic may change auth or API behaviors server-side. If you are stable on 2.4.4.3, you can stay there unless you need fixes in 2.4.5.
