MCP server de Divoom LAN Watchface

mcp-divoom-lan

mcp-divoom-lan is an open-source MCP server for TimesFrame/AstroToo watchfaces and PIXOO64/TimeGate LAN display control. TimesFrame/AstroToo query Device/GetHardwareVersion; PIXOO64/TimeGate use discovery Hardware or explicit hardware profiles. Unknown hardware is rejected. The TimesFrame no-response fallback is retained after checking available discovery data.

PIXOO64 Hardware 90/92 uses 80/post; 96 uses 9000/divoom_api. Its 10 dedicated tools send display elements, text, RGB animations and control commands. Hardware 96 command lists execute sequentially in MCP to match the reference firmware. See the PIXOO64 guide and examples. Device firmware is unchanged.

It works together with the v2 HTML visual editor for modifying watchfaces, switching faces, adjusting brightness, and creating new local watchfaces.

TimeGate Hardware 400 uses 80/post; 402 uses 9000/divoom_api. Its 10 dedicated tools control five independent 128×128 screens and require LocalToken from device settings. Hardware 402 batches run sequentially in MCP. See the TimeGate guide for per-version field, alignment and background differences. Device firmware is unchanged.

v2 visual editor (public):

• GitHub: https://github.com/DivoomDevelop/divoom-watchface-visual-editor_v2
• Live site: https://divoomdevelop.github.io/divoom-watchface-visual-editor_v2/

Your local clone path (e.g. D:\divoom-watchface-visual-editor) is machine-specific; use the v2 GitHub / GitHub Pages URLs above in docs and MCP metadata.

Goals

• Expose key capabilities from Divoom_Watchface_Remote_Customization_Guide_EN.md as MCP tools
• Let MCP-enabled clients (Cursor, Claude Desktop, local LLMs, etc.) drive watchface actions via natural language
• Preserve safety boundaries (read before write, explicit warnings for risky operations, multipart rules)

Default safety policy (important)

• Select the product profile: Hardware 510/511/512 selects TimesFrame; 530 AstroToo; 90/92/96 PIXOO64; 400/402 TimeGate. Explicit target.hardware is a caller profile override. Use pixoo64_* or timegate_* for those products; managed-watchface rules below apply to TimesFrame/AstroToo.
• Internal managed slot: users and MCP clients omit ClockId from create and patch calls. The server injects its managed slot, reads it first, creates it when missing, and updates it when present.
• Read before write: the MCP server prechecks its managed slot, writes, and then clients should read back to verify.
• If GetLocalClockInfo returns an empty ItemList: stop writes; switch to an editable watchface first.
• Prefer watchface_patch_local for edits. Use watchface_create_local_clock when the user asks to create a watchface or when intentionally replacing the complete managed configuration and backdrop.

Implemented tools (42)

Discovery tool (1):

• watchface_list_devices → returns selectable TimesFrame/AstroToo/PIXOO64/TimeGate targets with product-specific default ports

Device tools (15):

• watchface_get_device_info → hardware identification and LAN capability report
• watchface_get_local → Device/GetLocalClockInfo
• watchface_patch_local → managed-slot upsert with no caller-supplied ClockId. Existing configurations use Device/PatchLocalClockInfo; a missing configuration is created when a backdrop and complete item tables are supplied.
• watchface_get_fonts_local → Device/GetLocalFontList
• watchface_get_store_market_list → Device/GetStoreClockMarketList
• watchface_set_clock_select → Channel/SetClockSelectId (TimesFrame queues a paired request inside one serialized MCP operation so a manual selection suppresses the active traditional schedule for the current period; AstroToo sends once)
• watchface_get_brightness → Sys/GetBrightness
• watchface_set_brightness → Channel/SetBrightness
• watchface_onoff_screen → Channel/OnOffScreen (1=on, 0=off)
• watchface_replace_dial_bg_file → POST /replace_clock_dial_bg
• watchface_upload_file → AstroToo-only POST /upload_local_asset; returns a temporary local:// staging reference consumed by a successful create/patch. AstroToo keeps product photo/pixel POST /upload separate. TimesFrame generic /upload is blocked in local-only MCP mode.
• watchface_create_local_clock → managed-slot multipart upsert with no caller-supplied ClockId: /create_local_clock when missing and /patch_local_clock when already present.
• watchface_reset_local_then_cloud → Device/ResetLocalClockFromServer
• watchface_get_screen_snapshot → Device/GetScreenSnapshot (downloads the returned AstroToo snapshot path; TimesFrame keeps its WebP fallback)
• watchface_raw_command → generic POST /divoom_api

Offline/model-aware authoring tools (6):

• watchface_protocol_quick_reference → key protocol constraints for the model
• watchface_clock_catalog → product-specific ClockId, Chinese/English names, fonts, disp and item-id semantics; optional native configuration
• watchface_disp_catalog → model-specific disp catalog and filters
• watchface_font_catalog → model-specific font catalog; with a live AstroToo target it merges local availability into the AstroToo names
• watchface_template_search → curated TimesFrame or AstroToo watchface templates
• watchface_layout_suggest → model-specific layout hints; AstroToo never receives TimesFrame coordinate statistics

PIXOO64 tools (10): pixoo64_get_device_info, pixoo64_send_animation, pixoo64_send_items, pixoo64_send_text, pixoo64_clear_text, pixoo64_set_brightness, pixoo64_onoff_screen, pixoo64_set_channel, pixoo64_play_gif, and pixoo64_command_list. Read divoom://pixoo64/guide and divoom://pixoo64/example. A direct LAN target can be { "host":"192.168.1.100", "model":"pixoo64", "hardware":90 }; omit port and DIVOOM_DEVICE_PORT to select the version's default.

TimeGate tools (10): timegate_get_device_info, timegate_send_items, timegate_send_text, timegate_clear_text, timegate_set_brightness, timegate_get_brightness, timegate_onoff_screen, timegate_select_clock, timegate_play_gif, and timegate_command_list. Read divoom://timegate/guide and divoom://timegate/example; authenticated calls supply localToken from the actual device settings.

Resources (context for the model)

Product data is stored by directory: resources/timesframe, resources/astrotoo, resources/pixoo64, resources/timegate, and resources/common. resources/products.json records Hardware mappings, per-screen canvas sizes, directories and routes. Runtime loaders never fall back to another product's data.

The original resource URIs retain TimesFrame semantics. AstroToo has separate 480×480 resources:

• divoom://products/catalog
• divoom://guide/quick-reference
• divoom://skill/watchface-customization
• divoom://font/catalog
• divoom://font/guide
• divoom://disp/catalog
• divoom://watchface/schema
• divoom://watchface/example-minimal
• divoom://guide/ai-watchface
• divoom://templates/curated
• divoom://astrotoo/guide
• divoom://astrotoo/disp/summary
• divoom://astrotoo/disp/catalog
• divoom://astrotoo/disp/guide/en
• divoom://astrotoo/disp/guide/zh-cn
• divoom://astrotoo/font/catalog
• divoom://astrotoo/clocks/catalog
• divoom://astrotoo/clocks/configs
• divoom://astrotoo/templates/curated
• divoom://astrotoo/watchface/example-minimal
• divoom://astrotoo/watchface/schema

MCP Bundle (.mcpb)

For MCPB-compatible hosts (e.g. Claude desktop connectors, Smithery stdio releases), build a local bundle:

1. Install the packer: npm install -g @anthropic-ai/mcpb
2. From this package root: npm run mcpb:pack
3. Output: mcp-divoom-lan.mcpb (gitignored). The staging directory mcpb/staging/ is also gitignored.

The bundle includes dist/, resources/, production node_modules, and a manifest.json with user fields for device IP, port, product detection, and timeout.

Quick start

Published npm package:

{
  "mcpServers": {
    "divoom-lan": {
      "command": "npx",
      "args": ["-y", "mcp-divoom-lan@latest"],
      "env": {
        "DIVOOM_DEVICE_HOST": "192.168.1.120",
        "DIVOOM_DEVICE_PORT": "9000",
        "DIVOOM_DEVICE_MODEL": "auto",
        "DIVOOM_TIMEOUT_MS": "45000"
      }
    }
  }
}

DIVOOM_DEVICE_HOST is optional. Leave it unset and include target.host in each tool call when one MCP server controls multiple devices.

Build from source:

cd tools/mcp-divoom-lan  # or your clone root for this package
npm install
npm run build
npm start

Development (watch rebuild):

npm run dev

Regenerate AstroToo resources from the simulator and Divoom command server:

$env:DIVOOM_ASTROTOO_SIMULATOR_ROOT='D:\work\divoom_product\timebox\trunck\device\tool_src\lv_sim_visual_studio\LvglAstroTooSimulator'
$env:DIVOOM_ASTROTOO_DEVICE_ID='300400436'
npm run build:astrotoo

The generator calls https://appchina.divoom-gz.com/ + command string with a JSON body. It obtains default IDs from Device/GetClockDefaultList (IsDefault=1), font names from Device/GetFontForAI, and missing configurations from Device/GetClockInfoV3.

Pre-release check (typecheck, build, pack dry-run):

npm run release:check

Environment variables

• DIVOOM_DEVICE_HOST — device LAN IP (e.g. 192.168.1.120)
• DIVOOM_DEVICE_PORT — optional override; omit for PIXOO64 90/92 or TimeGate 400 port 80, otherwise 9000
• DIVOOM_DEVICE_MODEL — auto (default), timesframe, astrotoo, pixoo64, or timegate
• DIVOOM_DEVICE_HARDWARE — optional default-device profile: PIXOO64 90/92/96 or TimeGate 400/402; omit to use discovery
• DIVOOM_TIMEGATE_LOCAL_TOKEN — optional LocalToken from the default TimeGate settings; matched by host, otherwise supply localToken per call
• DIVOOM_TIMEOUT_MS — request timeout ms, default 45000

If DIVOOM_DEVICE_HOST is unset, each tool call must pass target.host. To control several devices, pass a different target on each call. The server serializes a complete operation per host while allowing independent devices to run concurrently.

Publishing checklist (for maintainers)

1. Use a dedicated repo (e.g. mcp-divoom-lan) with this package at the repo root.
2. Verify metadata: LICENSE, SECURITY.md, CONTRIBUTING.md, CHANGELOG.md, RELEASE.md as applicable.
3. Run npm run release:check.
4. Tag a GitHub release (e.g. v0.3.0) with screenshots and sample requests if helpful.
5. Submit listings where appropriate (MCP Registry, Smithery, Glama, MCP.so, and community indexes). For Glama, follow GLAMA_SUBMISSION_READY.md (including Dockerfile and glama.json). For MCP.so, follow MCP_SO_SUBMISSION_READY.md. For the Volcengine MCP catalog, see VOLCENGINE_SUBMISSION_READY.md (PR: https://github.com/volcengine/mcp-server/pull/398). For an Alibaba Cloud Bailian custom MCP deployed with npx, see BAILIAN_MCP_SUBMISSION_READY.md. For publishing a Coze HTTP plugin, see COZE_SUBMISSION_READY.md.
6. Minimal demo flow: watchface_get_local → watchface_patch_local (font size/color) → watchface_replace_dial_bg_file (background).

Should the HTML visual editor ship inside this npm package?

Recommendation: no for the core MCP package — keep MCP lean. Offer the editor as a separate optional project.

• Core: https://github.com/DivoomDevelop/mcp-divoom-lan
• Visual editor v2: https://github.com/DivoomDevelop/divoom-watchface-visual-editor_v2
• Hosted v2: https://divoomdevelop.github.io/divoom-watchface-visual-editor_v2/

Benefits:

• Small MCP install suitable for all AI clients
• Non-developers can use the visual UI to understand ItemList, then let the AI apply patches
• Clear split between WYSIWYG editing and automated MCP writes
