Provides tools for Aseprite sprite work, including sprite operations, inspection, palettes, text, style presets, dream-animation automation, QA gates, and file interop; live interop is verified against Aseprite 1.3.18.6-dev.
Integrates with Bevy as an endpoint for game-engine package conversion and model/media workflows, including live BRP interop checks against Bevy 0.18.
Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@lumen export hero.aseprite as a PNG sheet and run the QA gate"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
Lux in motu — light in motion. A cross-platform, cross-media
conversion engine, written in Rust (edition 2024, rmcp 3.3): one
operation core that bridges media formats — 2D art and sprite formats,
3D models, and game-engine packages — converting between them
deterministically from code-first records, so the same input record
yields the same output on any platform. Aseprite sprites and Bevy
were its first endpoints, not its purpose; the center is the factory
(one identity record, emitted as 2D or 3D) and the named, verified
converter chain between formats — one operation core behind three
surfaces —
MCP tools for interactive media work: sprite operations, inspection, palettes, text, style presets, dream-animation automation, QA gates, and export backends (PNG sheets, WASM-4, TIC-80, VoidSprite file interop). All paths are project-root bounded.
An A2A agent surface (v0.3.x JSON-RPC) for dispatched, long-running art jobs, with the trial-then-approval art-director loop as a protocol state. See A2A_DESIGN.md.
A deterministic policy layer (APPA-style, adapted from
archestra-ai/OpenAPPA): every tool call is checked against
lumen-policy.toml before it executes, decisions are replayable,
and denials name the rule they violated. See
POLICY_DESIGN.md.
Companion strategy — pair, don't duplicate — is in COMPANIONS.md. How lumen was built, in what order, and under what governance (including the evidence rule its first failed build produced) is in HISTORY.md.
Build and clippy clean; 303 tests passed / 0 failed / 8 ignored (suite split between validation and adversarial cases).
Live interop gate against real Aseprite 1.3.18.6-dev and Bevy 0.18
BRP (scripts/interop_check.sh): 5 passed / 3 failed — the
failures are documented premise mismatches between lumen's
assumptions and the real tools' behavior; see HISTORY.md.

text, style, dream, qa, export, pipeline, policy,
bevy, doc, vrm, and the a2a/ surface (mod, task, http,
registry).
tests/ — validation and adversarial suites, incl. interop.rs
(live-tool gates, ignored by default).
lumen-policy.toml — the shipped policy; lumen policy check and
lumen policy replay are its gates.
