Common questions

Is Lumen safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 3 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need MCPB on your computer.

lumen

Lux in motu — light in motion. A cross-platform, cross-media conversion engine, written in Rust (edition 2024, rmcp 3.8.0): 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.

Canon machinery (B2, 2026-10-28, D-292/D-312)

Character generation and derivation run against a single canon record per character (canon-record/1), enforced by four tools (15 registered total at 1.0.0; the 11 pre-B2 tools are unchanged):

  • canon_resolve — handle (canon:// / @
  • record SHA-256) → record summary. Lane law in server code: nsfw records are refused to qompass-lane callers; unclassified defaults to nsfw. Records live in the SFW store under the project root (canon/ / .json); lumen never persists an adult record.
  • canon_gate — measurements → verdict over proportion and register bands (ink colour, stroke weight, shadow-edge hardness, saturation/contrast percentiles, key-light direction, iris spec, blush). Drift returns a typed drift_detected refusal with per-metric deltas. PASS releases an artifact to the eye sheet, never to adoption.
  • canon_generate — anchored generation broker. There is no unanchored mode: a job requires a canon handle, an anchor role, the keeper anchor + style-authority hashes among its inputs, and turnaround + plate reference inputs (reference conditioning). Jobs anchored outside the Owner-adopted keeper set are refused pre-generation. Every job persists a workflow-JSON provenance receipt (canon-receipts/ .json, digest-verified; tampering is detectable), and any supplied outputs are gated before the job returns as admitted.
  • canon_convert — handled conversion (1.0.0, R-607): a project PNG is remapped under the record's fingerprint palette (nearest palette colour within its tolerance; out-of-tolerance pixels keep their colour and are counted) and the result is gated against the record's bands before anything is written — drift writes nothing. There is no unhandled mode on this tool; the pre-canon conversion tools keep their existing behaviour without a handle (SPEC §6).

The format/handle/gate crate is crates/lumen-canon (package lumen-canon, lib canon_record), absorbed from the B1 reference implementation without re-derivation.

Also at 1.0.0: the Phase F motion evaluator leg is verified landed in crates/lumen-rig-core (MOTION-EVALUATOR.md), and the sprite→3D fidelity metric (silhouette IoU + landmark Δ) ships in crates/lumen-factory with its first measurement on record (crates/lumen-factory/FIDELITY.md). The server package is lumen-mcp-server 1.0.0 (D-298 rename; the library crate remains lumen). EFLO for the 15-tool surface: EFLO.md. Utilization evidence: UTILIZATION.md.

Verified state (1.0.0, 2026-10-29, both machines)

  • Workspace 557 tests passed / 0 failed / 8 ignored (including lumen-canon's 39), lumen-rig-core 93 / 0, lumen-factory 149 / 0; fmt clean; clippy -D warnings clean (resolved clippy 0.1.100, nightly-2026-09-25 pin) on sandbox and primo; Diver gate at the primo mirror. (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.

Layout

  • src/ — operation core: sprite_ops, inspect, palette, 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.
