Jedrzej KosinskiandAmp d7e2683e9d feat(parser): Phase-A descriptor extensions for partner-node parity
Three additive parser changes that unblock bulk porting of partner
nodes from comfy_api_nodes/nodes_*.py without breaking existing
descriptors. Spec: notes/rnp-phaseA-spec.md.

A1 — Custom IO pass-through: any unrecognised string io_type now
builds an opaque IO.Custom socket instead of being rejected. Lets
partner-defined types like RECRAFT_STYLE_V3, RECRAFT_COLOR,
Tripo3DModel, Hunyuan3DMesh round-trip between RNP nodes verbatim.
Applies to both inputs (_parse_input_spec) and outputs
(_parse_outputs).

A2 — control_after_generate round-trip: forwarded into IO.Int.Input
and IO.Combo.Input from the input options dict so seed widgets keep
their randomize/increment/fixed dropdown.

A4 — remote.hidden_forwarded opt-in: non-auth hidden markers
(prompt, extra_pnginfo, dynprompt) now only forward into the request
context when explicitly listed in descriptor.remote.hidden_forwarded.
Default = drop. Auth tokens (auth_token_comfy_org, api_key_comfy_org)
and unique_id are always forwarded when declared. Stops large
EXTRA_PNGINFO blobs from shipping unconditionally.

comfy-remote-nodes

ComfyUI custom-node package that fetches node descriptors from an RNP/1 (Remote Node Protocol v1) server and exposes them as native V3 nodes inside ComfyUI.

The reference server lives at Comfy-Org/comfy-rnp-server (private). This client is intentionally provider-agnostic: any server that speaks RNP/1 can publish nodes through it.

Install

Clone into your ComfyUI custom_nodes/ directory:

cd ComfyUI/custom_nodes
git clone https://github.com/Comfy-Org/comfy-remote-nodes.git

(The directory name on disk doesn't matter — ComfyUI loads the package via spec_from_file_location, so comfy-remote-nodes/ is fine.)

Configure

Point the extension at one RNP server URL via env var before starting ComfyUI:

export RNP_SERVER_URL=http://127.0.0.1:9190
python main.py

If RNP_SERVER_URL is unset, the extension registers zero nodes and logs a single line — ComfyUI starts normally with no remote nodes.

What works today

  • Manifest + capability handshake
  • object_info fetch and dynamic V3 class generation (with ETag conditional GETs)
  • Sync execute and async execute_async + poll/cancel
  • Image / mask / audio / video envelope encode + decode
  • Presigned upload helper for >8 MiB inputs
  • Tier 3 (recent):
    • TASK_LOST detection with idempotent resubmission — survives an RNP server restart mid-task without losing the workflow
    • SERVER_BUSY / MAINTENANCE 503 envelopes treated as rate limits with Retry-After honoring and friendly per-second progress text ("Server busy, retrying in 30s...")
    • Out-of-band url_fetch for URI-only output envelopes, driven by the descriptor's remote.url_fetch policy
    • Per-poll auth refresh so long-running tasks can rotate tokens

What does not (yet)

  • validate_inputs / fingerprint_inputs / check_lazy_status — the server returns 501 NOT_IMPLEMENTED; the client falls through to ComfyUI's defaults
  • Multi-server config file (comfy_remote_nodes.yaml or similar) — today's setup is one server per ComfyUI process via env var
  • Streaming execute (server-sent events for incremental previews)
