July 8, 2026 The biggest release day yet: v0.23.0 → v0.27.0 (twenty-three MCP releases) plus panel 0.6.6 → 0.6.8. Two headlines: any LLM can now drive ComfyUI — including free local models (blog post), and remote ComfyUI became a first-class citizen — one command to connect, a custom RunPod image, and a secure tunnel bridge. In the run-up (panel 0.4.7 → 0.6.5, July 1–7), the panel became a pure frontend extension — it never spawns the orchestrator, which cleared the Comfy Registry’s security-scanner flag that had blocked every published version — and picked up remote-pod support (auto-target the ComfyUI you’re viewing, secure-bridge discovery, per-shell copy for the connect command) plus fixes for Ctrl+C/Esc interrupt and wss:// reconnect wedges.

​
Local LLMs: Ollama backend, compact tool mode, the fine-tune ladder

  • Ollama backend — drive the sidebar panel with a local LLM. No API keys, no subscription, no cloud.
  • Compact tool mode (#97) — a reduced tool surface sized for small models, which also unlocked Hermes Agent, OpenClaw, and Copilot CLI as first-class backends, plus any OpenAI-compatible endpoint.
  • gemma4-comfyui-mcp fine-tune ladder is the local default (also panel 0.6.7) — our Gemma 4 fine-tunes tuned specifically for these tools, with model-aware num_ctx instead of a hard 16K clamp.
  • ComfyUI LLM Arena — a tiered benchmark harness that scores models on real ComfyUI agent tasks, plus compact-mode catalog search over param docs.
  • Local models stop flying blind — a dedicated system prompt, forgiving tool dispatch, markdown reconciliation, and a cold-load keepalive.
  • VRAM sharing — local-model VRAM is freed during a render and chat pauses until it finishes, so a 12B model and an SDXL render can share one GPU.
  • Tool-loop breaker — identical repeat calls are blocked and the turn ends after 4 repeats, so a small model can’t spin forever.

​
Remote ComfyUI: connect, secure bridge, relay

  • npx -y comfyui-mcp connect <url> — one command on your machine drives a remote ComfyUI (a RunPod pod, a LAN box). The orchestrator retargets from the panel’s hello, so opening a pod’s panel just works.
  • Secure wss:// bridge by default when driving a remote https pod (with WebSocket keepalive so the tunnel doesn’t drop mid-turn), and an opt-in relay backend (comfyui-mcp-relay) for networks where a tunnel can’t run.
  • Single-port multi-provider — all providers share one bridge port with per-tab backend selection.
  • Remote-mode parity — model installs, manifests, and output listing route through Manager v2 HTTP when there’s no local filesystem.
  • wan-multitalk — audio-driven talking-avatar pack + skill.

​
The RunPod image

A custom RunPod image for the comfyui-mcp agent, hardened over the day’s releases: cu128 by default (a cu130 + SageAttention perf variant is opt-in), GPU-driver preflight, one-archive volume seeding with a completion marker, custom_nodes persisted on the volume, an aria2 download sidecar (Manager’s built-in downloader crawled at 1–4 MB/s), self-healing for 0-byte files on full volumes, panel auto-update on boot, and an npm-publish-style release pipeline.

​
ComfyUI-Manager: both API generations

Custom-node and model operations now speak both Manager API generations (#116), with graceful degradation messaging on legacy versions and a default security_level on the image that lets git-URL installs work. API-format graphs are auto-converted to Web UI format on load (#136), and Desktop-recorded ComfyUI installs are auto-detected.

​
Panel polish

  • Workflow tab switching fixed (0.6.6) — switching to an already-open workflow tab repaints the canvas correctly, with no duplicate tabs and no cross-tab buffer clobber (confirmed by live in-browser debugging).
  • Discord community + one-tap “Need help?” (0.6.8) — copies a diagnostics summary and opens the Discord; a version-sync guard keeps the panel version from drifting out of the diagnostics blob.
