![ComfyUI MediaHub banner](assets/mediahub-banner.png) ## Why MediaHub MediaHub aims to bring the world's useful, popular, and capable generative media APIs into ComfyUI through clear, composable nodes. The number of providers currently supported is still limited by the provider accounts and API access available to the maintainer. This is an open invitation to the wider community: pull requests for new providers and improvements are welcome, issue reports are valuable, and coding agents are welcome to contribute when they follow the project's architecture and verification rules. MediaHub keeps provider-specific configuration separate from provider-neutral execution. This lets workflows share a stable image/video execution pipeline without pretending that different providers have identical APIs. ## Supported Providers The first release is planned to include: | Provider | Image | Video | | --- | --- | --- | | MiniMax CN | T2I, I2I | T2V, I2V, first/last-frame video, subject-reference video | | Agnes | Image 2.1 T2I, I2I | Video 2.0 T2V, I2V, multi-image, keyframes | | Seed Volcengine | Seedream T2I, I2I | Seedance T2V, I2V, first/last-frame video | | Alibaba Cloud Bailian CN | Wan image generation/editing | Wan T2V/I2V and HappyHorse T2V/I2V | Provider availability, model access, pricing, regional endpoints, and accepted parameters are controlled by each provider. Final first-release capabilities remain subject to release verification. ## Design Image workflow: ```text Prompt / source image -> Provider Image Config -> MediaHub Generate Image -> Preview Image API Key ---------------------------------------> MediaHub Generate Image ``` Video workflow: ```text Prompt / source image -> Provider Video Config -> MediaHub Submit Video API Key ---------------------------------------> MediaHub Submit Video MediaHub Submit Video -> MediaHub Resolve Video -> SaveVideo API Key -------------> MediaHub Resolve Video ``` - Provider config nodes expose documented provider parameters and validation. - Generic execution nodes do not contain provider dropdowns or provider fields. - Image output connects directly to ComfyUI's `Preview Image`. - Video output connects directly to ComfyUI's built-in `SaveVideo`. - Provider packages are isolated from ComfyUI and from one another. ## Installation ### ComfyUI Registry / Manager Registry installation will be available after the first public release under the node ID `mediahub-cloud`. ### Manual Installation Clone this repository into `ComfyUI/custom_nodes`, install its dependencies with the Python environment used by ComfyUI, and restart ComfyUI: ```bash cd /path/to/ComfyUI/custom_nodes git clone https://github.com/vantang/ComfyUI-MediaHub.git /path/to/ComfyUI/python -m pip install -r ComfyUI-MediaHub/requirements.txt ``` After restart, find nodes under the `MediaHub` category. Importable workflows for every supported provider path are available in [`examples/`](examples/). ## Quick Start 1. Import a workflow from [`examples/`](examples/). 2. Obtain an API key and model access from the selected provider. 3. Enter the key in `MediaHub API Key`. 4. Configure the provider node. 5. Queue the workflow. Provider-specific reference snapshots and implementation notes are stored under [`docs/providers/`](docs/providers/). ## API Key Security The inline password control masks the key on screen only. ComfyUI may still serialize the API key into workflow JSON or generated-media metadata. Before sharing a workflow or generated file: - Remove the API key from the workflow. - Inspect exported workflow JSON and metadata. - Revoke and rotate any key that may have been exposed. Secure local credential storage is not implemented yet. ## Contributing MediaHub needs more providers, tests, documentation, and real-world validation. Human contributors and coding agents are equally welcome. Before implementing a provider: 1. Open or reference an issue describing the provider and operations. 2. Use current official API documentation as the source of truth. 3. Preserve provider and media-family isolation. 4. Add tests, user workflows, deterministic API fixtures, and verification evidence. 5. Never commit provider credentials. Read [`CONTRIBUTING.md`](CONTRIBUTING.md), [`AGENTS.md`](AGENTS.md), and [`docs/AGENT_EXECUTION_PROTOCOL.md`](docs/AGENT_EXECUTION_PROTOCOL.md) before making implementation changes. ## Prompt for Coding Agents Use this prompt when asking an agent to add a provider or operation: ```text Contribute support to ComfyUI-MediaHub. Before editing, read AGENTS.md, docs/CURRENT_STATE.md, docs/DEVELOPMENT.md, docs/AGENT_EXECUTION_PROTOCOL.md, and the latest ComfyUI log. Use the provider's current official API documentation as the source of truth. Save dated documentation evidence under docs/providers// and clearly record endpoints, authentication, models, parameters, accepted values, errors, response formats, and temporary URL behavior. Do not infer one regional API from another. Follow the existing architecture: - keep provider code isolated under mediahub/providers//; - do not import ComfyUI or another provider from provider packages; - keep image, video, and future media families independent; - expose provider-specific parameters in provider config nodes; - reuse provider-neutral execution nodes and stable request/job contracts; - do not add extra_params or provider-name branches to generic services. Add payload/validation/error tests, node-contract tests, user-facing workflows under examples/, deterministic API fixtures under tests/fixtures/, and any required frontend behavior. Run targeted tests, the full suite, static checks, JSON validation, a restarted-ComfyUI smoke test, and explicit live provider verification when credentials are authorized. Update docs/CURRENT_STATE.md with reproducible evidence and remaining gaps. Never print or commit API keys. ``` ## Development Verification ```bash .venv/bin/python -m pytest -q node --check js/mediahub.js .venv/bin/python -m compileall -q . for file in examples/*.json tests/fixtures/*.json; do .venv/bin/python -m json.tool "$file" >/dev/null done ``` After restarting ComfyUI: ```bash .venv/bin/python scripts/smoke_comfyui.py ``` Live provider tests consume provider credits and must be run explicitly. ## Support Use [GitHub Issues](https://github.com/vantang/ComfyUI-MediaHub/issues) for bugs, provider requests, compatibility reports, and implementation proposals. Include the provider, operation, model, ComfyUI version, relevant error output, and a redacted workflow when possible. ## License ComfyUI MediaHub is released under the [MIT License](LICENSE).
