hf-mcp-server

The server's design focuses on proxying and facilitating interactions with external Hugging Face APIs and Gradio Spaces. It handles authentication via Hugging Face tokens, which can be provided in the Authorization header or as a `DEFAULT_HF_TOKEN` environment variable. The `start.sh` script explicitly warns about the security implications of `DEFAULT_HF_TOKEN`, indicating awareness of this risk. Extensive network interactions occur with `huggingface.co` and `*.hf.space`. CORS is configured with a default allowlist but is overrideable via environment variables. Input validation for tool calls is performed using `zod` schemas, mitigating common injection risks. While the server constructs commands for remote job execution (e.g., `uv run` commands for the Hugging Face Jobs API), it does not execute these commands locally, shifting that security boundary to the remote Hugging Face Jobs platform. No direct instances of `eval()` for local server execution were found. The primary security considerations for operators revolve around secure management of Hugging Face API tokens and careful configuration of environment variables, especially `DEFAULT_HF_TOKEN` and `CORS_ALLOWED_ORIGINS`.
