🚀 Getting Started with Installation

Installing HF Services MCP Server can be done through both npm scripts and manual Docker commands, providing developers with multiple options based on their specific needs. Both approaches leverage environment variables for configuration, ensuring flexible setup tailored to different deployment scenarios.

To get started using the provided npm scripts:

# Build the Docker image
npm run docker:build

# Run with default settings (SSE transport)
npm run docker:run

# Customize transport type at runtime
npm run docker:run:sse
npm run docker:run:stdio
npm run docker:run:streamableHttp

Alternatively, you can use manual Docker commands to build and run the server:

docker build -t hf-mcp-server .
docker run -p 3000:3000 hf-mcp-server

# Optional: specify transport type or Hugging Face token via env vars
docker run -p 3000:3000 -e TRANSPORT_TYPE=streamableHttp hf-mcp-server
docker run -p 3000:3000 -e HF_TOKEN=your_token_here hf-mcp-server

For direct Node.js execution:

# For specific transport types
node dist/sse.js
node dist/stdio.js
node dist/streamableHttp.js

# Optional custom port configuration
node dist/sse.js --port 8080

These methods ensure ease of use and smooth integration into existing workflows, making HF Services MCP Server accessible to developers across a wide range of environments.
