MCP OpenAPI Template

# Dockerfile for MCP OpenAPI Template Server (SSE/HTTP) # # Architecture: # - FastMCP natively supports SSE transport (no external proxy required) # - Server exposes HTTP/SSE on port 8000 # - Endpoints: /sse (Server-Sent Events), /messages/ (HTTP POST) # # AUTHENTICATION: # This MCP requires authentication via Auth Gateway. # API credentials are dynamically obtained when the user # provides their JWT via the set_auth_token() tool. # # Required environment variables: # - AUTH_GATEWAY_URL: Auth Gateway URL (e.g., https://auth.example.com) # - AUTH_GATEWAY_API_KEY: API Key for Auth Gateway # # Optional environment variables: # - MCP_TRANSPORT: "sse" for HTTP/SSE mode (default in Docker) # - MCP_HOST: Listen host (default: 0.0.0.0) # - MCP_PORT: Listen port (default: 8000) # - AUTH_CREDENTIALS_CACHE_TTL: Credential cache TTL in seconds (default: 3600) FROM python:3.11-slim WORKDIR /app # Install curl for healthcheck RUN apt-get update && apt-get install -y --no-install-recommends curl \ && rm -rf /var/lib/apt/lists/* # Install dependencies COPY requirements.txt .
