Add HTTP/SSE test scripts demonstrating remote server usage
New Scripts: - demo-http-api.js: Simple demo showing HTTP server is accessible TODAY - test-http-mcp.js: Full MCP protocol test over HTTP/SSE - npm run test:http: Run HTTP/SSE MCP protocol tests Purpose: Demonstrates that while major AI tools don't support HTTP/SSE MCP yet, the deployed server IS accessible and usable right now for: - Custom integrations (web apps, bots, extensions) - Testing the MCP protocol over HTTP - Future-proofing for when tools add support Usage: node demo-http-api.js # Quick demo (works now) npm run test:http # Full MCP protocol test Dev Dependencies Added: - eventsource: For SSE client connections - node-fetch: For HTTP requests Shows Real Value: - Server is deployed and working at hpr-knowledge-base.onrender.com - Can be integrated into custom apps TODAY - Ready for future MCP client adoption - Not just waiting for tool support This addresses the question: "Did I build something nothing supports?" Answer: No! It's accessible now for custom code, and ready for the future. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
