From ed06ba954be8f317c6c89ffd7f08eeccc83aba20 Mon Sep 17 00:00:00 2001 From: Lee Hanken Date: Sun, 26 Oct 2025 11:39:17 +0000 Subject: [PATCH] Add HTTP/SSE test scripts demonstrating remote server usage MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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. ๐Ÿค– Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- demo-http-api.js | 67 +++++++++++++++++++ package-lock.json | 125 +++++++++++++++++++++++++++++++++-- package.json | 7 +- test-http-mcp.js | 164 ++++++++++++++++++++++++++++++++++++++++++++++ 4 files changed, 355 insertions(+), 8 deletions(-) create mode 100755 demo-http-api.js create mode 100755 test-http-mcp.js diff --git a/demo-http-api.js b/demo-http-api.js new file mode 100755 index 0000000..c6079f1 --- /dev/null +++ b/demo-http-api.js @@ -0,0 +1,67 @@ +#!/usr/bin/env node + +/** + * Simple demo of using the deployed MCP server + * + * This shows how you CAN use the HTTP/SSE server TODAY with custom code. + * While major AI tools don't support it yet, YOU can access it programmatically. + */ + +const SERVER_URL = 'https://hpr-knowledge-base.onrender.com'; + +console.log('๐ŸŽ™๏ธ HPR Knowledge Base - HTTP API Demo\n'); +console.log(`Connecting to: ${SERVER_URL}\n`); + +// Simple fetch-based approach (works NOW) +async function searchHPR(query) { + console.log(`๐Ÿ” Searching for: "${query}"`); + + // For demo purposes, we'll query the health endpoint + // In a real integration, you'd implement the full MCP protocol + const response = await fetch(`${SERVER_URL}/health`); + const data = await response.json(); + + console.log(`โœ… Server is ${data.status}`); + console.log(`๐Ÿ“Š Memory usage: ${data.memory.used} / ${data.memory.threshold}`); + console.log(`๐Ÿ”Œ Active requests: ${data.activeRequests}`); + console.log(`โšก Circuit breaker: ${data.circuitBreaker}\n`); + + return data; +} + +// Example: Your own search function that wraps the MCP server +async function myCustomSearch(topic) { + console.log(`๐Ÿ’ก This is YOUR custom function that queries the MCP server`); + console.log(` You can integrate this into any Node.js app, web app, etc.\n`); + + // In production, you'd implement the full MCP protocol here + // For now, just showing the server is accessible + const health = await searchHPR(topic); + + console.log(`๐ŸŽฏ What you can do with this:`); + console.log(` - Build a custom search UI`); + console.log(` - Integrate with your own AI chatbot`); + console.log(` - Create a Slack bot that queries HPR`); + console.log(` - Build a browser extension`); + console.log(` - Make a Discord bot`); + console.log(` - Anything that runs JavaScript!\n`); + + return health; +} + +// Run the demo +try { + await myCustomSearch('linux'); + + console.log(`โœ… Success!
