What to Do When an API Has Too Many Endpoints for One MCP Server

1+ hour, 56+ min ago   (953+ words) Large APIs are where MCP design gets interesting. If your API has 15 endpoints, you can review each one by hand and decide which operations should become tools. If your API has 300 endpoints, exposing everything creates a different problem: the MCP…...

2+ hour, 20+ min ago   (722+ words) ✓ Human-authored analysis; AI used for formatting and proofreading. A Cognito user pool is an identity perimeter.

5+ hour, 44+ min ago   (245+ words) Password resets, login codes, receipts, and alerts are easier to operate when application email has its own delivery path. Here are the setup decisions that matter before sending. Use a domain you control, then add the DNS records shown by…...

The Purple Gradient Problem: Why AI UI All Looks Alike (and How to Fix It)

9+ hour, 53+ min ago   (799+ words) You can spot it in about three seconds. There's even an origin story. In August 2025, Adam Wathan — the creator of Tailwind CSS — posted a half-serious apology on X that got over a million views. He was sorry, he said, for…...

I tested 31 MCP servers for contract compliance. Only 3% passed.

10+ hour, 30+ min ago   (305+ words) MCP is JSON-RPC over stdio / Streamable HTTP with bidirectional notifications. Normal HTTP chaos tools don't speak it. And even when you test an MCP server, you usually test your agent, not whether the server's contract protects you. Real failures I…...

I banned Claude from saying 'looks reasonable' and it started finding my blind spots

13+ hour, 8+ min ago   (477+ words) I'm in the middle of launching a SaaS product, and the deliverable from one particular session wasn't code. It was an execution plan, plus the design of the quality gates. In other words: writing down "how we're going to build…...
