My Claude API bill dropped 38% after I rewrote CLAUDE.md.

Same model. Same prompts. Same output quality.
Just one config file changed.

Here's exactly what I fixed 🧵

[Jainish Mistry @itsnullpointer]

At 500 req/hour (TradeGenie load):
38% saving = real money, compounding daily.

This is not theoretical.
This is my actual bill.

[Jainish Mistry @itsnullpointer]

@NexusVoid_Ai That's true. Hard to log or find what and where is failing. That's where debugging skills come to action

MCP just crossed 97 million installs.

Your Spring Boot app can now talk to
ANY AI agent. Out of the box.

Most Java devs haven't heard of it yet.

Here's what it is and why it matters 🧵

Building MCP + Spring AI into my
production stack this week.

Will post the full breakdown — real code,
real costs, real mistakes.

Follow @itsnullpointer if you want
the no-fluff Java AI content.

What's your take — is MCP the
real deal or just hype?

[Jainish Mistry @itsnullpointer]

97M installs in March 2026.

Every major AI provider now ships
MCP-compatible tooling.

If your Spring Boot app isn't MCP-ready,
it won't plug into the agentic stack
being built right now.

This is the time to learn it.

Security Break S2: API Key in Logs

@RequestBody logs your full payload.
Your API key is sitting in your log files right now.
Go grep them. I'll wait.

Fix: Log redaction filter in logback-spring.xml
@JsonIgnore on sensitive fields.
