Hey all -

Been doing database performance work (mostly Postgres/MySQL) for over a decade, and I keep running into the same situation with small teams: no dedicated DBA, but queries are slowing things down as the product grows.

Curious how people here actually deal with it in practice. Do you just wait until something breaks and then dig into EXPLAIN plans yourself? Does one dev end up becoming the "unofficial DBA" by default? Do you use any monitoring tool, or is it mostly guesswork?

Not selling anything, genuinely trying to understand how painful (or not) this actually is for teams without dedicated DB expertise, and what you wish existed to make it easier.

Hi all !

Building an MCP server on top of an existing API and running into spec quality issues — missing descriptions, ambiguous parameters, incomplete schemas. The LLM just picks the wrong tool or calls it badly.
Curious how others are handling this:
• Do you clean up the spec before converting, or fix it after seeing failures?
• Any specific patterns that consistently break tool calling?
• Is this even a real problem at scale or am I overthinking it?

Not selling anything, genuinely trying to understand where the pain is.

Hey everyone!

I’ve just launched corelayer0 (https://corelayer0.com) — it’s live and ready to use now, and I’d love your feedback.

The problem: every API you want to connect to an LLM means writing and maintaining an MCP server by hand (endpoints, auth, types, errors…), and doing it all over again whenever the spec changes.

corelayer0 automates that: you import your OpenAPI spec, it generates a hosted MCP server (one typed tool per endpoint), and you just paste the URL into Claude/ChatGPT/Mistral. You can update the spec anytime — the URL stays stable.

A few design choices: auth is never exposed to the LLM, Code Mode for large APIs, native OAuth 2.1, hosted in the EU / GDPR-native (outside the US CLOUD Act).

Free during the public beta (100 endpoints, 5k calls/month, no credit card) — you can generate a server and test it right away.

What I’m looking for:

• Honest feedback — real need or not?
• Feature ideas (Postman, observability, git-sync already planned)
• Early adopters willing to tell me what breaks

Thanks
