Re: Ask HN: Why do we need MCP?
#22MCP and APIs are extremely similar, but MCP provides a common protocol that everyone can follow, so every agent can use the same protocol regardless of whether the backend uses REST, OpenAPI, or GraphQL. It will just work, and agents know how to crawl other MCPs; therefore, providing an MCP tool makes it much easier for an agent to develop a usage pattern.

#23I use CLI tools for Git, Atlassian (ACLI), and Metabase, plus custom SigNoz shell scripts to drive API calls instead of an MCP server. This setup works very well at the moment for me.
I run a few agents side by side and I've been going back and forth on whether to bother with MCP servers at all. I'm not clear on what each of those is doing in your loop though. Could you go into a bit more detail?
