alt Hacker NewsThat makes some sense. But one can make the argument given how easy it is to create CLI tools and add new API endpoints, enhancing them is still a better approach than creating and MCP.
I'm not pro or anti-MCP myself. I just haven't had a lot of success using them yet. I've been struggling to find the right balance and every path has lead me to a CLI tool (optionally paired with a skill).
Now I'm not using my cli tools in Claude Chat proper, but I'm not using MCPs either because they just keep failing me. This could very well be a me problem, but I'm still looking for that "ah-ha" moment.
Maybe I'm misunderstanding you, but the way you describe MCP sure sounds like it's just another RPC endpoint. Those are easy to add using traditional methods. Why deal with all the overhead of MCP for those cases?
I don't think MCPs have legs long-term, but they are a great middle ground during this somewhat turbulent transition period we find ourselves in, precisely because they are not the existing tooling (they are greenfield).
An existing company that has an API/CLI might not have everyone on the team on-board with LLMs and agents and what have you – it might be hard to get buy-in to modify those existing surface areas to be more "agent compatible".
Meanwhile, a team within a company that wants to make their company more "agent forward" can build an MCP tomorrow and it is clear what it is for: is a new surface, meant to be consumed by agents, with the needs of agents top-of-mind. It avoids confusing interop issues with existing tooling while maximizing said teams ability to ship changes/experiments quickly.
