My 'beef' with Cursor is that the editor is part of the package and you don't really have the same kind of hooks into the agent that you do with Claude Code or similar, which really means you're at the mercy of the Cursor team to prioritise those things on their roadmap. That includes things like the limit of 40 MCP tools that you can only enable globally (and MCP proxies that try to do this dynamically are a bit flakey) - even just using the GitHub MCP blows through that limit because it's all or nothing.
It's good for what it is but I don't love that I have to change to a whole-ass new editor to get access to the agentic additions, when alternatives that require an API key or a more flexible CLI tool can do a better job.
