It's much easier to give your agents the LSP for the language(s) it's working on.

A project that turns them into MCP: https://github.com/isaacphi/mcp-language-server

Easier, sure.

LSP has many more "functions" that are useful to agents, such as rename and get definition/usage.

I'm not convinced that ASTs are meaningfully helpful in the grand scheme and the long-run. LSPs and code intelligence I find useful as a human and for my coding agent.
