this is exactly how i use it too. i have a few custom MCP servers running on a mac mini homelab, one for permission management, one for infra gateway stuff. the key thing i learned is keeping CLAUDE.md updated with what each MCP server actually does and what inputs it expects. otherwise claude code will either not use the tool when it should, or call it with wrong params and waste a bunch of back and forth. once you document it properly it really does feel like having a team member who just knows how your stack works. the accounting use case is a great example because nobody else's generic tooling would ever cover that.
