Scored across 5 tools
Each tool has a clearly distinct purpose: connection info, document retrieval, sample queries, schema listing, and query execution. No overlap between tools.
All tools follow a consistent 'verb_noun' pattern, using 'get_' for four tools and 'run_' for one, which is appropriate for the action. Naming is uniform and predictable.
With 5 tools, the set is well-scoped for a read-only Couchbase MCP server. Each tool serves a clear role without superfluous additions.
The tool set covers core read operations: schema exploration, document retrieval, and querying. A minor gap is the lack of a direct list-documents tool, but that can be achieved via queries.
