A3.6/5.0
Scored across 9 tools
Disambiguation4/5
Most tools have clearly distinct purposes (execute, list players, get info, whitelist, op, connection check). The only potential confusion is between mc_execute_command and mc_execute_as_op, but the descriptions clarify the difference, making misselection unlikely.
Naming Consistency4/5
All tools share the 'mc_' prefix and mostly follow a verb_noun pattern (e.g., mc_list_players, mc_whitelist_add). A few names like mc_op and mc_deop are shorthand rather than verb_noun, and mc_execute_as_op includes a preposition, creating minor inconsistencies but the pattern is still readable and predictable.
Tool Count5/5
With 9 tools, the server covers RCON command execution and common admin operations without being bloated. Each tool serves a clear management function, and the number is well within the ideal range for a focused server.
Completeness4/5
The tool set covers essential RCON features: command execution, player listing, server info, whitelist management, op management, and connection checking. Minor gaps exist like ban/unban or whitelist listing, but these are not critical for basic server administration and can be worked around via mc_execute_command.
