Tools

Functions exposed to the LLM to take actions

Name	Description
run_command	Execute an RCON command on the Minecraft server (without leading slash). Examples: ``say Hello``, ``gamemode creative Steve``, ``tp Steve 0 64 0``
run_command_with_log	Execute an RCON command and capture server log output produced afterwards. `Useful for commands whose feedback appears in the server log rather than the RCON response (e.g. plugin commands that print results via logger). Args: command: The Minecraft command to execute. wait_seconds: Seconds to wait for log output after execution (default 2).`
read_server_log	Read the last N lines from the Minecraft server log file. `Args: lines: Number of lines to read from the end of the log (default 50).`
read_test_log	Read plugin test/debug logs filtered by a configurable prefix. Only lines containing the configured LOG_PREFIX (default ``[TEST]``) are returned. Supports incremental reading: pass the ``position`` value from a previous call as ``since_position`` to only get new entries. Args: since_position: Byte offset to start reading from (0 = beginning). event_filter: Optional event type filter (e.g. ``PASS``, ``FAIL``, ``SUMMARY``). Only lines matching ``{prefix} {event_filter}`` are returned.
query_database	Execute a read-only SELECT query against the plugin's SQLite database. `Write operations (INSERT, UPDATE, DELETE, DROP, etc.) are blocked. Results are returned as a formatted ASCII table. Args: sql: A SELECT SQL statement.`
check_plugin_status	Check overall plugin health: RCON connectivity, recent errors in the server log, and database file status. `Recommended to call before running tests or debugging.`
