The server has 46 tools with consistent naming patterns (all start with action verbs: get_, set_, list_, connect_, disconnect_, add_, remove_, etc.). Descriptions are present for all tools and most parameters, ranging from 40 - 150 characters, adequate but tending toward generic. Parameter schemas are well-defined with types (string, integer, array, boolean) and descriptions. However, output schemas are NOT documented in the source code (only implied by return types like 'str', implying unstructured text output). No tool demonstrates structured output with typed fields. Error handling is minimal, most tools either succeed silently or return generic error strings. The server implements domain-specific MIDI control well (46 tools covering algorithm management, parameter editing, preset control, display, routing, and monitoring), but lacks the output documentation and recovery guidance expected of production-grade agent tools. Tool composition is reasonable, each tool does one task, but chaining is brittle because responses are strings, not structured objects with IDs and references. Security is adequate (no exposed secrets in tool params, MIDI is isolated to MIDI ports), but no audit logging or permission gates are visible.

• Convert all string-returning tools to structured JSON output with typed fields. E.g. list_midi_ports should return {output_ports: [{index: 0, name: 'Disting NT Out'}, ...], input_ports: [...]} instead of formatted text. This enables reliable LLM parsing and tool chaining.
• Document output schemas for all tools in the MCP tool definition. Specify what fields are returned, their types, and what they represent. LLMs need to know what to extract.
• Add error recovery guidance to tool descriptions. E.g. 'If not connected, call connect_disting_nt first with output_port="Disting NT" and input_port="Disting NT".' This reduces failed tool chains.
• Implement confirmation/preview patterns for destructive tools (remove_algorithm, new_preset, reboot). Add a dry_run parameter or split into preview (e.g., preview_remove_algorithm) + confirm (confirm_remove_algorithm) tools.
• Add min/max bounds and enum constraints to numeric parameters. E.g. algo_index description: 'Algorithm slot index (0-based, 0-15)' and display mode description: 'One of: parameters, algorithmUI, overview, overviewVUs'.
• Add pagination to discovery tools (list_midi_ports, get_message_log). Introduce offset/limit or cursor-based parameters and return total_count and has_more fields.
• Document tool prerequisites and chaining paths. E.g. set_parameter_value description: 'First call get_loaded_algorithm to find the slot_index, then get_parameter_info to find param_index, then call this tool.'
• Sanitize file path inputs in install_scala_tuning and install_keyboard_mapping. Restrict to a sandbox directory (e.g. ./tunings/) and validate path does not traverse parent directories.
