Godot multi-project / multi-instance manager built on the Godot-MCP-Native plugin and the gdmcp CLI — create, configure and start/stop Godot editor & headless instances in one click, with a dedicated MCP port per project.
Server has 19 tools with consistent naming (verb_noun pattern) and documented schemas. However, descriptions are generic and lack LLM-optimization guidance. Parameter descriptions exist but are minimal (avg ~40 chars vs baseline 72). Output schemas are not documented. Error handling is absent from visible code. Tool composition is reasonable but some tools combine multiple concerns (e.g., configure_project_mcp does install + enable + write in one call). No tool annotations (readOnlyHint, destructiveHint) despite clear risk levels.
Register an existing Godot project in the manager
One-click MCP environment configuration: install plugin, enable in project, install gdmcp CLI, write mcp_settings.cfg
Create a new Godot project with automatic MCP configuration
Run debug commands on a project via gdmcp (doctor, editor_state, logs, runtime_tree)
Remove a project from the manager and stop all its running instances
Download and extract the Godot-MCP-Native plugin and gdmcp CLI toolchain
Retrieve log history for an instance
Detect MCP environment status for a project (plugin installed, gdmcp CLI present, etc.)
No output schemas documented. Tools return data but LLMs cannot predict field structure, forcing parsing guesses and downstream lookup calls.
Descriptions lack LLM-optimization guidance. Generic phrases like 'Retrieve' and 'Get' do not explain WHEN to call the tool or what makes it distinct from similar tools. Avg description ~50 chars vs baseline 194 chars.
configure_project_mcp combines three concerns (install plugin, enable in project, write config) in one tool. Should split into separate tools so agent can compose them independently.

Retrieve current settings and detected Godot installation path
Retrieve the full aggregated state including settings, toolchain status, projects, and instances
Get the current status of the Godot-MCP-Native toolchain (addon + gdmcp CLI)
Launch a Godot editor, headless, or game instance for a project
Start a game instance via the project's MCP server (run_project tool)
Change the MCP port assigned to a project
Stop a running game instance via the project's MCP server (stop_project tool)
Stop a running Godot instance
Subscribe to real-time state and log events via Server-Sent Events (SSE)
Switch a running editor/headless instance to the other mode (editor ⇄ headless)
Update global settings (godotPath, portBase, webPort, proxy, language)
No error handling guidance visible. Tools lack recovery hints (e.g., 'If project not found, call list_projects first'). No categorization of retryable vs fatal errors.
No tool annotations (readOnlyHint, destructiveHint, idempotentHint) despite clear risk levels. delete_project is DESTRUCTIVE but unmarked; run_game is WRITE but unmarked.
