Godot MCP

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states what the tool does but lacks critical details: whether this launches the editor in a new process, if it requires specific permissions, what happens if the project path is invalid, or if there are any side effects like locking files. For a tool that likely involves system-level operations, this is a significant gap.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, efficient sentence that directly states the tool's purpose without unnecessary words. It's front-loaded and wastes no space, making it easy to parse quickly.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the complexity of launching an external editor (which likely involves system interactions and potential errors), the description is insufficient. With no annotations, no output schema, and minimal behavioral details, it fails to provide enough context for safe and effective use, especially compared to siblings that might have overlapping or related functions.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has 100% description coverage, with the single parameter 'projectPath' clearly documented as 'Path to the Godot project directory'. The description adds no additional semantic context beyond what the schema provides, such as format examples or constraints, but the schema does the heavy lifting, justifying a baseline score.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb ('Launch') and resource ('Godot editor for a specific project'), making the purpose immediately understandable. It doesn't explicitly differentiate from siblings like 'run_project' or 'list_projects', but the action is specific enough to be distinguished by context.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus alternatives like 'run_project' (which might execute a project without launching the editor) or 'list_projects' (which might show available projects). There's no mention of prerequisites, such as needing the Godot editor installed or the project being valid.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
