Implementation Reference

  • The main handler function for the 'get_polyhaven_status' MCP tool. It connects to Blender via a socket, sends a 'get_polyhaven_status' command, and returns the status message from Blender.
    @mcp.tool()
    def get_polyhaven_status(ctx: Context) -> str:
        """
        Check if PolyHaven integration is enabled in Blender.
        Returns a message indicating whether PolyHaven features are available.
        """
        try:
            blender = get_blender_connection()
            result = blender.send_command("get_polyhaven_status")
            enabled = result.get("enabled", False)
            message = result.get("message", "")
            
            return message
        except Exception as e:
            logger.error(f"Error checking PolyHaven status: {str(e)}")
            return f"Error checking PolyHaven status: {str(e)}"
Behavior2/5

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

No annotations are provided, so the description carries the full burden. It states the tool returns a message about PolyHaven feature availability, but doesn't disclose behavioral traits like whether it's read-only, safe to call frequently, requires authentication, or has rate limits. For a status-check tool with zero annotation coverage, this leaves significant gaps in understanding its behavior.

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

Conciseness5/5

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

The description is extremely concise and front-loaded: two sentences that directly state the purpose and return value. Every word earns its place with no redundancy or fluff. It efficiently communicates the essential information.

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

Completeness3/5

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

Given the tool's low complexity (0 parameters, no output schema, no annotations), the description is minimally complete. It states what the tool does and what it returns, but lacks details on behavioral context (e.g., safety, performance) that would be helpful for an agent. It's adequate but has clear gaps in transparency.

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

Parameters4/5

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

The tool has 0 parameters, and schema description coverage is 100% (since there are no parameters to describe). The description doesn't need to add parameter semantics, so it meets the baseline of 4 for tools with no parameters.

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

Purpose4/5

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

The description clearly states the tool's purpose: 'Check if PolyHaven integration is enabled in Blender.' It uses a specific verb ('Check') and identifies the resource (PolyHaven integration in Blender). However, it doesn't explicitly differentiate from sibling tools like 'get_hyper3d_status' or 'get_scene_info', which are also status-checking tools.

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

Usage Guidelines2/5

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. It doesn't mention prerequisites, timing, or compare it to sibling tools like 'get_hyper3d_status' or other status-checking tools. The agent must infer usage from context alone.

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