Implementation Reference

  • The handler function for the 'get_scene_info' MCP tool. It establishes a connection to the Blender addon via socket, sends a 'get_scene_info' command, and returns the result as formatted JSON string. Handles connection errors and timeouts.
    @mcp.tool()
    def get_scene_info(ctx: Context) -> str:
        """Get detailed information about the current Blender scene"""
        try:
            blender = get_blender_connection()
            result = blender.send_command("get_scene_info")
            
            # Just return the JSON representation of what Blender sent us
            return json.dumps(result, indent=2)
        except Exception as e:
            logger.error(f"Error getting scene info from Blender: {str(e)}")
            return f"Error getting scene info: {str(e)}"
Behavior2/5

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

With no annotations provided, the description carries full burden for behavioral disclosure. It states what the tool does but doesn't describe how it behaves: no information about what 'detailed information' includes, whether this is a read-only operation, potential performance characteristics, or error conditions. The description is minimal and lacks behavioral context.

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 a single, efficient sentence that directly states the tool's purpose with zero wasted words. It's appropriately sized for a zero-parameter information retrieval tool and front-loads the essential information.

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

Completeness2/5

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

Given no annotations, no output schema, and a description that only states the basic purpose, this is incomplete for a tool that presumably returns scene information. The description doesn't indicate what 'detailed information' includes, the format of returned data, or any constraints on when this can be called. For a tool that likely returns structured scene data, more context would be helpful.

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 zero parameters with 100% schema description coverage, so the baseline is 4. The description appropriately doesn't discuss parameters since none exist, and the schema already fully documents the empty parameter set.

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 action ('Get detailed information') and target resource ('about the current Blender scene'), providing a specific verb+resource combination. However, it doesn't differentiate from sibling tools like 'get_object_info' or 'get_hyper3d_status', which appear to retrieve different types of information.

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. There's no mention of prerequisites, timing considerations, or comparison to sibling tools like 'get_object_info' that might retrieve different scopes of information. The agent must infer usage context from the tool name alone.

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