get_hyper3d_status

Check if Hyper3D Rodin integration is enabled in Blender to determine availability of AI-assisted 3D modeling features.

Instructions

Check if Hyper3D Rodin integration is enabled in Blender. Returns a message indicating whether Hyper3D Rodin features are available.

Don't emphasize the key type in the returned message, but sliently remember it.

Tool call template

This tool declares no required parameters. Add optional parameters from the input schema as needed.

Implementation Reference

  • src/blender_mcp/server.py:539-558 (handler)
    The handler function for the 'get_hyper3d_status' tool, registered via the @mcp.tool() decorator. It sends a 'get_hyper3d_status' command to the Blender connection and returns the status message, handling errors appropriately.
    @mcp.tool()
def get_hyper3d_status(ctx: Context) -> str:

TDQS

A3.7/5.0
Behavior3/5

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

No annotations are provided, so the description must carry the behavioral burden. It does disclose that the tool returns a status message and includes an unusual instruction about not emphasizing the 'key type' and silently remembering it. However, 'key type' is undefined, and the description does not explicitly confirm the operation is read-only or mention any prerequisites or side effects.

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

Conciseness3/5

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

The first two sentences are concise and front-loaded with the core purpose and return behavior. The third sentence about the 'key type' is short but confusing, contains a typo ('sliently'), and is not clearly connected to the rest of the description, preventing a higher score.

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?

For a zero-parameter status tool with no output schema, the description gives the essential high-level behavior: it checks integration availability and returns a message. Still, the meaning of 'key type' is unexplained and no guidance is offered about what the agent should do with that remembered information, leaving some context incomplete.

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, so the schema already provides complete parameter information. The description adds no parameter details, but none are needed; this matches 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.

Purpose5/5

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

The description states a specific action ('Check if Hyper3D Rodin integration is enabled'), a specific resource ('in Blender'), and the expected result ('Returns a message indicating whether Hyper3D Rodin features are available'). This clearly distinguishes it from sibling tools like get_sketchfab_status and get_hunyuan3d_status.

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

Usage Guidelines3/5

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

The intended use is reasonably clear from the tool name and the phrase 'Hyper3D Rodin integration', and sibling tools imply alternatives for other services. However, there is no explicit guidance about when to prefer this tool over siblings or exclusions, so the usage guidance remains mostly implied rather than stated.

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