Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 15 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00153 | $0.06006 |
| Opus 5 | $0.00077 | $0.03003 |
| Sonnet 5 | $0.00031 | $0.01201 |
| Haiku 4.5 | $0.00015 | $0.00601 |
Grade A, and why
blender-mcp scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 13d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 676 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Blender MCP
Tool Selection
Use structured MCP tools (get_scene_info, screenshot) for quick inspection.
Use execute_python for anything non-trivial: hierarchy traversal, material extraction, animation baking, bulk operations. It gives full bpy API access and avoids tool schema limitations.
Use headless CLI for GLTF exports — the MCP server times out on export operations.
Health Check (Always First)
get_scene_info— verify connection (default port 9876)execute_pythonwithprint("ok")— verify Python worksscreenshot— verify viewport capture works
If MCP is unresponsive, check that the Blender MCP addon is enabled and the socket server is running.
Complete Export Workflow
This is the end-to-end linear narrative. Follow these steps in order. Do not skip steps.
Step 1: Health Check
Confirm MCP is alive before touching anything else:
# In MCP tool call:
get_scene_info
execute_python: print("ok")
screenshot
If any step fails, stop and fix MCP connectivity first. See Known Errors.
Step 2: Inspect Scene
Run the full hierarchy extraction to understand what you're working with:
import bpy, json
def extract_hierarchy(obj, depth=0):
data = {
"name": obj.name,
"type": obj.type,
"location": list(obj.location),
"rotation": list(obj.rotation_euler),
"scale": list(obj.scale),
"visible": not obj.hide_viewport,
"children": [],
}
if obj.type == 'MESH' and obj.data:
data["vertices"] = len(obj.data.vertices)
data["faces"] = len(obj.data.polygons)
data["materials"] = [slot.material.name for slot in obj.material_slots if slot.material]
if obj.type == 'LIGHT':
data["light_type"] = obj.data.type
data["energy"] = obj.data.energy
data["color"] = list(obj.data.color)
for mod in obj.modifiers:
if mod.type == 'ARRAY':
data.setdefault("modifiers", []).append({
"type": "ARRAY",
"count": mod.count,
"offset_object": mod.offset_object.name if mod.offset_object else None,
})
for child in obj.children:
data["children"].append(extract_hierarchy(child, depth + 1))
return data
scene_data = {
"name": bpy.context.scene.name,
"fps": bpy.context.scene.render.fps,
"frame_start": bpy.context.scene.frame_start,
"frame_end": bpy.context.scene.frame_end,
"objects": [],
}
for obj in bpy.context.scene.objects:
if obj.parent is None:
scene_data["objects"].append(extract_hierarchy(obj))
print(json.dumps(scene_data, indent=2))
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

blender-mcp is a skill published in the GitHub repository vladmdgolam/agent-skills (8 stars, last pushed 4d ago), licensed MIT. It adds 153 tokens to every session and 6,006 once invoked, about $0.0008 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
