dcc-mcp-blender: Instructions file for Codex

AGENTS.md

dcc-mcp-blender AGENTS.md is an instructions file for Codex, OpenCode from dcc-mcp/dcc-mcp-blender. It costs 1,555 tokens per session, scanned A, original, MIT.

Agent instructions for using Blender through dcc-mcp, a service that lets AI agents search for and call Blender operations.

In plain words
What is it for?
They cover the dcc-mcp command-line workflow, the Blender MCP server, available instances and types, and how to check or apply CLI updates.
Why use it?
They give agents a defined route for finding tools, checking their details, and calling them without relying on undocumented local controls.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions CLAUDE.md; mentions AGENTS.md; mentions Gemini CLI.

This is dcc-mcp/dcc-mcp-blender's own configuration. It tells Codex and OpenCode how to work on dcc-mcp-blender itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything dcc-mcp-blender configures →

Token cost

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.

Security

Grade A, and why

dcc-mcp-blender AGENTS.md 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 8d 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.

AGENTS.md — dcc-mcp-blender Agent Navigation Map

Progressive disclosure: this file is a map, not an encyclopedia. Follow the links for depth. Stay here for breadth.

Agent Control Path

AI agent runtimes default to the shared gateway through the dcc-mcp skill and dcc-mcp-cli REST commands:

dcc-mcp-cli search --query "<task>" --dcc-type blender
dcc-mcp-cli describe <tool-slug>
dcc-mcp-cli call <tool-slug> --json '{"key":"value"}'

Use dcc-mcp-cli list for live instances and dcc-mcp-cli dcc-types for release-catalog support. IDE users may continue to configure the gateway MCP endpoint; adapter-local Python start APIs are for host bootstrap and tests.

CLI availability and updates

If dcc-mcp-cli is missing, obtain user consent before using the official install commands in the README Agent workflow. Keep an official build current with:

dcc-mcp-cli update check
dcc-mcp-cli update apply

update apply stages the latest CLI for the next launch; it does not replace a running server.


30-Second Summary

dcc-mcp-blender embeds a standards-compliant MCP Streamable HTTP server directly inside Blender. It exposes 200+ Blender operations as MCP tools that any AI agent (Claude, Gemini, Cursor, etc.) can call over HTTP — no external gateway, no subprocess bridge.

Current version: 0.1.20 Core dependency: dcc-mcp-core>=0.20.0,<1.0.0 Python: 3.10+ (bundled with Blender) Blender: 3.6 LTS, 4.2 LTS, 4.3, 4.4


Quick Start (3 Lines)

import dcc_mcp_blender
handle = dcc_mcp_blender.start_server()
# MCP client connects through http://127.0.0.1:9765/mcp

Or install the Blender extension (ZIP) and the server starts automatically.

Goal: Install, configure, and connect an MCP host.

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.
