Blender Agent Bridge
Blender Agent Bridge is a Blender extension paired with a localhost MCP server that connects the open Blender scene to external AI agents such as Claude Desktop, Claude Code, Codex, Cursor, and other MCP-capable clients.
What It Does
- Scene-aware inspection — agents can read objects, materials, animation, rigs, cameras, nodes, render settings, and
.blendhealth without a chat app or model-provider key living inside Blender. - Visual evidence — viewport captures, playblasts, inspection renders, thumbnails, and render jobs give agents something concrete to review before changing the scene.
- Reversible edits — helper edits stay pending with visible Commit and Revert controls, and normal Blender undo still applies.
- Optional trusted Python — generated scripts are refused by default and only run when session trust is deliberately enabled, with runtime-only, visibly revocable permissions.
- Optional providers — Poly Haven, Sketchfab, Tripo, Meshy, local TripoSR, and self-hosted studio endpoints are all opt-in, with provider-specific consent and provenance.
Safety Model
The bridge is off by default and bound to 127.0.0.1. Connected agents do not receive blanket access: preview edits require explicit commit, project tools are restricted to the saved project directory, and credentials are redacted from responses. Hosted generation requires explicit spend approval in Blender.
Getting Started
Install the extension in Blender 4.2 or newer, press Start in the Agent Bridge sidebar tab, then use Copy MCP Config to generate the correct local configuration for your MCP client. The bundled extension ZIP already includes the MCP server, so no pip, uv, or uvx setup is required for the recommended mode.
