Server Configuration
Describes the environment variables required to run the server.
| Name | Required | Description | Default |
|---|---|---|---|
| BLENDER_MCP_TOKEN | No | Optional token that must match the token configured in the Blender add-on preferences. Required only if the add-on has a token set. | |
| BLENDER_MCP_WORKSPACE_ROOTS | No | Semicolon-separated list of allowed workspace root paths. Restricts file access for import/export operations. |
Instructions
Guidance the server publishes about itself, which clients place ahead of the tool catalog so the model reads it before choosing anything.
This server publishes no instructions, or was last inspected before Glama recorded them.

Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| blender_statusA | Check whether the local Blender add-on bridge is running and report its capabilities. |
| blender_scene_summaryA | Summarize the open Blender file, object counts, armatures, meshes, actions, and save state. |

TDQS
Scored across 9 tools
Each tool targets a distinct stage or aspect of the character pipeline: status, scene info, object listing, import, creation, validation, normalization, action renaming, and export. There is no meaningful overlap between tool purposes, and descriptions clearly distinguish read-only actions from mutating ones.
All tools share the 'blender_' prefix and use snake_case, with most following a verb_noun pattern (import_asset, list_objects, validate_character). The exceptions are blender_status and blender_scene_summary, which use noun-only or noun_noun naming, creating a minor inconsistency.
With 9 tools, the set is well-scoped for the stated domain of Blender character preparation and export. Each tool covers a necessary step without redundant or excessive additions, fitting comfortably within the ideal 3-15 range.
The toolset covers the core lifecycle for character assets: import, create, validate, normalize, rename actions, and export. Minor gaps exist (e.g., no tool for direct editing of meshes or armatures), but the provided suite is sufficient for a complete character pipeline from import to game-ready export.
