What to compare
- publisher and official or community status
- code execution and file access
- external services and telemetry
- maintenance activity and supported versions
- isolation required before first use
Read the sources
Blender Lab MCP Server ↗
Blender Lab's MCP server and add-on, which give an MCP client a natural-language interface to a Blender session through Blender's Python API.
Requires Blender 5.1 or newer, the add-on, an MCP client and the server. Blender warns that it runs model-generated code without guards and recommends a virtual machine or a system without sensitive data. An official origin does not make generated code safe. Keep private files and credentials out of reach of the Blender session.
MCP for Blender (community project) ↗
A widely used community MCP server and Blender add-on, not affiliated with the Blender Foundation. Its tools run arbitrary Python in Blender and fetch assets from external services.
Third-party code that Baltor has not reviewed. Its README says a minimal anonymous usage record is sent by default and documents how to turn telemetry off. MIT-licensed code. Fetched assets keep their providers' terms, and several services need their own API keys or a paid plan.
Godot MCP (community project) ↗
A widely used community MCP server for Godot, published outside the Godot project, that launches the editor, runs projects, captures debug output and edits scenes.
Third-party code that Baltor has not reviewed. Its example client setup pre-approves tools that run projects and save scenes; review that list before use. MIT-licensed. Check recent repository activity and test against the Godot version in use before relying on it.
MCP security best practices ↗
The protocol project's guidance on attacks and mitigations for MCP clients and servers, including local server compromise, token passthrough and server-side request forgery.
Public documentation. This address follows the latest specification revision; earlier revisions have dated pages. Guidance is not an audit. Apply it to the exact server, transport and client configuration in use.
Official MCP Registry ↗
Server metadata and discovery documentation for MCP-compatible tools and services.
Use the registry's documented read API and publisher references; discovery does not authorize a server connection. Registry inclusion does not certify safety, uptime or licence compatibility. Review each server and requested scope.
When to look again
Before enabling a server, after a server or protocol update, and before the project handles private files.

Compare the named servers for the creative task. Show which tools can run code, write files or reach external services, and recommend an isolated setup such as a virtual machine. Do not install, connect or pre-approve tools.
