Blender MCP is a Model Context Protocol integration that bridges Claude directly to Blender, the open-source 3D creation suite. Through a local addon + MCP server, you can describe what you want in plain English—"add a metallic sphere with subsurface scattering", "position the camera for a dramatic product shot", "run this Python cleanup script"—and Claude executes it live inside Blender without you touching menus. The integration supports full object manipulation (create, modify, delete, transform), material assignment, scene querying, and even AI-generated 3D model imports via Hyper3D and Hunyuan3D. Version 1.5.5 includes a Blender-side addon panel for easy setup and one-click MCP server launching. Under the hood it's a JSON-RPC bridge over a local socket. Blender MCP has been gaining traction since late 2025 but spiked back onto GitHub trending today with 339 new stars—likely fueled by Claude's improved spatial reasoning in recent releases. For indie game devs, motion designers, and architects who live in Blender but dread its UI depth, this is a genuine workflow accelerant.

Pretty Fish is a free, open-source Mermaid diagram editor with live preview, 5 built-in themes, multi-page workspaces, and one-click SVG/PNG export. It works offline as a Progressive Web App (PWA) and requires no account, no login, and no installation. It supports all 14+ Mermaid diagram types including flowcharts, sequence diagrams, Gantt charts, entity-relationship diagrams, and Git graphs. The editor includes syntax highlighting, auto-completion, instant error feedback, and a clean split-pane layout. The multi-page workspace lets you manage entire diagram projects in a single session. Export quality is excellent — SVG output is clean and scaling-ready for use in presentations, docs, or design systems. Pretty Fish hit Hacker News front page today with 128 points and has the makings of the go-to Mermaid editor for developers who generate diagrams from AI-assisted documentation workflows. With LLMs increasingly generating Mermaid syntax in their outputs, having a polished renderer and editor matters more than ever.
Reviewer scorecard
“This is exactly the kind of MCP integration that makes the protocol click—real creative software with a complex API that's genuinely painful to navigate manually. The one-click addon install and local socket architecture means no cloud routing, no latency surprises. If you're already on Claude's API, this is a free superpower for your 3D work.”
“The official Mermaid live editor is clunky and slow. Pretty Fish loads instantly, works offline, and the multi-page workspace means I can manage all my architecture diagrams in one place. Bookmarking this immediately as my default Mermaid editor.”
“Blender's Python API is enormous—this MCP server exposes a useful subset but you'll hit its limits fast on anything beyond basic modeling. LLMs still hallucinate object names, wrong axis directions, and non-existent Blender API calls. For production pipelines, you're better off writing actual Python scripts than hoping Claude gets your scene graph right.”
“It's a genuinely nice editor but it's solving a niche problem — most devs who need Mermaid diagrams already use VS Code extensions or embed them in Notion. And with no backend, there's no collaboration or sharing story, which limits its use in team workflows.”
“The real story here is MCP becoming the universal controller layer for creative software. Blender today, Maya tomorrow, Unreal Engine next week. We're watching the birth of 'natural language DCC'—a whole category of tools where artists describe outcomes and AI handles the procedural execution layer that's always been the highest barrier to entry.”
“As AI tools increasingly output Mermaid syntax to explain architectures and flows, the need for a great rendering environment grows. Pretty Fish positions itself at the intersection of AI-generated diagrams and human editing — that's a well-timed niche.”
“As someone who uses Blender weekly but has never fully mastered its node systems, this is genuinely exciting. Asking Claude to 'set up a three-point lighting rig for a product shot' instead of hunting through menus shaves real minutes off every session. The Hyper3D import feature alone could replace hours of low-poly asset modeling.”
“Five beautiful themes and clean SVG exports mean I can finally use Mermaid diagrams in client-facing presentations without them looking like developer scratch notes. This is the Mermaid editor I've always wanted and the zero-friction setup seals it.”
