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.

Mnemos
Local vector memory for Claude Desktop with 3D conversation visualization

Claude Desktop has no memory across sessions. You close the window and it forgets everything. Mnemos is an open-source MCP server that fixes this by watching your conversation files in real-time, indexing them with local ONNX embeddings (MiniLM-L6-v2), and enabling hybrid semantic + keyword search — all without a single byte leaving your machine. The v1.1 release adds a genuinely striking feature: a 3D semantic visualization that maps your conversations into a clustered constellation using UMAP dimensionality reduction and Three.js. You can scrub through a chronological timeline and watch the knowledge graph build in real time. It is, frankly, prettier than it needs to be. Built on .NET 9, SQLite FTS5, and React/Vite, Mnemos is one of the more technically ambitious "Claude memory" projects to appear on HN this week. The offline-first, MIT-licensed approach puts it in a different league from cloud-synced alternatives.
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.”
“This solves a real, painful problem with zero cloud dependency. The hybrid FTS5 + vector search is the right architecture — you get speed and semantic richness without compromising privacy. The .NET 9 stack is slightly niche but the setup looks smooth.”
“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 is a one-person Show HN project posted literally today with 2 GitHub stars. The 3D visualization is cool but has nothing to do with actually improving recall quality. Also: how often do you actually need to search old Claude conversations vs. just starting fresh?”
“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.”
“Local-first AI memory is the correct long-term architecture. Every AI system we rely on should have this kind of persistent, private, searchable context layer. Mnemos is a prototype of what OS-level AI memory will eventually look like, and seeing it built today matters.”
“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.”
“The 3D constellation visualization genuinely excites me — there is art in watching your conversation history render as a navigable space. For writers and researchers who use Claude heavily, the ability to rediscover old threads through semantic search could unlock something meaningful.”
