🧠 Holographic Memory — MCP Server (Go)
🌐 Website: holo.ai3d.art · Live (GitHub Pages): neo37.github.io/holographic-memory · Open-source · Privacy-first · $5/mo cloud
The first fully open-source, privacy-first holographic long-term memory for AI agents. Built on Kanerva's Sparse Distributed Memory (SDM) — the associative memory that recent research (2021–2026) proved to be mathematically equivalent to the Attention mechanism inside Transformers (GPT-4, Claude).
Give Claude Desktop, Cursor and any MCP-compatible agent a memory that thinks by association, not by keyword match. Say "I don't like Python" today, ask "what should I write this script in?" next month — and the agent recalls "Go, because you don't like Python." Plain vector RAG can't do that. Interference-based recall can.

1. Why Holographic Memory
Classic RAG is literal: no keyword overlap → no hit. SDM stores every fact as a
high-dimensional binary vector ({0,1}ⁿ, n ≈ 10 000) smeared across many addresses.
Recall reconstructs the signal by majority vote over everything inside the activation radius,
so it survives noise, partial cues and vague prompts — and it surfaces connections the user
only hinted at.
| Vector RAG | Holographic Memory (SDM) | |
|---|---|---|
| Match model | keyword / cosine similarity | associative interference |
| Vague query | misses | reconstructs from noise |
| Conflicting facts | silently coexist | flagged as interference |
| Foundation | ad-hoc embeddings | Kanerva SDM ≈ Transformer Attention |
2. How It Works
flowchart LR
A["Fact:<br/>'User dislikes Python'"] -->|encode| B["Hypervector<br/>{0,1}^10000"]
B -->|"write into radius r"| C[(Distributed<br/>address cloud)]
Q["Vague query:<br/>'what language?'"] -->|encode| D["Query vector"]
D -->|"activate within r"| C
C -->|"majority-rule read"| E["De-noised recall:<br/>'Use Go — you dislike Python'"]
A fact is not stored in one row — it is superposed across every hard location within a Hamming radius. Reading a noisy or vague cue re-collects those overlapping traces and votes them back into a clean answer.
3. The Math
Implemented in Go, straight from Kanerva's SDM:
- Distance — Hamming:
d(A, B) = Σᵢ (Aᵢ ⊕ Bᵢ) - Write — interference: activate every hard location within radius
rof addressX, then increment/decrement their counters (wave superposition):Activate(X) = { Y ∈ HardLocations | d(X, Y) ≤ r } - Read — associative recall: sum activated cells around query
Q, apply the majority rule:Outputᵢ = sign( Σ_{Y ∈ Activate(Q)} CellContents(Y)ᵢ )
This reconstructs a 100%-clean context even from a noisy or partially forgotten query.
4. MCP Tools
| Tool | What it does |
|---|---|
store_holographic_snapshot |
Store a structured memory (fact + context + emotional valence + importance + tags) as a superposed hypervector. |
recall_by_association |
Retrieve a de-noised "meaning cloud" from a vague or emotional cue. |
interference_analysis |
Detect when a new fact collides with an existing belief; return the conflict + confidence. |
consolidate_and_prune |
"Sleep": drop weak associations, reinforce frequently used ones, keep the store fast. |

Free --> Pro --> Biz
- Local (Free) — runs 100% on your machine; your memories never leave your computer.
- Cloud / Pro ($5/mo) — same memory in Claude at work and Cursor at home; managed, backed up, and visualized.
- Business — closed-source embedding rights + bespoke integrations.
7. Install
# One command via Smithery
npx -y @smithery/cli install holographic-memory
Or add it manually to claude_desktop_config.json:
{
"mcpServers": {
"holographic-memory": {
"command": "uvx",
"args": ["holographic-memory-server"],
"env": {
"MEMORY_MODE": "LOCAL",
"MEMORY_LICENSE_KEY": "optional — only for Cloud/Pro sync"
}
}
}
}
MEMORY_MODE=LOCAL needs no key and is free forever. Set a MEMORY_LICENSE_KEY (get one at
holo.ai3d.art) only to unlock encrypted cross-device sync.
