Vision Memory MCP Server

@putervision/vision-memory-mcp

@putervision/vision-memory-mcp is a zero-infrastructure, local-first Model Context Protocol (MCP) server and CLI tool that provides AI coding assistants (such as Cursor, Claude Code, Gemini, or Copilot) with visual state caching using perceptual hashing, local CLIP embeddings, and transition graphs to eliminate repetitive vision LLM calls.

⚡ Quick Start & Installation

Prerequisites: Node.js >= 18.18.0

1. Installation

# Global installation via npm
npm install -g @putervision/vision-memory-mcp

2. Workspace Initialization

Run init in your project root to scaffold database directories, .gitignore, .env, and IDE rules:

vision-memory-mcp init --yes

3. Basic MCP Client Setup

Add to your MCP client config (e.g. .cursor/mcp.json or .vscode/mcp.json):

{
  "mcpServers": {
    "vision-memory-mcp": {
      "command": "vision-memory-mcp",
      "args": ["run"]
    }
  }
}

Alternative Options & CLI Usage Examples

# Run stdio MCP server directly via binary (after global install)
vision-memory-mcp run

# Start server skipping heavy CLIP model downloads (air-gapped / offline mode)
vision-memory-mcp run --skip-model-load

# Re-initialize across all registered workspace projects
vision-memory-mcp init-global

# Health check dependencies, sharp bindings, and git safety
vision-memory-mcp doctor

# Run health diagnostics & aggregate metrics across all registered projects
vision-memory-mcp doctor-global

# Inspect stored visual states and metadata in terminal ASCII table
vision-memory-mcp inspect

# Register baseline design mockup contract (Visual SDD)
vision-memory-mcp spec set --name "Dashboard" --file ./dashboard-spec.png

# Save visual memory checkpoint snapshot
vision-memory-mcp snapshot save --name "v1.0-milestone"

# Ingest WebM / MP4 video recording into visual state memory timeline
vision-memory-mcp video ingest ./playwright-test.webm --category playwright_test

# Open interactive force-directed visual graph viewer in browser
vision-memory-mcp view

🌟 Key Highlights

• 👁️ Perceptual Visual Caching: Sub-5ms L1/L2 dHash zero-token fast-path layout recognition.
• 🎬 WebM & MP4 Video Ingestion: Digest E2E test recordings & screen captures into searchable keyframe visual states & state transition graphs.
• ⚡ 15 Core MCP Tools: High-coherence consolidated toolset covering perception, video memory, evidence packs, trajectory comparison, semantic retrieval, element grounding, visual SDD, snapshots, and unified context & metrics.
• 🔗 Dual-MCP Synergy & Immutable Evidence Packs: Deeply bridges @putervision/state-memory-mcp task DAGs with visual state memory, generating cryptographically hashable evidence packs for compliance and audit trails.
• 📉 Reduced Token Overhead: Caches UI states locally using dHash, local CLIP vector search, and accessibility trees to maximize vision token savings.
• 🚀 Sub-5ms Fast-Path Latency: Eliminates repetitive vision LLM API calls and avoids visual hallucination loops.
• 🎯 Element Grounding & Action Target Prediction: Maps screen elements to CSS selectors and coordinates for deterministic UI interaction.
• 🎨 Visual Spec-Driven Development (Visual SDD): Register design mockups or screenshots as perceptual baseline contracts to verify visual regression.
• 🛡️ 100% Local-First Privacy: Local LanceDB vector store, local CLIP model, zero cloud telemetry, and PII redaction guarantees.

🛠️ MCP Tool Suite

@putervision/vision-memory-mcp provides 15 production-grade consolidated MCP tools structured across 4 core visual perception & automation domains:

• Perception & Semantic Search: analyze_screenshot (L1/L2 perceptual dHash & AX tree parsing, single/batch), recall_memory (text & image semantic vector search), get_session_context (aggregated cache hit metrics, recent states).
• Element Grounding & Navigation: predict_next_action (deterministic CSS selectors & bounding coordinates), record_outcome (UI action transitions & visual blockers), get_navigation_paths (BFS shortest-path planner), wait_for_visual_state (polling for target UI state).
• Video Trajectories & Evidence Packs: manage_video (WebM/MP4 keyframe ingestion, timeline search), compare_states (visual layout diffs & video trajectory comparison), create_evidence_pack (cryptographic audit proof linking video keyframes to state-memory DAGs), export_trajectories (multimodal fine-tuning datasets).
• Snapshots & Visual SDD: manage_visual_spec (mockup baseline contracts & regression checks), manage_snapshot (checkpoints, export, restore), undo_visual_mutation (revert state ingestion), forget_state (privacy & PII purging).

⚠️ When Not to Use This Server

While vision-memory-mcp is designed for visual frontend state caching, UI testing, and multimodal workflows, it may not be appropriate for:

• Headless / Pure Backend Development: Non-visual CLI tools, database scripts, or pure backend microservices with no UI rendering. (Use state-memory-mcp standalone instead).
• High-Framerate Live Video Streaming: Continuous 60 fps live video ingest without discrete keyframe or test action boundaries.
• Ultra Low-Memory Embedded Environments (<512 MB RAM): Running full local CLIP neural embeddings requires ~300 MB RAM (use --skip-model-load for lightweight dHash-only perception if memory is constrained).

---

🧪 Testing

# Run full unit and integration test suite across all 69 test files (300 tests)
npm run test
