Category: Search & AI memory

Install

Pick the AI app you use, then copy the settings.

Before you install

Basic checks: 1 of 1 passed
Runs on your computer with your user’s permissions (files, network, apps).
The registry lists no key to fill in.

You need

npmNode.js installed (for the npx command)

Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "state-memory": {
      "command": "npx",
      "args": [
        "-y",
        "@putervision/state-memory-mcp"
      ]
    }
  }
}

Run this in your terminal

claude mcp add state-memory -- npx -y @putervision/state-memory-mcp

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "state-memory": {
      "command": "npx",
      "args": [
        "-y",
        "@putervision/state-memory-mcp"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "state-memory": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@putervision/state-memory-mcp"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Common questions

Is State Memory MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.4.1) reached the registry 34 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

@putervision/state-memory-mcp

@putervision/state-memory-mcp is a zero-infrastructure, deterministic Model Context Protocol (MCP) server that provides AI coding assistants (such as Cursor, Claude Code, Gemini, or Copilot) with a structured, persistent SQLite graph for tracking workflow state—tasks, decisions, artifacts, plans, blockers, and their semantic relationships.

🌐 Official Documentation & Website: statememorymcp.com

⚡ Quick Start & Installation

Prerequisites: Node.js >= 18.18.0

# 1. Install globally

npm install -g @putervision/state-memory-mcp

2. Navigate to your project directory

cd your-project

3. Initialize state-memory-mcp

Creates .state-memory-mcp/, updates .gitignore, registers project,

and scaffolds IDE instructions and MCP configs for Cursor, Claude, VS Code, Windsurf, etc.

state-memory-mcp init

Done! Restart your IDE or Agent Manager to activate.

Alternative Options

# Run directly via binary (after global install)

state-memory-mcp run

Re-initialize across all registered workspace projects

state-memory-mcp init-global

🌟 Key Highlights

🧠 Deterministic State Memory & Compact TaskSlices: Zero LLM in the loop for memory operations; fast, deterministic SQLite graph traversals, and sub-1KB TaskSlice extraction for System 1 fast path evaluation.
⚡ 13 Production-Grade Consolidated MCP Tools: Full CRUD, relationship linking, DAG cycle checks, FTS5 search, TF-IDF RAG, time-travel history rollback, Spec-Driven Development, and auto-healing validation.
📉 Efficient Context Management & Decision Thresholding: Offloads context to a local SQLite database, filters sub-0.70 routine decisions to append-only event logs to prevent graph bloat, and preserves high-significance turns.
🚀 67%–74% Latency Reduction: Eliminates multi-step file scanning loops; agents retrieve unblocked tasks and blockers in milliseconds.
🤝 Multi-Agent Blackboard: Shared Context Store allowing parallel subagents to publish decisions, tasks, and blocker updates safely.
🎨 Interactive 3D Visualizer: Browser-based dark-mode 3D WebGL force-directed graph visualizer (state-memory-mcp view).
🔗 Dual-MCP Synergy: Pair with @putervision/vision-memory-mcp for visual state caching, perceptual hashing, and cryptographic multimodal evidence packs.
🛡️ 100% Local & Private: Local-first architecture; all state stays inside .state-memory-mcp/ in your workspace.

🛠️ MCP Tool Suite

@putervision/state-memory-mcp provides 13 production-grade consolidated MCP tools organized across 5 core workflow domains:

Graph & Relationships: manage_nodes (node CRUD, FTS5/TF-IDF vector search, atomic batch mutations, observation notes, thresholded fast decision logging), manage_edges (typed DAG links, multimodal visual state linking).
Task Execution & Work Queue: manage_tasks (topological dependency queue, blocker detection, task completion with artifacts, auto-prune), manage_sessions (agent attribution, turn tracking, context bootstrap).
Spec-Driven Development (SDD): manage_specs (PRD/RFC parsing, requirement-to-task decomposition, live acceptance criteria verification, compliance scoring).
Analytics, Audit & Diagnostics: get_analytics (velocity, burndown, token ROI, cognitive load, critical path), get_events (SHA-256 tamper-evident event ledger), run_diagnostics (DAG validation, health checks, AST reference integrity).
Data, Snapshots & Multi-Agent: manage_snapshots (checkpoints, time-travel undo), manage_database (backups, checksum audits, VCS branch merge), manage_data (bulk import/export, ML trajectories with interleaved fast decision events), query_graph (subgraphs, dependency tracing, raw SQL, sub-1KB compact_slice), use_blackboard (multi-agent asynchronous topic board).

👉 For complete parameter specifications, return schemas, and example payloads, see the [Tools Reference Guide](docs/tools-reference.md) and [Formal API Reference](docs/api-reference.md).
