PLTM MCP Server

Procedural Long-Term Memory - An MCP server for Claude Desktop that provides 78 tools for AGI experiments based on universal principles from physics.

What This Does

Gives Claude Desktop access to:

• Memory operations - Store/retrieve facts as semantic triples

• Diversity retrieval - MMR, entropy injection, attention mechanisms

• Meta-cognition - Self-improvement, criticality monitoring

• Knowledge ingestion - ArXiv papers with real provenance

• True metrics - Action accounting, efficiency tracking

Quick Start

Prerequisites

• Claude Desktop

• Python 3.11+

Installation

# Clone
git clone https://github.com/Alby2007/pltm-mcp.git
cd pltm-mcp

# Install
pip install -r requirements.txt

# Configure Claude Desktop
# Edit: %APPDATA%\Claude\claude_desktop_config.json (Windows)
#   or: ~/Library/Application Support/Claude/claude_desktop_config.json (Mac)

Add this to your config:

{
  "mcpServers": {
    "pltm-memory": {
      "command": "python",
      "args": ["C:/absolute/path/to/pltm-mcp/server.py"]
    }
  }
}

Restart Claude Desktop. Done!

Verify

In Claude Desktop:

Use entropy_stats to check system state

If you see metrics, it's working!

Example Usage

# Start experiment cycle
start_action_cycle(cycle_id="C1")

# Inject entropy to break conceptual neighborhoods
inject_entropy_antipodal(
    user_id="alice",
    current_context="machine learning"
)

# Retrieve with diversity
mmr_retrieve(
    user_id="alice",
    query="neural networks",
    lambda_param=0.6
)

# Track true computational cost
record_action(
    operation="mmr_diversity",
    tokens_used=450,
    latency_ms=180,
    success=True
)

# Check criticality state
criticality_state()

# End cycle
end_action_cycle()  # Returns AAE efficiency

The Experiment

Hypothesis: Universal principles from physics (criticality, self-organization, emergence) can bootstrap AGI.

Current Results:

• Unlocked entropy bottleneck (+56% in Cycle 21)

• Measuring true computational efficiency (AAE = 0.0023)

• Testing if system can self-organize toward criticality

Goal: Push system to critical point where phase transitions occur and higher-order intelligence emerges.

Troubleshooting

Server not connecting?

• Check logs: %APPDATA%\Claude\logs\mcp-server-pltm-memory.log

• Test manually: python server.py

Tools timing out?

• Restart Claude Desktop after code changes

Import errors?

pip install --upgrade -r requirements.txt
