Mnemosyne

Memory and knowledge for your Kubernetes clusters

Mnemosyne is a Model Context Protocol (MCP) server that gives AI assistants deep visibility into Kubernetes clusters. Named after the Greek goddess of memory, Mnemosyne remembers and recalls everything about your cluster state, making Kubernetes operations accessible through natural language.

What Mnemosyne Remembers

• Pod Lifecycles: Track pod status, restarts, and resource usage across namespaces

• Service Topology: Understand service relationships and network connectivity

• Application Context: Extract service descriptions and documentation from running pods

• Cluster Health: Monitor node status and resource allocation

• Operational History: Access logs and events with intelligent filtering

Related MCP server: Kubectl MCP Tool

Key Features

• Natural Language Interface: Ask questions like "What pods are failing?" or "Show me the logs for the auth service"

• Intelligent Service Discovery: Automatically finds and describes services using embedded documentation

• Multi-Protocol Support: WebSocket and HTTP endpoints for flexible integration

• Production Hardened: RBAC, health checks, structured logging, and security best practices

• Zero-Config Deployment: Works out of the box with sensible defaults

Quick Start

1. Deploy to Kubernetes

# Quick deployment for development
./scripts/quick-deploy.sh

# Production deployment
IMAGE_TAG=v1.0.0 NAMESPACE=production ./scripts/build-and-deploy.sh

2. Connect Your AI Assistant

Add Mnemosyne to your AI assistant's MCP configuration:

{
  "mcpServers": {
    "mnemosyne": {
      "command": "websocket", 
      "args": ["ws://localhost:8080/ws"],
      "disabled": false,
      "autoApprove": ["list_pods", "get_pod_logs", "describe_service"]
    }
  }
}

3. Start Asking Questions

Now you can ask your AI assistant natural language questions about your cluster:

• "What pods are running in the production namespace?"

• "Show me the logs for the failing authentication service"

• "What's the resource usage of the database pods?"

• "Describe the user-service and its dependencies"

• "Which nodes are under pressure?"

Mnemosyne translates these questions into the appropriate Kubernetes operations and returns human-readable results.

Mnemosyne's Capabilities

Special Feature: Service Documentation Discovery

Mnemosyne automatically looks for /mnemosyne/serviceDescription.txt files in your pods to provide rich context about your services. This makes troubleshooting and understanding service relationships much more intuitive.

┌─────────────────┐    ┌──────────────────┐    ┌─────────────────┐

Mnemosyne acts as the memory layer between AI assistants and Kubernetes:

• Memory Layer: Remembers cluster state, relationships, and context

• Translation Layer: Converts natural language to kubectl operations

• Intelligence Layer: Enriches raw Kubernetes data with meaningful insights

• Protocol Layer: Speaks MCP to AI assistants and kubectl to clusters

Development

Local Development

# Setup development environment
./scripts/local-dev.sh setup

# Run locally

Troubleshooting

Common Issues

1. Pod not starting: Check image availability and resource limits

2. kubectl errors: Verify RBAC permissions and kubeconfig

3. Connection issues: Check service/ingress configuration and CORS

4. Performance: Monitor resource usage and optimize queries

Debug Mode

Enable debug logging:

kubectl set env deployment/mnemosyne DEBUG=true -n mcp-server

Why Mnemosyne?

In Greek mythology, Mnemosyne was the goddess of memory and the mother of the nine Muses. She gave mortals the ability to remember and learn from experience.

Similarly, this Mnemosyne gives AI assistants the ability to remember and understand your Kubernetes clusters, transforming raw operational data into actionable insights.
