Bi-Temporal Knowledge Graph MCP Server

A production-ready MCP (Model Context Protocol) server that combines a sophisticated bi-temporal knowledge graph with dynamic automation tool generation. Save facts with full temporal tracking, extract entities using AI, and generate custom automation tools on-the-fly from database configurations.

🎯 Build intelligent AI agents with persistent memory that understands time and context

Architecture

This server uses a modular architecture:

• main.py - The main orchestrator that initializes FastMCP, registers core memory tools, and manages the complete server lifecycle

• memory.py - Bi-temporal Graphiti memory implementation with FalkorDB for knowledge graph storage

• tools.py - Container for automation tools with webhook execution utilities

✨ Features

🧠 Bi-Temporal Knowledge Graph

• Smart Memory: Automatically tracks when facts were created AND when they became true in reality

• Conflict Resolution: When you move locations or change jobs, old facts are automatically invalidated

• Time Travel Queries: Ask "Where did John live in March 2024?" and get accurate historical answers

• Session Tracking: Maintains context across conversations with automatic cleanup

🤖 AI-Powered Entity Extraction

• Natural Language Understanding: Just tell it in plain English - "Alice moved to San Francisco and started working at Google"

• Automatic Relationship Discovery: AI extracts entities and relationships without manual input

• OpenAI Integration: Uses GPT-4 for intelligent entity extraction

• Graceful Degradation: Works without AI - just add facts manually

🚀 Quick Start

Option 1: Docker Compose (Recommended)

# 1. Download and extract
wget https://github.com/YOUR_USERNAME/bitemporal-mcp-server/archive/main.zip
unzip main.zip
cd bitemporal-mcp-server-main

# 2. Configure
echo "OPENAI_API_KEY=sk-your-key" > .env

# 3. Start everything (FalkorDB + MCP Server)
docker-compose up -d

# 4. Verify it's running
curl http://localhost:8080/health

That's it! 🎉 Your server is now running at http://localhost:8080/sse

Option 2: Python (Local Development)

# 1. Install dependencies
pip install -r requirements.txt

# 2. Configure
cp .env.example .env
# Edit .env with your settings

# 3. Start FalkorDB (Docker)

🛠️ Creating Automation Tools

Overview

The tool generator reads webhook configurations and automatically creates MCP tools. Here's how:

Step 1: Define Your Webhook in Automation Engine OS

1. Go to Automation Engine OS

2. Create a new webhook configuration

3. Define fields and parameters

4. Save your configuration

Step 2: Generate the MCP Tool

# Via MCP protocol or directly in Python
await generate_tool_from_db(
    user_id="your_user_id",
    item_name="Slack Notification",
    item_type="single"  # or "multi" for multiple webhooks
)

Step 3: Use Your New Tool

# Your tool is now available!
await slack_notification(
    message="Deployment completed!",
    channel="#devops"
)

Example: Single Webhook Tool

Database Configuration:

{
  "name": "Send Email",
  "url": "https://api.example.com/send-email",
  "template_fields": {
    "to": {"type": "str", "required": true},
    "subject": {"type": "str", "required": true},
    "body": {"type": "str", "required": true}
  }
}

Generated Tool:

@mcp.tool()
async def send_email(to: str, subject: str, body: str):
    """Send an email via webhook."""
    # Automatically generated code

Example: Multi-Webhook Tool (Parallel Execution)

Database Configuration:

{
  "name": "Broadcast Alert",
  "webhooks": [
    {"url": "https://hooks.slack.com/...", "data": {"message": "..."}},
    {"url": "https://discord.com/api/webhooks/...", "data": {"content": "..."}},
    {"url": "https://api.email.com/send", "data": {"subject": "..."}}
  ]
}

Result: All three webhooks fire simultaneously using asyncio.gather!

💡 Use Cases

Personal Knowledge Management

Track your life events, relationships, and locations with full history:

await add_message(
    "I met Sarah at the tech conference. She works at OpenAI.",
    session_id="my_life"
)
# Later: "Where did I meet Sarah?" → "At the tech conference"

Customer Relationship Management

Monitor customer interactions with automatic conflict resolution:

await add_fact("CustomerA", "status", "premium")
# Automatically invalidates previous "status" facts
# Query history: "What was CustomerA's status in January?"

AI Agent Memory

Give your AI agents persistent, queryable memory:

# Agent learns from conversation
await add_message(
    "User prefers morning meetings and uses Slack",
    session_id="agent_123"
)
# Agent recalls later: "What are the user's preferences?"

Workflow Automation

Combine knowledge with actions:

# When fact changes, trigger automation
if customer_upgraded_to_premium:
    await notify_sales_team(customer_name=name)
    await update_crm(customer_id=id, tier="premium")

❓ Frequently Asked Questions

Q: Does this require OpenAI?

A: No! OpenAI is optional for AI entity extraction. You can add facts manually without it.

Q: Can I use this with Claude Desktop?

A: Yes! Add the server URL to your claude_desktop_config.json:

{
  "mcpServers": {
    "knowledge-graph": {
      "url": "http://localhost:8080/sse"
    }
  }
}

Q: How do I query historical data?

A: Use the query_at_time tool:

await query_at_time(
    timestamp="2024-01-15T00:00:00Z",
    entity_name="John"
)

Q: Can I deploy this to production?

A: Absolutely! See DEPLOYMENT.md for guides on:

• Replit Autoscale

• Railway

• Render

• Fly.io

• Docker

• VPS

Q: How does fact invalidation work?

A: When you add a fact about location or employment, the system automatically finds previous facts of the same type and marks them as invalid_at: current_time. Your query results only show current facts unless you specifically request historical data.

Q: Can I create bulk download tools?

A: Yes! Create a multi-webhook template with multiple endpoints, and the tool generator will create a function that fires all webhooks in parallel.

Q: Is my data secure?

A: Yes! Everything runs in your infrastructure. No data is sent anywhere except:

• OpenAI (only if you use entity extraction)

• Your configured webhooks (only when you call them)

Q: How much does it cost to run?

A: Free for self-hosting! Only costs:

• FalkorDB hosting (free tier available)

• OpenAI API usage (optional, ~$0.001 per extraction)
