Supports reverse proxy configurations with Apache for routing traffic to the MCP memory server in secure deployment scenarios.
Provides containerized deployment of the MCP memory server, enabling easy setup and management with Docker images and containers.
Supports HTTPS connections and reverse proxy configurations with Nginx for secure and flexible deployment architectures.
Uses OpenAI's API for generating embeddings that power semantic search capabilities across the knowledge graph.
Used as the command shell for launching the server in local environments, as specified in the MCP settings configuration.
MCP Memory Server with Qdrant Persistence
This MCP server provides a knowledge graph implementation with semantic search capabilities powered by Qdrant vector database.
Features
Graph-based knowledge representation with entities and relations
File-based persistence (memory.json)
Semantic search using Qdrant vector database
OpenAI embeddings for semantic similarity
HTTPS support with reverse proxy compatibility
Docker support for easy deployment

Semantic Search
search_similar
: Search for semantically similar entities and relationsinterface SearchParams { query: string; // Search query text limit?: number; // Max results (default: 10) }
Implementation Details
The server maintains two forms of persistence:
File-based (memory.json):
Complete knowledge graph structure
Fast access to full graph
Used for graph operations
Qdrant Vector DB:
Semantic embeddings of entities and relations
Enables similarity search
Automatically synchronized with file storage
Synchronization
When entities or relations are modified:
Changes are written to memory.json
Embeddings are generated using OpenAI
Vectors are stored in Qdrant
Both storage systems remain consistent
Search Process
When searching:
Query text is converted to embedding
Qdrant performs similarity search
Results include both entities and relations
Results are ranked by semantic similarity
Example Usage
HTTPS and Reverse Proxy Configuration
The server supports connecting to Qdrant through HTTPS and reverse proxies. This is particularly useful when:
Running Qdrant behind a reverse proxy like Nginx or Apache
Using self-signed certificates
Requiring custom SSL/TLS configurations
Setting up with a Reverse Proxy
Configure your reverse proxy (example using Nginx):
Update your environment variables:
Security Considerations
The server implements robust HTTPS handling with:
Custom SSL/TLS configuration
Proper certificate verification options
Connection pooling and keepalive
Automatic retry with exponential backoff
Configurable timeouts
Troubleshooting HTTPS Connections
If you experience connection issues:
Verify your certificates:
Test direct connectivity:
Check for any proxy settings:

This server cannot be installed
remote-capable server
The server can be hosted and run remotely because it primarily relies on remote services or has no dependency on the local environment.
Facilitates knowledge graph representation with semantic search using Qdrant, supporting OpenAI embeddings for semantic similarity and robust HTTPS integration with file-based graph persistence.
