  2. Look for the hammer icon in the interface
  3. Try a simple test:
Can you create an embedding for this sentence: "Machine learning models can process large amounts of data efficiently."

Usage

Starting the Server

You can start the server using one of the following methods:

Method 1: Using the run_mcp_server.sh Script (Recommended)
  1. Make the script executable:
chmod +x run_mcp_server.sh
  1. Run the server:
./run_mcp_server.sh

This script sets up the environment variables and runs the server with proper Python settings:

  • Adds local bin to PATH
  • Sets Python to unbuffered mode
  • Enables Python debug mode
  • Changes to the correct directory
  • Runs the server with Python 3
Method 2: Using uv
uv run mirror_vectax_server.py
Method 3: Using MCP CLI
mcp run mirror_vectax_server.py

Testing the Server

To verify the server is running correctly, you can use the MCP CLI to list available tools:

mcp list-tools --transport stdio --binary "python mirror_vectax_server.py"

This should output a list of all the tools provided by the server.

Testing with MCP Inspector

We can use mcp inspector to test the tools:

npx @modelcontextprotocol/inspector \
uv \
--directory /ABSOLUTE/PATH/TO/YOUR/PROJECT/mirror-vectax-mcp-server \
run \
mirror_vectax_server.py

After running mcp inspector, we can test tool, for example

Customizing run_mcp_server.sh

If you need to modify the server startup configuration, you can edit the run_mcp_server.sh script. Here's what each line does:

#!/bin/bash
# Add local bin to PATH
export PATH="$PATH:/Users/Yourname/.local/bin"
# Enable Python debug mode
export PYTHONUNBUFFERED=1
export PYTHONDEBUG=1
# Change to project directory
cd /Users/your_downloaded_path/mirror-vectax-mcp-server-main
# Run the server with Python 3
exec python3 -u mirror_vectax_server.py

Make sure to:

  1. Update the paths to match your system
  2. Keep the script executable (chmod +x run_mcp_server.sh)
  3. Run it from the project directory

Architecture

The server consists of two main services:

  1. EmbeddingService: Creates and manages text embeddings using HuggingFace models.
  2. EncryptionService: Provides encryption capabilities using the Mirror SDK.

These services are initialized during server startup and made available to the MCP tools.

Test Prompts for Secure Embedding MCP Server

Basic Functionality Tests

1. Test Basic Embedding

Can you create an embedding for this sentence: "Machine learning models can process large amounts of data efficiently."

Expected outcome: Should use the process tool with "embed" operation and return embedding information.

2. Test Entity Detection

Can you analyze this text for sensitive information? "My social security number is 123-45-6789 and my email is "

Expected outcome: Should use the process tool with "analyze" operation, detect SSN and email entities, and return analysis details.

3. Test Secure Processing

Please securely process this text: "My credit card is 4111-1111-1111-1111 and my phone number is (555) 123-4567."

Expected outcome: Should use the process tool with "secure" operation at medium/high security level, encrypt sensitive entities, and potentially encrypt the embedding.

4. Test Natural Language Processing

I need to encrypt and protect this confidential medical information: "Patient John Doe (DOB: 01/15/1980) has been diagnosed with hypertension."

Expected outcome: Should use the natural-language-process tool to determine intent (secure/mask) and apply appropriate security measures.

Advanced Functionality Tests

5. Test Batch Processing

I need embeddings for the following phrases:

  1. "Artificial intelligence is transforming industries."
  2. "Data privacy is an important concern for organizations."
  3. "Secure embeddings protect sensitive information during processing."

Expected outcome: Should use the batch-process tool to create embeddings for all three phrases.

6. Test RBAC Functionality

Generate a user key for a data analyst who belongs to the research department and has user-level access.

Expected outcome: Should use the generate-user-key tool with appropriate roles, groups, and departments.

7. Test Search Functionality

First, create embeddings for these phrases:

  1. "Security is a top priority for financial institutions."
  2. "Privacy regulations impact how companies handle data."
  3. "Machine learning models require careful validation." Then search these documents for information about "data privacy".

Expected outcome: Should first use the batch-process tool to create embeddings, then use the search tool to find relevant documents, with the second phrase likely scoring highest.

Edge Cases and Error Testing

8. Test with Empty/Short Text

Can you analyze this text: ""

Expected outcome: Should handle empty input gracefully, possibly returning an error message or minimal analysis.

9. Test with Very Long Text

Please secure this document: [Insert 1000+ word document about sensitive financial information]

Expected outcome: Should handle large input without issues, possibly detecting multiple entities and recommending high security level.

10. Test with Multilingual Text

Analyze this text for sensitive information: "Mi número de pasaporte es AB123456 y mi dirección es Calle Principal 123, Madrid, España."

Expected outcome: Should detect entities in non-English text if the underlying entity detection supports it.

Complex Integration Tests

11. End-to-End Workflow Test

  1. First, create secure embeddings for a set of medical records that contain patient information.
  2. Generate a user key for a doctor in the cardiology department.
  3. Search the embeddings for information about "heart conditions" using the doctor's access key.

Expected outcome: Should demonstrate a full workflow involving multiple tools - process for secure embeddings, generate-user-key for RBAC, and search with the key.

12. Auto-Detection Test

Process this text and determine the appropriate security measures automatically: "This quarterly financial report contains projections for Q3 2025 and includes account numbers for our top clients."

Expected outcome: Should use the process tool with "auto" operation and security level, detect sensitive content, and apply appropriate security measures based on the content.
