Slowtime MCP Server: Secure Time-Based Operations with Timing Attack Protection and Timelock Encryption

Overview: What is Slowtime MCP Server?

The Slowtime MCP Server is an integration layer designed to secure time-based operations for AI applications, ensuring robust timing attack protection and secure timelock encryption. This server acts as a crucial component in the Model Context Protocol (MCP) ecosystem, facilitating seamless communication between AI clients like Claude Desktop, Continue, Cursors, and various data sources or tools.

🔧 Core Features & MCP Capabilities

Time Fuzzing & Security

The Slowtime MCP Server is equipped with advanced timing attack prevention mechanisms. It introduces time fuzzing by adding random delays (100-5000ms) to operations, which are then jittered into a more unpredictable pattern. Constant-time comparisons and timestamps further enhance security.

In the context of MCP integration, these features ensure that interactions between AI applications and data sources or tools are protected from timing attacks. This is particularly important for sensitive operations such as encryption, decryption, and interval management.

Timelock Encryption Flow

The server supports robust timelock encryption, which involves encrypting data using an interval duration. When an interval starts, a timelock ID is generated based on the remaining time in that interval (e.g., 25 minutes). Only after the interval expires can the original data be decrypted.

This flow is critical for MCP clients like Claude Desktop to ensure secure handling of data, especially during multi-step operations involving encryption and decryption. The timelock mechanism guarantees that encrypted data remains protected until the specified time window has elapsed.

Interval Management

The server manages intervals through a detailed state machine, allowing for interval creation, pause, and resume operations. This is essential for tasks requiring specific durations to be tracked and managed securely.

For MCP clients, this means robust management of timed operations can be achieved with minimal overhead, ensuring that AI applications remain functional even during periods of inactivity or maintenance.

⚙️ MCP Architecture & Protocol Implementation

The Slowtime MCP Server consists of four main components: TimeFuzz, TimeKeeper, TimeLock, and TimeVault. Each component plays a critical role in implementing the full suite of security measures and functionalities required by MCP clients.

1. TimeFuzz

• Provides timing attack protection:
  • Random duration fuzzing
  • Constant-time comparisons
  • Jittered timestamps
  • Random operation delays

These mechanisms ensure that any potential timing attacks are mitigated, enhancing the overall security of operations involving encryption and decryption.

2. TimeKeeper

• Manages intervals with the following operations:
  • Creation/pause/resume operations
  • Progress tracking
  • Automatic cleanup
  • Fuzzing integration

The TimeKeeper ensures that intervals are tracked accurately and efficiently, providing a reliable environment for timing-based operations without sacrificing performance.

3. TimeLock

• Handles encryption with the following features:
  • drand network integration
  • Interval-based decryption
  • Automatic cleanup
  • Secure random number generation

The TimeLock component is crucial for ensuring that data remains secure during intervals and can only be decrypted once the specified time has passed, creating a strong security barrier.

4. TimeVault

• Provides persistent storage and analytics:
  • DuckDB WASM-based storage
  • Historical tracking of encrypted data
  • Analytics and statistics
  • Query capabilities with filtering

The TimeVault enables robust data management by maintaining a detailed history and generating valuable insights through various querying and filtering mechanisms.

🚀 Getting Started with Installation

To set up the Slowtime MCP Server, you need to update your Claude Desktop configuration. Here’s how:

1. Open the claude_desktop_config.json file at /Users/yourUsername/Library/Application Support/Claude/.
2. Add or modify the "mcpServers" section as follows:

{
  "mcpServers": {
    "slowtime": {
      "command": "node",
      "args": ["/path/to/slowtime-mcp-server/build/index.js"]
    }
  }
}

Replace /<path>/ with the actual path to your Slowtime MCP Server installation.

💡 Key Use Cases in AI Workflows

Use Case 1: Secure Time-Limited Access for API Requests

In scenarios where secure access is required, such as managing API tokens with expiration times, the Slowtime MCP Server can enforce strict time constraints. For instance, an AI application could use intervals to request and manage API tokens, ensuring they are only valid during their respective lifespans.

Use Case 2: Controlled Access to Sensitive Data

Sensitive data stored in a cloud or local database can be encrypted using the TimeLock functionality provided by the Slowtime MCP Server. This ensures that data remains inaccessible until the specified interval has elapsed, providing an additional layer of security for critical operations.
