Installation

Add to your Claude Desktop config at ~/Library/Application Support/Claude/claude_desktop_config.json:

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

Usage

Basic Interval Commands

start_interval "Focus Time" 25  ───► [25min Interval Created]
                                          │
check_interval <id>  ◄───────────────────┘
                                          │
pause_interval <id>  ◄───────────────────┘
                                          │
resume_interval <id> ◄───────────────────┘

Timelock Encryption

1. Start Interval:
   "Focus Time" (25min) ──► [Interval ID: abc123]

2. Encrypt Data:
   "secret" + abc123 ──► [Timelock ID: xyz789]

3. Attempt Decrypt:
   - Before interval ends: "Not yet decryptable"
   - After interval ends: "secret"

Architecture

The server consists of four main components:

TimeFuzz: Provides timing attack protection through:
- Random duration fuzzing
- Constant-time comparisons
- Jittered timestamps
- Random operation delays
TimeKeeper: Manages intervals with:
- Creation/pause/resume operations
- Progress tracking
- Automatic cleanup
- Fuzzing integration
TimeLock: Handles encryption with:
- drand network integration
- Interval-based decryption
- Automatic cleanup
- Secure random number generation
TimeVault: Provides persistent storage and analytics:
- DuckDB WASM-based storage
- Historical tracking of encrypted data
- Analytics and statistics
- Query capabilities with filtering

TimeVault Commands

Query historical data and statistics about encrypted timevaults:

# List vault history with filtering
list_vault_history --interval_id=abc123 --decrypted_only=true --limit=10

# Get vault statistics
get_vault_stats

Example output:
Total vaults: 150
Decrypted vaults: 75
Average decryption time: 45 seconds

Storage Schema

The TimeVault uses DuckDB WASM for persistent storage with the following schema:

CREATE TABLE timevaults (
  id VARCHAR PRIMARY KEY,
  encrypted_data TEXT NOT NULL,
  round_number BIGINT NOT NULL,
  created_at TIMESTAMP NOT NULL,
  decrypted_at TIMESTAMP,
  interval_id VARCHAR NOT NULL,
  metadata JSON
);

-- Indexes for efficient querying
CREATE INDEX idx_interval_id ON timevaults(interval_id);
CREATE INDEX idx_created_at ON timevaults(created_at);
