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);
