totalreclaw 1.8.2

End-to-end encrypted memory for AI agents — Python client

totalreclaw

End-to-end encrypted memory for AI agents -- the "password manager for AI memory."

Store, search, and recall memories across any AI agent with zero-knowledge encryption. Your data is encrypted on-device before it leaves -- the server never sees plaintext.

Features

• End-to-end encrypted -- XChaCha20-Poly1305 encryption, HKDF key derivation from BIP-39 mnemonic
• Portable -- Same recovery phrase works across Hermes, OpenClaw, Claude Desktop, IronClaw
• Local embeddings -- Harrier-OSS-v1-270M runs on-device (no API calls)
• Hybrid search -- BM25 + cosine similarity + RRF reranking
• LSH bucketing -- Locality-sensitive hashing for encrypted search
• On-chain storage -- Managed service stores on Gnosis/Base Sepolia via ERC-4337

Quick Start

pip install totalreclaw

Docker users: On slim images (e.g., python:3.12-slim), install a C compiler first for PyStemmer:

apt-get update && apt-get install -y gcc g++

import asyncio
from totalreclaw import TotalReclaw

async def main():
    client = TotalReclaw(
        recovery_phrase="your twelve word recovery phrase here",
        server_url="https://api.totalreclaw.xyz",  # default, can be omitted
    )

    # REQUIRED: resolve Smart Account address and register with relay
    await client.resolve_address()
    await client.register()

    # Store a memory (importance is a float from 0.0 to 1.0)
    fact_id = await client.remember("Pedro prefers dark mode for all editors", importance=0.8)

    # Search memories
    results = await client.recall("What does Pedro prefer?")
    for r in results:
        print(f"  [{r.rrf_score:.3f}] {r.text}")

    # Delete a memory
    await client.forget(fact_id)

    # Export all memories
    facts = await client.export_all()

    # Check billing
    status = await client.status()
    print(f"Tier: {status.tier}, Used: {status.free_writes_used}/{status.free_writes_limit}")

    await client.close()

asyncio.run(main())

Important: You must call resolve_address() and register() before any operations. resolve_address() derives the CREATE2 Smart Account address via an RPC call, and register() authenticates with the relay.

With Embeddings (Recommended)

For semantic search, install with embedding support:

pip install totalreclaw

from totalreclaw import TotalReclaw
from totalreclaw.embedding import get_embedding

client = TotalReclaw(recovery_phrase="...")

# Store with embedding for semantic search
text = "Pedro prefers dark mode"
embedding = get_embedding(text)
await client.remember(text, embedding=embedding)

# Search with embedding
query = "What are Pedro's UI preferences?"
query_emb = get_embedding(query)
results = await client.recall(query, query_embedding=query_emb)

The embedding model (~600 MB) downloads automatically on first use.

Hermes Agent Plugin

pip install totalreclaw[hermes]

The plugin registers automatically with Hermes Agent v0.5.0+. See the Hermes setup guide.

Architecture

Plaintext → XChaCha20-Poly1305 encrypt → Blind indices (SHA-256) → LSH buckets → On-chain via relay
                                                                              ↓
Query → Blind trapdoors → GraphQL search → Decrypt candidates → BM25+Cosine+RRF rerank → Top 8

All encryption happens client-side. The relay server and on-chain storage never see plaintext.

Cross-Language Parity

This Python client produces byte-for-byte identical outputs to the TypeScript implementation (@totalreclaw/mcp-server):

• Key derivation (HKDF-SHA256)
• XChaCha20-Poly1305 wire format (nonce || tag || ciphertext)
• Blind indices (SHA-256 + Porter stemming)
• Content fingerprints (HMAC-SHA256)
• LSH bucket hashes (32-bit x 20 tables)

Memories stored by the Python client can be recalled by the MCP server, and vice versa.
