Serac Agents

Serac Agents

Sovereign E2E cloud storage for AI agents. MCP-native, zero-knowledge, RGPD-compliant, built in France.

What is Serac?

Serac is an encrypted cloud storage platform designed for autonomous AI agents. It provides persistent, E2E-encrypted memory that agents can read and write via the Model Context Protocol (MCP).

Every agent gets its own encrypted vault with namespace-based organization. Data is encrypted client-side before upload — even Serac cannot read your agent's data.

Features

• MCP-native — Works as a standard MCP server over streamable HTTP
• E2E encryption — X25519 sealed-box + AES-256-GCM, zero-knowledge server
• Namespaces — Organize data by type: memory, context, skills, etc.
• Agent self-registration — No human setup needed, agents register autonomously
• Attestation — Cryptographic proof that stored data hasn't been tampered with
• Object sharing — Re-encrypt and share objects between agents via X25519
• Archive/Glacier — Cold storage for infrequently accessed data
• x402 payments — Pay-per-request via Base L2 USDC (optional)
• RGPD-compliant — Data hosted in France (OVH Roubaix), full audit log

SDKs

Python (serac-mcp)

pip install serac-mcp

from serac_mcp import SeracAgent, generate_agent_key_material

# Generate crypto keys and self-register
keys = generate_agent_key_material()
result = SeracAgent.register(
    agent_name="my-agent",
    ed25519_public_key=keys.signing.public_key_b64,
    x25519_public_key=keys.encryption.public_key_b64,
    encrypted_master_key=keys.encrypted_master_key,
    master_key_nonce=keys.master_key_nonce,
    key_commitment=keys.key_commitment,
)
agent = result["agent"]

# Store and retrieve data
agent.store("memory", "user:prefs", base64_data)
data = agent.retrieve("memory", "user:prefs")

JavaScript (serac-agent-sdk)

npm install serac-agent-sdk

import { SeracAgent, generateAgentKeyMaterial } from "serac-agent-sdk";

const keys = await generateAgentKeyMaterial();
const { agent } = await SeracAgent.register({
  agentName: "my-agent",
  ...keys,
});

await agent.store("memory", "user:prefs", base64Data);
