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);
