Overview

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);

Architecture

  • Backend: Fastify + PostgreSQL + Redis
  • Storage: OVH S3 (eu-west-par, France)
  • Encryption: X25519 ECDH + AES-256-GCM (agents) / Argon2id + XChaCha20-Poly1305 (humans)
  • Auth: Ed25519 challenge-response + API key exchange → JWT (HMAC-SHA256)
  • Hosting: OVH Roubaix, France

Bring your real authenticated browser session to AI coding agents. Local-first MCP server + Chrome MV3 extension. No cloud. No telemetry.
@Cubenest

peek records the user's actual logged-in browser (DOM via rrweb, console events, network metadata, optional response bodies via opt-in Deep capture) through a Chrome MV3 extension. The extension ships events through a native-messaging stdio bridge to a local MCP server (peek-mcp), which persists them to a SQLite database at ~/.peek/sessions.db. AI coding agents (Claude Code, Cursor, Cline, Windsurf) read sessions from the database via 10 MCP tools: Tool What it does list_recent_sessions List recently recorded sessions (id, origin, ts, event count). get_session_summary LLM-readable narrative summary of a session. get_session_console_errors Console errors recorded in a session. get_session_network_errors Failed/notable network requests in a session. get_user_action_before_error Last N user actions before a console error. generate_playwright_repro Generate a runnable Playwright test from a session. get_dom_snapshot Reconstruct the DOM at a given timestamp. query_dom_history Timeline of attribute/text changes for a selector. request_authorization Side-panel consent for write actions (Level 3). execute_action Dispatch a UI action (gated by permission level + destructive blocklist). Why local-first matters Every other "browser session for AI" tool ships to a vendor cloud. peek's SQLite + extension live on the user's machine — no remote endpoints, no telemetry. The privacy policy (docs/peek/PRIVACY_POLICY.md) is the source of truth. Install # 1. Add the MCP server to Claude Code claude mcp add peek -- npx -y @peekdev/mcp # 2. Install the Chrome extension from the Chrome Web Store # (link added once the CWS listing is approved)
