Setting up with Highlight
This MCP is not yet compatible with Highlight’s one-click setup. However, you can still use it with Highlight by following these steps:
- Download and install Highlight from highlightai.com/download
- Navigate to the plugins tab and select "Add Custom Plugin"
-
Configure the plugin with the settings below
Plugin Name
SeracCommand (node, npx, python, etc.)Please refer to the README for specific instructions on how to obtain API keys or other required environment variables.
- Enable "Start Automatically" if you want the plugin to start when Highlight launches
From the repository
Install the Python SDK (pip install serac-mcp) or JavaScript SDK (npm install serac-agent-sdk), generate agent key material, self-register, then use MCP tools (e.g., serac_store, serac_retrieve) over the streamable HTTP endpoint at https://serac.cloud/api/agent/mcp/v1.

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
