Architecture: Free Community Kernel vs. KTOS Commercial Platform

To ensure clean commercial boundaries for partners, defense contractors, and developers, the KHEPRA ecosystem operates across two distinct layers:

---

Tiers & Gating (The 4-Tier Commercial & Sovereign Model)

---

What It Does (Free Community Kernel)

PQC-Khepra-MCP connects your AI assistant (Claude Code, Cursor, Antigravity, Cline) directly to a post-quantum cryptographic security layer:

• ML-DSA-65 Signing: FIPS 204 post-quantum signing on every tool call and DAG attestation. Key encapsulation is pre-standard CRYSTALS-Kyber-1024; FIPS 203 ML-KEM-1024 migration is in progress.
• Autonomous Flight Recording: Automatically logs all agent tool invocations, inputs, and outcomes to tamper-evident NDJSON hash chains.
• Local Host & Asset Discovery: Enumerate system runtimes, network interfaces, and environment properties locally.
• Air-Gap & Sovereign Operation: Runs 100% offline with zero cloud telemetry or egress calls.
• KSCL-1.0 License: free community and evaluation use. Commercial production use, enterprise deployment and managed-service hosting require a commercial agreement; see LICENSE.

Quickstart — Hosted Endpoint (Zero Install)

The fastest path to a live compliance tool in your AI client. No Docker, no binary, no build:

{
  "mcpServers": {
    "khepra": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://mcp.souhimbou.ai/sse"]
    }
  }
}

Or if your client supports native SSE transport:

https://mcp.souhimbou.ai/sse

Health check: https://mcp.souhimbou.ai/mcp/v1/health

Data note: The hosted endpoint runs in edge mode — DAG is in-memory and ephemeral. For persistent, signed audit trails and air-gap deployment, use the self-hosted options below.

---

Self-Hosted Installation

For sovereign/air-gap deployment: Docker (recommended, no build required) or compiled binary (fastest startup, SCIF-ready). Both support the same environment variables and all MCP clients.

Choose your path:

---

Option A: Docker (Recommended)

Requires Docker Desktop or Docker Engine. The image is pre-built and ships the full compliance database — no additional downloads in sovereign mode.

# Pull once
docker pull ghcr.io/nouchix/pqc-khepra-mcp:latest

# Test it (should print the initialize response and exit)
echo '{"jsonrpc":"2.0","method":"initialize","params":{"protocolVersion":"2025-11-25","capabilities":{},"clientInfo":{"name":"test","version":"1.0"}},"id":0}' \
  | docker run --rm -i -e KHEPRA_MODE=sovereign ghcr.io/nouchix/pqc-khepra-mcp:latest

---

Option B: Compiled Binary

Requires Go 1.21+ for building, or download a pre-built release from GitHub Releases.

git clone https://github.com/nouchix/PQC-Khepra-MCP.git
cd PQC-Khepra-MCP

# Build (cross-compile for your OS)
go build -o khepra-mcp ./cmd/khepra-mcp        # Linux / macOS
go build -o khepra-mcp.exe ./cmd/khepra-mcp    # Windows

# Test the binary
echo '{"jsonrpc":"2.0","method":"initialize","params":{"protocolVersion":"2025-11-25","capabilities":{},"clientInfo":{"name":"test","version":"1.0"}},"id":0}' \
  | KHEPRA_MODE=sovereign ./khepra-mcp

Windows — using the batch launcher

The repo ships a run-mcp.bat launcher for Windows. It uses the pre-built binary (fast path) and falls back to go run automatically:

:: run-mcp.bat is already in the repo at the root of PQC-Khepra-MCP
:: Point your MCP client to: cmd /c C:\path\to\PQC-Khepra-MCP\run-mcp.bat

  }
}

---

Cloud / SaaS AI Tools (Claude.ai, ChatGPT, Gemini, etc.)

Use the live hosted endpoint at mcp.souhimbou.ai — no setup required:

Option 1 — Live hosted endpoint (recommended, zero setup)

{
  "mcpServers": {
    "khepra": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://mcp.souhimbou.ai/sse"]
    }
  }
}

Or direct SSE URL for tools that accept it:

https://mcp.souhimbou.ai/sse

Option 2 — mcp-remote proxy (local binary behind the bridge)

If you need sovereign mode (zero egress) proxied to a cloud tool:

# Install once
npm install -g mcp-remote

# Bridge your local sovereign instance
KHEPRA_MODE=sovereign mcp-remote \
  --server "docker run --rm -i -e KHEPRA_MODE=sovereign ghcr.io/nouchix/pqc-khepra-mcp:latest" \
  --port 3000

# Point cloud tool to:
# http://localhost:3000/sse

Security note: In sovereign/ironbank mode, KHEPRA makes zero egress calls — only the bridge connection to the cloud tool carries data.

Option 3 — Smithery / MCP Registries (Community tier)

KHEPRA is listed across all major MCP discovery platforms. Cloud tools that support registry-based discovery can install it directly:

Registry ID: io.github.nouchix/pqc-khepra-mcp

---

Validation — Test Your Installation

Run this from your terminal to verify the server responds correctly:

# Docker
echo '{"jsonrpc":"2.0","method":"tools/list","params":{},"id":1}' \
  | docker run --rm -i -e KHEPRA_MODE=sovereign ghcr.io/nouchix/pqc-khepra-mcp:latest

# Binary (Linux / macOS)
echo '{"jsonrpc":"2.0","method":"tools/list","params":{},"id":1}' \
  | KHEPRA_MODE=sovereign ./khepra-mcp

# Binary (Windows PowerShell)
'{"jsonrpc":"2.0","method":"tools/list","params":{},"id":1}' \
  | & ".\khepra-mcp.exe"

Expected output: a JSON-RPC response listing all available tools. If you see "tools": [...] with 12+ entries — you're connected.

Full protocol validation (Windows)

# Runs the complete Claude Desktop handshake sequence and validates all responses
.\scripts\test-mcp-handshake.ps1 -BinaryPath ".\khepra-mcp.exe"

# Expected output:
# [PASS] initialize | protocolVersion=2025-11-25 | listChanged=False
# [PASS] tools/list | count=34
# TRL-10 READY - Server passes full Claude Desktop protocol validation

---

The Godfather Report

Unlike compliance scanners that output a wall of CVEs, KHEPRA translates findings into the language executives care about:

Finding: RHEL-09-212030 — No FIPS-validated crypto on /etc/ssh
Severity: CAT I (HIGH)
Business Impact: $2.4M estimated breach exposure (FAIR model)
Remediation Cost: $800 (4 hours engineer time)
ROI: 3,000x

Every finding includes control ID, framework mapping, business impact in dollars, remediation cost estimate, and ROI.

---

Deployment Modes

Set via KHEPRA_MODE environment variable. Unknown values are rejected at startup and fall back to sovereign (fail-closed).

---

Environment Variables

---

Air-Gap & SCIF Deployment

KHEPRA makes zero external network calls in sovereign and ironbank modes:

• License validated offline via ML-DSA-65 signed license.adinkhepra file
• Compliance databases (36,195 mappings) bundled in container — no external downloads
• No telemetry, no heartbeat, no egress — verified at the transport layer

# Transfer image to air-gapped network
docker save ghcr.io/nouchix/pqc-khepra-mcp:latest | gzip > khepra-mcp.tar.gz

# On air-gapped host:
docker load < khepra-mcp.tar.gz

Note on telemetry: The dark_crypto_contribute tool (Community tier) sends anonymized cryptographic algorithm telemetry to the SouHimBou AI intelligence network only when explicitly invoked by the user. It is never triggered automatically. In sovereign/ironbank mode, all network calls are blocked at the transport layer regardless.
