What It Does

KHEPRA MCP connects your AI assistant directly to a hardened compliance engine. Ask Claude or any MCP client to scan a system, map findings to STIG/NIST/CMMC controls, and generate an executive-ready risk report — all without sending data to external APIs.

Key capabilities:

36,195 STIG/CCI/NIST 800-53/800-171/CMMC mappings (offline, bundled)
Post-quantum cryptographic attestation on every tool call (ML-DSA-65 / FIPS 204)
World's First DoD PQC STIG — 17 controls covering CNSA 2.0 / FIPS 203/204/205 + agentic AI / MCP (PQC-01-STIG-V1R1)
Godfather Report: dollar-denominated business impact per finding (FAIR model)
Air-gap and SCIF compatible — sovereign/ironbank modes make zero egress calls
Flat annual licensing — no per-token or per-query charges
Runs on your metal: on-prem, DoD, IC, classified environments

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:

Method	Best For	Startup
Hosted endpoint	Fastest start, cloud tools	Instant
Docker	Most users, easiest self-host	~2s
Compiled Binary	Air-gap, SCIF, performance	~300ms

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

Cloud Tool	Where to add MCP URL
Claude.ai (Pro/Team)	Settings → Integrations → MCP Servers
Cursor	`.cursor/mcp.json` → `url` field
OpenAI Assistants	API `tools` field with `type: "mcp"`
Glama.ai	Workspace → MCP Servers
Smithery.ai	Catalog → Self-hosted server

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 Registry (Community tier)

KHEPRA is listed on Smithery.ai and the MCP Registry. 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

Community Tier (Free — No License Key)

`pqc_stig` — World's First DoD PQC STIG ⭐

Assesses a source code directory against PQC-01-STIG-V1R1: 12 controls covering CNSA 2.0 algorithm approval, ML-DSA-65 key strength, ML-KEM-768 encapsulation, hybrid cryptography, key storage, constant-time implementation, and certificate chain requirements.

pqc_stig(scan_path?: string, profile?: "quick" | "full" | "executive")

Example: "Run pqc_stig on my project and tell me if I'm CNSA 2.0 compliant"

`nist_map`

Map CCI identifiers or STIG findings to NIST 800-53 Rev 5 controls.

`khepra_query_stig`

Query the 36,195-row STIG/CCI/NIST/CMMC compliance database by control ID.

`dark_crypto_contribute` (opt-in)

Contribute anonymized cryptographic algorithm telemetry to the SouHimBou AI Dark Crypto Intelligence Network. No PII. Opt-in only — never fires without explicit invocation.

Sovereign / Pharaoh Tier

`ert_scan`

Enterprise Risk & Threat scan across STIG, NIST 800-53, NIST 800-171, CMMC, and FedRAMP. Returns Godfather Report with dollar-denominated business impact.

ert_scan(target: string, frameworks?: string[], output_format?: "godfather" | "json" | "csv")

Example: "Run ert_scan on /etc and generate a Godfather Report"

`stig_check`

Automated RHEL-09-STIG-V1R3 compliance scan against a live system or configuration path.

`cmmc_assess`

Full CMMC Level 1, 2, or 3 assessment with gap analysis and POA&M generation.

Generate an executive Godfather Report from prior scan results: top 10 findings ranked by dollar exposure, remediation ROI, and FAIR model business impact.

+ 20 additional tools

agent_record, dag_attestation, flight_export, khepra_get_dag_chain, nhi_inventory, acp_status, owasp_agent_assess, khepra_export_attestation, khepra_export_poam, khepra_get_compliance_score, ert_crypto, ert_readiness, stig_benchmark, ir_analysis, vuln_hunter, sbom_generate, threat_model, khepra_query_threat_intel, discover_assets, and more.

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.

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.

Security Posture

Deploying advanced post-quantum cryptography, air-gapped isolation, and comprehensive STIG mappings — built in direct alignment with NSA & ASD Model Context Protocol guidelines.

NSA & ASD MCP Security Alignment

The NSA and Australian Signals Directorate (ASD) have published specific threat vectors for AI systems interacting with local environments. KHEPRA MCP is explicitly designed to mitigate every identified vector:

NSA/ASD Requirement	KHEPRA Implementation
Cryptographic validation of tool responses	ML-DSA-65 (Dilithium) signatures on all JSON-RPC 2.0 payloads
Input validation & sanitization	Parameter injection resistance via strict JSON Schema validation
Principle of least privilege credentials	Short-lived ephemeral tokens tied to specific task execution windows
Comprehensive audit logging	Tamper-evident events compiled into an immutable DAG structure
Resource consumption limits	Rate limiting + backpressure for LLM request loops
Authorization gates for sensitive actions	Human-in-the-loop gate for destructive state changes
Environment isolation	Containerized execution with zero-egress sovereign mode
Software supply chain integrity	Manifest pinning for all loaded tools and dependencies
Network exposure reduction	Air-gappable — zero internet transit in `sovereign`/`ironbank` modes
Post-quantum resilience	PQC-signed DAG trail protecting against harvest-now-decrypt-later
