AgentAegis MCP Server

Every cybersecurity service, callable by any AI agent, billed per use.

AgentAegis is an MCP server that lets AI agents perform cybersecurity operations on demand — from compliance checks to vulnerability scans to code security analysis. It wraps best-in-class open-source scanning engines (nmap, Nuclei, sslyze, Semgrep, trufflehog, trivy) in clean, agent-discoverable tool definitions with structured inputs and outputs.

Phase 2 ships: HTTP transport for remote deployment, x402 micropayments, API key auth with monthly limits, Supabase persistence, webhooks, ISO 27001 + HIPAA frameworks, Railway deploy config, and a full test suite.

Quick Start

Local (stdio for Claude Desktop)

git clone https://github.com/astafford8488/agentaegis-mcp.git
cd agentaegis-mcp
pnpm install
cp .env.example .env  # add API keys
pnpm build

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "agentaegis": {
      "command": "node",
      "args": ["/path/to/agentaegis-mcp/dist/index.js"],
      "env": {
        "NVD_API_KEY": "...",
        "ABUSEIPDB_API_KEY": "...",
        "OTX_API_KEY": "...",
        "ABUSECH_API_KEY": "...",
        "HIBP_API_KEY": "..."
      }
    }
  }
}

Remote (HTTP, for agent platforms)

# Local dev
pnpm dev:http

# Production via Docker
docker compose -f docker/docker-compose.yml up -d

# Production via Railway
railway up

Connect from any MCP-aware agent:

POST https://your-host/mcp
Authorization: Bearer aegis_<your-api-key>

HTTP API (Phase 2)

Endpoint	Method	Auth	Description
/health	GET	None	Health check
/pricing	GET	None	Tool catalog with prices
/v1/customers	POST	None	Create customer account
/v1/customers/:id/api-keys	POST	None	Issue an API key
/v1/customers/:id/usage	GET	API key	Usage statistics
/v1/jobs/:jobId	GET	API key	Async scan job status
/mcp	POST	API key OR x402	MCP Streamable HTTP transport

Payment Flow

Option 1: API Key — Customer registers, gets a key, pays via prepaid balance or invoice. Each tool call deducts from the monthly budget.

curl -X POST https://api.agentaegis.org/v1/customers \
  -H "Content-Type: application/json" \
  -d '{"email":"you@company.com","name":"Your Name"}'

curl -X POST https://api.agentaegis.org/v1/customers/<id>/api-keys \
  -H "Content-Type: application/json" \
  -d '{"name":"production","monthly_limit_usd":100}'

Option 2: x402 Micropayment — No signup. Each tool call settles on-chain via USDC. The server returns 402 Payment Required with payment requirements; the client signs and retries with X-PAYMENT header.

Deployment

Railway (Recommended)

railway login
railway init
railway up

Required env vars (set in Railway dashboard):

• SUPABASE_URL, SUPABASE_SERVICE_KEY
• X402_PAYEE_ADDRESS (your wallet)
• NVD_API_KEY, ABUSEIPDB_API_KEY, OTX_API_KEY, ABUSECH_API_KEY, HIBP_API_KEY

Database setup

Run the migration in your Supabase SQL editor:

cat supabase/migrations/001_initial_schema.sql

Security Policy

• Target validation: Only public IPs and registered domains. Private/reserved ranges blocked.
• Scan isolation: Each scan runs in an isolated process with temp directory cleanup.
• Code safety: Repos cloned shallow (depth=1), max 500MB, 5-minute timeout, no execution.
• Secret redaction: Full secret values never returned — first 4 and last 4 characters only.
• Rate limiting: Per API key AND per target. Max 5 concurrent scans, 10/hour per target.
• Audit logging: All tool calls logged to usage_log (90-day retention).
• API key hashing: Keys stored as SHA-256 hashes; raw keys never stored.

Responsible Use

AgentAegis scanning tools must only be used against systems you own or have explicit written authorization to test. By using this service, you agree that:

1. You have authorization from the system owner to perform security testing
2. You will not use these tools for unauthorized access or malicious purposes
3. You accept responsibility for any scans initiated through your API key
