Self-hosting

Requires a Cloudflare account (Workers + D1 + KV).

1. Clone and install

git clone https://github.com/kajaril/sovereignty-scan-mcp
cd sovereignty-scan-mcp
npm install

2. Create infrastructure

npx wrangler d1 create sovereignty-db-free
npx wrangler kv:namespace create CACHE_KV
npx wrangler rate-limit:namespace create RATE_LIMITER
npx wrangler rate-limit:namespace create BURST_LIMITER

Copy the IDs printed by each command into wrangler.jsonc under d1_databases, kv_namespaces, and unsafe.bindings.

3. Apply schema and seed data

npx wrangler d1 execute sovereignty-db-free --remote --file=migrations/0001_providers.sql
node --input-type=module -e "
  import { generateSeedSQL } from './src/seed.js';
  process.stdout.write(generateSeedSQL());
" | npx wrangler d1 execute sovereignty-db-free --remote --command=-

4. Deploy

npx wrangler deploy

The custom domain (sovereignty-scan.kajaril.com) in the default config is owned by kajaril — remove or replace the routes entry with your own domain or use the default *.workers.dev URL.

Health

GET https://sovereignty-scan.kajaril.com/health

Returns a structured payload (HTTP 200):

{
  "status": "ok",
  "provider_count": 55,
  "anthropic_path_count": 3,
  "last_kv_refresh": "2026-05-11T00:00:00.000Z",
  "cache_age_seconds": 86400,
  "schema_version": "0001"
}

status is "ok" when D1 is reachable, "degraded" otherwise. cache_age_seconds is null if the KV cache has never been warmed.
