How to deploy

A drop-in governing proxy you run yourself — your infrastructure, your Gemini key, your policy. It is open source; nothing routes through a third party. No full platform required.

1 · Deploy it (one click — you are prompted for your key):

Deploy to Render  Docker / other

Or run it directly:

git clone https://github.com/ai-ankqush/aca-mcp-gateway
cd aca-mcp-gateway
GEMINI_API_KEY=your-key GATEWAY_TOKEN=choose-a-secret node server.mjs   # :8080

2 · Point your apps at it — base URL = your gateway, key = your gateway token (the gateway holds the GEMINI_API_KEY):

POST GATEWAY_URL + "/v1beta/models/{model}:generateContent"
# requests go to  GATEWAY_URL/v1beta/models/{model}:generateContent

What it is

Deploy Gemini under control — the same ACA gateway with the Google Gemini adapter. Bring your own Gemini key; route your apps through the governing proxy and every request and function call is governed and logged. A Policy Enforcement Point applies ACA's SEE / DECIDE / DO to every action (scope, sensitive-data boundary, human approval, action-class limits, kill switch), writes a tamper-evident evidence log, and ships a passing assurance suite (prompt-injection, data-access-boundary, tool/action-limit, approval-bypass, evidence-reconstruction). Vendor-neutral: one repo, swappable model adapters. Stateless per request, so it scales to tens of thousands of employees behind a load balancer. Zero dependencies, Apache-2.0.
