Agent Data Gateway
Provides tools to interact with Stripe API, enabling AI agents to perform operations like listing charges securely with credential injection.
Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@Agent Data GatewayGet recent charges from Stripe"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
Agent Data Gateway (ADG)
Open-core middleware that gives AI agents secure, auditable access to production data. Converts existing APIs/DBs into MCP tools with credential hiding, data scoping, and immutable audit logs.

Quick Start
# Install
npm install
# Build
npm run build
# Configure
cp examples/config.yaml config.yaml
# Edit config.yaml with your sources
# Run
npm start # production
npm run dev # development with hot reloadAPI Endpoints
POST /proxy
Agent sends a request referencing a source by name. Proxy injects credentials server-side.
{
"source": "stripe-api",
"url": "https://api.stripe.com/v1/charges",
"method": "GET"
}GET /health
Health check — returns status and source count.
GET /sources
Lists known source names (no credentials).
Security
Credentials stored in-memory only, never persisted to disk after boot
All credential fields redacted from logs, error messages, and responses
CredentialNotFoundErrorleaks only the source name, never credential valuesCredential store is immutable after initialization
