Use Environment Variables as Credentials

import { agent, subAgent, mcpTool, credential } from "@inkeep/agents-sdk";
import { CredentialStoreType } from "@inkeep/agents-core";

// Step 1: Reference the credential created in the environment file
const stripeCredential = credential({
  id: 'stripe-credential',
  name: 'Stripe Credential',
  type: CredentialStoreType.memory,
  credentialStoreId: 'memory-default',
  retrievalParams: {
    "key": "<environment-variable-name>", // where <environment-variable-name> is the name of the environment variable that contains the credential value, for example, STRIPE_API_KEY
  },
});

// Step 2: Use credential in MCP tool
const stripeTool = mcpTool({
  id: 'stripe-tool',
  name: 'Stripe Tool',
  description: 'Access Stripe payment services',
  serverUrl: 'https://mcp.stripe.com/mcp',
  credential: stripeCredential,
});
