Sample Code & Playgrounds

Explore live test harnesses, code snippets, and delegation simulation tools for MCP-I

Sample Code & Playgrounds

Delegation Flow (End-to-End)

const userDid = await kyaOsClient.ensureUserHasDid("user-123");
const agentDid = "did:web:knowthat.ai:agent:concert-ticket-buyer";

const credential = await kyaOsClient.credentials.issueDelegation({
  issuerDid: userDid,
  subjectDid: agentDid,
  scope: ["read:email"],
  expiration: "2025-12-31T23:59:59Z"
});

const isValid = await kyaOsClient.verify.delegation({
  credential,
  subjectDid: agentDid
});

if (!isValid) {
  await kyaOsClient.credentials.revoke(credential.id, {
    reason: "revoked for testing"
  });
}

Playground Flows (OAuth + Delegation)

const result = await kyaOsClient.sdk.oauthFlowTest({
  redirectUri: "https://example.com/callback",
  requestedScope: ["submit:claim"],
  clientDid: "did:web:client.example"
});

Test Harness Utilities

await kyaOsClient.sdk.runTests();               // Run entire MCP-I test suite
await kyaOsClient.sdk.proxyFlowTest();          // Simulate proxy credential flow
await kyaOsClient.sdk.simulateAuthorization();  // Run delegated access scenario

Store and retrieve results:

await kyaOsClient.sdk.storeTestResult({
  testId: "chain-depth-3",
  status: "passed"
});

const results = await kyaOsClient.sdk.getStoredTestResults();

Chain Resolution Tools

Verify indexed credential chains:

const chain = await kyaOsClient.registry.delegation.resolveChain({
  subjectDid: agentDid
});

chain.forEach(link => {
  console.log("Issuer:", link.issuer, "→ Subject:", link.subject);
});

Future Playgrounds

The following tools are under development:

  • Credential Builder UI
  • Delegation Chain Visualizer
  • Policy Rule Tester (Trust Score sandbox)
