What Badge MCP Server does

Persistent identity for AI agents across merchant sites. Badge gives agents a credential they carry on every request — merchants verify it, trust accumulates across visits, and agents that build history earn better treatment over time.

README

Badge by kya labs

Framework-agnostic. Transport-agnostic. Zero runtime dependencies.

Badge SDK

The SDK is the primary integration surface. Three methods cover the full lifecycle:

import { Badge } from "@kyalabs/badge-sdk";

const badge = await Badge.init();
const runId = badge.startRun();

await badge.declareVisit({
  merchant: "store.example.com",
  runId,
  url: "https://store.example.com/cart",
});

await badge.reportOutcome({
  merchant: "store.example.com",
  runId,
  outcome: "not_denied",
});

No signup. No API key. Badge.init() issues a guest pass on first run and caches it to disk. Identity survives process restarts.

npm install @kyalabs/badge-sdk

Full SDK documentation →

What the SDK covers

Identity model — three-tier ladder: guest pass (gp_v1_*) → badge token (kya_*) → authenticated identity
Lifecycle tracking — declare visits, report outcomes, correlate with run IDs
Offline resilience — never throws on network failure, deterministic fallback on every call
UCP integration — io.kyalabs.common.identity Credential Provider, published schemas, ES256-signed JWTs
Scoring — outcomes feed kyaScore (500–850), portable across merchants

Badge MCP Server

For MCP client users (Claude Desktop, Cursor, Windsurf), Badge also ships as an MCP tool server. The MCP server wraps the SDK — same identity model, same tokens, same scoring.

npx @kyalabs/badge

The SDK is the canonical integration path for platform builders and agent frameworks. The MCP server is a convenience wrapper for end users working within MCP clients.
