Requests flow in with one org key (sky rails); the gateway routes to providers and streams telemetry out (orange rails).

Why it matters

Built for production agents—not prompt playgrounds

How this harness capability fits the Exemplar platform: one identity, one policy layer, and one audit trail across console, MCP, and SDK.

Why Exemplar

Fragmented integrations mean every agent team rebuilds bridges to AWS, Linear, Snyk, and internal APIs—with different auth and no shared audit.

Exemplar’s gateway is the standardized bridge: 50+ connectors become MCP tools automatically, whether the caller is a human in the console or an agent in any framework.

What Exemplar delivers

Out-of-the-box MCP and API integrations anchored to catalog and Day 2 Ops—tools generated from connectors, not hand-wired per client.

Framework-agnostic agent entry: LangGraph, CrewAI, AutoGen, ADK, and custom runtimes share the same governed gateway.

LLM routing with policy hooks—model choice, fallbacks, and spend caps at the gateway—not buried in client config.

How teams use it

Enable connectors; MCP tools appear for IDE clients and agent frameworks without per-integration glue code.

Register custom agents and sub-agents; orchestration routes tool calls through the gateway with structured allow/deny responses.

Capability checklist

Route LLM traffic through governed endpoints
Auto-expose connector capabilities as MCP tools (Cursor, Claude, custom agents)
Out-of-box agents that work with any agent framework
Same tool surface for console operators and autonomous agents
Scoped credentials—secrets never enter model context
