Go from OpenAPI to production MCP in minutes—OAuth, identity, runtime, and observability included. The secure layer between your API and the agents that depend on it.

No MCP runtime to ship — just your OpenAPI.
No service accounts — OAuth 2.1, real users.
No agent code in your API — keep it pure REST.
“Our AI-powered UI ships with real user identity, real audit trails, and zero glue code. Emcy did the boring parts so we could ship the magic.”

Global edge MCP
One CLI deploy. Endpoints live near every agent.
Multi-region runtime with regional health, gateway routing, and tool-call telemetry — out of the box.
Per-user identity, baked in
Every tool call carries the signed-in user.
No shared service accounts. No identity bypass. The agent hits your API with the signed-in user's own token — right scopes, real audit trail, nothing new to wire in your backend.
“Our ask was simple: let agents call our API as the actual signed-in user — same scopes, same audit trail, no service accounts. MCP Stack made it simple and integrated into our existing application and OAuth infrastructure.”
@emcy/agent-sdk
One component. The user's identity comes with it.
Forget WebSockets, streaming, retries, and refreshing tokens mid-tool-call. Pass your signed-in user, render <EmcyChat />. The OAuth flow above runs underneath — automatically.
import { EmcyChat } from "@emcy/agent-sdk/react-embed";
<EmcyChat
agentId="ag_invoices"
apiKey={process.env.EMCY_KEY}
userIdentity={{
subject: user.id,
email: user.email,
}}
/>
“Drop-in chat that knows who the user is. That was the whole ask.”
Simple, usage-based
Deploy MCP Servers with OAuth in minutes.
Every plan includes a globally deployed MCP server — MCP Stack runs the runtime in regions close to your agents, with a stable public MCP URL, OAuth, and request logs included.
