From APIs to AI fast and easy

Transform Your API-First Architecture

Your APIs are ready. Are your workflows ready to evolve? 🚀

OpenAPI Endpoints

API-First Done Right

APIs as Building Blocks

APIs are your building blocks. Reliable, deterministic, and ready for the next step: AI orchestration.

Expose APIs as MCP Tools

Step 1 – APIs Become Discoverable Tools

Each API endpoint is now an MCP tool, ready to be consumed by AI agents or orchestrators.

Orchestrator agnostic (n8n, LangFlow, Flowise, Temporal, you name it)

Compose Workflows

Step 2 – Compose Workflows as MCP Tools

Workflows can combine multiple tools into reusable, deterministic units, just like building microservices but for AI.

Recursive Composition

Workflows can call MCPs from different contexts, creating a hierarchy of reusable components.

Infinite AI Pipelines

Step 3 – Workflows as MCP Servers

Expose workflows as MCP tools. Now your orchestrator can call workflows of workflows, creating infinite deterministic AI pipelines.

API-First to AI-First

Don't Reinvent the Wheel

Evolve your API-first architecture into AI-powered workflows without starting from scratch.

HAPI Stack Makes It Easy

  • No pain integration: use existing OAS/Swagger files
  • Rapid adoption: discover and call APIs instantly
  • Deterministic workflows: enterprise-ready
  • Recursive composition: workflows re-used as MCP tools
  • Standards-based: OpenAPI, JSON-Schema, JSON-RPC, MCP, Arazzo

Ready to Transform?

  • Your APIs are ready. Your workflows are ready.
