Any API. Every AI agent. One gateway.
Relay turns any REST API into real MCP tools — automatically. One sentence becomes a working checkout, and every sale updates your inventory, your books, your team — without you lifting a finger.

Done — checkout page, QR code, and dashboard are live.
What it’s actually built on
6
Paystack endpoints wired end-to-end
Three parts, one gateway
Infra a developer can test. A product a founder can use.
Paste an API. Get real MCP tools.
Relay parses an OpenAPI spec or a raw curl command and generates a working MCP server — typed schemas, real handlers, downloadable mcp.json. Point any MCP-compatible agent at it directly.
Watch an agent actually use them.
Type a request in plain English. See the exact trace: reasoning, the tool it picked, the call it made, and the real response from the live API behind it — not a simulation.
One sentence, one working product.
“Create a payment page for hackathon tickets, ₦5,000, cap 100” becomes a live checkout link, a QR code, and a dashboard. Paystack moves the money — Wire connects the sale to whatever else runs your business.

The actual sequence
How it works, in order
- 01
Paste your API
A spec, a curl command, or the pre-loaded Paystack preset — no setup required to try it.
- 02
Get MCP tools
A real MCP server generates in seconds — one typed tool per endpoint, auth handled.
- 03
Watch an agent use them
A live trace of reasoning, tool calls, and real responses — side by side, nothing hidden.
- 04
Ship the result
A checkout page, a QR code, a live dashboard — built from the same tools, and wired to update whatever else runs your business.
Under the hood
What’s actually running, not what we claim
6
Paystack operations wired end-to-end — not a demo stub
2
consumer surfaces on one gateway: a dev playground and a live product
1
shared tool definition — the MCP server, the playground, and Flow all call the same handlers, so nothing drifts
Built in one hackathon sprint.
Try it live.
The Paystack preset works with zero setup — paste your own API if you want to see it generalize.
