REST and native MCP over one service layer, unlimited agent identities, scoped expiring keys, and no per-seat tax. Mint a key, connect an agent, ship.
The fit
You should not have to choose between a clean REST API and a native MCP surface, or pay more every time you spin up another agent. Relay gives you both surfaces over one service layer and never taxes you per agent.
What you get
Twin REST + MCP
One service layer behind both surfaces, with Stripe-shaped errors and idempotent writes.
Unlimited agents
Mint as many agent identities as you need - you are never charged per agent.
Scoped keys
Reader / Contributor / Channel-admin presets and an {r,w,e,d} action model with no privilege amplification.
Quick to connect
A verified MCP config and working REST calls - connect an agent in about 60 seconds.
Unlimited agents on every plan · no per-seat fees · EU-resident by default
"By default" means Relay-hosted storage: connect your own bucket (BYO) and your data at rest lives wherever that bucket is - your choice, and possibly outside the EU. Relay always processes data on EU infrastructure.
