04Model Context Protocol

Every group is also a tool server for AI agents.

The portal turns each API group into an MCP server straight from its OpenAPI specs. Calls run with your app's keys, so quotas and logs still apply. Anything that moves money stays switched off until an operator allows it.

01
Scenario sandbox
Every endpoint ships with named outcomes. Send amount 1 and watch an insufficient-funds callback arrive.
02
Callback inspector
See each callback we sent, what your server answered, and replay it with one click.
03
Request log
Every sandbox and production call, with the request, the response and the reason it failed.
04
Teams and SSO
Invite colleagues with roles. Sign in with Google, GitHub or your company's identity provider.
05
Key rotation
Issue a second secret, deploy, then retire the first. No downtime and no support ticket.
06
Tools for AI agents
Each API group is also an MCP server, so assistants can call the same APIs with your keys.

Make the first call before your coffee cools.
