Build on what is running.

Connect your own systems to an Ardyn runtime through four generic methods, verify every receipt offline, and connect agents to ACTA MCP. Commands on these pages were run as written on a clean machine.

Quickstart: first receipt ACTA MCP

Connect your own system

Four integration guides.

Ardyn → MCP server

MCP

Guide → OpenAPI 3.0 / 3.1

HTTP API

Import a description, read and update a record with version checks, reconcile a lost response.

Guide → Observe only

Events & telemetry

Signed webhooks and OpenTelemetry traces, duplicates and gaps, no write access needed.

Guide → ardyn-pack/2

Packs

Write, sign and install an integration against the published format; upgrade, roll back, remove.

Guide →

Already run a workflow engine, tool broker or API gateway? Connect it through one of these methods. What it reports about systems behind it is recorded as reported by that intermediary — not as independently confirmed by each downstream system.
