Thin on the hot path.
Engine is built to add control rather than waiting—the checks, credential resolution, and policy all happen on the way to a call you were going to make anyway.
Where integrations actually run
One runtime doing the work nobody wants to write twice.
For every call, Engine decides whether it is allowed, resolves the credential, applies the policy, makes the request, and records what happened. Applications and agents get one consistent way in. You get one place to change how any of it behaves.
Runs in your environment. Shared across products. Credentials never leave it.
Install the runtime
Download Fused Engine.
Choose a release for your host or pull the container image for Docker and Kubernetes. A Fused license key and Registry connection are required at runtime.
Inside the Engine
Five things you only have to get right once.
Access, credentials, governance, resilience, and visibility. Improve any of them in the Engine and every application and agent in the company gets the improvement.
01Contract-aware executionEngine runs approved operations, not arbitrary URLs, so undeclared inputs get rejected before they reach a provider.
02Credentials + OAuthSecrets and connected accounts are resolved when an approved operation runs, and never handed back to the caller.
03Governance by teamService access and shared rate limits are enforced once, instead of re-implemented in every product.
04Reliable executionRetries, pagination, concurrency, and provider rate-limit handling live in the runtime shared across interfaces.
05Logs + service analyticsOne activity trail shows how integrations perform and which services teams actually use.
Governance that scales past one team.
Decide who can use each service, how credentials and OAuth connections get resolved, and where shared limits apply. Once, centrally, for everyone.
Integrations you can actually operate.
Central retries, logs, and usage analytics make service health and adoption visible without instrumenting each product separately.
A closer look
One operation, wired into whatever's asking for it.
Unified Operations get the same treatment as everything else in Engine: define the coordination once, and let the caller—an application's SDK or an agent's MCP server—reach it through the same clean front door.
Written once, called from either side
Inputs, order, data mapping, and rollback get defined a single time. A typed SDK method and an agent's execute call are reaching the exact same definition, not two versions quietly drifting apart.
The whole plan gets checked, not just each step
Engine validates the complete sequence—every binding and every target—before the first provider request goes out. Nothing gets added silently, and nothing gets skipped by accident.
Still authorised one call at a time
A Unified Operation is not a backdoor around access control. Every underlying action is checked against the caller's token, credentials, and provider policy, exactly as if it ran alone.
Room for a real process
Up to 64 operations and 16 bindings in one definition—enough for an actual business workflow, not just a two-step party trick.
Put the integration work somewhere sensible.
Run Engine in the environment you choose, and give every application and agent in the company the same way in.
