Keys everywhere
Provider keys copied into .env files, CI secrets and agent prompts, with nobody sure which ones are still live.
For teams & organizations
Help teams build on each other’s integrations.
Your platform team approves operations on internal, partner, and third-party APIs. Developers can use those operations in a typed SDK, deploy another team’s Unified App template with their own credentials, or give an agent selected tools through MCP.

The problem
Integration sprawl is a governance problem.
Every new app, team and agent adds another way into your critical services. Most companies can't say who can reach what.
The same client, built twice
Every team writes its own Stripe or Jira wrapper, then maintains it alone when the API changes.
Agents with broad tokens
An agent handed someone's personal token can do anything that person can, with no record of what it did.
Workspace governance
Share integration logic. Keep control of access.
Fulfillment owns the shipment lookup that powers the order page. Support can give its agent that same lookup through MCP. If the carrier changes its tracking API, Fulfillment updates one integration. The agent can still check a delivery, and changing its address remains a separate permission.
Separate team credentials
Deploy a shared integration with your team’s own bucket. Each team can manage its provider accounts independently.
Action-level permissions
Scope each team, app and agent to specific operations. Fused enforces this when the call runs, even if someone bypasses the SDK.
People, teams and SSO
Decide who can add services and build integrations. Company SSO is available on Enterprise.
A full activity trail
Every call is recorded: who made it, through which connection, and what the provider returned.
Changes reviewed like code
Integration config is planned, reviewed and applied. Versions are immutable, and API changes are flagged, never applied silently.
Verified webhooks, routed
Provider events are verified once in Fused, then delivered to the right app or agent.
Fused, across your company
Enable every team.
And everything they build.
A shared integration foundation for your teams. Approved capabilities for your agents. Service access for your applications. All governed through Fused.

Make integration knowledge a company asset.
Give every team a place to discover services, build capabilities, and connect to the services they need.
- 01Define once. Reuse across teams.
Import service contracts and share reviewed Unified Apps, SDKs, and MCP servers.
- 02Delegate access with boundaries.
Choose which services each team can use, with credential buckets and scoped permissions.
- 03Keep ownership visible.

Deployment
Run it where your data lives.
Fused has two parts. The Registry, hosted by Fused, knows how each service works. The Engine does the work: it holds credentials, enforces access and makes the calls. You choose where the Engine runs.
- Same license everywhere. Move from Fused Cloud to self-hosted without starting over.
- Isolated per workspace. Each workspace gets its own Engine, so your traffic and credentials are never pooled with anyone else's.
Fused Cloud
We provision an isolated Engine for your workspace. The fastest way to start, with nothing to operate.
Self-hosted
Run the Engine in your VPC or Kubernetes cluster. Credentials, payloads and tokens never leave your network.
Questions, answered
Built to be governed.
Your teams own the integration logic. Fused handles credentials, permissions and execution visibility.
It can, and most teams want it to. Deploy the Engine in your VPC, Kubernetes cluster or cloud of choice with a license key, or let Fused provision an isolated one for you. Either way, request payloads, encrypted credentials, connected-user tokens and webhook delivery state stay with the Engine.
Yes, that is the point. Platform teams decide which services and operations each team, application and agent can reach. A team can use a credential bucket without being able to read what is inside it.
Applications call Fused through a typed SDK or the REST API. Agents use the same approved access through MCP. Teams can also package a multi-step flow as a Unified App: reviewed TypeScript that both applications and agents call as one capability.
No. There is no canvas for sequencing business workflows. Fused gives your software a governed way to call APIs and receive webhooks, while your application keeps its own business logic.
Register a provider webhook, then choose which events each app receives. Fused verifies each event and routes it to a Unified App, an application's SDK receiver, or an agent's MCP event resource.
