Approve the operations
The platform team approves order lookup and shipment tracking. Changing a delivery address requires separate permission.
API integrations for teams and individuals
Connect your APIs once. Build on them everywhere.
Bring internal, partner, and third-party APIs into Fused. Reuse the same integrations across teams, side projects, and AI agents while staying in control of who can access what.

How teams use Fused
Build on the APIs your team has approved.
Customers want to know where their order is. The order page and the support agent need the same answer from two sources: your orders API and the shipping carrier.
Build the shipment lookup
Fulfillment builds a Unified App that takes an order number, finds its tracking number, and asks the carrier for the latest delivery status.
Use the lookup in two places
The web team calls the app through a typed SDK for the order page. Support gives its agent the same lookup through MCP to answer “Where’s my order?”
For individuals and solo developers
Connect your accounts once. Use them across projects.
Connect Jira and Slack to Fused, then choose what your assistant can do in each. It can look up open bugs and post a standup summary while your API keys stay in Fused.
- One link for your chosen tools. No separate connector to set up for each app.
- Your keys stay with Fused. The assistant never sees a password or token.
- Works with any MCP tool. Claude, Cursor and other MCP-compatible tools all use the same link.

Your workspace
Simple to start. Safe to keep using.
Every connection in one place
See what's connected and who is using it, and switch anything off from one dashboard.
No keys in prompts or config files
Fused stores your credentials and refreshes tokens. The assistant or app using them never sees them.
Only what you allow
Allow reading issues but not deleting projects. Permissions apply to each action, not just each service.
A record of every call
Know exactly what ran, when, and through which connection.
Who it's for
Built for one person. Ready for a whole company.
For individuals & solo devs
One place for your projects and AI assistants.
Keep business and side-project credentials separate. Give each assistant the services it needs and revoke its access when you choose.
- Connect accounts in a few clicks
- One link for any MCP-compatible AI tool
- SDKs, REST and webhooks when you want to build
Give your teams APIs they can build with.
Give developers a catalog of approved operations on internal and partner APIs. They can ship a feature using a typed SDK or build on an integration another team already maintains.
- Reuse a Unified App template with your team’s own credentials
- Expose selected operations to an agent through MCP
- Run on Fused Cloud or in your own infrastructure
Questions, answered
Fused, in plain terms.
How to connect APIs and decide who can use them.
Connect internal, partner, and third-party APIs in one Fused workspace. Reuse integrations across apps and AI agents, and control which actions each can take.
No. You can sign up, connect your accounts, and get a link for your AI tools entirely in the Fused dashboard. Developers get more on top: SDKs, a REST API, a CLI, and webhooks.
Fused gives you an MCP link. Add it to any assistant that supports MCP, such as Claude or Cursor, and it can find and use the actions you've allowed across your connected services. Your passwords and tokens are never shared with the assistant.
Fused stores your credentials encrypted and refreshes tokens automatically. You choose which actions each connection allows, you can revoke access at any time, and every call is recorded so you can see exactly what happened.
Fused can add any service whose API is described by an OpenAPI spec, including your company's own internal APIs.
Yes. Teams can run the Fused Engine in their own cloud or Kubernetes cluster, so credentials and traffic stay inside their network. See Fused for teams for the details.
