Connect your accounts
Pick a service and sign in. Fused keeps the connection working, including refreshing tokens when they expire.
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 it works
Three steps. No glue code.
Everything below happens in the Fused dashboard. Developers can do the same from the CLI or code.
Choose what's allowed
Decide which actions each connection can perform. Anything you leave out is refused, whoever asks.
Use it anywhere
Paste your Fused link into your AI assistant, call it from your code, or hand it to your team's agents.
Works with your AI tools
Give your AI assistant real reach.
Add Fused to your AI assistant once and it can work across everything you've connected: read your issues, look up a customer in Stripe, post to Slack. It only does what you've allowed.
- One link, every service. 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.
Approve services once so developers can generate SDKs, reuse another team’s integration logic, and give agents scoped tools through MCP.
- Shared credentials teams can use but not read
- Access per team, app and agent, down to single actions
- 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.
