# Fused - [Fused: one controlled path to every service](https://docs.usefused.com/introduction.md): One controlled path from your applications and agents to every service they depend on. - [Get an Engine running](https://docs.usefused.com/deploy-an-engine.md): Stand up the runtime everything else in Fused talks to. - [Quickstart](https://docs.usefused.com/quickstart.md): Install the CLI, enable a service, and ship a working SDK. - [Enable a service](https://docs.usefused.com/workspace/enable-a-service.md): Make a service available to every SDK and MCP server in your workspace. - [Bring your own API in](https://docs.usefused.com/workspace/bring-your-own-api.md): Turn a spec, a GraphQL endpoint, or a documentation page into a versioned service. - [Manage versions and deprecation](https://docs.usefused.com/workspace/manage-versions.md): Run several versions of a service at once, and retire one without breaking what already shipped. - [Handle provider limits and failures](https://docs.usefused.com/workspace/handle-provider-limits.md): Rate limits, retries, and pagination handled once in the runtime instead of in every feature. - [Share access with teams](https://docs.usefused.com/workspace/share-access.md): Give a team exactly the services, buckets, and apps it needs — and nothing else. - [Build an SDK](https://docs.usefused.com/app/build-an-sdk.md): Turn a set of approved operations into a typed package your product can import. - [Use it in your app](https://docs.usefused.com/app/use-in-your-app.md): Install the generated package and stand up a client your application can hold. - [Run an operation](https://docs.usefused.com/app/run-an-operation.md): Call an approved operation from your application and handle what comes back. - [Test from the CLI](https://docs.usefused.com/app/testing/from-the-cli.md): Prove credentials, scope, and routing from a terminal or a CI job — without writing application code. - [Call over REST](https://docs.usefused.com/app/testing/over-rest.md): One HTTP endpoint, for languages with no generated package. - [Ship a new version](https://docs.usefused.com/app/ship-a-new-version.md): Change what an SDK exposes without rewriting the contract of software already in production. - [Receive provider events](https://docs.usefused.com/app/receive-events.md): Register inbound webhooks and route their events to the SDK that asked for them. - [Issue execution tokens](https://docs.usefused.com/app/issue-tokens.md): Give a running application a credential that calls your SDK — and nothing else. - [Declare a unified operation](https://docs.usefused.com/app/unified/declare.md): Turn several provider calls into one SDK or MCP operation, with dependencies and rollback. - [Call a unified operation](https://docs.usefused.com/app/unified/call.md): Choose targets, route each service, and read what comes back. - [Deploy an MCP server](https://docs.usefused.com/mcp/deploy-a-server.md): Stand up one Engine-hosted MCP server that reaches every service an agent is allowed to use. - [Use the MCP server](https://docs.usefused.com/mcp/use-the-server.md): Connect a client, open a session, and let an agent work across every approved service. - [Create a token for an agent](https://docs.usefused.com/mcp/agent-tokens.md): Narrow an MCP token to exact operations and a short lifetime before an agent uses it. - [Tokens for OAuth services](https://docs.usefused.com/mcp/oauth-tokens.md): Give an agent access to a provider that acts on behalf of individual users. - [Store credentials](https://docs.usefused.com/bucket/store-credentials.md): Put a provider credential somewhere your apps can use it without ever seeing it. - [Connect a user's account](https://docs.usefused.com/bucket/connect-user-accounts.md): Run OAuth once, per end user, and let the Engine keep the tokens working. - [Share a bucket](https://docs.usefused.com/bucket/share-a-bucket.md): Let another team build on your credentials without being able to read them. - [Know when something changes](https://docs.usefused.com/notifications.md): Provider drift, version changes, and the records of your own destructive decisions.
