Integration Infrastructure · Early Access

Integration Layer for Teams That Ship

The APIs your team depends on, turned into typed SDKs, MCP servers, and webhook receivers — standardised across your entire team. Define once. Ship everything.

Define Services Once. Generate Everything Else.

One definition. Developers get a typed SDK. Agents get an MCP server. Event-driven systems get a webhook receiver. Each consumer gets exactly what they need — nothing more, nothing less.

Service Definitions

OpenAPI, GraphQL, Docs URLs, Postman Collections, Internal APIs

Fused

Analyzes, bundles, and monitors for drift

Typed SDKs
Fully owned codebase
MCP Servers
Direct agent connection
Native Webhooks
Events directly to your app

Centralised Integrations.
Consumed your way.

Every service your organisation depends on, defined once and shared across every team. Each artefact is scoped to exactly what that team needs — nothing more. Auth, retries, policies, and drift detection live at the layer. Every artefact inherits them, and stays current when APIs change.

Turn Any API Into A Reusable Service

Start with our growing library of pre-curated services or create your own from OpenAPI specs, GraphQL schemas, Postman collections, or API documentation.

Fused extracts endpoints, authentication methods, webhook configuration, and operational settings to create a reusable service definition that can be used across SDKs, MCP servers, and webhooks.

Internal, partner, and third-party APIs
Reuse services across multiple SDKs
Visual Demo Description: A user pastes an OpenAPI specification into the ingestion field. The system instantly parses it and displays a list of available endpoints. The user selectively checks boxes next to the endpoints they need, ignoring the rest, and clicks Import. The system bundles only those selected endpoints into a new, tailored integration.

SDKs shaped around your business

Pick the endpoints your team actually uses — across any combination of third-party, partner, and internal APIs. Fused bundles them into a single typed SDK with auth, retries, tracing, and error handling built in. No boilerplate. Code your team owns, with no vendor runtime dependency.

Build from the dashboard or our agent friendly fused-cli

No vendor runtime dependencies
TypeScript, and Python supported
Shared Configuration
Visual Demo Description: A developer imports FusedSDK — the generated wrapper class — and renames it at import time to match their business domain. All three services are configured in one constructor call. The SDK handles internal employee onboarding: opening a Jira ticket, provisioning GitHub access, and welcoming the new hire on Slack. Here is the exact code being typed in the demo: // Rename FusedSDK at import to match your business capability import { FusedSDK as OnboardingSDK } from "@acme/onboarding-sdk"; const sdk = new OnboardingSDK({ jira: { token: "jira_..." }, github: { token: "ghp_..." }, slack: { token: "xoxb_..." } }); // 1. Open an onboarding ticket for the new hire const ticket = await sdk.jira.issues.create({ project: "ONBOARD", summary: "Onboard new engineer: Jane Doe", issueType: "Task", assignee: "jane.doe" }); // 2. Provision access to the team repository await sdk.github.repos.addCollaborator({ owner: "acme-corp", repo: "platform", username: "jane-doe-gh", permission: "push" }); // 3. Welcome them to the team await sdk.slack.chat.postMessage({ channel: "#engineering", text: `👋 Welcome Jane! ${ticket.data.key} created and repo access granted.` });

Turn Your SDK Into An MCP Server

Every generated SDK can be compiled into an MCP server with two core capabilities: search_docs and execute_tool.
Agents use semantic search to discover the available methods, parameters, and types in your SDK. They then generate TypeScript that is executed in a secure sandbox using the SDK itself.
Deploy instantly on our cloud or self-host in your own infrastructure. Authentication is supplied by your MCP client, allowing agents to use integrations without direct access to credentials.

Hosted or self-hosted deployment
Authentication Stays Under Your Control
Visual Demo Description: Fused Model Context Protocol (MCP) servers expose two core tools to help you autonomously interact with APIs. 1) 'search_docs': Use this tool first. Pass a query to search the generated SDK documentation. It returns the exact TypeScript method signatures, required parameters, and available properties. 2) 'execute': Use this to run workflows. Pass raw TypeScript code using the FusedSDK SDK. The user will pass the necessary auth keys for the integrated services; use these to instantiate the SDK. The MCP server securely executes your code in a sandboxed VM and returns the console output and final result.

Receive Typed Webhooks Anywhere

Receive webhook events anywhere your code runs. Localhost, serverless functions, corporate networks, and ephemeral environments all work without exposing public ingress.
Fused provisions secure webhook receivers and transforms vendor-specific webhooks into typed application events delivered over outbound WebSocket connections—eliminating webhook infrastructure, authentication, and event routing boilerplate.

Dedicated receiver URL per service
Works in any runtime
Generated event enums and typed payloads
Visual Demo Description: A developer registers a single Fused webhook receiver and attaches typed event listeners for Jira and GitHub. When a Jira onboarding ticket is created, GitHub access is provisioned automatically. When GitHub confirms the member was added, a Slack welcome message is sent. The entire onboarding flow runs event-driven with no polling. Here is the exact code being typed in the demo: // A single receiver handles events across all your bundled services import { FusedSDK as OnboardingSDK, fusedWebhooks, JiraWebhook, GithubWebhook } from "@acme/onboarding-sdk"; const sdk = new OnboardingSDK({ github: { token: "ghp_..." }, slack: { token: "xoxb_..." } }); const receiver = fusedWebhooks.registerReceiver("onboarding", "fused_api_key"); // When a Jira onboarding ticket is created, provision GitHub access receiver.on(JiraWebhook.ISSUE_CREATED, async (event) => { const { issue } = event.body; if (issue.fields.project.key !== "ONBOARD") return; await sdk.github.repos.addCollaborator({ owner: "acme-corp", repo: "platform", username: issue.fields.assignee.accountId, permission: "push" }); }); // When GitHub confirms access, welcome them on Slack receiver.on(GithubWebhook.MEMBER_ADDED, async (event) => { const { member, repository } = event.body; await sdk.slack.chat.postMessage({ channel: "#engineering", text: `👋 ${member.login} now has access to ${repository.name}. Welcome!` }); });
