Thousands of OAuth App Connections
Connect Gmail, Slack, Notion, HubSpot, Salesforce, Jira, GitHub, Asana, Trello, Google Sheets, and hundreds more with a single click. Each connection uses OAuth for secure, scoped access without sharing passwords.
Connect Everything Your Team Uses
Your AI employees work inside the same tools your team already uses. No copy-pasting, no tab switching.
Sistava connects to thousands of apps through OAuth, MCP servers, A2A agents, and custom API endpoints. Your AI employees read from your CRM, write to your project management tool, send messages in your team chat, and update your spreadsheets. All without you building a single integration.
Overview
AI employees are only as useful as the tools they access. Sistava treats integrations as a first-class capability, not an afterthought. Every AI employee connects to your existing tools through four integration types: OAuth apps, MCP servers, A2A agents, and custom API endpoints.
OAuth apps provide the broadest coverage with thousands of pre-built connections to popular SaaS tools. MCP servers expose specialized tool capabilities through a standardized protocol. A2A agents enable collaboration with other AI systems. Custom API endpoints let you connect any internal or external service.
Each integration type is designed for a different use case, but they all work the same way from the AI employee perspective. The employee describes what it needs to do, and the platform routes the action to the right tool through the right protocol.
Before / After
- Before: Your team uses 12 different tools. Information lives in Notion, tasks in Jira, conversations in Slack, contacts in HubSpot. Keeping everything in sync requires manual copy-paste across tabs.
After: Your AI employee reads from all 12 tools and writes back to them. Ask it to "update the project status in Jira based on the latest Slack thread" and it does it in one step. - Before: Every new AI tool promises integrations but delivers 5-10 basic connectors. The one app you actually need is never on the list. Building custom integrations takes weeks of engineering time.
After: thousands of pre-built OAuth app connections cover Gmail, Slack, Notion, HubSpot, Salesforce, Jira, GitHub, and hundreds more. For custom tools, point to any API endpoint or MCP server. - Before: Integrations break when APIs change, tokens expire, or rate limits hit. You find out when a critical workflow silently stops working and nobody notices for days.
After: OAuth tokens refresh automatically. API errors surface as notifications. Connection health is monitored continuously. You know within minutes when something needs attention. - Before: Setting up API integrations means managing client IDs, redirect URIs, scopes, token storage, and refresh flows. Each app has its own OAuth quirks.
After: One-click OAuth connects your apps. Click "Connect," authorize in the provider window, and the AI employee has access. Token management is handled automatically.
Benefits
MCP Server Support
Connect any tool that implements the Model Context Protocol. Your AI employees discover available tools, understand their parameters, and use them correctly. Add internal databases, custom APIs, or third-party MCP servers by URL.
A2A Agent Connections
Connect your AI employees to other AI agents across your organization or partner companies. A2A protocol handles capability discovery, task negotiation, and result delivery between agents from different platforms.
Custom API Endpoints
Connect any REST API by specifying the endpoint URL, authentication method, and request format. Your AI employee calls internal microservices, partner APIs, or legacy systems that do not have pre-built connectors.
Automatic Token Management
OAuth tokens refresh automatically before expiration. Connection health is monitored continuously. Failed connections surface as notifications so you can re-authorize without debugging expired tokens.
Scoped Permissions
Each connection requests only the permissions the AI employee needs. A Slack connection for reading messages does not get write access. Permissions are visible in the dashboard and adjustable at any time.
How It Works
- Choose Your Integration Type — Browse the app marketplace for OAuth connections, add MCP server URLs for tool protocols, or configure custom API endpoints for internal services. Each type has a guided setup flow.
- Authorize Access — For OAuth apps, click "Connect" and authorize through the provider's login screen. For MCP servers, paste the server URL. For custom APIs, provide the endpoint, authentication method, and any required headers.
- Assign to Employees — Connected tools appear in your tool library. Assign them to specific employees or make them available to your entire team. Employees discover new tools and use them when relevant tasks come up.
- Monitor and Manage — Track which employees use which tools, how often, and for what purposes. Revoke access, re-authorize expired connections, or adjust permissions from a central dashboard.
Comparison
| Dimension | Traditional | With Sista |
|---|---|---|
| Number of available integrations | 10-50 pre-built connectors. Everything else requires custom development | thousands of OAuth apps, unlimited MCP servers, unlimited custom API endpoints |
| Setup time per integration | 2-4 weeks for custom API integration including auth, error handling, and testing | 30 seconds for OAuth apps. 2 minutes for MCP servers and custom endpoints |
| Token and auth management | Build custom token storage, refresh flows, and expiration handling for each provider | Automatic token refresh, connection health monitoring, and expiration alerts |
| Adding internal tools | Build a custom adapter layer, document the API, write error handling, maintain versioning | Point to your API endpoint or MCP server URL. The AI employee reads the schema and starts using it |
| Cross-platform data flow | Build ETL pipelines or use Zapier/Make with per-step pricing and execution limits | AI employee reads from one tool and writes to another naturally. No pipeline configuration needed |
| Maintenance | Monitor each integration separately. API changes break workflows silently | Centralized connection health dashboard. Alerts when connections need attention |
FAQ
Which apps can Sistava connect to?
Thousands of apps including Gmail, Google Sheets, Slack, Notion, HubSpot, Salesforce, Jira, GitHub, Asana, Trello, Zendesk, Intercom, Stripe, QuickBooks, and many more. The full list is available in the app marketplace. If your app is not listed, you can connect it through a custom API endpoint or MCP server.
How does OAuth work with AI employees?
When you connect an OAuth app, you authorize Sistava to access your account through the provider's standard login screen. The AI employee receives scoped access tokens that let it perform specific actions. Tokens refresh automatically. You can revoke access at any time from the dashboard or from the provider's settings.
Can I connect internal company tools that are not public SaaS apps?
Yes. Use custom API endpoints to connect any REST API, whether it is an internal microservice, a partner API, or a legacy system. For more advanced tool integration, set up an MCP server that exposes your internal tools through the standardized Model Context Protocol.
Is my data shared between connected apps?
No. Each connection is scoped to the specific AI employee and workspace that authorized it. Data accessed through one connection is not shared with other connections or workspaces. Your AI employee processes data in context but does not store or replicate it across services.
What happens if an integration connection breaks?
The platform monitors connection health continuously. If a token expires or an API becomes unreachable, you receive a notification. The AI employee gracefully handles the missing tool by informing you that a specific connection needs re-authorization rather than failing silently.
Can different employees have different app connections?
Yes. Each employee has its own set of connected tools. Your sales employee might have HubSpot and Gmail connected, while your engineering employee has GitHub and Jira. You control which tools each employee accesses from their individual settings.
