One-click OAuth
Click connect, authorize through OAuth, and your AI employee can immediately read and write to that tool. No API keys to manage, no webhook URLs to paste. The connection is live the moment you approve it.
Things they connect to
1,000+ tools. One click to connect.
Connect your AI agents to Gmail, Slack, Notion, Jira, HubSpot, and thousands more apps with one-click OAuth. Extend their reach with MCP servers and A2A agents for AI-to-AI interoperability, or call any REST or GraphQL API directly. Each connection is scoped per employee.
AI employees that cannot access your tools are just chatbots. With one-click OAuth connections to thousands of apps, MCP servers and A2A agents for AI interoperability, and custom APIs for everything else, your employee connects to your entire stack.
Connections are scoped per employee and controllable per action. Each employee gets only the access it needs.
The result is an employee that works inside your stack, not beside it.
Connecting an app takes a couple of minutes and you only do it once. You pick the app, sign in through the same authorization screen that app already shows you, and approve the access. From that moment your AI employee can read and write inside the tool as a normal part of doing its work. Nothing changes for the humans who use that app every day, and there are no keys to generate or configuration files to edit.
Access is layered so it stays understandable as your workforce grows. The authorization itself sits at the workspace level, each team decides which tools its members inherit, and any single employee can be granted or denied a tool as a deliberate exception. Hire someone new onto a team and they inherit what that team already holds, so you are not repeating setup for every hire. A support employee gets the help desk, a sales employee gets the CRM, and neither quietly picks up the other's access.
Every connected tool has a brake on it. You choose whether it acts on its own or stops and asks you first, and when it asks, the work waits and shows you exactly what it intends to do before anything leaves your account. Switch a tool off for one employee, off for a whole team, or revoke the connection entirely, and your employee simply stops reaching for it. Your employees can ask you to connect something, but taking a connection away stays an administrator decision.
The catalog covers the everyday stack: email, calendars, CRMs, help desks, project trackers, spreadsheets, cloud storage, design tools and publishing platforms. When the thing you depend on is not in there, you still have doors. Point an employee at an MCP server and it discovers whatever tools that server offers. Connect an external agent over the A2A protocol and your employee can hand work across to it. Register a webhook and your employee can fire it in the middle of a task.

Benefits
Protocol support
Connect to any MCP server and your agent discovers new tools automatically. A2A protocol support lets your employees collaborate with external AI agents across platforms and vendors.
Any API
Define the endpoint URL, HTTP method, headers, and auth once. Your AI employee calls it whenever the task requires it. Internal tools, legacy systems, custom microservices, anything with an API.
How It Works
Your AI agents connect to 900-plus apps via OAuth, external AI agents via A2A, MCP servers, and your own APIs so they can take real action in your systems.
Connect Gmail, Salesforce, Notion, HubSpot, Jira, and hundreds more with OAuth in a few clicks. Once connected, your AI employee can read data, create records, send messages, and trigger workflows inside those tools without any code from you. Each connection is scoped to the employee who needs it, so a sales agent gets CRM access and a support agent gets ticketing access.
For more advanced integrations, connect an MCP server to give your AI agent access to internal tools, or define a custom API endpoint so the agent can call your own backend. A2A (agent-to-agent) connections let your AI employees collaborate with external AI agents outside your workforce, opening up automation possibilities that go well beyond a single platform.
You are never left guessing whether a connection worked. When an authorization completes, expires or fails, the result is posted straight back into the conversation where you asked for it. From there the activity feed shows which tool was used, what it was asked to do and what came back, so a connected app is a step you can inspect rather than a black box you have to trust. You can also just ask an employee in chat to connect a tool and it will walk you through it.
Use Cases
Connect to 1,000+ apps with one OAuth flow
Link Gmail, Notion, HubSpot, Airtable, and hundreds of other tools. Your AI employee reads, writes, and acts across your entire stack without you building any integrations.
Plug in an MCP server for specialized tools
Expose any internal tool or data source via an MCP server. Your AI employee discovers and uses those tools the same way it uses built-in ones.
Connect agents across teams with A2A
Use the Agent-to-Agent protocol to let your AI employees call other agents. A leader delegates to a specialist on another team, gets a result, and continues the task.
Hit your internal APIs directly
Register an API endpoint and let your AI employee call it mid-task. Pull live inventory, submit orders, or update records without copying data manually.
FAQ
Does Sistava work with the software my business already runs on?
Sistava connects to more than 1,000 apps, covering the tools most small businesses live in: Gmail, Slack, Notion, HubSpot, Salesforce, Jira, Google Drive, Airtable, Trello, Asana, GitHub, Zendesk and hundreds more. You authorize an app once and your AI employee can work inside it from then on. If something you depend on is not in the catalog, you can still reach it through an MCP server, an external A2A agent, or a webhook.
Do I need a developer to connect my apps?
No developer is needed for the app catalog. Connecting is a click, a normal sign in screen, and an approval, exactly like linking any other service to your account. There is nothing to generate, nothing to paste and nothing to deploy. The more advanced routes, such as pointing an employee at an MCP server or registering your own webhook, are the only places where a technical person helps.
Is it safe to let an AI employee into my inbox and my customer records?
Connections are granted per app and per employee, so an employee can only touch what you explicitly connected for it. Credentials are held and refreshed by the platform rather than pasted into a conversation, and connecting your email to one employee does not hand it to the rest of your workforce. You can also require your approval before a tool acts, and revoking a connection stops that employee using it straight away.
Can I make an AI employee check with me before it does anything in a connected app?
Yes. Every connected tool carries an approval setting: let it act on its own, or make it stop and ask first. With asking turned on, the employee prepares the action and shows you exactly what it wants to do before anything leaves your account, and you approve or decline it in the conversation. You can flip a tool between the two modes at any time, so a risky app can ask while a harmless one runs freely.
What happens to my connections when I hire another AI employee?
New hires inherit the connections their team already holds, so a second employee on your sales team can use the CRM from its first day without you repeating the setup. If you would rather that particular employee not have a tool, you deny it for them alone and nobody else is affected. The reverse works too, so you can give one employee something the rest of the team does not have.
How do I take an app away from an AI employee?
Removing access takes one action and applies immediately. You can switch a tool off for a single employee or a whole team, which leaves the authorization in place for everyone else, or revoke the connection completely so no employee can reach that app. Employees are able to ask you to connect something, but removing a connection is reserved for an administrator.
What if the tool I need is not in the app catalog?
MCP servers, A2A agents and webhooks cover the rest. An MCP server lets your employee discover and use tools you host yourself, which is how most internal and niche systems get in. The A2A protocol connects your employee to an outside AI agent so work can be handed across between them. A webhook turns an endpoint you already have into something your employee can trigger while it works.
How long before an AI employee is actually working inside my systems?
There is no integration project to schedule. Each app is a sign in and an approval, so most people connect their first few tools in the same sitting they hire in. You do not need to connect everything up front either. Start with the one or two tools the job genuinely needs, then add more as the work asks for them, and the same employee grows more capable without any change to how you manage it.
Connected To Everything You Use
An AI employee that can only chat is a chatbot. An AI employee that can read your CRM, update your project tracker, send emails, and call your internal API is an actual team member. Connections are what turn an AI agent from a conversation interface into a working part of your operations.
As you add more connections, your AI employees get more capable without any change to how you manage them. The same agent that answered questions last week can now create invoices, update customer records, and trigger Zapier workflows this week. You add connections when you need them and revoke them when you don't.
How It Works
- Connect Your Apps With OAuth: Authorize 900-plus apps in a few clicks. Your AI agent gets scoped access and starts acting inside those tools immediately.
- Add MCP Or Custom APIs: Connect internal tools via an MCP server or point the agent at your own API endpoints for full custom integration.
- Link External AI Agents: Use A2A connections to let your AI employees collaborate with external agents and extend automation beyond your own workforce.
Our agent now pulls data from Salesforce, creates tasks in Asana, and sends Slack updates, all in a single workflow I set up in an afternoon.
Features in Integrations
- 1,000+ App Integrations: Connect your AI employee to Gmail, Slack, Notion, HubSpot, and over a thousand other apps through secure OAuth, no API keys required. Authorize an app once for your company, then switch it on for any employee with one click. Your employee takes real action inside these apps, sending the Slack message, updating the HubSpot record, drafting the Gmail reply, instead of just describing what it would do.
- E-commerce Management: Manage a Shopify store with an AI employee that reviews catalog, inventory, orders, and market evidence, then asks you before every live store change. Other e-commerce connections are catalog-listed and stay review-first while their provider actions are verified.
- Give Your Employee Any MCP Server: Paste the URL of any external MCP (Model Context Protocol) server into an employee's Tools tab, and Sistava discovers every tool it offers and hands them to that employee, with no code required. The connection is granted to the employee's whole team, so a database server, an internal API, or a community-built MCP server becomes a tool your team can call by name in every conversation. This is the fastest path to extending an employee past the built-in tool set.
- Give Your Employee an External AI Agent: Point an employee at any external A2A (agent-to-agent) agent's URL and it becomes a tool the employee can call on its own. Sistava fetches the agent's public Agent Card, turns each of its skills into a usable tool automatically, and keeps them refreshed as the remote agent changes. No manual mapping of inputs or outputs required.
- Let Your Employee Trigger Webhooks: Point an employee at any outbound webhook, your own automation, a Zapier or Make scenario, an internal service, anything that accepts an HTTP call, and it becomes a tool the employee can trigger on its own during a task, not something you fire manually from a dashboard.
- Let Your Employee Call Any API: Give an employee a config for any REST or GraphQL endpoint, the method, headers, auth, and the shape of the request and response, and it will become a tool the employee can call during a task. Unlike a one-way webhook trigger, this reads data back: the employee gets a structured response it can reason about and act on, not just a fired event. No code required on your side. This is on the roadmap and is not available yet.
