# Things they connect to *Equip them with tools* 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. ## At a Glance - **1,000+** OAuth app integrations - **MCP** AI interoperability protocol - **A2A** Agent-to-agent protocol ## Use Cases ### Connect to thousands of 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. ## Features in this Category - **[Thousands of Connected Apps](/en/features/connections/oauth-apps)** — Connect any of thousands of apps in one click with no API keys to manage and no webhooks to configure. - **[Connect to MCP Servers](/en/features/connections/mcp-servers)** — Connect to any Model Context Protocol server and give your employee new tools instantly. - **[Connect to A2A Agents](/en/features/connections/a2a-agents)** — Connect to external A2A agents so your employee can delegate tasks to other AI agents across the ecosystem. - **[Call Any API](/en/features/connections/api-endpoints)** — Call any REST or GraphQL API to connect your employee to systems that don't have a dedicated integration.
