Composio is a developer platform for building AI agents that can take actions across external applications and services. It provides access to 1,000+ integrations, allowing agents to work with apps such as GitHub, Slack, Gmail, Notion, Linear, Salesforce, and many others. Developers can use Composio to discover the right tools, authenticate users, execute actions, respond to external events through triggers, and run multi-step workflows in secure sandboxed environments. The platform supports MCP and integrates with popular AI frameworks and coding agents, including OpenAI, Anthropic, Vercel AI SDK, Claude Code, Cursor, and other MCP clients. Composio is designed to handle much of the integration and authentication complexity required to turn an AI chatbot into an agent capable of performing real-world tasks. 
