Composio

Composio is an agent development platform that equips AI agents with tools, managed authentication, and secure sandboxed execution across over 1,500 apps.

Composio enables developers to build and operate production AI agents by connecting them to external software and services. It provides access to tools across more than 1,500 apps, using smart search to resolve and surface relevant tools just in time based on agent intent. The platform manages end-user authentication, including OAuth, API keys, and scoped tokens that refresh automatically. It also includes an execution sandbox pre-wired with connected accounts and tools to run arbitrary code securely. Developers can integrate Composio into their apps via an SDK, use it via a CLI, or expose sessions through hosted Model Context Protocol (MCP) endpoints. It supports frameworks such as OpenAI, Anthropic, and Vercel AI SDK, as well as tools like Cursor, Codex, and Claude Code.
