Composio is an agent tooling and authentication harness developed by ComposioHQ. It provides a managed tool execution infrastructure and command-line interface designed to connect AI coding agents—such as Claude, Codex, Cursor, Hermes, and OpenClaw—to external APIs, developer services, and SaaS applications. In day-to-day operations, developers interact with Composio via its Universal CLI, programming SDKs, or managed Model Context Protocol (MCP) gateway. The platform allows agents to execute actions and listen to triggers across external ecosystems (like Linear, GitHub, Sentry, and Slack) using natural language instructions, with Composio automatically managing OAuth handshakes, API keys, token renewals, and permissions scopes. What distinguishes Composio from standard agent harnesses is its centralized authentication management and turnkey MCP integration layer. Rather than requiring developers to manually build custom API wrappers, manage OAuth redirect endpoints, or script credential storage for each tool, Composio standardizes tool calling and provides automated type generation across hundreds of supported services. Composio provides a free developer platform tier for individuals and offers enterprise tiers featuring single sign-on (SSO), governance guardrails, and audit logging for team-wide agent deployments.
