What Composio does
Composio is an integration and authentication layer for AI agents. It provides more than 1,500 application toolkits, managed OAuth, triggers, tool calls, custom tools, sessions, and an MCP Gateway. Its differentiator is identity-aware execution: a product can connect each user to approved apps while Composio brokers scoped actions without exposing raw third-party credentials to the agent. This removes OAuth, refresh-token, schema, and connector maintenance, but makes Composio part of the product's security and availability boundary.
