Composio

As an AI developer tool, Composio sits in the API layer between your agent and the apps it needs to act on.

Composio is an AI API toolset that connects AI agents and LLMs to 250+ tools, so you spend less time hand-writing each integration.

You can build, connect and deploy integrations for CRM, HRM, ticketing, productivity and accounting systems.

Managed authentication is included, which matters because logging in to a third-party account on an agent's behalf is usually the tedious part of the job.

System tools sit alongside the app integrations.

Composio also lists SOC Type II compliance, a useful detail if your agent will touch company data and your security team starts asking questions.

The audience is engineers building agents, not people looking for a finished assistant, so expect to work in code rather than click through a ready-made app.
