Composio.

Composio is one Connectors that holds all your other tool connections in one place. You connect every tool into Composio once, then plug Composio as a single connector into whatever agent you're using.

What matters is the moment you switch agents. Move from Claude to Codex to your own agent and normally you'd rewire fifty different MCP (Model Context Protocol) every time. With Composio you connect your toolset once and carry it across. One plug instead of fifty.

That's what lets you build Model-agnostic. Your tools stop being tied to any one agent, so swapping the agent underneath doesn't cost you your setup.
