Frequently Asked Questions

How is Composio different from a single MCP server?

A typical MCP server connects to one app, whereas Composio is an aggregator: a single entry point gives your agent 1,000+ app toolkits and handles OAuth, multi-user sessions and triggers for you, so you avoid wiring up servers one by one.

How do I connect Composio to my agent?

Use the npx -y @composio/mcp CLI to set up the MCP connection, or integrate directly via the @composio/core SDK with OpenAI, Anthropic, LangChain and more. You will need an API key from composio.dev on first use.

Is Composio open source and free?

The core SDK and CLI are open source (nearly 30k GitHub stars) with a free tier; the hosted platform charges by usage and advanced features, though individual and small-scale use usually fits within the free tier.
