The backstory
Composio solves the boring blocker in agent building: OAuth. It holds the tokens, refreshes them, and exposes hundreds of applications as tools an agent can call without anyone writing an integration. MCP arguably commoditises the protocol, and Composio embraced it rather than fighting it. What does not commoditise is managed multi-tenant authentication across hundreds of vendors, which is a compliance and operations burden most teams are relieved to outsource.
