Composio
Composio is an agent execution platform that bridges AI decision-making and real-world action across 1000+ apps through just-in-time tool calls, secure delegated auth, sandboxed environments, an MCP gateway, parallel execution, and context-aware sessions. Developers get managed OAuth, a tool router for runtime tool discovery, webhook triggers, and a CLI so agents turn intent into action without custom integration work.
Composio publishes 38 APIs on the APIs.io network, including Account Management API, AI API, API Keys API, and 35 more. Tagged areas include AI Agents, Authentication, Integrations, MCP, and OAuth.
The Composio catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.
Composio’s developer surface includes changelog, CLI, authentication, developer portal, documentation, getting-started guide, API reference, and 47 more developer resources.
