Composio is a developer-first tool integration platform that connects AI agents to over 250 pre-built integrations across 900+ SaaS applications. It handles the hardest parts of agent-tool interaction — managed authentication (OAuth, API keys), action execution, error handling, and observability — so developers can focus on agent logic. Compatible with OpenAI, LangChain, CrewAI, AutoGen, and LlamaIndex, Composio provides a unified API and MCP gateway for production-grade agent tooling.

Composio's architecture is built on three pillars:

• Tool Catalog — A repository of 10,000+ pre-built, agent-optimized actions across 250+ toolkits (GitHub, Slack, Gmail, Salesforce, Jira, etc.). Actions are curated for LLM consumption with clear descriptions and parameter schemas.
• Unified API / MCP Gateway — A standardized interface that exposes tools via REST API or Model Context Protocol (MCP). Agents fetch available tools by toolkit name and execute actions through a single endpoint.
• AgentAuth — Managed authentication service that handles per-user OAuth flows, token refresh, and credential storage. Entity IDs link executions to specific user credentials, enabling secure multi-tenant deployments.

Composio's AgentAuth eliminates the need to build OAuth flows. Connect apps through the Composio dashboard or API, and the platform manages:

• OAuth 2.0 authorization code flows
• Token refresh and rotation
• Per-user credential isolation via entity IDs
• Support for API keys, bearer tokens, and custom auth schemes

Execute any tool action with a single API call:

• client.actions.execute() for direct programmatic access
• Framework-specific tool providers for seamless agent integration
• Built-in error handling, retries, and rate limiting
• Execution logging and observability dashboard

Composio integrates with all major agent frameworks:

Entities (via entity_id) tie tools and credentials to specific users:

• Each user gets isolated OAuth connections
• Multi-agent systems can operate on behalf of different users
• Audit trails track which entity performed each action

Event-driven triggers listen for changes in connected apps:

• New GitHub issue, Slack message, or email arrival
• Trigger agent workflows automatically
• Webhook-based real-time notifications
