Composio — 250+ Tool Integrations for AI Agents

What is Composio?

Composio provides plug-and-play tool integrations for AI agents. It automatically handles OAuth authentication, rate limiting, and action execution so agents can focus on reasoning.

In one sentence: Composio connects 250+ tools (GitHub, Slack, Gmail, and more) to AI agents with managed authentication and natural-language actions.

Core Features

Automatically handles OAuth2, API keys, and JWT.

2. Framework Integration

Supports LangChain, CrewAI, Autogen, OpenAI, and other major frameworks.

3. MCP Server Mode

Can be exposed as an MCP server to Claude Code and similar tools.

4. Natural-Language Lookup

Describe needs in natural language and get matched to available actions automatically.

FAQ

Q: Is it free? A: Free tier includes 1,000 actions per month; paid plans scale higher.

Q: How is it different from Zapier? A: Composio is agent-native — tools are exposed to LLMs as function calls, not as human-triggered workflows.
