Composio — 250+ Tool Integrations for AI Agents

What is Composio?

Composio provides plug-and-play tool integrations for AI agents. Instead of building OAuth flows and API wrappers for every service, Composio handles authentication, rate limiting, and action execution — letting agents focus on reasoning.

Answer-Ready: Composio is an integration platform that connects AI agents to 250+ tools (GitHub, Slack, Gmail, Jira, etc.) with managed authentication and natural language action execution.

Key Features

1. Managed Authentication

Composio handles OAuth2, API keys, and JWT for all integrations:

# User connects their GitHub account
composio add github  # Opens browser for OAuth

# Agent uses it seamlessly
tools = toolset.get_tools(actions=[
    Action.GITHUB_CREATE_ISSUE,
    Action.GITHUB_CREATE_PULL_REQUEST,
])

2. Framework Integrations

# LangChain
from composio_langchain import ComposioToolSet
tools = ComposioToolSet().get_tools(apps=["github", "slack"])

# CrewAI
from composio_crewai import ComposioToolSet
tools = ComposioToolSet().get_tools(apps=["jira", "linear"])

# Autogen
from composio_autogen import ComposioToolSet

3. Natural Language Actions

# Find actions by description
actions = toolset.find_actions_by_use_case(
    apps=["slack"],
    use_case="send a message to a channel"
)

4. MCP Server Mode

  "mcpServers": {
    "composio": {
