Composio¶

What it is¶

Composio is a tool integration platform that connects AI agents to over 250+ external applications and services. It provides a unified way to handle authentication (OAuth, API Keys) and tool execution across different LLM frameworks.

What problem it solves¶

Connecting agents to real-world tools usually requires writing boilerplate for authentication and API calls. Composio abstracts this away, allowing agents to "login" to services like GitHub, Google Calendar, or Slack with minimal effort.

Where it fits in the stack¶

[Tool / Infrastructure / Middleware] - It acts as the "hands" for an agent, providing a standard interface to external APIs.

Typical use cases¶

Agents that need to manage GitHub issues or repositories
Personal assistants that interact with Google Calendar or Gmail
Customer support bots that check Jira or Slack

Strengths¶

Massive Library: 250+ pre-built integrations.
Managed Auth: Handles complex OAuth flows and token refreshes automatically.
Framework Agnostic: Works with OpenAI, LangChain, CrewAI, Autogen, and more.
Observability: Detailed logs of every tool call and its output.

Limitations¶

External Dependency: Relies on Composio's platform for managing connections (unless self-hosted).
Privacy: Tool calls go through Composio's infrastructure.

When to use it¶

When you need to connect an agent to multiple SaaS tools quickly.
To avoid building and maintaining your own OAuth integration logic.

When not to use it¶

For simple agents that don't need external tool access.
If you have strict privacy requirements that forbid third-party tool routers.

CLI examples¶

# Login to Composio
composio login

# Add an integration (e.g., GitHub)
composio add github

# List all active integrations
composio list

Getting started¶

Installation¶

pip install composio-core composio-openai

Working Example¶

from composio_openai import ComposioToolSet, App
from openai import OpenAI

# 1. Initialize OpenAI client and Composio Toolset
client = OpenAI(api_key="YOUR_OPENAI_KEY")
toolset = ComposioToolSet(api_key="YOUR_COMPOSIO_KEY")

# 2. Get tools for a specific app (e.g., GitHub)
tools = toolset.get_tools(apps=[App.GITHUB])

# 3. Create an agentic completion request
response = client.chat.completions.create(
    model="gpt-4o",
    messages=[{"role": "user", "content": "Star the repository 'composiohq/composio' on GitHub"}],
    tools=tools,
    tool_choice="auto"
)

# 4. Execute the tool call
result = toolset.handle_tool_calls(response)
print(result)

Licensing and cost¶

Open Source: The SDK is open source.
Cost: Freemium (Free tier available, paid for higher usage/enterprise features).
Self-hostable: Enterprise versions support self-hosting.
