# composio-openai — Use Composio to get an array of tools with your OpenAI Function Call.

License: permissive · Maintenance: active · Downloads: 98.0K/mo

## What it is and what it does

composio-openai is a provider adapter that connects Composio's tool catalog to OpenAI's function calling interface. It exports two providers: OpenAIResponsesProvider for the Responses API and OpenAIProvider for Chat Completions. Both operate in a non-agentic loop: the model returns tool calls, you execute them via handle_tool_calls, and feed results back to the API until the model responds with text.

The package handles the translation between Composio's tool definitions and OpenAI's function-calling schema, managing session state and tool execution across multiple API rounds. It depends on openai and composio at runtime, requiring both an OpenAI API key and a Composio API key for operation.

Use it for:

- Build an LLM agent that sends emails, manages calendars, or performs other SaaS actions by routing OpenAI function calls through Composio's integration library.
- Implement a multi-turn conversation where an LLM autonomously decides which tools to invoke and processes their results without manual intervention.
- Prototype rapid integrations between OpenAI's chat models and third-party APIs by leveraging Composio's pre-built tool connectors.
- Create a customer support bot that uses OpenAI to understand intent and Composio tools to fetch account data, create tickets, or send notifications.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Bridges Composio's tool ecosystem to OpenAI's function calling APIs, enabling LLM-driven tool execution through both the Responses API and Chat Completions.

Yes. The package is actively maintained, has low install friction, carries a permissive license, and solves a clear integration problem—connecting OpenAI function calling to Composio's tool ecosystem. It has no known vulnerabilities. Install if you need to route OpenAI function calls through Composio's integrations.

## Install

pip install composio-openai
uv add composio-openai
poetry add composio-openai

## Installing composio-openai

Before you install: Low install friction with a pure-Python wheel. Actively maintained—last commit 2026-08-14, released 2026-08-11—and backed by a well-starred repository. Requires Python 3.10 or later.

License in practice: Licensed under Apache Software License (permissive), imposing no significant restrictions on use or redistribution.

Quickstart:

pip install composio composio-openai openai

from composio_openai import OpenAIResponsesProvider
from composio import Composio
from openai import OpenAI

composio = Composio(provider=OpenAIResponsesProvider())
client = OpenAI()
session = composio.create(user_id="user_123")
tools = session.tools()
response = client.responses.create(model="gpt-5.2", tools=tools, input=[...])

Requires COMPOSIO_API_KEY and OPENAI_API_KEY environment variables to be set.

Verify before relying:

- Whether the package supports OpenAI models other than those mentioned in the quickstart example.
- Performance characteristics when handling large numbers of concurrent tool calls.
- Compatibility guarantees with future OpenAI API versions.
