composio-openai

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 on this page — 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

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.
