Install
Requires Python 3.11 through 3.15.
pip install composio
Quickstart
Create a session for one of your users and hand its tools to your agent:
from composio import Composio
composio = Composio() # reads COMPOSIO_API_KEY, or pass api_key=...
session = composio.create(user_id="user_123")
tools = session.tools() # OpenAI-format tool definitions by default
By default a session gets meta tools that discover, authenticate, and execute app tools at runtime, so you don't load hundreds of tool definitions into context. Store session.session_id and reuse the session across turns:
session = composio.use(session_id)
See how Composio works for sessions and meta tools, and configuring sessions for restricting toolkits, tools, auth_configs, and connected_accounts on composio.create().
Use with an agent framework
Provider packages adapt session.tools() to your framework's native tool format. With OpenAI Agents:
pip install composio composio-openai-agents openai-agents
from composio import Composio
from composio_openai_agents import OpenAIAgentsProvider
from agents import Agent, Runner
composio = Composio(provider=OpenAIAgentsProvider())
session = composio.create(user_id="user_123")
tools = session.tools()
agent = Agent(
name="Personal Assistant",
instructions="You are a helpful assistant. Use Composio tools to take action.",
tools=tools,
)
result = Runner.run_sync(starting_agent=agent, input="Summarize my emails from today")
print(result.final_output)
Other Python providers: composio-openai, composio-anthropic, composio-claude-agent-sdk, composio-langchain, composio-langgraph, composio-llamaindex, composio-crewai, composio-autogen, composio-gemini, composio-google, composio-google-adk. Don't see yours? Build a custom provider.
MCP
Every session also exposes a hosted MCP endpoint. Pass mcp=True and point Claude, Cursor, or any MCP client at it:
from composio import Composio
composio = Composio()
session = composio.create(user_id="user_123", mcp=True)
print(session.mcp.url) # MCP endpoint for this session
print(session.mcp.headers) # auth headers for the endpoint
See sessions via MCP.
Authentication
Sessions manage connections for you by default; the agent walks the user through OAuth with the session's meta tools. To drive the flow yourself, authorize a toolkit from the session:
connection_request = session.authorize("gmail")
print(connection_request.redirect_url) # send the user here to approve access
connection_request.wait_for_connection()
See authentication for auth configs, custom OAuth apps, and connection lifecycle.
Triggers
Subscribe to events from connected apps (new email, new commit, and so on) and react to them:
from composio import Composio
composio = Composio()
trigger = composio.triggers.create(
slug="GITHUB_COMMIT_EVENT",
user_id="user_123",
trigger_config={"owner": "composiohq", "repo": "composio"},
)
subscription = composio.triggers.subscribe()
@subscription.handle(trigger_id=trigger.trigger_id)
def handle_event(data):
print("Event received:", data)
subscription.wait_forever()
subscribe() streams events over a WebSocket for local development. In production, register a webhook URL and parse deliveries with composio.triggers.parse(). See setting up triggers.
Development
This package lives in the Composio SDK monorepo under python/. See the contribution guidelines to get set up.
