Composio

Composio gives your AI agents 1000+ pre-authenticated toolkits, per-user sessions, authentication, triggers, and a sandbox, so you can ship agents that turn intent into action.

This is the Composio SDK monorepo. It contains:

• @composio/core: TypeScript SDK
• composio: Python SDK
• composio CLI: search, execute, and script tools from your shell
• Provider adapters for OpenAI Agents, Claude Agent SDK, Vercel AI SDK, LangChain, and more

Quickstart

Create a session for a user, hand its tools to your agent, and let the agent take action across 1000+ apps. Grab a COMPOSIO_API_KEY from the dashboard first.

TypeScript

npm install @composio/core @composio/openai-agents @openai/agents

@composio/core intentionally packages its TypeScript source and SDK docs so the installed package is inspectable to coding agents. If you want a smaller install with the same API, use @composio/slim.

import { Composio } from "@composio/core";
import { OpenAIAgentsProvider } from "@composio/openai-agents";
import { Agent, run } from "@openai/agents";

const composio = new Composio({ provider: new OpenAIAgentsProvider() });

// Each session is scoped to one of your users
const session = await composio.create("user_123");
const tools = await session.tools();

const agent = new Agent({
  name: "Personal Assistant",
  instructions: "You are a helpful assistant. Use Composio tools to take action.",
  tools,
});

const result = await run(agent, "Summarize my emails from today");
console.log(result.finalOutput);

Python

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())

# Each session is scoped to one of your users
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)

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 it with composio.use() across turns. See what a session is and configuring sessions for restricting toolkits, auth configs, and connected accounts.

Prefer MCP? Every session also exposes a hosted MCP endpoint. Pass mcp: true to composio.create() and point Claude, Cursor, or any MCP client at session.mcp.url. See sessions via MCP.

CLI

The composio CLI runs Composio from your shell and gives coding agents like Claude Code a local tool surface.

curl -fsSL https://composio.dev/install | sh

The installer puts composio on your PATH for future terminals. Open a new terminal, then run composio login. See INSTALL.md for shell setup overrides, including COMPOSIO_INSTALL_SHELL=none for install-only runs.

Use composio search to find tools, composio execute to run them, composio link to connect accounts, and composio run to script workflows in TypeScript. See the CLI docs.

Providers

A provider adapts Composio tools to your agent framework's native tool format:

| Provider | TypeScript | Python | |----------|:----------:|:------:| | OpenAI | @composio/openai | composio-openai | | OpenAI Agents | @composio/openai-agents | composio-openai-agents | | Anthropic | @composio/anthropic | composio-anthropic | | Claude Agent SDK | @composio/claude-agent-sdk | composio-claude-agent-sdk | | Vercel AI SDK | @composio/vercel | — | | Google GenAI | @composio/google | composio-gemini, composio-google | | Google ADK | — | composio-google-adk | | LangChain | @composio/langchain | composio-langchain | | LangGraph | via @composio/langchain | composio-langgraph | | LlamaIndex | @composio/llamaindex | composio-llamaindex | | Mastra | @composio/mastra | — | | Pi | @composio/experimental* | — | | Cloudflare Workers AI | @composio/cloudflare | — | | CrewAI | — | composio-crewai | | AutoGen | — | composio-autogen |

* The Pi provider is experimental and ships from @composio/experimental.

Don't see your framework? Build a custom provider, or skip providers entirely and connect over MCP.
