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.
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.
@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);
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:
The TypeScript SDK is tested against Node 22+; the Python SDK supports Python 3.11+.
Development
mise install # pinned toolchain (Node, Python, pnpm)
pnpm install
pnpm build
pnpm test
Python commands run from python/; see python/README.md. We welcome contributions to both SDKs; read the contribution guidelines before submitting pull requests.
