Composio

What it does

Composio gives AI agents pre-authenticated toolkits, per-user sessions, authentication, triggers, and a sandbox so agents can turn intent into action. The GitHub monorepo describes 1000+ toolkits, tool search, context management, authentication, and a sandboxed workbench. The docs site frames the current product as tools, managed authentication, and secure execution across 1,500+ apps, with smart tool search that surfaces tools by intent and scope at the right time.

The core unit is a session scoped to one of your users. A session loads meta tools that discover, authenticate, and execute app tools at runtime, so the agent does not need hundreds of tool definitions in context. Sessions can be restricted by toolkits, tools, auth configs, and connected accounts, stored and reused across turns, and exposed through a hosted MCP endpoint when you want Claude, Cursor, or another MCP client to connect. Provider adapters translate Composio tools into native formats for OpenAI Agents, Anthropic, Claude Agent SDK, Vercel AI SDK, LangChain, LlamaIndex, CrewAI, AutoGen, and other frameworks listed in the repo.

Composio is an SDK plus hosted platform, not a sandbox computer. Its sandbox is a workbench for running tool backed code with connected accounts, alongside triggers that subscribe to events from connected apps and route them to an agent. Pricing starts free with included monthly tool calls and triggers, then moves to usage based Pro and custom Enterprise terms, with separate handling for Composio-managed apps, direct execution, proxy execution, sandbox execution, and Instant Tools from third party providers.

Verified capabilities

Quick start

Create a Composio session in Python

Install the Python SDK, set your Composio API key, create a session for one user, and get OpenAI-format tools by default. This is a shortened version of the PyPI quickstart with placeholder user text.

pip install composio

from composio import Composio

composio = Composio()
session = composio.create(user_id="user_123")
tools = session.tools()
print(tools)

Source: https://pypi.org/project/composio/. Examples use placeholders only. Never paste a real key into a profile, config file you share, or a ticket.

MCP support: Composio has a documented hosted MCP path. Every session can expose a hosted MCP endpoint when created with MCP enabled, and the docs link to sessions via MCP and connecting over MCP from clients such as Cursor.

Works with

Only sourced support is listed. A missing framework means AgentsUse has not verified it yet, not that it cannot work.

Pricing and license

Free Hobby tier with included monthly tool calls, triggers, and team members, then usage based Pro with a monthly usage credit and custom Enterprise terms. Composio-managed apps, Instant Tools, and some execution modes are priced separately on the pricing page. See the pricing URL for current rates.

Limitations and safety

• The free tier is an included allowance, not unlimited use. Past the included amounts, tool calls, triggers, managed app usage, and Instant Tools can bill separately by mode.
• Composio-managed apps have lower allowances and count toward free tier limits on the pricing page, which advises using your own OAuth app for scaling.
• The platform is hosted and session centric. Teams wanting a fully self-hosted integration runtime or raw sandbox computers will find the model opinionated.
