Composio

What is Composio?

Composio is a tool integration platform that lets AI agents discover and use apps on a user's behalf. It is made by Composio and provides a catalogue of toolkits, managed authentication, triggers and session-based tool delivery for frameworks such as OpenAI Agents, Claude Agent SDK, Vercel AI SDK, LangChain and CrewAI. The problem it solves is the integration layer around agents: instead of building and maintaining an OAuth app, token refresh and tool schema for every service, a team connects once and lets the agent call the tools it needs.

Key features

• Large toolkit catalogue. Composio lists more than 1,500 toolkits, covering apps such as Gmail, GitHub, Linear, Notion and Slack.
• Managed authentication. OAuth consent, token storage, refresh and scopes are handled for each connected account, so user credentials stay out of the agent.
• Sessions. A session scopes connections and tool calls to a user ID, and exposes a small set of meta tools instead of loading every schema into the model context.
• Triggers. Events from connected apps can be delivered to a webhook, which lets an agent react to a new email, issue or message.
• Custom tools and MCP. Teams can add their own tools and MCP servers alongside the hosted catalogue, or expose a session as an MCP endpoint.
• Composio Firewall. A policy layer checks tool requests and results against rules before an action runs.

Who is Composio for?

AI product teams building agents that need to act in third-party apps, especially B2B SaaS companies that connect customer accounts. It suits developers who want to avoid maintaining OAuth flows and tool schemas for many services, platform teams that need per-user connection isolation, and automation teams connecting agents to internal and external tools.

Use cases

• Building an assistant that reads email, creates issues and updates a CRM for each user.
• Letting an agent react to a new support ticket or calendar event through triggers.
• Connecting a coding agent to GitHub, Linear or Notion through MCP.
• Applying a policy that blocks risky tool calls before they run.

Pricing

Composio has a Hobby plan at $0 per month with 100,000 tool calls, 50,000 triggers, unlimited connected accounts and three team members. Pro costs $29 per month and includes $29 of monthly usage credit, unlimited team members, higher rate limits, spend controls and add-ons. On Pro, tool calls beyond the included amount cost $0.0003 each for your own app, API key or MCP, and trigger events cost $0.003 each. Enterprise pricing is custom and adds SSO, SCIM, customer-managed keys, a business associate agreement, dedicated support and a service level agreement. See the official Composio pricing page.

Getting started

1. Create an account and generate a COMPOSIO_API_KEY from the dashboard.
2. Install the SDK for your language.
3. Create a session for a user, request its tools and pass them to your agent framework.

pip install composio

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

Alternatives

FAQ

Is Composio free?

Yes. The Hobby plan costs $0 and includes 100,000 tool calls, 50,000 triggers and three team members. Pro costs $29 per month and includes usage credit.

What is Composio used for?

Composio connects AI agents to third-party apps. It handles tool discovery, OAuth connections, triggers and execution so an agent can read email, create issues or update records for a user.

Does Composio support MCP?

Yes. A Composio session can be exposed as an MCP endpoint and used from MCP-compatible clients, and teams can add their own MCP servers alongside the hosted tools.

Composio vs Pipedream?

Pipedream is a workflow automation platform for connecting APIs and running scheduled or event-driven jobs. Composio focuses on giving AI agents tools and per-user authenticated connections at run time. The two can be used together, with Pipedream handling workflows and Composio handling agent tool access.

Composio manages OAuth consent, token storage, refresh and scopes for connected accounts. The agent receives tool access without handling the user's raw credentials.
