Composio
A platform that provides tool access and authorization infrastructure for AI agents, officially claiming to connect over 1500 applications, retrieve tools on demand, host OAuth authorizations, and support CLI, MCP gateway, and sandbox execution.
Updated: 2026-10-26
What is Composio?
Composio is a tool access and authorization infrastructure for AI agents. A positioning statement on its official website reads, "Composio sits between your AI and your apps, turning your requests into actions" — it does not build models itself, but instead acts as a bridge between AI agents and the applications you use, transforming "requests in a single sentence" into "actions that are actually executed". According to official documentation, it has integrated over 1,600 applications, while the copy on its homepage states it offers more than 1,500 tools.
Who is it for?
- Application developers who need to connect real SaaS applications to AI agents and require someone to manage OAuth authorization and token refresh for them.
- Teams for internal automation, such as having AI agents query Sentry errors and create Linear issues.
- People who want to directly attach tools to existing programming agents such as Claude, Codex, and Cursor without modifying their original harnesses.
- Product teams focused on multi-tenant isolation, using userIDs to distinguish the connected accounts and execution records of different users.
Key features
6On-demand Tool Retrieval (No Context Bloat)
The official statement is that each action consumes context. Composio will retrieve the full catalog, load only the parts required for the current task, and first provide an execution plan and guardrails.
Managed Authorization (OAuth management)
Consent, token storage, refresh and scopes are all handled by the platform, with granularity configurable separately for each connected account.
One-click Connection
You can connect apps in the backend panel, or the AI can initiate login when needed, with a one-time secure login for each app.
Session Conversation Model
`composio.create(userId)` establishes a session, binding the user, available toolkits, authorization, and execution state together; by default, it equips agents with meta-tools to discover and execute application tools, instead of stuffing hundreds of tool definitions into the context.
Sandbox & Triggers
The standard session has a built-in sandbox for handling files and large responses; Triggers can subscribe to any app events and route them to AI agents.
Multiple access methods
The official platform provides native plugins for Codex / Claude Code, the Composio CLI, and a managed MCP Gateway.
How to use Composio
- The free quota is 100,000 tool calls, 50,000 triggers and 3 team members per month for the Hobby tier on the official pricing page.
- The trial period is long enough to go through the entire process, and then you can evaluate the Pro plan (officially priced at $29/month, including credits for the same quota usage).
- Whether to register your own OAuth application or use the platform-hosted one is a crucial choice: the official documentation states that the OAuth toolkit defaults to using managed apps, and only brings your own applications when you need a custom brand, scopes, or a consent page.
- Always use a stable identifier from the database for the userID.
- the official documentation explicitly advises against using IDs that may change.
- The same user can connect multiple accounts (such as work and personal emails) and choose as needed.
- The more actions an agent can call, the larger the authorization scope.
- Before launch, cross-check the usage limits and billing Q&A in the official FAQ to prevent unexpected bills from the agent.
