Composio

Composio is a tool integration platform that gives AI agents secure, authenticated access to more than 1,500 apps so they can take real actions such as sending email, filing issues or updating a CRM. It solves the unglamorous parts of agent building: OAuth for every service, storing tokens safely, picking the right tool among thousands, and logging what the agent did. It works for developers building their own agents and for anyone using an assistant that supports MCP.

What is Composio used for?

Composio is used whenever an agent needs to act in other software on behalf of a user. Common uses include:

• Giving a custom agent tools for Gmail, Slack, GitHub, Notion, HubSpot or Salesforce
• Connecting ChatGPT, Claude, Cursor or another MCP client to business apps
• Handling multiple accounts for the same app, such as several inboxes
• Starting agent runs from app events with triggers
• Requiring approval before risky actions and reviewing a log of every call
• Adding custom tools or existing MCP servers for apps not in the catalog

Who Composio is best for

Composio suits AI engineers and startups building agent products, and power users who want their assistant to work across many apps without writing integrations. Security-minded teams like that tokens are encrypted and actions can be limited. Companies that need a full workflow engine with branching logic and schedules may want an automation platform instead, with Composio as the tool layer.

Composio pricing

As of October 2026, the free Hobby plan includes 100,000 tool calls and 50,000 trigger events a month, 3 team members, unlimited connected accounts and the full toolkit catalog, with usage paused at the cap and no card required. Composio-managed apps have a smaller share of that allowance. Pro costs $29 per month and includes $29 of usage credit, unlimited team members, higher rate limits and metered overage starting at $0.0003 per tool call. Add-ons cover advanced white-labeling, IP allowlists, BAA and zero data retention. Enterprise is custom and adds SSO, SCIM, customer-managed keys and SLAs.

Limitations to keep in mind

• Many security and compliance features are paid add-ons priced per call or per connection
• The pricing page gives two different overage rates for Composio-managed apps, so confirm with support
• Some tools, such as web search and transcription, are billed per call separately
• Agents still need careful prompts and permissions, since broad tool access raises risk

Composio vs alternatives

Zapier AI is the better choice when you want ready-made automations and Zapier's own agent and MCP features with no code. n8n wins for teams that want a self-hosted workflow engine with AI steps and full control of data. Make suits visual scenario design for operations staff. LangChain provides the agent framework itself, and many developers pair it with Composio for authenticated tools. Composio is the pick when the hard problem is giving agents safe, per-user access to a long list of apps.

Tips for getting started with Composio

Start on the Hobby plan with your own OAuth app or API keys, since that keeps the full 100,000-call allowance. Connect only the toolkits your agent needs, which also helps the model choose tools accurately. Turn on approval for actions that send messages or delete data. Review the action log after the first runs to spot unexpected calls.
