Composio

Composio is a developer platform that gives AI agents secure access to more than 1,500 apps. It sits between an AI client or agent and the applications it needs to act on, handling tool discovery, authentication and execution so that an assistant can move from conversation to carrying out tasks. It is used by developers building agents and by teams deploying them. The vendor lists SDKs, tool execution and auth infrastructure, a command line tool for adding tools and authentication to a coding agent, and a managed MCP gateway offering one endpoint for all tools and agents. It works with Claude, ChatGPT, Codex, Cursor, LangGraph, the Vercel AI SDK and custom harnesses. Features described include searching the tool catalog and loading only the actions a task needs, managed OAuth flows with granular scopes per connected account, triggers that deliver events from connected apps to a webhook, and sandboxed execution. An Enterprise tier adds SSO, SCIM, customer managed keys and audit controls. Pricing is published. The Hobby plan is $0 with no credit card and includes 100,000 tool calls, 50,000 triggers and 3 team members each month. Pro is $29 per month, includes a $29 monthly usage credit that does not roll over, and adds unlimited team members and spend controls. Beyond included amounts, usage is billed per call, and several add ons are priced separately. Enterprise pricing is custom and arranged through a demo.
