Composio is the auth + tool-calling layer for AI agents — 250+ pre-built integrations (Gmail, Slack, GitHub, Notion, HubSpot), OAuth handled for you, metered as tool calls. Free, $29/mo, $229/mo, Enterprise.
Composio is the integration plumbing that lets AI agents actually do work in other people's apps. Instead of every agent team rebuilding OAuth flows for Gmail, Slack, GitHub, Notion, HubSpot, Linear, Jira, Salesforce, and 200+ other SaaS tools — and then re-implementing the function-calling adapter for each LLM SDK — Composio ships a single SDK and a hosted auth layer that exposes those services to your agent as ready-to-call tools. The product runs as an SDK (Python and TypeScript) that plugs into <a href="/tools/langchain">LangChain</a>, <a href="/tools/llamaindex">LlamaIndex</a>, <a href="/tools/crewai">CrewAI</a>, the OpenAI SDK, Anthropic, and Vercel's AI SDK. Pricing is tiered around 'tool calls': Free at $0 for early development; 'Ridiculously Cheap' at $29/month with email support and $0.299 per 1K additional tool calls; 'Serious Business' at $229/month including 2M tool calls/month, Slack support, and $0.249 per 1K overage; and Enterprise on contact sales for custom user accounts, dedicated SLA + SOC-2, custom API volume, and VPC/on-prem deployment.

Solves a real agent bottleneck: securely connecting AI systems to SaaS actions, not just reading context. The main caution: Fetched pages contain agent-directed signup text, so humans should verify signup and procurement flows manually.

Weekly insights on the latest AI tools, features, and trends delivered to your inbox.
Composio has leaned heavily into the 2026 wave of coding agents and MCP adoption. The platform now ships first-class integrations for Claude Code, Cursor, and Codex, giving these coding agents managed authenticated access to GitHub, Linear, Jira, and deployment platforms beyond their native file-editing capabilities. The MCP Gateway — an enterprise feature — lets organizations expose curated Composio toolkits to any MCP-compatible client under centralized governance, enabling IT teams to control which tools are available to which agents. The toolkit catalog has continued to grow past the 1,000 mark with expanded action depth for popular services. Framework support has broadened to include LangGraph and Semantic Kernel alongside existing LangChain, CrewAI, and AutoGen integrations. On the platform side, Composio has added improved observability features, better rate-limit handling across high-volume tool calls, and enhanced sandbox support for code execution use cases with Docker, E2B, and Fly.io runtimes.
