Composio is infrastructure for AI agents that need to interact with the outside world. Rather than every team building custom authentication flows, rate limiting, and API wrappers for each external service their AI agent needs to use, Composio provides more than a thousand pre-built toolkits that handle this integration work, along with managed authentication and sandboxed execution so agents can call tools safely.
Founded in 2023 and based in San Francisco, Composio positions itself specifically for the agentic AI era, supporting protocols like the Model Context Protocol (MCP) that let AI assistants such as those built on Claude, Cursor, or Windsurf discover and call external tools in a standardized way.
Composio prices its platform based on monthly tool call volume rather than seats or a flat subscription. The Free tier includes 20,000 tool calls per month with community support. The next paid tier, at 29 dollars per month, unlocks 200,000 monthly tool calls with email support, and a higher 229 dollar per month tier provides 2 million monthly tool calls with Slack support.
Usage beyond each tier's included allotment is billed per additional 1,000 tool calls, and organizations with stricter compliance, deployment, or support needs can move to a custom-quoted Enterprise plan that adds SOC 2 support, dedicated accounts, and VPC or on-premises deployment options.
Composio raised a 25 million dollar Series A round in July 2025 led by Lightspeed Venture Partners, with participation from firms including SV Angel, Blitzscaling Ventures, and Operator Partners, alongside existing investors Elevation Capital and Together Fund. Notable individual backers include Vercel CEO Guillermo Rauch and HubSpot co-founder Dharmesh Shah.
The company continued expanding its product surface into 2026, open-sourcing an Agent Orchestrator framework in February 2026 aimed at helping developers build more structured, stateful multi-agent systems rather than relying solely on simple reason-and-act loops.
