Composio

Composio is an AI tool-calling and integration platform built by Sampark Inc, a YC W24-backed company, that connects AI agents to over 1,000 external tools and services via its MCP Gateway and function-calling infrastructure. The platform solves the authentication, rate-limiting, and execution reliability problems that arise when AI agents try to take actions in external systems like GitHub, Salesforce, Slack, Gmail, Linear, Notion, and hundreds of others. Rather than requiring developers to build and maintain individual integrations, Composio provides managed, production-grade connections that handle OAuth flows, credential refresh, and error handling automatically. The MCP Gateway product gives AI agents a single standardized endpoint for all tool calls, compatible with Claude, Cursor, Codex, Hermes, and other agent frameworks. The GitHub repository has crossed 28,000 stars, reflecting strong developer adoption. Integration coverage spans 1,000 plus tools across categories including CRM (Salesforce, HubSpot), project management (Linear, Jira, Asana, Notion), communication (Slack, Gmail, Microsoft Teams), code platforms (GitHub, GitLab), storage (Google Drive, Dropbox), and scheduling (Google Calendar, Outlook). Each integration is maintained by Composio including OAuth token refresh, rate limit handling, and schema versioning, eliminating the need for developers to maintain their own integration layer. Named gaps: Composio is a developer-facing platform requiring SDK or CLI integration; there is no no-code interface for non-technical users; enterprise customers must contact sales for SOC 2 documentation since no public trust or security page exists; and Composio does not provide browser automation (Browser Use is the complement for that use case). Pricing verified live on composio.dev/pricing as of June 2026. Usage-based model with four tiers: Totally Free at $0 per month with 20,000 tool calls per month and community support. Ridiculously Cheap at $29 per month with 200,000 tool calls per month, email support, and $0.299 per 1,000 additional calls. Serious Business at $229 per month with 2,000,000 tool calls per month, Slack support for teams generating over 1,000 calls per month, and $0.249 per 1,000 additional calls. Enterprise at custom pricing with dedicated SLA, SOC 2 compliance, custom API volume, and VPC or on-premises deployment. Privacy policy explicitly states that Composio does not use any user data to train AI or machine learning models. Composio is not the right fit for non-technical teams: the platform requires SDK or CLI integration and there is no visual interface for business users; Zapier (from $19.99 per month) and Make (from $9 per month) provide no-code workflow automation for non-developers connecting the same class of SaaS tools. Teams with security procurement requirements that mandate SOC 2 before vendor approval will need to engage Composio sales directly for the Enterprise tier, as no self-serve SOC 2 documentation or public trust center exists. Startups building browser-based automation rather than API-based tool calling should evaluate Browser Use (free open-source) alongside Composio, as the two are complementary: Composio handles API actions while Browser Use handles web interfaces without APIs. Current state Q2 2026: Composio surpassed 28,700 GitHub stars and expanded its positioning from 250 plus integrations to over 1,000 toolkits, reflecting rapid ecosystem growth. The MCP Gateway supports tool search and context management alongside authentication and sandboxed workbench capabilities. The platform now serves agent frameworks including Claude, Codex, OpenClaw, Cursor, and Hermes, reflecting broad adoption across the emerging agent developer ecosystem. G2 presence is early with 7 reviews at 4.9 stars; the primary evidence signal is GitHub adoption rather than review volume. No self-serve SOC 2 documentation is publicly available as of this audit; enterprise security requirements must be addressed through direct sales engagement.
