Keycard Labs

Keycard provides developer-first identity infrastructure designed for AI agents and modern applications. The company focuses on enabling secure access management for AI agents, allowing them to interact with services, tools, and resources across networks and clouds. Their platform addresses the challenge of moving agent-driven workloads into production environments while maintaining security and control. The company recently acquired Runebook to make the Model Context Protocol (MCP) production-ready, demonstrating their commitment to standards-compliant implementations. Keycard's infrastructure enables developers to create and expose agents and tools as secure, remote MCP servers. Their approach centers on cryptographically verifiable credentials tied to real identities, eliminating reliance on static credentials in favor of context-aware, dynamic access controls. The platform serves multiple stakeholders: agent builders receive dynamic tools for adaptive security posture, resource owners gain control over agent access and permissions, end users benefit from transparent operations with audit trails, and security teams get comprehensive visibility and policy enforcement capabilities. Keycard's architecture is built on principles of identity truth, secure-by-design infrastructure, agent evolution anticipation, and dynamic access management. Founded by Matt Creager, Jared Hanson (creator of Passport.js), and Ian Livingstone, the company is backed by investors including a16z, Boldstart, and Acrew Capital, along with individual investors from companies like Auth0, Okta, Anthropic, and Cloudflare.
