Stacklok

Stacklok is an enterprise AI infrastructure company founded in 2023 and headquartered in Seattle, Washington. It provides an open, Kubernetes-native architecture for running and governing AI agents securely, allowing organisations to deploy agents that connect to sensitive internal systems and data while keeping data within the enterprise firewall. The company is venture-backed, with investors including Accel, Bain Capital Ventures and Madrona.

The platform is built on ToolHive, an open-source Model Context Protocol (MCP) platform with contributions across 10 countries, designed to help enterprises avoid vendor lock-in from frontier labs and hyperscalers. Alongside ToolHive, Stacklok develops an MCP Gateway, which secures agent-to-tool actions; an LLM Gateway, which controls agent-to-model interactions; and Mecatl, a cloud-native agent harness. The company reports over 20 million tool calls secured per month.

Technical work spans AI agent infrastructure, Kubernetes, MCP, AI agent security and governance, LLM gateway and model access control, cloud-native architecture and open-source software. The company is founded and led by Craig McLuckie and Joe Beda, co-creators of Kubernetes and founders of the Cloud Native Computing Foundation (CNCF).

Stacklok operates with an open-source-driven culture and an explicit stance against vendor lock-in, with a focus on security, compliance, operational control and self-hosted, privacy-first deployment within customer Kubernetes environments.
