Google has open-sourced SAM (Sovereign Agent Mesh), an Apache-2.0 zero-config, zero-trust peer-to-peer network designed for autonomous AI agents to share tools securely across diverse environments, including cloud, datacenters, laptops, and mobile devices. Instead of exposing internal scripts or private APIs to the public internet, SAM creates a VPN-like overlay using the Model Context Protocol. Its architecture relies on three binaries and translates OIDC claims into Biscuit tokens for strict offline authorization. A beta public mesh is available, but production deployments require self-hosting the control plane for full data and policy control. Target users include regulated industries and enterprises needing cross-network agent collaboration and fine-grained access governance.
This update represents a notable development in the Ai sector. Organizations and founders tracking this space should evaluate potential strategic and technical implications on their operations.
