Atsign, a pioneer in pre-emptive security and zero-trust connectivity, announced the launch of MCP NoPorts on June 18, 2025. This innovative solution addresses critical security vulnerabilities and deployment challenges enterprises face when integrating AI models and Model Context Protocol (MCP) servers with sensitive data and systems.
Atsign unveils MCP NoPorts for secure AI model and MCP server deployment.
Eliminates open ports, reducing network attack surfaces to zero.
Uses cryptographic identities for zero-trust access, preventing unauthorized use.
Provides end-to-end encrypted connections to safeguard sensitive data.
Accelerates AI deployments by removing IT bottlenecks like firewall setups.
Enables seamless, secure collaboration across global AI systems.
The integration of AI with enterprise systems requires MCP servers to connect AI agents to backend operations, often exposing valuable data to external threats via standard HTTP. MCP NoPorts eliminates this exposure by removing open ports on AI inference nodes, data services, and MCP servers, rendering them invisible to botnets and reconnaissance. “The real power of AI comes from its ability to automate complex processes, but this is constantly undermined by security risks which severely delays deployments,” said Colin Constable, Atsign Co-Founder and CTO.
MCP NoPorts assigns each AI model, tool, or service a unique cryptographic identity, ensuring access only after verification. This zero-trust approach prevents unauthorized access and AI agent impersonation. End-to-end encrypted connections further protect sensitive data, proprietary logic, and AI interactions from eavesdropping and tampering, addressing concerns like data exposure and malicious invocations.
By eliminating the need for complex firewall configurations, static IPs, or VPNs, NoPorts enables developers to deploy AI models and MCP servers in minutes. This removes IT bottlenecks, freeing teams from tedious setups. The solution also supports secure global collaboration, connecting developers and systems without external exposure, enhancing efficiency and scalability.
Traditional network protections are ill-suited for autonomous AI agents. MCP NoPorts fills this gap, offering unparalleled security and speed for enterprise AI initiatives. By making AI infrastructure invisible and securing every interaction, Atsign empowers organizations to harness AI’s full potential without compromising data integrity or deployment timelines.
At Atsign, we believe that people, entities (e.g. AI), and things should connect securely and directly, while always being invisible to bad actors. By eliminating the need for open ports and centralized servers, the atPlatform empowers developers and organizations to build applications with "invisible" security built in, placing data and device control back into the hands of their owners. Atsign is the creator of the atPlatform, the most robust infrastructure available for "invisible networking" and secure, private, peer-to-peer connectivity.
