MCPSaaS is a security tool that provides a managed secure MCP proxy for AI agents. It ensures end-to-end security with transparent message signing, replay protection, and tool integrity verification, requiring zero code changes.
MCPSaaS offers a managed secure MCP proxy service designed to provide zero-trust security for AI agents. It addresses critical vulnerabilities in the Model Context Protocol (MCP) by implementing transparent message signing, replay protection, and tool integrity verification without requiring any code changes to existing MCP servers. The service ensures every action is signed, every tool is gated, and every agent is verified, preventing issues like tool poisoning, rug pulls, and unauthorized operations. MCPSaaS aligns with the MCPS protocol (an IETF Internet-Draft) and the OWASP MCP Top 10 controls, covering risks such as message integrity, agent identity, and supply chain vulnerabilities. It integrates seamlessly with security operations centers (SOC) tools like Microsoft Defender for Cloud, Azure Sentinel, and other SIEMs via syslog, providing real-time alerts and comprehensive audit trails.
Best used for
Ideal for startup founders who need to secure their AI agent deployments, prevent critical vulnerabilities like tool poisoning and replay attacks, and ensure compliance with security standards. Especially valuable for teams integrating AI agents into sensitive operations requiring robust end-to-end security and auditability.
How does MCPSaaS secure existing MCP servers without code changes?
MCPSaaS operates as a proxy. You simply change the MCP endpoint URL in your configuration to point to the MCPSaaS proxy. This transparently adds message signing, replay protection, and tool integrity verification without requiring any modifications to your MCP server's code or an SDK.
What security risks does MCPSaaS specifically address?
MCPSaaS directly addresses critical OWASP MCP Top 10 risks, including tool poisoning (MCP-01), tool rug pulls (MCP-04), insufficient authentication (MCP-07), and lack of message integrity (MCP-08). It also provides partial coverage for other risks like excessive agency and data exfiltration.
Does MCPSaaS support enterprise key management solutions?
Yes, MCPSaaS offers integration with GCP Cloud KMS for enterprise key management. This provides features like ECDSA P-256 key generation in Cloud KMS, Google-managed key storage, automatic key rotation, and SOC2 + FIPS 140-2 Level 1 compliance, including Bring Your Own Key (BYOK) support.
