MCP Security and Tool-Space Governance
Securing AI systems as they connect to tools, data, protocols, and operational environments.
Abstract
Tool-using AI systems create a new governance surface. Every connector, server, namespace, capability, and execution path becomes part of the trust boundary. MCP-style ecosystems make this issue urgent because they make tool access easier, richer, and more portable.
Security Thesis
The goal is not to reject rich tool ecosystems. The goal is to keep them legible and governable as they grow. This paper argues for tool identity, risk-tiered registries, least privilege, policy mediation, isolated execution, post-execution verification, and traceable tool outcomes.
Design ruleModels should not inherit broad tool authority simply because a tool exists.
