Why it matters
extensible-mcp targets a real agentic-AI attack surface by letting defenders gate and filter which MCP tools an AI agent may invoke, constraining tool-abuse and over-broad tool exposure in Model Context Protocol deployments.
extensible-mcp (SenteLabsAI) is an open-source MCP proxy that adds on-demand server loading, searchable tools, and pluggable filters for access control, with a load_control mechanism and structural guarantees over which downstream MCP tools an agent can reach. Its accompanying whitepaper ("Policy as Code, Policy as Type", arXiv:2506.01446) argues for expressing ABAC access-control policies as types in dependently typed languages such as Agda and Lean.
