MCP, Tool Use, and the New Attack Surface Nobody Is Mapping

Short summary

MCP and agentic systems create unprecedented delegation authority chains that current enterprise governance cannot handle. Four failure states expose how boundaries collapse: scope creep, implicit trust inheritance, non-revocable grants, and chain opacity. The missing discipline is delegation governance — auditable tool inventory and revocable authority control.

• •MCP introduces authority chains longer than enterprise governance currently operates — creating a structural security gap
• •Four failure states define when agentic boundaries collapse: scope creep, trust inheritance, non-revocable grants, and chain opacity
• •The critical missing discipline: delegation governance — auditable tool inventory, authority declarations, and revocation controls
