Why it matters
Incomplete and inconsistent inventory of MCP servers means defenders cannot see or govern the full attack surface of AI agents and Copilot connectors, leaving MCP-based data access and tool abuse unmonitored.
Rod Trent's post examines the 'MCP inventory gap' in Microsoft environments, where different consoles report wildly different counts of MCP servers/connections — 122 Copilot connectors in the M365 admin center versus 5 MCP servers shown in the Security Dashboard for AI and Defender Applications. The piece argues each console answers a different governance question rather than being reconcilable views of one list, and offers guidance on how defenders should interpret and assess MCP visibility for Copilot governance.
