MCP recommends selective data capture for audit logs to prevent liability

Audit logs, initially intended for security, can become liabilities if they indiscriminately copy sensitive database results. To mitigate this, an MCP audit record should focus on preserving essential operational context rather than every returned value. This includes details like identity, tool versions, data boundaries, and truncation status. A recommended approach is to classify evidence before retention, keeping recent metadata searchable, moving investigation evidence to a warm tier, and archiving only what is strictly required by obligations. Raw payload capture should be exceptional, restricted, encrypted, and short-lived, with rigorous testing of both restoration and deletion capabilities. AI
