MCP tool logging system updated to clarify absent digests

By PulseAugur Editorial · [1 sources] ·

The HISTOR system, which logs MCP tool definitions, has been updated to version 1.2 to better record the revision of rules used when a tool-set digest is absent. Previously, old records could be preserved without indicating which rule revision produced the result, leading to uncertainty. The update clarifies that a missing digest is not an indicator of server safety but rather a result of the measurement rules. New labels explicitly state the profile revision, while old records retain their original uncertainty. AI
