55 capabilities over MCP. First atlas observation.

Observed 6 Nov 2026, 21:04 UTC · passive: no tools called, no credentials sent · sha256:4bf954…f46c

55 capabilities, 28 of them tools. 2 only read. 1 changes records. 1 sends messages. 1 reading is disputed. 23 have no reading.

AI reading, beta. side-effects v1 on claude-haiku-5.5, calibrated on MCP (golden-3). Only readings above a measured precision count. Counts are tools, not calls: no tool was called.

AI readings summary · beta

The service lists 28 tools, and 4 have AI readings.

nucleus_relay is read as sending messages to people.

nucleus_lane_feedback is read as creating records.

nucleus_plan_list and nucleus_relay_subscribe are read as read-only.

Written by code from the AI readings on this page: it groups them and says nothing they do not.

The atlas shows each capability by its plain identifier, inputs and declared sign-in. Publisher descriptions, paths, links and source evidence are not published here.

The comparison with the previous observation is shown only to the account that recorded it.

Identity and snapshot

Target key: sha256:bc1c5fdb7ab72506f7e144b50974838734a4627f0cb7c696d89a2ef319d45bf4

Snapshot generated: 11 Nov 2026, 22:36 UTC

The entry is one exact observed target, not a real-world service identity, and implies no ownership. Endpoint paths are not published; the locator hash lets an operator confirm their own URL.
