mcp.
8 capabilities over MCP. First atlas observation.
8 tools. 1 only reads. 4 only compute. 3 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 8 tools, and 5 have AI readings.
get_portfolio_returns is read as read-only.
Written by code from the AI readings on this page: it groups them and says nothing they do not.

AI reading, beta: AI adds items here; it never removes one.
No tool is read as one of the six effects. A zero is a count, not a clearance.

Each class compares an observation with the previous atlas observation. Runs of unchanged observations are grouped. Struck values are what the previous observation recorded; inserted values are what this one recorded.
