11 capabilities over MCP. The inventory is incomplete. First atlas observation.
11 tools. 11 only read.◇
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 summary · beta
get_champion_build, get_champion_stats, get_leaderboard, and get_rank_cutoffs are each read as read-only.
get_event_standings, list_events, get_player_live_game, list_live_streamers, get_persona, get_player_profile, and search are each read as read-only.
The service has 11 capabilities, each with a reading, and each is listed without inputs.
Written by claude-haiku-5.5 from the tool names and the readings on this page, then checked against them. It can still be wrong; it never lowers or hides a fact.

Exact states and meaning
- ARDfailed
Exact state: unreachable · No document retrieved
The supported discovery location did not provide a usable response within the observation boundary.
An unreachable result does not prove the service is unavailable to every client or that it advertises no capabilities.

No endpoint was established from the evidence and scope that InterfaceDelta inspected.

Not observed / not fetched
- WebMCPabsent
Exact state: not detected · 0 declarative form tools · experimental
No named declarative WebMCP form tools were observed in the origin root HTML.
Script-registered tools and other pages are not observed, so this does not mean the site has no WebMCP tools.

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

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.
Declared and observed
11 tools declare hints; the AI readings agree with all 11 that have a reading.
A disagreement is not a finding about the service: either side can be wrong. How we compare declarations and readings.

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.
