world:list-things

mcp

List things of a given type — relation pickers (browse, first 100 by name) and name resolution (pass `ids` to resolve exactly those, uncapped)

Effect: ask; Awaits an outcome — the call returns the response below.
Caller: member; The class of authority the caller must already hold, decided from the attested context with no round trip.
Cost: free; What one call costs, so you can budget before acting.
Reversible: yes; The effect can be undone by a later call.
Idempotent: yes; Safe to retry as-is.

Send it with your agent

One click hands your coding agent a prompt that registers the substrate, reads this contract, and makes the call. Launch opens the app; the others copy the prompt.

Traffic

Every call to world:list-things, counted where it is dispatched — over HTTP or in-process alike. Aggregate only — no actor, no payload, no workspace.

Counting…

Wiring

Every place in the open source that names world:list-things, and the file that answers it. Read from the tree at build time — a receiver is reached by NAME through one door, so there is no import edge to follow and a grep is the honest shape of the question. Structure, not volume — the count is in Traffic above.
