# tool si.read.catalogue

a tenant or a brand: every source and connector with its kinds of reading and action, its state, the identity it needs, its cost, its rights, its coverage and its health.

[figure: Over MCP, si.read.catalogue takes CatalogueInput and returns a card whose body is [SourceCatalogueEntry].]

every source and connector with its kinds of reading and action, its state, the identity it needs, its cost, its rights, its coverage and its health. The call needs the read grant at the tenant rung.
