In this work we present this epistemic resource logic ERL, based on Boolean BI, in which the epistemic modalities are parametrized on agents' local resources. The new modalities can be seen as generalizations of the usual epistemic modalities. The logic combines Boolean BI's resource semantics with epistemic agency. We discuss some examples about access control using resource tokens. Moreover We also study a labelled tableaux calculus and establish soundness and completeness w.r.t. the resource semantics.
