OneSignal for your agents.
Connect OneSignal once and every agent you run inside Even (Claude Code, Codex, OpenCode, Even Agents) can use it: 9 curated tools, discovered on demand, with your key stored on your machine and every call going direct to OneSignal.
What agents can do with OneSignal
Curated for agents: the calls that matter, with schemas and descriptions written for tool use, not an endpoint dump.
