Fulcra: a user-owned context store shared across Claude, ChatGPT and Grok
Fulcra moves context out of individual apps into storage the user owns, letting multiple agents share the same health, calendar and location data over MCP.
your agents don't have a memory problem. they have an ownership problem. every agent you add starts as a stranger, because your context lives inside its app Fulcra moves it out: one context store that belongs to you, not your apps > every agent, same context: Claude, ChatGPT and Grok over MCP, Hermes and OpenClaw over the CLI > teach once: health, calendar, location in one store, every new agent skips onboarding > your keys: choose what's shared, keep access scoped, revoke any time > agents that work together: one team on one project, messages to someone else's agent, groups across accounts B
