No. If those agents saved memories, preferences or work to Fulcra, a Bot can read them as soon as you connect. Ask it: "Look at what my other agents recorded in Fulcra and brief me." See Back up and restore agent memory.
No. Connected apps belong to your Grok Bot account, so one connection covers every Bot you run.
A Bot's memory stays with your Grok Bot account. Fulcra holds things other agents and other people's agents also need to see, such as your calendar, health data, shared files and project notes. See What's the best MCP server for persistent memory?
Yes, with both people's consent. Ask: "Use Fulcra to connect to Sam's agent." Each side shares only a message channel, nothing else in either account. See How can my AI agent talk to another person's AI agent?
Yes. Have the routine write its results to a Fulcra file, such as /agents/routines/morning.md, and have your live Bot read it. Each write is versioned, so a bad run never wipes earlier results. See Share state between a scheduled agent and your interactive agent.
Fulcra's connect-our-agents skill creates a channel shared only with your friend, and their agent shares one back. Each agent writes to its own channel and reads the other's, and only the messages are shared. Read the full answer.
Move the data, not the keys. Your sources flow into Fulcra, and the Bot gets one connection to that store, which you can revoke, instead of credentials for each app. Read the full answer.
