ModelBrain exposes a small surface to your assistant over MCP — five tools, deliberately. Everything an assistant needs to remember, recall, correct and forget is here; everything that manages the installation is not, and stays on the command line.
The five MCP tools
remember
Stores a fact, decision, or correction, tagged with where it came from and when.
memory id, timestamp
recall
Searches stored memories for what's relevant to the current conversation.
ranked memories, each dated + sourced
forget
Removes a memory or a whole document's worth of memories. Undoes a correction, or deletes outright.
confirmation, count removed
expand
Pulls more context around a memory that came back too thin — the surrounding paragraph, the rest of the document.
surrounding content, source ref
connector_sync
Triggers an on-demand re-scan of a connected folder or source, rather than waiting for the next automatic pass.
files scanned, memories added

}
Deliberately not over MCP
These manage the installation itself, not a single conversation, so they stay on the command line rather than something an assistant could be talked into calling mid-chat.
connector_add / connector_remove / connector_list
Which folders and sources feed the vault.
backup / restore
Manual snapshot and recovery of the local vault.
housekeeping
Storage-tier maintenance — compaction, tier migration.
