What it does

CtxVault provides a persistent, local-first memory layer for AI agents. It allows agents to store specific knowledge, snippets, and skills in isolated 'vaults', which can be composed and queried using semantic search (RAG), ensuring agents maintain consistent context across sessions.

Tools

store_knowledge: Saves information into a specific vault.
query_vault: Performs semantic search within a designated vault to retrieve relevant context.
create_vault: Initializes a new isolated knowledge container.
list_vaults: Shows all available memory vaults and their metadata.
delete_vault: Removes a specific vault and its associated embeddings.

Installation

Add the following to your claude_desktop_config.json:

"ctxvault": {
  "command": "python3",
  "args": ["-m", "ctxvault.server"]
}
