prune_memory

MCP tool from ArcRift by Eshaan-Nair

Surgically removes facts or chunks matching a description. Corrects outdated information without wiping an entire project.

How to use it

Project documentation lists prune_memory for the ArcRift MCP server. Add the server to your MCP client (Claude Desktop, Cursor, Windsurf and others), then check which tools your installed version makes available. Tool availability can depend on configuration and credentials. A server handshake does not verify this tool’s behavior. See the full listing for setup details.
