#MCP Tool Reference

Memory Engine exposes 15 tools to AI agents over the Model Context Protocol. Once an agent is connected (see MCP Integration), it can inspect its context, store, search, and organize memories with the tools below.

If you are an agent using these tools, start with MCP Agent Instructions for when to search, what to store, and how access control affects visible and writable trees.

#Context

Tool	Purpose
me_memory_context	Show current identity, active space, and effective access

#Storing and editing

Tool	Purpose
me_memory_create	Store a new memory
me_memory_update	Modify an existing memory
me_memory_delete	Delete a memory by ID
me_memory_delete_by_path	Delete a named memory by its tree/name path
me_memory_delete_tree	Delete every memory under a tree prefix

#Retrieving and searching

Tool	Purpose
me_memory_search	Search by meaning, keywords, or filters
me_memory_get	Retrieve a memory by ID
me_memory_get_by_path	Retrieve a named memory by its tree/name path
me_memory_count	Count memories matching a tree filter
me_memory_tree	View the tree structure with counts

#Organizing and moving

Tool	Purpose
me_memory_copy	Copy memories between tree paths
me_memory_mv	Move memories between tree paths

#Bulk import and export

Tool	Purpose
me_memory_import	Bulk import from a file or inline content
me_memory_export	Bulk export with filters
