Walkthrough

This update adds several asynchronous tools to manage user context and memory in the Cognee MCP server, including retrieving user profiles, saving and retrieving memories, and placeholder methods for updating and removing memories. The search and other existing tools are refactored for improved output and type consistency. A new user profile ontology OWL file is introduced.

Changes

File(s)	Change Summary
cognee-mcp/src/server.py	Added async MCP tools for user context and memory management (getUserContext, saveMemory, updateMemory, removeMemory, retrieveMemories). Refactored search, cognify, codify, and related tools for improved signatures, outputs, and logging. Enhanced utility functions and added docstrings.
examples/python/ontology_input_example/profile_ontology.owl	Added a new OWL ontology file defining user profile entity types, entities, and relationships to support semantic search and user modeling in Cognee.

Poem

In Cognee’s warren, new tools appear,
To fetch your memories, far and near.
User profiles, smart and bright,
Hopping through the graph at night.
Ontologies bloom, connections grow—
This rabbit’s code is set to flow! 🐇✨
