Dear Diary is an MCP server that provides semantic memory storage and retrieval capabilities using a Qdrant vector database. It enables AI coding agents and other MCP clients to persist information across sessions and retrieve it through semantic search.
The server exposes three tools:
- qdrant_store — Store information with optional metadata
- qdrant_find — Search for information using semantic similarity
- qdrant_deprecate — Mark entries as deprecated for graceful removal
