dakera-mcp-0.2.1 is not a library.

Dakera MCP Server

MCP (Model Context Protocol) server that gives AI agents persistent memory through the Dakera vector database. Connect Claude Desktop, Cursor, Windsurf, or any MCP-compatible client to store, recall, and search memories across sessions.

Features

Agent Memory -- Store, recall, search, and consolidate semantic memories with importance scoring and tagging
Vector Operations -- Full vector CRUD with similarity search, batch queries, multi-vector search, aggregations, and hybrid ranking
Full-Text Search -- BM25-scored document search with hybrid vector+text mode
Knowledge Graph -- Build relationship graphs from memories, summarize, and deduplicate
Session Management -- Group related memories into sessions with metadata and summaries
Inference -- Upsert and query using natural language text with server-side embedding
Namespace Isolation -- Create and manage isolated vector collections with configurable dimensions and distance metrics

The server communicates over stdio using the MCP JSON-RPC protocol. Each tool call translates to one or more HTTP requests against the Dakera REST API. No local state is kept -- the Dakera API is the single source of truth.
