Phorvec

Persistent vector memory for AI agents. One file per agent, MCP-native, local-first.

What is Phorvec?

Phorvec is an embedded vector database designed for multi-agent AI systems. Each AI agent gets its own isolated .avdb database file with vector search, key-value storage, and a knowledge graph — all accessible through the Model Context Protocol (MCP).

Key Features

• One-file-per-agent architecture (.avdb files) — portable, isolated, no shared state
• MCP-native — works with Claude Code, Cursor, Windsurf, Cline, and any MCP client
• 150+ tools — context persistence, semantic search, team memory, conflict detection, skill library
• Local-first — all data stays on your machine, zero cloud dependency
• Hybrid search — vector similarity + BM25 keyword search with RRF fusion
• Knowledge graph — entity and relationship tracking across sessions
• Compression — PCA spine+delta encoding for storage efficiency

Quick Start

Install

pip install phorvec

Configure with Claude Code

Add to your Claude Code MCP settings:

{
  "mcpServers": {
    "phorvec": {
      "command": "phorvec",
      "args": []
    }
  }
}

Configure with Cursor / Windsurf

Add to your MCP configuration:

{
  "mcpServers": {
    "phorvec": {
      "command": "phorvec",
      "args": [],
      "transport": "stdio"
    }
  }
}

Use phorvec in your code (Python)

pip install phorvec

from phorvec import Memory
with Memory.open("./agent-memory", agent_id="assistant-1") as mem:
    mem.store("The user prefers metric units")
    for h in mem.recall("what units?", top_k=5):
        print(h.score, h.content)

pip install phorvec is the free (Community) library + the phorvec MCP CLI. Team/enterprise features (the phorvec.Team API) ship in the paid wheel from your account dashboard.

Architecture

Nexus (nexus.json)       — Central registry mapping agent IDs to file paths
    |
HandleManager            — LRU cache of open agent databases (default cap: 500)
    |
AgentDB (.avdb)          — Per-agent database with vector storage + KV store + graph

Configuration

Phorvec uses a TOML config file at ~/.phorvec/config.toml. The server runs with sensible defaults — no config file required.
