vector-memory AGENTS.md

Instructions for working on a vector-memory server, which stores documents so an assistant can find related information by meaning rather than exact words. The server uses Redis for storage and HuggingFace models to create searchable text representations.

In plain words
What is it for?
Use it when developing, testing, or publishing the server, including its document saving, natural-language recall, duplicate removal, and file chunking behavior.
Why use it?
It explains the project's architecture, data flow, testing approach, and development rules so changes can be made consistently.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

vector-memory AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Agent Guide - Vector Memory MCP Server

This document provides AI agents with comprehensive information about the codebase architecture, design decisions, and development guidelines.

Table of Contents

Project Overview

Purpose: MCP server that provides semantic memory capabilities for AI assistants using Redis vector store and HuggingFace embeddings.

Key Features:

  • Save files (PDF, TXT, MD) to vector memory
  • Recall information using natural language queries
  • Automatic duplicate removal when re-saving files
  • Smart chunking based on file type
  • Memory management tools

Tech Stack:

  • Language: Python 3.12+
  • Framework: FastMCP (MCP server framework)
  • Vector Store: Redis with RedisVectorStore
  • Embeddings: HuggingFace sentence-transformers
  • Build Tool: Hatchling
  • Package Manager: uv

Data Flow

  1. Save to Memory:

    File Path → Check Existence → Determine File Type →
    Get Optimal Chunk Size → Load Document →
    Remove Old Versions → Chunk Content →
    Generate Embeddings → Store in Redis
    
  2. Recall from Memory:

    Query → Generate Query Embedding →
    Similarity Search in Redis →
    Retrieve Top K Results → Format Output

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

vector-memory AGENTS.md is an instructions file published in the GitHub repository NeerajG03/vector-memory (0 stars, last pushed 10mo ago), licensed MIT. It adds 3,436 tokens to every session, about $0.0172 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
