<hr/>

MemMCP is a hyper-optimized Memory Server natively implementing the Model Context Protocol (MCP). It bridges the gap between lexical keyword search and semantic vector embeddings, delivering 100% deterministic, deduplicated memory recall for autonomous AI Agent Swarms.

🤔 Why MemMCP?

When dozens of autonomous agents operate in parallel, standard vector databases suffer from race conditions, data duplication, and context hallucination. MemMCP solves this by merging SQLite Write-Ahead Logging (WAL) for ACID-compliant state management with FAISS Hybrid Reciprocal Rank Fusion (RRF) for unparalleled semantic retrieval.

✨ Core Features

Feature Description Architecture
Byzantine Fault Tolerance Strict isolation of execution states using Bloom-Filter Idempotency tracking. Never stores the same memory twice. SQLite WAL
Data Integrity Dual-ledger Distributed Consensus architecture powered by Merkle-Root signatures. msvcrt RWLocks
O(N) Vector Batching Bounds FAISS Semantic search with hybrid RRF logic executing strictly within <50ms latency bounds. FAISS + FTS5
Zero-Trust Execution Hardened against indirect prompt injection with explicit XML RAG bounding. MCP stdio

🚀 Quick Start

MemMCP is designed to be booted instantly by any MCP-compliant LLM or Agent Framework via standard IO streams (stdio).

# 1. Clone the repository
git clone https://github.com/axton/project_2_mcp_memory.git
cd project_2_mcp_memory

# 2. Build the exact dependency graph using uv
make build

# 3. Verify the rigorous mathematical test suite
make test

# 4. Boot the MCP server directly
make run

🛠 MCP Tool Reference

MemMCP automatically exposes the following functions to any connected agent:

  • store_memory: Store a single memory. Generates unique keys and updates FAISS indices.
  • store_memories_batch: Store multiple memories atomically in a single massive transaction, rebuilding the index only once.
  • recall_memories: Retrieve relevant memories using Reciprocal Rank Fusion (blending Semantic FAISS similarity + SQLite FTS5 keyword search).
