mcp-data-buffer
Verified Safeby fastbs
Overview
Provides a universal data exchange buffer to offload large binary data from LLM context between MCP servers, passing tokens instead of raw data.
Installation
docker-compose up -d mcp-buffer-redis mcp-data-bufferEnvironment Variables
- PORT
- REDIS_URL
- DEFAULT_TTL
- NODE_ENV
Security Notes
Implements strong security measures including SHA256 hashed Bearer tokens, rate limiting per token, role-based scopes (read, write, admin), and a detailed audit log. Tokens are shown only once at creation and are impossible to brute force. Redis persistence ensures token survival across restarts. Automatic and manual cleanup mechanisms prevent data accumulation.
Similar Servers
mcp-memory-service
A Model Context Protocol (MCP) server providing persistent, semantic memory storage and retrieval capabilities for AI agents. It supports lightweight semantic reasoning (contradiction, causal inference), content chunking, multi-backend storage (SQLite-vec, Cloudflare, Hybrid), autonomous memory consolidation (decay, association, clustering, compression, forgetting), and real-time updates via SSE. It's designed for token-efficient interaction with LLMs.
