Yes. The Redis MCP Server is free and open source under the MIT license; you only need a reachable Redis instance, which can be local, self-hosted, or Redis Cloud.

Does it support remote/OAuth?

It runs locally over stdio via uvx (or a Docker image) and connects with a Redis URL or host/password env vars rather than OAuth. For managed Redis it supports EntraID/Azure authentication.

Redis MCP server

OfficialRedis520Config last verified Jun 1, 2026

Redis's official MCP server: read and write strings, hashes, lists, streams, JSON, and vector search.

The Redis MCP Server is Redis's official integration that gives an agent natural-language access to a Redis instance across every core data type. It exposes tools for strings, hashes (including binary vector fields), lists, sets, sorted sets, JSON documents, and streams with consumer groups, plus pub/sub publish and subscribe, key management (delete, expire, rename, type, and production-safe SCAN), and server introspection (DBSIZE, INFO, CLIENT LIST). It also ships a Redis Query Engine surface for creating HNSW vector indexes and running KNN and hybrid vector searches, making it useful as a semantic-memory or RAG backend, and a documentation search tool for answering Redis concept questions.

It is a Python server installed and run with uvx from the redis-mcp-server PyPI package over stdio, and a Docker image (mcp/redis) is also published. The connection target is supplied either with the --url command-line flag or through environment variables such as REDIS_HOST, REDIS_PORT, REDIS_PWD, and REDIS_DB, with TLS and Redis Cluster options available and EntraID/Azure authentication supported for managed deployments.

What you can do with it

Semantic memory for an agent

Create an HNSW vector index, store embeddings in hashes, and let the agent run KNN or hybrid searches to recall relevant context at query time.

Inspect and operate a cache

Ask the agent to SCAN for keys matching a pattern, check their types and TTLs, read stream entries, and report server stats from INFO without leaving the chat.
