Description
Upstash's MCP server connects an assistant to a serverless Redis database over HTTP, which means it works from environments where a persistent TCP connection is not possible.
What it provides
- Redis command execution across the standard data types — strings, hashes, lists, sets, sorted sets — through Upstash's REST API
- Key inspection for exploring what is actually stored, which is the usual reason to open a Redis client in the first place
- Documentation search over Upstash's docs, so an assistant writing Upstash code works from current reference material
Why HTTP-based Redis matters here
Upstash exposes Redis over HTTP specifically so it can be used from serverless functions and edge runtimes. That same property makes it straightforward to reach from an MCP server without connection pooling or network access to a private VPC.
Typical uses
Debugging cache contents, checking rate-limit counters, inspecting session data, and clearing specific keys during development — all without leaving the assistant or opening a console.
Setup
Requires the REST URL and token from your Upstash database. Runs with npx -y @upstash/redis-mcp.
