Upstash Redis MCP

Official

Upstash Redis MCP

Add to Cursor

Lightweight MCP server for Redis with only two tools:

  • ๐Ÿงช redis_run_commands: run one or more Redis commands over HTTP/REST or TCP, as a pipeline or an atomic transaction.

  • ๐Ÿ“š redis_search_docs: search the Redis docs using Context7 public api.

One server can hold multiple named databases. Configuration is pure environment variables and CLI flags.

๐Ÿ”Œ Quickstart

Run this in your terminal. See the Claude Code MCP docs for more.

claude mcp add upstash-redis \
  -e UPSTASH_REDIS_REST_URL=https://<your-db>.upstash.io \
  -e UPSTASH_REDIS_REST_TOKEN=<your-rest-token> \
  -- npx -y @upstash/redis-mcp

Add to ~/.cursor/mcp.json (global) or .cursor/mcp.json (per-project), or go to Settings โ†’ MCP โ†’ Add new MCP server. See the Cursor MCP docs.

{
  "mcpServers": {
    "upstash-redis": {
      "command": "npx",
      "args": ["-y", "@upstash/redis-mcp"],
      "env": {
        "UPSTASH_REDIS_REST_URL": "https://<your-db>.upstash.io",
        "UPSTASH_REDIS_REST_TOKEN": "<your-rest-token>"
      }
    }
  }
}

Add to .vscode/mcp.json (per-project) or your user mcp settings. See the VS Code MCP docs.

{
  "servers": {
    "upstash-redis": {
      "command": "npx",
      "args": ["-y", "@upstash/redis-mcp"],
      "env": {
        "UPSTASH_REDIS_REST_URL": "https://<your-db>.upstash.io",
        "UPSTASH_REDIS_REST_TOKEN": "<your-rest-token>"
      }
    }
  }
}

Add to ~/.codex/config.toml (or a project-level .codex/config.toml). See the Codex MCP docs.

[mcp_servers.upstash-redis]
command = "npx"
args = ["-y", "@upstash/redis-mcp"]
env = { UPSTASH_REDIS_REST_URL = "https://<your-db>.upstash.io", UPSTASH_REDIS_REST_TOKEN = "<your-rest-token>" }

Add to opencode.json (project) or ~/.config/opencode/opencode.json (global). See the OpenCode MCP docs.

{
  "mcp": {
    "upstash-redis": {
      "type": "local",
      "command": ["npx", "-y", "@upstash/redis-mcp"],
      "environment": {
        "UPSTASH_REDIS_REST_URL": "https://<your-db>.upstash.io",
        "UPSTASH_REDIS_REST_TOKEN": "<your-rest-token>"
      }
    }
  }
}
TIP

Any MCP-compatible client works. If yours isn't listed, add astdio server that runs npx -y @upstash/redis-mcp with the two env vars above.

๐Ÿงฐ Tools

๐Ÿงช redis_run_commands

Run any Redis command: GET, SET, SCAN, ZADD, EVAL, the SEARCH.* family, and everything else. Each command is an array of args (numbers are accepted and coerced to strings). By default multiple commands run as a pipeline: each returns its own result/error, aligned to the input, and one failure doesn't abort the rest. Set transaction: true for an atomic MULTI/EXEC.

{
  "commands": [
    ["SET", "visits", 0],
    ["INCR", "visits"],
    ["GET", "visits"],
  ],
  "transaction": false, // optional: true => atomic MULTI/EXEC
  // "database": "prod"       // only when more than one database is configured
  // raw credential overrides (optional):
  // "rest_url", "rest_token" // HTTP
  // "connection_string"      // TCP, rediss://
}

The transport (HTTP vs TCP) is determined by how the target database is configured; the agent never picks it.

๐Ÿ“š redis_search_docs

Searches the Upstash Redis documentation live and returns the most relevant pages. Reach for it whenever you're unsure about a command or feature, especially Upstash-specific ones like the SEARCH.* full-text search family. It's powered by Context7's free tier, so no API key or extra setup is required.

{ "query": "SEARCH.AGGREGATE date histogram" }

โš™๏ธ Configuration

Everything is set through environment variables and CLI flags; there are no config files.

Single database

Transport

Environment

CLI

HTTP

UPSTASH_REDIS_REST_URL + UPSTASH_REDIS_REST_TOKEN

--rest-url <url> --rest-token <token>

TCP

UPSTASH_REDIS_TCP_URL (or REDIS_URL)

--url <rediss://โ€ฆ>

Multiple databases

Give each database a name. The name becomes a selectable database value in redis_run_commands.

Environment: insert a <NAME> segment:

UPSTASH_REDIS_PROD_REST_URL="https://prod-db.upstash.io"
UPSTASH_REDIS_PROD_REST_TOKEN="<prod-rest-token>"
UPSTASH_REDIS_CACHE_TCP_URL="rediss://default:<password>@cache-db.upstash.io:6379"

CLI: repeat --database to start each group:

npx -y @upstash/redis-mcp \
  --database prod  --rest-url https://prod-db.upstash.io --rest-token <prod-rest-token> \
  --database cache --url rediss://default:<password>@cache-db.upstash.io:6379
NOTE

Raw credentials per call. A redis_run_commands call may also pass rest_url + rest_token (HTTP) or connection_string (TCP) inline; these override the registry and work even with no configured database. They flow through the model's context, so prefer env/CLI for anything sensitive.

Flags & options

Flag

Env

Default

Purpose

--transport <stdio|http>

stdio

Server transport

--port <n>

3000

Port for the http transport

--readonly

UPSTASH_REDIS_READONLY

off

Best-effort: reject write commands on both transports. Server-side read-only REST tokens remain the robust option.

--disable-telemetry

UPSTASH_DISABLE_TELEMETRY

off

Stop sending Upstash-Telemetry-* headers on HTTP requests

--debug

off

Verbose logging to stderr + redis-mcp-debug.log

๐Ÿ“ก Telemetry

HTTP/REST requests carry Upstash-Telemetry-{Sdk,Platform,Runtime} headers. Disable with --disable-telemetry or UPSTASH_DISABLE_TELEMETRY=true.

๐Ÿƒ Run it locally

bun install
bun run build                 # emits dist/index.js
cp .env.example .env          # add UPSTASH_REDIS_REST_URL + UPSTASH_REDIS_REST_TOKEN

node dist/index.js                          # stdio (what clients spawn)
node dist/index.js --transport http --port 3000   # HTTP: endpoint /mcp, health /ping

The server auto-loads .env. To point a client at your local build, swap npx -y @upstash/redis-mcp in any Quickstart config for node /absolute/path/to/redis-mcp/dist/index.js.
