Upstash Redis MCP

</div>

Lightweight MCP server for Redis with only two tools:

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

🔌 Quickstart

<details> <summary><b>Claude Code</b></summary>

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

</details>

<details> <summary><b>Cursor</b></summary>

Add to ~/.cursor/mcp.json (global) or .cursor/mcp.json (per-project), or go to Settings → MCP → 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>"
      }
    }
  }
}

</details>

<details> <summary><b>VS Code</b></summary>

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>"
      }
    }
  }
}

</details>

<details> <summary><b>Codex</b></summary>

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>" }

</details>

<details> <summary><b>OpenCode</b></summary>

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>"
      }
    }
  }
}

</details>

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

🧰 Tools

🧪 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.

📚 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" }

⚙️ 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://…>

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

📡 Telemetry

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

🏃 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.
