Upstash Redis Key-Value Store

Interact with Upstash's Redis-compatible key-value store using the REST interface.

Script Location

bun run scripts/upstash-client.ts <command> [args...]

IMPORTANT : Always run with bun run, not directly.

Configuration

Environment Variables

The script uses these environment variables by default:

• UPSTASH_REDIS_REST_URL - The Upstash REST API URL
• UPSTASH_REDIS_REST_TOKEN - The Upstash REST API token

Overriding Credentials

If the user provides credentials from another source (conversation context, a file, etc.), use the --url and --token flags to override environment variables:

bun run scripts/upstash-client.ts --url "https://..." --token "AX..." GET mykey

Priority : Command-line flags > Environment variables

Confirmation Behaviour

Default: Ask for Confirmation

Before executing any destructive operation (write, modify, or delete), you MUST ask the user for confirmation. This includes:

Write operations:

• SET, SETNX, SETEX, PSETEX, MSET, MSETNX
• HSET, HSETNX
• LPUSH, RPUSH, LPUSHX, RPUSHX, LSET, LINSERT
• SADD
• ZADD

Modify operations:

• INCR, INCRBY, INCRBYFLOAT, DECR, DECRBY
• APPEND, SETRANGE
• HINCRBY, HINCRBYFLOAT
• LREM, LTRIM, LMOVE
• ZINCRBY

Delete operations:

• DEL, UNLINK
• HDEL
• LPOP, RPOP
• SREM, SPOP, SMOVE
• ZREM, ZREMRANGEBYRANK, ZREMRANGEBYSCORE, ZPOPMIN, ZPOPMAX
• FLUSHDB, FLUSHALL (extra caution)

TTL/Rename operations:

• EXPIRE, EXPIREAT, PEXPIRE, PEXPIREAT, PERSIST
• RENAME, RENAMENX

Example confirmation prompt:

"I'm about to HSET user:1 with fields {name: "John", email: "john@example.com"}. Proceed?"

YOLO Mode: Skip Confirmation

If the user indicates they do not want to be asked for confirmation, respect this for all subsequent operations. Indicators include:

• "YOLO mode"
• "Don't ask for confirmation"
• "You're free to make changes without asking"
• "Just do it"
• "No need to confirm"
• "Auto-approve" or "auto-confirm"
• Any similar phrasing indicating blanket approval

Once YOLO mode is activated, proceed with destructive operations without asking, but still inform the user what was done.

Example:

Set user:1 with {name: "John", email: "john@example.com"} - done.

Error Handling

If credentials are missing or invalid, the script will exit with an error message. Ensure the user has configured either:

1. Environment variables (UPSTASH_REDIS_REST_URL, UPSTASH_REDIS_REST_TOKEN)
2. Or provides credentials via --url and --token flags

When to Use This Skill

• User explicitly asks to store or retrieve data from Upstash/Redis
• Need to persist data across conversations or sessions
• Implementing caching for expensive operations
• Maintaining counters, rate limits, or statistics
• Storing user preferences or session data
• Building leaderboards or rankings (sorted sets)
• Managing queues or task lists (lists)
• Tagging or categorisation (sets)
• Storing structured objects (hashes)
• Any scenario requiring fast key-value storage
