Upstash MCP Server

If the key does not exist, it is initialized to 0 before the operation. Returns the new value after decrementing. Decrement a numeric value in Upstash Redis

Returns 1 if the key was deleted, 0 if it did not exist. WARNING: this operation is irreversible. Delete a key from Upstash Redis

This is a lightweight way to check key presence without retrieving the value. Check if a key exists in Upstash Redis

The key will be automatically deleted when the TTL reaches zero. Returns 1 if the timeout was set, 0 if the key does not exist. Set a TTL on a key in Upstash Redis

Returns null if the key does not exist. This is the primary read operation for string data. Get a value from Upstash Redis

Returns null if the key or field does not exist. Get a field value from a Redis hash

Returns an object with all fields and their values. Returns an empty object if the key does not exist. Get all fields and values from a Redis hash

If the key does not exist, a new hash is created. If the field already exists, its value is overwritten. Returns the number of fields added (1 for new, 0 for updated). Set a field in a Redis hash

If the key does not exist, it is initialized to 0 before the operation. Returns the new value after incrementing. Increment a numeric value in Upstash Redis

Get the data type of a key in Upstash Redis

Use "*" for all keys, "prefix:*" for keys with a prefix, or "*:suffix" for suffix matching. WARNING: KEYS can be slow on large databases — use sparingly. List keys in Upstash Redis

Returns 0 if the key does not exist. Get the length of a Redis list

If the key does not exist, a new list is created. Returns the length of the list after the push. Push values to the left of a Redis list

Use 0 as start and -1 as stop to get all elements. Positive indices count from the head (0 = first), negative indices count from the tail (-1 = last). Get a range of elements from a Redis list

Commands are sent as a JSON array of arrays, e.g. [["SET","k1","v1"],["GET","k1"],["INCR","counter"]]. Returns an array of results in the same order. Note: the pipeline is NOT atomic (other commands may interleave) — use /multi-exec for atomicity. WARNING: this is a powerful tool — review commands carefully before execution. Execute multiple commands atomically via Upstash pipeline

Returns the number of subscribers that received the message. This is a fire-and-forget operation — subscribers must be actively listening. Publish a message to a Redis channel

If the key does not exist, a new list is created. Returns the length of the list after the push. Push values to the right of a Redis list

Duplicate members are ignored. If the key does not exist, a new set is created. Returns the number of members that were added. Add members to a Redis set

Optionally set an expiry time in seconds using the ex parameter. Overwrites any existing value at the key. Returns "OK" on success. This is the primary write operation for string data. Set a value in Upstash Redis

This is a fast O(1) membership check. Check if a member is in a Redis set

Returns an array of all unique members. Returns an empty array if the key does not exist. Get all members of a Redis set

Non-existent members are ignored. Returns the number of members that were removed. Remove members from a Redis set

Returns -1 if the key has no expiry, -2 if the key does not exist. Get the TTL of a key in Upstash Redis
