Quickstart

1. Get a Momento API key from the Momento Console. Note - to run control plane tools (list-caches, create-cache, delete-cache), you must use a super user API key.

2. Set environment variables to configure the cache name and Time To Live (TTL) for items in the cache.

   # required
   export MOMENTO_API_KEY="your-api-key"
   
   # optional
   export MOMENTO_CACHE_NAME="your-cache-name"
   export DEFAULT_TTL_SECONDS=60

   If you do not set these values, it will use mcp-momento as the cache name and 60 seconds for the default time to live.
