Overview
Momento MCP Server is a lightweight MCP server that exposes cache operations backed by Momento Cache. It implements the core MCP tools used by clients to interact with caches: get, set, list-caches, create-cache, and delete-cache. The get operation retrieves a value for a given key, with an optional cache name, and returns Hit with the value if found, Miss if not, or Error on failure. The set operation writes a value with an optional TTL, replacing any existing value and regardless of the previous data type. The list-caches operation returns a comma-separated list of all caches in the Momento account. The create-cache and delete-cache operations create and delete caches by name, returning Success or Error. The server is configured via environment variables, including MOMENTO_API_KEY (required), MOMENTO_CACHE_NAME (optional, defaults to mcp-momento), and DEFAULT_TTL_SECONDS (optional, defaults to 60). It can be run with MCP Inspector for testing and integration and can be installed from npm as @gomomento/mcp-momento. Typical usage involves building with npm run build, setting the API key, and invoking the inspector to connect to node dist/index.js.
