Description

This MCP server exposes Deno KV operations (set, get, delete, getMany, list) as tools for MCP clients and agents. It supports both local and remote (Deno Deploy) KV instances via DENO_KV_PATH and optional DENO_KV_ACCESS_TOKEN, and can be run with Deno or via Node using xjsr/npx. The server is useful for adding persistent state, memory, or simple database capabilities to agent workflows and chat clients.
