mcp-deno-kv FAQ
How do I start the mcp-deno-kv server?
Run the server using the Deno command with the --unstable-kv flag and the jsr:@divy/mcp-deno-kv module as shown in the example.
What is required to use mcp-deno-kv with Claude Desktop?
You need to configure the MCP client to launch the mcp-deno-kv server with the specified command and arguments in the client’s mcpServers configuration.
Can mcp-deno-kv handle concurrent read and write operations?
Yes, it leverages Deno's KV storage which supports concurrent operations, making it suitable for multi-user or multi-agent environments.
Is the mcp-deno-kv server production-ready?
It uses Deno's unstable KV API, so it is best suited for development and experimental use until the API stabilizes.
What kind of data can be stored in mcp-deno-kv?
Any JSON-serializable data can be stored, enabling flexible structured context storage for LLMs.
Does mcp-deno-kv support secure data access?
Security depends on the deployment environment; the server itself does not enforce access control but can be secured via network policies.
Can mcp-deno-kv be used with other MCP clients besides Claude Desktop?
Yes, it can be integrated with any MCP client that supports external server configuration and communication.
How does mcp-deno-kv improve LLM workflows?
By providing persistent, fast key-value storage, it enables stateful interactions, caching, and coordination across LLM sessions.
