Make durable object storage more cost efficient for simple MCP servers

[remorses]

I run a free MCP plugin for Framer. I am using the agents npm package to expose this server.

The server is only used to forward the requests to another service and I basically only use this package to do authentication and networking with the MCP client

I spent a large amount of money on serving this MCP because the agents npm package seems to store a lot of data for each user session.

I also just discovered about this issue from the invoice I received via email because the billable usage histogram in the Cloudflare dashboard does not show this spendingw data from durable objects. So I thought I would be spending about $60 this month, instead I spent $676 just because of the use of the agents npm package

Is there a way to make the MPC durable object more efficient? Should I migrate away from the package?

McpAgent doesn't do much for storage by default, so I'm curious where the billing is happening. If you're not doing anything stateful, would the plain createMcpHandler be an option for you? https://developers.cloudflare.com/agents/api-reference/mcp-handler-api/

I investigated more, the issue was that my MCP was doing a lot of reconnects and creating a full new DO every time. Now I switched to using the MCP sdk package directly to quickly solve this
