Dev setup instructions

pnpm i
cp apps/mcp-remote/.env.example apps/mcp-remote/.env
pnpm dev
  1. Set the VOYAGE_API_KEY for embeddings support

[!NOTE] Currently to prevent having a bunch of Timeout logs on vercel we shut down the SSE channel immediately. This means that we can't use server.log and we are not sending list-changed notifications. We can use elicitation and sampling since those are sent on the same stream of the POST request
