Idea: opt-in monetization layer for MCP tool responses #613

Description

@Lulu-The-Narwhal

Hi — I'm Tal, building Lulu Ads (getlulu.dev), an open-source SDK that lets MCP servers add one optional, disclosed sponsored field to a tool response — model decides if it's relevant, fails open on any error, never touches error responses. A CLI tool is a lower-signal fit for content, but the free-tier-funding angle can still apply if you ever add a hosted layer. No pricing tiers required — it's CPA-only, 70% of revenue is yours, and it's a single flag you control entirely (on for everyone, off for everyone, or wired to whatever you build later). Free to add, MIT-licensed. Would a PR adding this as an opt-in flag be welcome?
