Dev ships free remote MCP server to check if ChatGPT and Claude recommend your product

Indie developer hookedupwithclaude turned Citemark — a tool that tracks whether ChatGPT and Claude recommend your product when buyers ask "what's the best X?" — into a remote MCP server usable from a Claude chat, with three free no-account tools:
- checkaivisibility: generates 5 buyer questions from a site's homepage, queries ChatGPT and Claude, reports mention rate, competitors, cited sites, and 3 fixes (1 min)
- getaipicks: which products AI recommends most across 10 software categories
- checkaicrawlers: which of 15 AI bots (GPTBot, ClaudeBot, etc.) a site's robots.txt allows
Hard-won integration lessons worth a day of anyone's time:
- Lazy auth only triggers on HTTP 401 with WWW-Authenticate: Bearer resourcemetadata=...; a 200 with isError just shows text and no Connect button
- Claude uses a client ID metadata document only if auth server metadata sets clientidmetadatadocumentsupported: true and "none" in tokenendpointauthmethodssupported, else it falls back to dynamic client registration
- Claude Code redirects to http://localhost:<random port>/callback — match loopback ignoring the port
- 240-second tool-call budget; stateless Streamable HTTP on Cloudflare Workers, no SSE
Data nugget: in feature flags, Flagsmith and Unleash appear in 92% of AI answers vs 33% for LaunchDarkly.
