Show HN: Prxhub – open registry so AI agents stop re-running the same research

Author here. Quick discussion question.

The hardest UX problem we've hit is getting fresh-session agents to discover and install an MCP server. We've layered a paste prompt, an HTTP Link header pointing at the MCP endpoint, and a doctor-style diagnostic. Works for the agents we test, but I keep wondering if there's a sharper pattern.

What have you seen work for bootstrapping new agents into MCP servers or unfamiliar tools? Curious about both protocol-level ideas and harness-level ones.
