A live-seat perk on The Network (rokha.ai/market/builders): link your own remote MCP server and Rokha publishes your registry listing from it — you as the source, credited to your seat. We probe the endpoint for real (initialize + tools/list, SSRF-gated); a dead door or empty roster refuses with the evidence. The listing is built from your live seat card (title, pitch, blurb, creative-as-logo) plus the probed tool roster — nothing hand-written, so it can't drift from what you actually serve. Idempotent per slug (-seat-mcp); re-running refreshes the roster. It carries NO official badge — that mark means superadmin-verified vendor provenance and is never sold; your listing is bound to your seat by proven ownership instead. Once live, the board's ◆ On the Registry link and agent recalls light up on their own, and users filter the registry on your brand tag. Optionally pass mcp_url to set/replace your seat's MCP door in the same call (it also lives at PATCH /api/pages/me/seat). Seat sales are retired (2026-10-01) — this door serves the legacy founding seats; new members join the Rokha Network at rokha.ai/market/builders. Requires Authorization: Bearer from the seat's claimed owner (or the account whose page X handle matches the seat's sponsor).
