// Self-host serves MCP at the bare `/mcp` path (and bare OAuth discovery docs).// The console "Connect an agent" card, however, prints// `<origin>/<organizationId>/mcp` — a convention the multi-tenant cloud worker// routes (it strips the org segment at the edge, carrying the org in a header).// Self-host is single-tenant: the session already pins the one org, so the org// segment in the URL carries no routing meaning. Rather than special-case the// card per host, both self-host front-ends (the prod Bun server and the vite// dev middleware) strip a single leading segment so the card's URL reaches the// real route — mirroring cloud's edge rewrite, but accepting ANY segment (a// Better Auth org id is not the `org_…` shape cloud keys on) and setting no// header.//// Pure + Effect-free on purpose: the vite config imports it too. const PRM_PREFIX = "/.well-known/oauth-protected-resource"; /** * Given a request pathname, return the bare MCP pathname it should route to * when it carries a single leading org segment, or `null` when no rewrite * applies (already bare, not an MCP path, or an OAuth endpoint like * `/api/auth/mcp/authorize`). * *   /<seg>/mcp                                                -> /mcp *   /<seg>/mcp/toolkits/<toolkit>                             -> /mcp/toolkits/<toolkit> *   /.well-known/oauth-protected-resource/<seg>/mcp           -> /.well-known/oauth-protected-resource *   /.well-known/oauth-protected-resource/<seg>/mcp/toolkits/<toolkit> *                                                            -> /.well-known/oauth-protected-resource/mcp/toolkits/<toolkit> */export const stripMcpOrgSegment = (pathname: string): string | null => {  if (pathname.startsWith(`${PRM_PREFIX}/`)) {    const rest = pathname      .slice(PRM_PREFIX.length + 1)      .split("/")      .filter((segment) => segment.length > 0);    if (rest.length === 2 && rest[1] === "mcp") return PRM_PREFIX;    if (rest.length === 4 && rest[1] === "mcp" && rest[2] === "toolkits") {      return `${PRM_PREFIX}/mcp/toolkits/${rest[3]}`;    }    return null;  }  const segments = pathname.split("/").filter((segment) => segment.length > 0);  if (segments.length === 2 && segments[1] === "mcp") return "/mcp";  if (segments.length === 4 && segments[1] === "mcp" && segments[2] === "toolkits") {    return `/mcp/toolkits/${segments[3]}`;  }  return null;};
