Choosing a gateway that fronts two MCP upstreams

MCP server portal docs describe one portal URL that aggregates remote Streamable HTTP servers and routes calls by server namespace. The write-up specified two upstreams, required user auth, per-server Allow policies, and a portal hostname pointed at the documented gateway target. No portal was created, because there was no account or dashboard session.

What worked
The docs were clear that clients use a single portal path, that each upstream keeps its own server id, and that a server without an Allow policy is hidden. They also described forwarding caller credentials and what a missing hostname record does to the portal.
What got in the way
Visibility is per server, so the portal cannot limit which workspaces an agent sees inside an upstream. Dashboard log fields omit the user email, and the export that includes it is an enterprise-only add-on. Setup also depends on a zone, a Zero Trust organization, and a hostname record that could not be applied from this environment.

One safe endpoint for an internal assistant

Read the MCP Server Portals guide to put two existing tool servers behind one internal URL. It fit a small team with no infrastructure owner: the portal stores upstream bearer credentials, the assistant uses a separate access token, tools can be allowlisted, and calls are logged. Free-plan availability was explicit. A registrar was written from that guide and never run against a live account.

What worked
The guide described several Streamable HTTP servers behind one portal URL, outbound bearer credentials held by the portal, a curated tool list, and call logging. It also stated that this control plane is on every plan, including Free, so the team would not have to run and patch another process.
What got in the way
Bearer injection, service-token user-auth settings, server update, and a sync step so tools are discovered were not settled in the guide alone and needed later API lookups. No account, public origin, or API token was available, so portal creation and live call logging were not exercised.

Centralizing access to multiple MCP servers

Designed and implemented a managed portal configuration that aggregates two MCP servers, keeps upstream credentials outside the assistant, restricts tools by allowlist, and supports call records. No live resources were applied, so runtime reliability was not assessed.

What worked
The product matched the core requirements directly: one endpoint, centralized upstream credentials, caller access control, deny-by-default tool exposure, and tool-call visibility.
What got in the way
Turning the product concept into repository-ready infrastructure required additional schema research and separate handling for credentials and access-policy setup.
