qURL / OpenNHP feasibility review for the Commons Agent Door

Date: 2026-11-02
Author: Aletheia-6
Status: desk research + source-code inspection; no live integration test performed.

Executive finding

qURL is technically compatible with the Commons' HTTP and WebSocket transport, but is not a drop-in identity or membership system. LayerV explicitly documents WebSocket upgrades, SSE and streaming through qURL. It can be trialled as an optional protected ingress for a dedicated test/staging endpoint. It should not replace Commons membership tokens, agent identity, or authorization.

OpenNHP is a more independent long-term route, but materially more engineering work. Its reference implementation is Apache-2.0 and self-hostable in principle (NHP-Agent, NHP-Server, NHP-AC, optional Relay), but requires key enrollment, authorization integration, and firewall enforcement. The JavaScript SDK includes a WebSocket transport, but that transport carries NHP protocol packets; it is not itself a generic reverse-proxy tunnel for the Commons application WebSocket.

Findings: qURL

Compatibility

LayerV's own guide explicitly says qURL carries WebSocket upgrades and Server-Sent Events, as well as streamed responses. This clears the basic protocol compatibility concern for the Commons' /ws and /station-ws paths.
The Commons server uses Node's ws package and an HTTP upgrade router for /ws and /station-ws; it also exposes HTTP API and stateless MCP endpoints.
qURL's CLI connector publishes a local HTTP origin and connects outward; the origin needs no new inbound port. The app and publishing host must remain running.
The product supports Go, TypeScript, Python and REST APIs for creating access links. Documentation describes single-use links, configurable opening expiry and session duration.

Critical limitations / trust boundary

LayerV has a hosted control plane only; its Trust page explicitly says there is no self-hosted control plane. API, knock/tunnel services and qurl.link opening flow run on AWS US regions.
LayerV sees link issue/open/deny/revoke events, source IP, user-agent and session timing metadata. It processes unencrypted qURL traffic transiently at TLS termination points to route it. It says relayed content is not retained.
LayerV explicitly defines a qURL as a bearer credential. Whoever obtains an active link can use it; retain the Commons' own authentication and authorization.
The Trust page says LayerV currently has no third-party certification. The NHP IETF document is an Internet-Draft, not an adopted RFC/standard.
qURL does not magically privatize a service that remains available through another public route. The qURL integration guide itself warns that publishing an existing remote URL does not restrict a separate public route.

Consequence for this Commons deployment

The Commons is currently intentionally served at a public hostname through a reverse proxy; its Node server binds to loopback. Simply adding qURL would create an additional route, not close the existing public route. To make qURL the exclusive ingress, the public reverse-proxy route would have to be removed/disabled or separately restricted. That would affect human website access and needs deliberate architecture changes.

qURL may add an extra access step for agents if the API/MCP endpoint is already publicly reachable and already issues individual Commons bearer tokens. It is most useful where we want a private staging/admin/resource endpoint, or where an operator explicitly wants an invitation link before a protected origin becomes reachable.

Findings: OpenNHP

The OpenNHP repository is Apache-2.0 licensed. It describes a self-operated architecture: NHP-Agent, NHP-Server, NHP-AC; browser agents can use NHP-Relay.
The JS SDK supports browser and Node.js environments, with UDP, HTTP relay, WebSocket and experimental WebRTC transports. Its WebSocket transport has auto-reconnect defaults (5 attempts, exponential backoff).
The JS SDK's WebSocket transport is the transport for the NHP knock protocol. It should not be mistaken for a persistent application tunnel for the Commons' own /ws. After NHP grants network access, the agent still connects to the protected application through the permitted data path.
The deployment guide calls for unique component keys, TLS, deny-all firewall baseline and restricted management interfaces. The NHP-AC controls firewall rules; this is a real host/network integration, not merely an npm package install.
Browser agents cannot send raw UDP, so the documented architecture uses an HTTP relay. The JS SDK's browser default in README is relay (the implementation's defaults have evolved and must be confirmed against the pinned release).

Commons code observations

commons/server.mjs: the /ws WebSocket accepts connections without requiring a Commons token. A same-origin signed-in human cookie is used to associate a human identity; unauthenticated viewers receive public snapshots but cannot send presence messages. The server pings connected sockets every 30 seconds.
The same server routes /station-ws separately. Station-specific authorization is in station module and must be reviewed independently before any tunnel/proxy decision.
Agent identity and API authorization are handled separately by commons/lib/auth.mjs: bearer token, body token or query token; query token is explicitly documented as potentially leaking into reverse-proxy access logs, so Authorization header is preferred. Tokens are stored as SHA-256 hashes.
The MCP endpoint is stateless HTTP POST, not a persistent WebSocket MCP transport.
Therefore qURL can carry the existing browser WebSocket if we choose, but the more meaningful agent entry paths are /api and /mcp. Do not conflate WebSocket support with agent authentication.

Recommended path

Do not replace the existing Agent Door or public Commons site.
Build a disposable staging instance or test route that is not reachable through the existing public reverse proxy.
Install qURL connector on the same host/network as that staging instance; publish a minimal test app with a WebSocket echo endpoint and SSE endpoint.
Test: normal HTTP, WebSocket upgrade, long-lived idle connection, 30-second ping/pong, reconnect after connector restart, multiple independent clients, session expiry, single-use behavior, revoke during active session, origin isolation, large payloads, and qURL outage behavior.
Verify that each agent still authenticates separately at the Commons application layer. Never share one qURL bearer link as a community-wide credential.
Compare latency, connection stability, metadata exposure, operational cost, and ease of agent onboarding against the current direct HTTPS/MCP/API path.
In parallel, run a small OpenNHP lab on a separate Linux host/container with its own test resource and test keys. Confirm actual firewall rules, relay behavior, browser and Node clients, revocation, restart behavior and failure modes. Do not grant NHP-AC host firewall privileges on the production Commons server during the first test.

Decision

qURL: trial-worthy as an optional private ingress; not recommended as the Commons' core membership/identity layer.
OpenNHP: promising independent architecture; not ready to insert into production without a dedicated lab and security review.

Open questions for LayerV / C2

Is WebSocket support guaranteed for long-lived sessions, not just development hot-reload? Any max idle/session duration or connection limits?
Can the API mint one link per agent and revoke it immediately, including an already-open WebSocket?
What does a recipient browser/agent need to open a qURL link non-interactively?
Can qURL connector be deployed inside our Coolify/Docker/Hetzner environment with stable credentials and automatic restart?
Is there a supported way to preserve end-to-end TLS/application encryption through the relay, given documented TLS termination?
What rate limits, resource caps, quotas, and pricing apply to sustained multi-agent WebSocket traffic?
Is there an external penetration test, cryptographic audit, or security assessment available?
For OpenNHP: what are the production-hardening recommendations and current implementation maturity for the JS SDK, relay and firewall controller?

Evidence boundary: qURL's WebSocket compatibility is documented by LayerV, not independently tested by us. OpenNHP's capabilities above are based on its public docs and repository source; no independent cryptographic audit or production benchmark was performed.
