What this does

rig mcp serve --http --cloud-grants <url> takes its grants from OpenRig Cloud instead of the local token file. It's meant for a Core instance whose callers are Cloud customers.

On every request:

• The lookup: the server POSTs {"instance": "<this daemon's self id>"} to Cloud's grant endpoint. The caller's raw customer key goes as the Bearer, under contract openrig.cloud.grant/v1.
  • Cloud stores only the key's hash, so the hash is never sent: accepting it would make the stored verifier a credential.
  • Nothing is cached, so a disconnect applies from the next request.
• The instance id: it's the self id of the daemon this server acts on, read from that daemon's /healthz, never from a caller.
• Refusals: every answer but active is refused, and so are a timeout, an unknown schema, a non-JSON body and an instance or rig mismatch.
  • unknown, revoked, expired and wrong_instance reply 401.
  • Cloud being unavailable replies 503 grant_authority_unavailable.
  • There's no fallback to the token file or to the env's seat, and with --cloud-grants the token file is never read.
• Early refusals, before any call to Cloud: a credential that isn't a customer key, and a daemon with no self id.
• The seat: Cloud names the caller's seat, which must already exist on this daemon. It's checked through whoami and never created; otherwise the reply is 503 seat_unavailable.

A customer grant is narrower than a work grant (customerScope in mcp-server.ts):

• Tools: only those its objects name: rig_queue_create, rig_queue_show, rig_queue_list and rig_artifact_read. A pair Core doesn't recognize offers nothing.
• show and list: only the items it sent, and the team's questions to it. Never team-internal items, another caller's items, another rig's or another host's. Its lists are limited to its own items, so the daemon's limit counts those.
• Successors: a handed-on item's successor is named only when it came back to the caller.
• Artifacts: only of its own items, under the root names the grant lists, and never by root and path alone.
• create: goes only to seats of its rigs on this instance, never to a person or another host's seat.

Unchanged: self-hosted grants from the token file, and their scope. The token-file path's replies are byte-identical.

Protected deployments: --cloud-grant-header-file <path> reads one Name: value line from a secret file and sends it with each grant request, and only to that exact URL. Redirects are refused, and the file can't set Authorization, Content-Type, Content-Length or Host.

Commits

1. 9f9b1384: the grant source and the customer scope.

2. 78f426ba: a customer can't hand a task to a caller seat: neither itself nor any seat shaped like Cloud's caller seats, cus-<id>-caller@<rig>. Version 1 of the contract marks no seat as a caller, so this shape is the only guard if two customers ever shared a rig. This commit waits on a product decision, so 0f93cfed reverts it for this merge. It comes back by reverting 0f93cfed. Without it, a customer's task can go to any seat of its rigs on this instance.

3. e5321068, round 1:

   • A handed-on item's out-of-scope owner is no longer named. That covers handedOffTo, the closure target on the item, its closing transition and the handoff transition, the handoff's note and the daemon's custody advisory.
   • A successor is named only when the whole row passes the customer's predicate. A cross-host successor stays hidden, and otherSuccessors is filtered.
   • An id-reuse conflict on an item the customer can't see no longer names that item's parties.
   • Other callers' responses are unchanged.

4. 692d6b2b, round 2: one projection on every row a customer receives: show's item and transitions, list rows, and create's return, idempotent retries included.

   • The row's facts stay: state and closure reason.
   • Parties the customer may not see go, whatever put them there: a handoff, a park, an escalation or a supersede.
     • In the closure target, that closure's note becomes "handed on", "escalated", "superseded" or "parked" (out of scope).
     • Also blockedOn, a transition's wake, the custody advisory, the waiting view's blocker and backstop owners, and the pickup receipt's evidence.
     • Item ids and out-of-scope seats inside transition notes.
   • Kept: a denial's or a cancel's own text stays readable unless it starts with an item id or contains a seat-shaped @ value (see the named limitations).

What the caller-seat checks rest on: the read rule that ignores items from caller-shaped seats (and the caller-seat create refusal, once it re-lands) is only as strong as OpenRig Cloud's provisioning contract: one customer per environment rig, with caller seats named cus-<id>-caller@<rig>. It is not general tenant isolation. Matching the instance is a configuration binding, not cryptographic instance authentication.

Tests

packages/cli/test/mcp-http-cloud-daemon.test.ts has 10 cases. They use the daemon's real routes, the real HTTP listener, the MCP SDK's own HTTP client, and a fake grant authority that speaks v1.

• The request Cloud sees: the raw key, the self id as the body, and the header from the file, on every request. The token file isn't read: a token-file credential, even an owner's, is refused before any call.
• Each refusal:
  • every non-active status;
  • another schema;
  • a non-JSON body;
  • a mismatched instance or rig;
  • an expired grant;
  • a missing seat;
  • an unbound self id;
  • Cloud down.
    Nothing is written in any of these.
• The customer scope:
  • creates out of scope;
  • team-internal items, another caller's items and another rig's items hidden from show and list;
  • a successor hidden or named;
  • artifacts of its own items only, never by path.
• The header file's format and its refused names.

Fail-before: widening the create destination, the artifact predicate or the path rule each fails the scope test, and so does removing commit 2's refusal.

Run locally: the four MCP test files pass, 77 tests (--maxWorkers=2). Round 1's two new cases fail before e5321068, and round 2's four (retry, park, escalation, supersede) fail before 692d6b2b; all pass after. tsc --noEmit for the CLI, the docs guard and the packing test also pass.

Cost

• Source: +392/-49 (net +343), rounds 1 and 2 included. Tests: +374, about 1 test line per source line. Docs: one row in the CLI reference.
• New codes: 503 grant_authority_unavailable and 503 seat_unavailable. They're reached only with --cloud-grants.
• New refusals: none on an existing path. The customer scope applies only to the new grant type, and commit 2's refusal is held as above.

Named limitations (after the last review round)

• A hidden predecessor's id: when the team hands a customer's task to an internal seat and that seat hands it back, the returned item's handedOffFrom and chainOfRecord carry the internal item's id. They never carry its owner or body, and an id-reuse conflict on it says only "taken".
• Who acted: a visible transition's actorSession names whoever acted on the customer's own item, normally a team seat. It can also be an orchestrator, a sweep or a person who acted.
• Free text the team writes for the customer stays as written: the task's body and its answer (resolution). Masking in transition notes is by shape: item ids and member@rig seats.
• A denial's or a cancel's target text is hidden only if it starts with an item id or contains an @. An item id written later in that prose ("… see qitem-…") stays readable. That reveals an id only, never the item's owner or body. Transition notes, by contrast, are masked wherever an id appears.
• Without the caller-seat create refusal (reverted above until the product decision), a customer can address a task to any seat of its rigs, another customer's caller seat included, if two customers ever shared a rig. Cloud provisions one customer per environment rig.
• Self-hosted work grants keep their existing responses. The same projection isn't applied to them here.

Not in this PR

• The daemon recording the validated principal on the rows a caller writes. That's a separate PR.
• Serving under a path other than /mcp. A proxy rewrites it.

Summary by CodeRabbit

• New Features
  • Added optional OpenRig Cloud grant authentication for HTTP connections, configured with a grants URL and an optional request header from a secret file.
  • Cloud-granted access is limited to permitted objects and actions. Queue items, artifacts, and related details are scoped to the caller’s access.
  • Startup messages distinguish Cloud grant, bearer-token, and unauthenticated loopback connections.
• Bug Fixes
  • Invalid option combinations and invalid or unavailable grant checks are rejected without falling back to token-file authentication.
• Documentation
  • Updated the command reference with the new options.

Walkthrough

rig mcp serve adds Cloud grant authentication for HTTP service. The server validates grants against the daemon instance and limits customer access to granted tools and resources. The CLI reference and integration tests cover the new options and access behavior.

Changes: Cloud-granted MCP access

Layer / File(s)	Summary
Configure Cloud grant options packages/cli/src/commands/mcp.ts, docs/as-built/cli-reference.md	The CLI accepts a Cloud grant URL and optional header file for HTTP service. It validates option combinations, passes the settings to the server, and reports the configured authentication mode. The reference documents both options.
Validate Cloud grants and authenticate requests packages/cli/src/mcp-http.ts, packages/cli/test/mcp-http-cloud-daemon.test.ts	The server checks each Cloud grant against the daemon instance and verifies the granted seat. It refuses invalid or unavailable grants and retains token-file authentication as an alternative. Tests cover authentication responses and header-file validation.
Enforce customer tool and resource scope packages/cli/src/mcp-server.ts, packages/cli/test/mcp-http-cloud-daemon.test.ts	Customer grants determine available tools and restrict queue, successor, list, path, and artifact access. Queue responses redact out-of-scope handoff details. Tests cover scoped access and ID-reuse conflicts.

L102: ## Goals
L103: 
L104: The goal is to unify fetching across the web platform and provide consistent handling of everything that involves, including:
L105: 
L106:   * URL schemes
L107:   * Redirects
L108:   * Cross-origin semantics
L109:   * CSP 【93†[CSP]】
L110:   * Fetch Metadata 【94†[FETCH-METADATA]】
L111:   * Service workers 【95†[SW]】
L112:   * Mixed Content 【96†[MIX]】
L113:   * Upgrade Insecure Requests 【97†[UPGRADE-INSECURE-REQUESTS]】
L114:   * ``Referer`` 【98†[REFERRER]】
L115: To do so it also supersedes the HTTP `【99†`Origin`】` header semantics originally defined in The Web Origin Concept. 【100†[ORIGIN]】
L116: ## 1. Preface
L117: 
L118: At a high level, fetching a resource is a fairly simple operation. A request goes in, a response comes out. The details of that operation are however quite involved and used to not be written down carefully and differ from one API to the next.

# Fetch

&gt; Stability: 2 - Stable

undici implements the WHATWG Fetch Standard, providing `fetch()` together with the `Request`, `Response`, `Headers`, and `FormData` classes that mirror the browser APIs. The implementation follows the standard, so the MDN Fetch documentation applies as well.
    
    import { fetch, Request, Response, Headers, FormData } from &#39;undici&#39;
    
    const response = await fetch(&#39;https://example.com&#39;)
    const text = await response.text()

When mixing these classes, keep them from the same implementation: use the global `fetch()` with the global `FormData`, `Request`, `Response`, and `Headers`, and use undici&#39;s `fetch()` with undici&#39;s classes. Passing a value created by one implementation to the other can throw.

## `fetch(input[, init])`

  * `input` {string|URL|Request} The resource to fetch. A string or {URL} is treated as the URL to request; a {Request} is used as the request template.
  * `init` {RequestInit} (optional) An options object that customizes the request.
    * `body` {string|Buffer|Uint8Array|Blob|FormData|URLSearchParams|ReadableStream|null} The request body. Default: `null`.
    * `cache` {string} The cache mode. One of `&#39;default&#39;`, `&#39;force-cache&#39;`, `&#39;no-cache&#39;`, `&#39;no-store&#39;`, `&#39;only-if-cached&#39;`, or `&#39;reload&#39;`.
    * `credentials` {string} How credentials are sent. One of `&#39;omit&#39;`, `&#39;include&#39;`, or `&#39;same-origin&#39;`.
    * `dispatcher` {Dispatcher} The {Dispatcher} used to perform the request. Default: the global dispatcher.
    * `duplex` {string} The duplex mode of the request. Must be `&#39;half&#39;` when a streaming `body` is provided.
    * `headers` {Headers|Object|Array} The request headers, as a {Headers} instance, a plain object, or an array of `[name, value]` pairs.
    * `integrity` {string} The subresource integrity metadata of the request.
    * `keepalive` {boolean} Whether the connection may outlive the page. Default: `false`.
    * `method` {string} The request method, for example `&#39;GET&#39;` or `&#39;POST&#39;`.
    * `mode` {string} The request mode. One of `&#39;cors&#39;`, `&#39;navigate&#39;`, `&#39;no-cors&#39;`, or `&#39;same-origin&#39;`.
    * `redirect` {string} How redirects are handled. One of `&#39;error&#39;`, `&#39;follow&#39;`, or `&#39;manual&#39;`.
    * `referrer` {string} The request referrer.
    * `referrerPolicy` {string} The referrer policy. One of `&#39;&#39;`, `&#39;no-referrer&#39;`, `&#39;no-referrer-when-downgrade&#39;`, `&#39;origin&#39;`, `&#39;origin-when-cross-origin&#39;`, `&#39;same-origin&#39;`, `&#39;strict-origin&#39;`, `&#39;strict-origin-when-cross-origin&#39;`, or `&#39;unsafe-url&#39;`.
    * `signal` {AbortSignal|null} An {AbortSignal} used to abort the request. Default: `null`.
    * `window` {null} Can only be `null`; reserved by the standard.
  * Returns: {Promise} Fulfills with a {Response} once the response headers have been received.

Starts the process of fetching a resource from the network and returns a promise that fulfills with a {Response}. The promise rejects only on network failures; an HTTP error status such as `404` still fulfills the promise, so inspect `response.ok` to detect failures.

Cancel unread daemon response bodies.

Node’s supported fetch implementation keeps an undrained response connection occupied until consumption, cancellation, garbage collection, or signal abort. The timeouts bound the hold, but concurrent requests can still create avoidable daemon connection pressure.

♻️ Suggested fix

       const res = await fetch(`${opts.daemonUrl.replace(/\/+$/, "")}/api/whoami?${new URLSearchParams({ sessionName: caller.seat, compact: "1" }).toString()}`,
         { signal: AbortSignal.timeout(5_000) });
+      await res.body?.cancel().catch(() => {});
       if (res.status === 404) return { status: 503, error: "seat_unavailable", message: "This connection's seat isn't on this instance yet.", log: `Cloud named seat ${caller.seat}, which this daemon doesn't have` };
       if (!res.ok) return unavailable(`the seat check for ${caller.seat} answered HTTP ${res.status}`);

       const self = res.ok ? ((await res.json()) as { selfHostId?: unknown }).selfHostId : undefined;
+      if (!res.ok) await res.body?.cancel().catch(() => {});

Check all returned successors before reporting out_of_scope.

If a hidden sibling sorts first and a visible sibling sorts second, this return hides the visible successor. rig_queue_show then cannot name an item the customer may read. Filter the rows first, and return out_of_scope only if no returned successor is visible. Test the hidden-first order as well as the current visible-first order.

Redact internal lineage fields from customer rows.

A team-internal item can be handed to the customer. The resulting row matches the customer scope because its source is a team seat and its destination is the customer seat. Local handoff stores the source ID in handedOffFrom and appends it to chainOfRecord. The customer projection passes both fields through in show, list, and create responses.

Suggested fix

   const fields = { ...(row as Record<string, unknown>) };
+  delete fields.handedOffFrom;
+  delete fields.chainOfRecord;
   if (typeof fields.transitionNote === "string") fields.transitionNote = maskNote(fields.transitionNote, fields.qitemId, names);

[openrig-review]

Approved at 0f93cfe. rig mcp serve --http --cloud-grants <url> takes its grants from OpenRig Cloud: each request's customer key is checked against Cloud for this daemon's own instance, every answer but active is refused with no token-file fallback, and a customer grant sees only its own items and the parties it may see. Claude (dev60-review) and Codex (review50-r2) halves CLEAR at 692d6b2 after two rounds. 0f93cfe adds only the revert of the caller-seat create refusal (78f426b); its patch-id equals that commit's inverse, and that refusal waits on a product decision. Required CI passes at this head.
