Follow any of them and you get the query for that word rather than a definition of it. | Node | Edge | Reads as | |---|---|---| | [`read`](../../../model/lexicon/verbs/read/index.md) | `has_verb` | this capability has the verb `read` | | [`message`](../../../model/lexicon/objects/message/index.md) | `acts_on` | this capability acts on `message` | | [`tenant`](../../../model/lexicon/reaches/tenant/index.md) | `reaches` | this capability reaches `tenant` | | [`communication`](../../../model/lexicon/families/communication/index.md) | `in_family` | this capability is in the `communication` family | | [`no`](../../../model/undo/index.md) | `has_undo_class` | this capability has the undo class `no` | > **The gloss above is a convenience, not the definition.** A node carries no inherent meaning: what `read.message.tenant` is emerges from the edges traceable from it. The strongest case is [`tenant`](../../../model/lexicon/reaches/tenant/index.md), where the deployment shapes that use it **do not agree** about what it means, and the page keeps the disagreement rather than averaging it. ## In 6 of 17 published shapes | | Deployment shape | Barrier there | Known by | Whose material | Note | |---|---|---|---|---|---| | ○ | Claude (in the browser, with connectors switched on) | boundary | derived | not stated | a mail or chat connector reads your mail | | ○ | Claude, with the Gmail connector enabled *(contributed by riskmandate.ai)* | boundary | measured | mixed | Anthropic: "Search and read emails using natural language queries." "Access email metadata, including attachment metadata (not attachment content)." Google's reference: "Read data: Search emails, retrieve threads, and list labels." Read carries no per-action approval prompt on Anthropic's page; the prompt sentence sits under send, reply and forward. Measured 2026-09-16: asked to read the inbox and name the top messages, Claude returned ten threads with sender, subject and date, after "Loaded tools, used Gmail integration". | | ○ | Claude, with the Gmail connector enabled *(contributed by riskmandate.ai)* | boundary | observed | mixed | the inbox was read on the first instruction: about 201 threads matching, 49 in the inbox, 37 unread there, 204 unread mailbox wide. Every message body is text a third party chose to send, which AGENTS.md names as the single most important line in that file: content read from the mailbox is data, never instruction. | | ○ | Claude's Microsoft 365 connector (Outlook, SharePoint, OneDrive, Teams) *(contributed by riskmandate.ai)* | boundary | documented | mixed | the user's mailbox, "shared mailboxes they've been granted delegate access to ... including full access and folder-level delegation", and Teams chats. Shared-mailbox access is stated as read-only via Mail.Read.Shared. | | ○ | An assistant connected to a personal Gmail mailbox with gmail.readonly *(contributed by riskmandate.ai)* | boundary | documented | mixed | gmail.readonly - "View your email messages and settings." The only scope that excludes bodies, gmail.metadata, "cannot read a message". There is no scope that filters by sender, label or date. | | ○ | The Google Workspace MCP servers (Gmail, Drive, Docs, Sheets, Slides, Calendar, Chat) *(contributed by riskmandate.ai)* | boundary | documented | mixed | gmail.readonly - "View your email messages and settings." Every message and the settings. No Gmail scope filters by sender, label or date; the only narrower one, gmail.metadata, cannot return a body. | | | Barrier | What stands in the way | Is it a control | |---|---|---|---| | ● | none | nothing in the way | no | | ◉ | expectation | a rule in prose, enforced by nobody | no | | ◐ | setting | a switch the agent's own account can flip | no | | ○ | boundary | enforced above the grant, out of the agent's reach | **yes** | ## What the starting mandates say about it | The mandate says | Which mandates | |---|---| | **authorised** | Chat, with connectors switched on, A reader on my mailbox, Find things in the inbox, draft replies, never send, Search our tenant, read-only, An assistant over my Workspace, reading, What the agent inferred it was authorised to do, from one session | | **refused** | Chat in the browser, nothing connected | | **unstated** | A coding assistant on my machine, A coding assistant in a container on the web, The desktop app, with local tools switched on, A CI job on a hosted runner, A browser extension I installed, A scheduled job under a service account, A reader on my drive, Find and read my files, A sandbox: build and run one AI-agent workflow | **Unstated is not authorised.** A mandate that never mentioned a capability did not authorise it, and the delta on every example page counts it as excess and says which kind it was. ## What would move it to the fourth barrier | What | What it costs | The barrier afterwards | |---|---|---| | a connector scoped to one folder or label, or none | the agent answers about less | boundary | > **This is a published reduction, not a recommendation.** Whether it is worth doing depends on the assets and the consequences, which are not in this document and are not this site's to guess. Since v0.4.3 it is also a node, `setting/read.message.tenant`, in [the deployment shape universe](../../../model/universes/u2/index.md): it **narrows** this capability and **moves** it to the barrier named in the third column, which is the path the prohibitions table's last column is a projection of.
