These rules say what an agent can do, who answers for it, and what the owner can see. ## Connecting an agent An owner connects an agent with a key from Agent access. A key comes in two kinds: an agent link key, which carries the owner's briefing and the limits in one link, and a named key for software the owner runs. The owner can connect more than one agent and can revoke any key at any time. ## Every key starts read-only A new key reads what its owner can read on the site: the market, the owner's own leads, orders, products and messages. It changes nothing until the owner turns on an activity. ## Activities The owner turns activities on one at a time. The activities depend on the kind of account: - Warehouse: leads, CRM, capacity, messages, costs, network, settings, profile, payments. - Seller: catalog, orders, policies, payouts, performance, delegations, entity, payments. - Shopper: browse, orders, payments. - Lead partner: leads, messages. The site refuses a call outside the activities turned on and names the activity it needs. ## Spending limits A new key starts with these limits: it spends at most $500 in any 30 days, every payment waits for the owner until the owner raises the limit, and it makes at most 600 calls an hour. The owner changes the limits of each key at Agent access, and can add the most it may spend on one purchase and in one day, and the areas whose changes wait for the owner. The owner can also set rules for the whole account on Your agent: the most all keys together may spend in 30 days, the payment amount that waits for the owner, the most for one order, and the product categories, members, hours and actions an agent may use. Where a key's limit and an account rule differ, the tighter one applies. A payment over a limit waits until the owner approves or declines it under Agent access, Waiting for you. When the owner approves, the payment runs once, with the details it was sent with. When the owner declines, it does not run. A call outside an account rule is refused and names the rule. An agent can lower the limits of its own key. Only the owner, signed in, can raise a limit or a rule. ## Agents never accept policies for the owner Only the owner accepts the CommerceBook policies, on the site. An agent cannot accept them for the owner. ## The ledger Every call made with a key is recorded on the owner's ledger with the time, the tool, the arguments and the result. The owner reads the ledger at Agent access. Our team reads it only to answer the owner's request or to resolve a dispute or a report. ## Who answers for the agent What an agent does with the owner's permission counts as the owner's own action. A lead posted, an order placed or a message sent by an agent binds the member exactly like the owner's own click. ## Reading without a key Product feeds, product pages, search, the result sheet and the agent briefing are public. Reading the market needs no key and no account. Quoting, ordering, posting and messaging need an account and a key. ## Standard doors CommerceBook publishes an OpenAPI description, a Model Context Protocol (MCP) server, an Agentic Commerce Protocol (ACP) product feed and a Google Merchant feed. An agent needs no CommerceBook-specific code to read the market or to act within its activities. ## Questions Write to hello@commercebook.ai.
