RECOMMENDED RULE

The rule that runs 3land_listForSale safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Sap, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For 3land_listForSale, this is the rule to start with:

3land_listForSale Rate-limited

3land_listForSale stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about 3land_listForSale

What does the 3land_listForSale tool do? +

List an NFT for sale on 3.Land in any SPL token. SAP MCP context: Protocol 3land; operation class write. Use for 3.Land NFT collection, minting, listing, cancellation, and purchase flows. Confirm marketplace price, seller/buyer wallet, collection, and listing state before writes. Pair marketplace actions with SAP registry metadata only when the marketplace asset is part of the agent identity or service catalog. SAP MCP execution guidance: Intent: read/discovery workflow. Pricing: paid read-premium; estimate first, then use sap_payments_call_paid_tool when the runtime cannot replay x402 natively. Routing: hosted accountless write is blocked; do not call this as a paid hosted write and no x402 payment should be charged. Use the local sap_payments bridge or a hosted unsigned builder when user signing is required. Signer boundary: user-controlled local profile or external signer; OOBE hosted MCP remains non-custodial. It is categorised as a Write tool in the Sap MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

3land_listForSale accepts 5 parameters: mint, price, expiry, seller, priceMint. Required: mint, price, seller. The full parameter table on this page comes from the server's own tool schema.
