Attacks that exploit this kind of access
The rule that runs manifest_cancelOrder 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 manifest_cancelOrder, this is the rule to start with:
manifest_cancelOrder is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
The button opens the PolicyLayer dashboard: create your workspace, connect Sap, apply this rule, and every manifest_cancelOrder call is checked against it from then on.
Questions about manifest_cancelOrder
Cancel a limit order on a Manifest market. SAP MCP context: This Synapse AgentKit tool is served beside the sap_* SDK tools. Use sap_agent_identity_plan, sap_payments_register_agent, sap_payments_update_agent, and sap_publish_tool_by_name when the capability should become part of an on-chain SAP agent profile or tool registry entry. SAP MCP execution guidance: Intent: SAP MCP tool 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 Destructive tool in the Sap MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
manifest_cancelOrder accepts 3 parameters: wallet, orderId, marketId. Required: wallet, orderId, marketId. The full parameter table on this page comes from the server's own tool schema.

manifest_cancelOrder is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the manifest_cancelOrder rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for manifest_cancelOrder. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
manifest_cancelOrder is provided by the Sap MCP server (https://mcp.sap.oobeprotocol.ai/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
