Unstake a StarGate NFT to burn it and retrieve the staked VET
AI agents call unstake_stargate_nft to retrieve information from VeChain AI Terminal MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Even though unstake_stargate_nft only reads data, uncontrolled read access leaks sensitive information and racks up API costs — an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Attacks that exploit this kind of access
Unstake a StarGate NFT to burn it and retrieve the staked VET. It is categorised as a Read tool in the VeChain AI Terminal MCP Server MCP Server, which means it retrieves data without modifying state.
Register the VeChain AI Terminal MCP Server MCP server in PolicyLayer and add a rule for unstake_stargate_nft: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches VeChain AI Terminal MCP Server. Nothing to install.
unstake_stargate_nft is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the unstake_stargate_nft 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 unstake_stargate_nft. 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.
unstake_stargate_nft is provided by the VeChain AI Terminal MCP Server MCP server (vechain-ai-terminal/vechain-terminal-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
