Fetch B3TR actions for a VeBetterDAO app via /api/v1/b3tr/actions/apps/{appId}. Requires appId (if coming from app-hub from name or description, use veBetterDaoId).
AI agents call getB3TRActionsForApp to retrieve information from VeChain MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Even though getB3TRActionsForApp 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
Fetch B3TR actions for a VeBetterDAO app via /api/v1/b3tr/actions/apps/{appId}. Requires appId (if coming from app-hub from name or description, use veBetterDaoId). It is categorised as a Read tool in the VeChain MCP Server MCP Server, which means it retrieves data without modifying state.
Register the VeChain MCP Server MCP server in PolicyLayer and add a rule for getB3TRActionsForApp: 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 MCP Server. Nothing to install.
getB3TRActionsForApp 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 getB3TRActionsForApp 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 getB3TRActionsForApp. 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.
getB3TRActionsForApp is provided by the VeChain MCP Server MCP server (vechain/vechain-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
