AI agents call getIPFSContent 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 getIPFSContent 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 content from IPFS using the VeChain gateway proxy (api.gateway-proxy.vechain.org). Provide an IPFS Content Identifier (CID) to retrieve the associated data. Commonly used to fetch B3TR proposal descriptions. IMPORTANT: Proposal descriptions often contain Discourse forum links (vechain.discourse.group/t/topic-name/TOPIC_ID or discourse.vebetterdao.org/t/topic-name/TOPIC_ID). After fetching IPFS content, search for these links and extract them. If getDiscourseTopic is available, use it with the topic ID. If not available (optional feature), provide the full forum URL for manual viewing to see community discussion and sentiment. 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 getIPFSContent: 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.
getIPFSContent 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 getIPFSContent 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 getIPFSContent. 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.
getIPFSContent 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.
