Get list of all supported collaterals with their current allocations, limits, and oracle prices. Shows the composition backing USDs.
AI agents call vault_get_collaterals to retrieve information from BNB Chain MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays read-only data about collateral allocations, limits, and oracle prices. It performs no state-changing operations, executes no code, deletes nothing, and moves no money. Even in the context of a financial protocol (Sperax), it is a passive query operation that an AI agent could misuse only through information disclosure or spam, neither of which presents significant blast radius.
From the tool's definition Tool description states it 'Get[s] list of all supported collaterals' and 'Shows the composition backing USDs' — these are purely informational retrieval operations with no modification, deletion, execution, or financial transaction capability.
Documented attack patterns abuse exactly the kind of access vault_get_collaterals gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and BNB Chain MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for vault_get_collaterals:
{
"version": "1",
"default": "deny",
"tools": {
"vault_get_collaterals": {}
}
}vault_get_collaterals is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get list of all supported collaterals with their current allocations, limits, and oracle prices. Shows the composition backing USDs. It is categorised as a Read tool in the BNB Chain MCP MCP Server, which means it retrieves data without modifying state.
Register the BNB Chain MCP server in PolicyLayer and add a rule for vault_get_collaterals: 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 BNB Chain MCP. Nothing to install.
vault_get_collaterals 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 vault_get_collaterals 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 vault_get_collaterals. 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.
vault_get_collaterals is provided by the BNB Chain MCP server (nirholas/bnbchain-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
