Calculate proposal ID from proposal parameters
AI agents call calculate_proposal_id 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 performs a deterministic calculation based on input parameters to derive a proposal identifier. It has no side effects, does not retrieve from or write to a blockchain, does not trigger external operations, and does not move funds or delete data. It is a pure read/compute operation that would be classified as 'Read' per the guidelines, as it involves deriving information without state modification.
From the tool's definition The tool 'calculate_proposal_id' is described as calculating a proposal ID from proposal parameters. This is a computational/derivation operation that takes inputs and produces an output without modifying state, executing external commands, or affecting data…
Documented attack patterns abuse exactly the kind of access calculate_proposal_id 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 calculate_proposal_id:
{
"version": "1",
"default": "deny",
"tools": {
"calculate_proposal_id": {}
}
}calculate_proposal_id is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Calculate proposal ID from proposal parameters. 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 calculate_proposal_id: 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.
calculate_proposal_id 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 calculate_proposal_id 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 calculate_proposal_id. 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.
calculate_proposal_id 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.
