AI agents use beacon_gas_deposit to commit financial operations through RustChain + BoTTube MCP Server — usually the final step of a payment, billing, or trading workflow. A call moves real money.
This tool commits financial obligations by transferring RTC tokens from one account to another. RTC is a blockchain token with monetary value on the RustChain platform. Misuse by an AI agent could result in unauthorized token transfers, drainage of wallets, or fraudulent financial transactions. The presence of an 'admin_key' authorization mechanism indicates this is a privileged financial operation.
From the tool's definition Tool enables depositing RTC (cryptocurrency tokens) to an agent's gas balance, which represents a direct movement of financial value.

PolicyLayer is an MCP gateway — it sits between your AI agents and RustChain + BoTTube MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for beacon_gas_deposit:
{
"version": "1",
"default": "deny",
"tools": {
"beacon_gas_deposit": {
"deny_if": [
{
"conditions": [],
"on_deny": "Requires human approval."
}
]
}
}
}Any call to beacon_gas_deposit is blocked until a human approves it. The rest of the server keeps working.

Register the RustChain + BoTTube MCP Server MCP server in PolicyLayer and add a rule for beacon_gas_deposit: 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 RustChain + BoTTube MCP Server. Nothing to install.
beacon_gas_deposit is a Financial tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the beacon_gas_deposit 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 beacon_gas_deposit. 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.
beacon_gas_deposit is provided by the RustChain + BoTTube MCP Server MCP server (scottcjn/rustchain-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
