Part of the Aibtc MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents use transfer_rune to initiate financial transactions through Aibtc. Financial operations involve real money and are irreversible once processed. Intercept blocks financial tools by default, requiring explicit human approval with transaction-level limits to prevent unauthorised spending.
transfer_rune moves real money. Without a policy, an autonomous agent could initiate transactions that drain accounts or exceed budgets. Intercept blocks financial tools by default, requiring human-in-the-loop approval with configurable spending limits per transaction and per time window.

Transfer runes to a recipient address using Runestone OP_RETURN encoding. Builds a Bitcoin transaction with a Runestone, sends runes to the recipient, and returns remaining runes to the sender Taproot address. Requires wallet to be unlocked. Amount is in smallest rune units (raw integer). Uses Unisat indexer to fetch rune UTXOs (UNISAT_API_KEY recommended).. It is categorised as a Financial tool in the Aibtc MCP Server, which means it involves financial transactions. Block by default and require explicit approval.
Add a rule in your Intercept YAML policy under the tools section for transfer_rune. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Aibtc MCP server.
transfer_rune 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 transfer_rune rule in your Intercept 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 Intercept policy for transfer_rune. 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.
transfer_rune is provided by the Aibtc MCP server (@aibtc/mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
