It performs a read-only operation on Bitcoin blockchain data with no side effects, no code execution, and no financial transactions. Even though it interacts with blockchain data, the actual operation is a simple lookup/retrieval.

From the tool's definition Tool returns metadata for Rune assets including name, symbol, divisibility, and genesis transaction. Uses 'Returns' verb indicating data retrieval with no modification or execution capability.

How to control mkt-dex

PolicyLayer is an MCP gateway — it sits between your AI agents and Maestro MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for mkt-dex:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "mkt-dex": {}
  }
}

mkt-dex is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

  1. Create a free account and register Maestro MCP Server — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.
