MERX MCP

Overview

MERX MCP is a community MCP server for TRON infrastructure, listed in the MCP Registry, that runs either as a hosted SSE endpoint or locally over stdio. It exposes tools for TRON energy and bandwidth pricing, resource optimization, and TRC-20 stablecoin payment workflows. An agent builder plugs it in to give an agent TRON resource-cost awareness and stablecoin payment handling without integrating TRON APIs directly.

Live probe verifies the interface responds — not what the tools do, their safety, or their output quality. The call is one read-only tool named by this server's own list (list_/get_/search_, no mutating verb anywhere in the name, no required arguments and none that look like a key, an address or an amount), asked once a day with no arguments. Not asked is not a failure.
