Stellar MCP Server for XDR

A Claude Model Context Protocol (MCP) server that decodes Stellar XDR into XDR-JSON, that agents can use to understand what XDR means.

Usage (General)

To use with agents, setup a stdio MCP configuration with your agent calling the following command:

{
  "command": "npx",
  "args": ["deno", "run", "--allow-read", "https://github.com/leighmcculloch/mcp-stellar-xdr/raw/refs/heads/main/mcp-stellar-xdr.ts"]
}

If you have deno installed you can omit the npx command and call deno directly.
