Algorand Remote MCP

A Model Context Protocol (MCP) server that provides tools and resources for AI agents to interact with the Algorand blockchain. Built on Cloudflare Workers with HashiCorp Vault-based wallet management and multi-provider OAuth authentication.

Overview

Algorand Remote MCP bridges AI agents and the Algorand blockchain ecosystem through a standardized MCP interface. It enables AI systems to manage wallets, create and submit transactions, swap tokens via DEX aggregators, and access blockchain data — all without requiring deep blockchain expertise.

This is a remote MCP implementation running on Cloudflare Workers with:

HashiCorp Vault for secure Ed25519 key storage and transaction signing
Multi-provider OAuth (Google, GitHub, Twitter, LinkedIn) for user authentication
algosdk v3.5.2 for Algorand SDK operations
Haystack Router for best-price DEX aggregation across Tinyman, Pact, Folks, and LST protocols
Tinyman SDK for direct DEX swap operations
Alpha Arcade SDK for prediction market trading (orderbooks, limit/market orders, positions)

Quick Start

Prerequisites: Node.js v16+, an OAuth account (Google, GitHub, Twitter, or LinkedIn)

Add to your MCP client configuration:

{
  "mcpServers": {
    "algorand-remote-mcp": {
      "command": "npx",
      "args": [
        "mcp-remote",
        "https://algorandmcp.goplausible.xyz/sse"
      ]
    }
  }
}

Restart your LLM agent and prompt:

Read Algorand MCP skill.
