algorand-mcp: Instructions file for Codex

AGENTS.md

algorand-mcp AGENTS.md is an instructions file for Codex, OpenCode from GoPlausible/algorand-mcp. It costs 5,347 tokens per session, scanned A, original, MIT.

A guide for using an Algorand MCP server, a local service that lets an AI agent work with the Algorand blockchain. It covers wallets, networks such as mainnet and testnet, transactions, tools, and amount decimals.

In plain words
What is it for?
Use it when querying wallets, reading blockchain data, creating or signing transactions, or calling Algorand MCP tools on mainnet, testnet, or localnet.
Why use it?
It explains the safety-sensitive details of blockchain operations, including where signing keys are kept and how to select the correct network and amount.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

algorand-mcp AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Algorand MCP — Agent Guide

This document describes how AI agents should interact with the Algorand blockchain through the Algorand MCP server. It covers tool usage patterns, transaction workflows, safety rules, and common pitfalls.

Overview

Algorand MCP is a local MCP server that runs on the user's machine. It provides 126 tools across 15 categories for full Algorand blockchain access. Mnemonics are stored in a local SQLite agent-wallet DB (~/.algorand-mcp/wallet.db, mode 0600) — they never appear in tool responses, logs, or MCP messages. The MCP server holds the keys and signs on the agent's behalf.

Key difference from remote MCP servers: This server runs locally, signing happens on the user's machine using mnemonics held in the agent-wallet DB, and the agent provides the network parameter (mainnet, testnet, or localnet) on each tool call.

Calling MCP Tools

MCP tools are deferred — you MUST use ToolSearch to load them before calling:

ToolSearch("+algorand wallet")                                    # Search by keyword — loads matching tools
ToolSearch("select:mcp__algorand-mcp__wallet_get_info")           # Load a specific tool by full name

Once loaded, call them normally:

mcp__algorand-mcp__wallet_get_info { "network": "testnet" }

Full tool name pattern: mcp__algorand-mcp__<tool_name>. If you get "tool not found", use ToolSearch("+algorand <keyword>") to load it first.

Session Start

At the beginning of every Algorand session:

  1. Load tools — Call ToolSearch("+algorand wallet") to load wallet tools
  2. Check wallet — Call wallet_get_info with the target network to verify a wallet account exists and is active.
  3. If no accounts — Guide the user to create one with wallet_add_account (sets the nickname).
  4. If account needs funding — Generate an ARC-26 QR code with generate_algorand_qrcode (returns { qr, uri, link, expires_in } — display the qr text and shareable link) or direct the user to the testnet faucet: https://lora.algokit.io/testnet/fund
  5. If account needs USDC funding — Direct to testnet USDC faucet: https://faucet.circle.com/

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
