AElf Node Skill

English | 中文

AElf Node Skill provides MCP, CLI, and SDK interfaces for AElf public nodes with REST for reads, SDK for contract execution, and selective fallback for fee estimate, plus OpenClaw and IronClaw integration.

Features

• Read: chain status, block height, block detail, transaction result

• Contract metadata: view methods and system contract address (REST adapter)

• Contract execution: view call and send transaction (SDK)

• Fee estimate: REST first, SDK fallback

• Node registry: import and list custom nodes

Default Nodes

• AELF: https://aelf-public-node.aelf.io

• tDVV: https://tdvv-public-node.aelf.io

Install

bun install

Usage

MCP

bun run mcp

CLI

bun run cli get-chain-status --chain-id AELF

OpenClaw

bun run build:openclaw
bun run build:openclaw:check

Quick Start

# MCP server
bun run mcp

# CLI
bun run cli get-chain-status --chain-id AELF

# Unit tests
bun run test:unit

Setup CLI

This repository includes a one-command setup CLI for Claude, Cursor, OpenClaw, and IronClaw.

bun run setup claude
bun run setup cursor
bun run setup cursor --global
bun run setup ironclaw
bun run setup openclaw
bun run setup openclaw --config-path /path/to/openclaw-config.json
bun run setup list
bun run setup uninstall claude
bun run setup uninstall cursor --global
bun run setup uninstall ironclaw
bun run setup uninstall openclaw --config-path /path/to/openclaw-config.json

IronClaw

bun run setup ironclaw
bun run setup uninstall ironclaw

The IronClaw setup writes a stdio MCP entry to ~/.ironclaw/mcp-servers.json and installs this repo's SKILL.md to ~/.ironclaw/skills/aelf-node-skill/SKILL.md.

Important trust model note:

• Use the trusted skill path above for write-capable flows such as aelf_send_contract_transaction.

• Do not rely on ~/.ironclaw/installed_skills/ for the primary install path when you need write approval behavior.

• This MCP server emits both standard MCP camelCase annotations and IronClaw-compatible snake_case annotations so the current IronClaw source can honor read/write hints.

Remote activation contract:

• GitHub repo/tree URLs are discovery sources only, not the final IronClaw install payload.

• Preferred IronClaw activation from npm: bunx -p @blockchain-forever/aelf-node-skill aelf-node-setup ironclaw

• Prefer ClawHub / managed install for OpenClaw when available; otherwise use bunx -p @blockchain-forever/aelf-node-skill aelf-node-setup openclaw

• Local repo checkout remains a development smoke-test path only.

Minimal smoke test:

1. bun run setup ironclaw

2. Ask IronClaw for latest block height on AELF

3. Ask it to send a contract transaction and confirm approval appears before execution

Installed package users can also run:

aelf-node-setup claude

MCP Config Example

Reference file: mcp-config.example.json

{
  "mcpServers": {
    "aelf-node-skill": {
      "command": "bun",
      "args": ["run", "/ABSOLUTE/PATH/TO/src/mcp/server.ts"],
      "env": {
        "AELF_PRIVATE_KEY": "optional_env_fallback_private_key",
        "PORTKEY_WALLET_PASSWORD": "optional_wallet_password",
        "PORTKEY_CA_KEYSTORE_PASSWORD": "optional_keystore_password"
      }
    }
  }
}

Environment

Copy and edit:

cp .env.example .env

• AELF_PRIVATE_KEY: optional env fallback for write operations (highest env priority)

• PORTKEY_PRIVATE_KEY: optional secondary env fallback for shared-skill compatibility

• Write tools (aelf_send_contract_transaction, aelf_estimate_transaction_fee) resolve signer as explicit -> context -> env

• PORTKEY_WALLET_PASSWORD: optional password cache for EOA wallet context

• PORTKEY_CA_KEYSTORE_PASSWORD: optional password cache for CA keystore context

• PORTKEY_SKILL_WALLET_CONTEXT_PATH: optional override for active context path (~/.portkey/skill-wallet/context.v1.json)

• signerMode=daemon is reserved and currently returns SIGNER_DAEMON_NOT_IMPLEMENTED

• AELF_NODE_AELF_RPC_URL: optional override for AELF node

• AELF_NODE_TDVV_RPC_URL: optional override for tDVV node

• AELF_NODE_REGISTRY_PATH: optional custom registry path

• AELF_SDK_INSTANCE_CACHE_MAX: optional max SDK instance cache size (default 32)

• AELF_SDK_CONTRACT_CACHE_MAX: optional max SDK contract cache size (default 256)

• AELF_REST_CLIENT_CACHE_MAX: optional max REST client cache size (default 64)

Security

• Never put AELF_PRIVATE_KEY in prompts or channel outputs.

• Active wallet context must not contain plaintext private keys.

• Use environment variables for all secrets.
