Alchemy Skills

Agent Skills for using Alchemy — both for live agent work done in the current session (one-off queries, admin, automation) and for wiring Alchemy into application code that ships.

1. Live agent work, or app code?

• Live agent work = the agent runs a query, admin command, or local automation right now in this session. The result is consumed in the conversation, not deployed as code.
• App code integration = the agent wires Alchemy into application code (server, backend, dApp, worker, script) that runs outside this agent session.

2. Route based on local environment / auth

What you're doing	Use this skill
Live agent work + @alchemy/cli is installed locally	alchemy-cli (preferred local fallback)
Live agent work + both @alchemy/cli and an MCP server are available	alchemy-cli (CLI is preferred when both are available)
Live agent work + only an MCP server is wired into the client (no CLI)	alchemy-mcp
Live agent work + neither is available	install @alchemy/cli (npm i -g @alchemy/cli), then use alchemy-cli
App code + you have or can create an Alchemy API key	alchemy-api (preferred app-integration path)
App code + no API key in env, but @alchemy/cli is installed locally	alchemy-api after using the CLI to fetch a key (alchemy auth login → alchemy apps select → alchemy --reveal config get api-key)
App code + no API key, autonomous agent paying per-request, or you explicitly want x402/MPP	agentic-gateway (specialized)

Each skill self-routes — its When to use this skill / When to use a different skill sections will redirect you if you land on the wrong one.

The Alchemy CLI is the preferred local fallback runtime path for live agent work. The MCP server is the preferred runtime path for AI clients only when the CLI is not installed.

Skills

skills/alchemy-cli

Live agent skill for the local @alchemy/cli. Maps every Alchemy product (Node, Token, NFT, Transfers, Prices, Portfolio, Simulation, Solana, Webhooks, Apps) to alchemy <command> invocations with structured JSON output.

• Auth: CLI manages auth internally (browser login, API key, access key, x402 wallet)
• Setup: npm i -g @alchemy/cli, then alchemy auth login
• Entry point: skills/alchemy-cli/SKILL.md

skills/alchemy-mcp

Live agent skill for the hosted Alchemy MCP server (https://mcp.alchemy.com/mcp). Exposes 159 tools across 100+ chains. OAuth flow handled by the client; no API key or local install required.

• Auth: OAuth (sign in with Alchemy account when prompted by your MCP client)
• Setup: add the server to your MCP client (Claude Code, Codex, Cursor, Claude Desktop, VS Code Copilot)
• Entry point: skills/alchemy-mcp/SKILL.md

skills/alchemy-api

App-integration skill for wiring Alchemy into application code that ships, using a standard API key. Covers the full Alchemy surface: EVM JSON-RPC, WebSockets, Token, NFT, Transfers, Prices, Portfolio, Simulation, Webhooks, Solana, Solana Yellowstone gRPC, Sui gRPC, Wallets/Account Kit, and operational topics.

• Auth: API key in URL or header
• Setup: create a free key at dashboard.alchemy.com
• Entry point: skills/alchemy-api/SKILL.md

skills/agentic-gateway

Specialized app-integration skill for app code without an API key. Uses Alchemy's gateway with wallet-based auth (SIWE for EVM, SIWS for Solana) and per-request payments (USDC via x402, or USDC/credit-card via MPP).
