We ship four tools for building with AI on Alchemy. They're complementary, and most agent-driven workflows use two or three of them together.
Alchemy Agent Skills are plug-and-play knowledge packages for AI coding agents. Install them once, and your agent knows every Alchemy endpoint, authentication method, pagination rule, and error pattern without manual prompting.
npx skills add alchemyplatform/skills --yes- Two skills included:
alchemy-api(API key auth) andagentic-gateway(x402 gateway auth) - Works with Claude Code, Codex, Cursor, VS Code Copilot, and any agent that supports the skills spec

The Alchemy CLI is a single binary that wraps every Alchemy product. Use it for live querying, admin tasks, and local automation, or give it to an AI agent as a structured shell tool.
npm i -g @alchemy/cli@latest- Covers JSON-RPC nodes, Data APIs, Wallet APIs, Notify webhooks, and the Admin API across 100+ networks
--json --no-interactiveflags make every command machine-readable- Built-in
agent-promptcommand emits a complete usage spec for AI agents - Supports API key, access key, and x402 gateway auth for Alchemy APIs
- Pays compatible x402 v2 third-party APIs in USDC with x402 payments (
alchemy x402 request)
The Alchemy MCP Server exposes our APIs through the Model Context Protocol, so AI tools can fetch blockchain data as tool calls inside a conversation.
claude mcp add alchemy --transport http https://mcp.alchemy.com/mcp- 159 tools across token prices, NFT metadata, transaction history, simulation, tracing, account abstraction, Solana DAS, and more
- 100+ supported networks
- Hosted at
https://mcp.alchemy.com/mcpwith OAuth, no API key or local install required

Your agent can authenticate with a crypto wallet instead of an API key, purchasing Alchemy credits in USDC via the x402 payment protocol. This is what the agentic-gateway skill teaches your agent automatically, and what the CLI uses when you pass --x402.
- No API key required, supports authentication via SIWE (Sign-In With Ethereum) and SIWS (Sign-In With Solana)
- Supports payment via USDC on Base and Solana
- Wallet type is independent of which chain you query

To have your agent pay an x402 v2 endpoint that offers a supported EVM payment option, use the CLI's x402 payments instead.
| I want to... | Use |
|---|---|
| Give my AI coding agent knowledge of all Alchemy APIs | Agent Skills |
| Run quick onchain queries or admin tasks from the terminal | CLI |
| Script a recurring job, cron, or CI step that calls Alchemy | CLI |
| Give a shell-driven agent a structured tool surface | CLI with --json --no-interactive |
| Let my IDE copilot query live onchain data during a conversation | MCP Server or CLI |
| Build an autonomous agent that authenticates with a wallet and pays Alchemy in USDC | Wallet auth for Alchemy APIs plus Skills or CLI |
| Pay a compatible x402 v2 third-party API in USDC | x402 payments via the CLI |
| Give a coding agent both API knowledge and live data access | Agent Skills + MCP Server or CLI |
These tools layer on top of each other. An agent using Skills to understand our APIs can shell out to the CLI for admin tasks, call the MCP Server for live data, use the agentic-gateway skill or --x402 flag to operate without a pre-provisioned API key, and use alchemy x402 to pay third-party APIs in USDC.
| Tool | Skills | CLI | MCP Server | Agent Auth |
|---|---|---|---|---|
| Claude Code | Yes | Yes | Yes | Yes |
| Cursor | Yes | Yes | Yes | Yes |
| Codex | Yes | Yes | Yes | Yes |
| VS Code Copilot | Yes | Yes | Yes | — |
| Claude Desktop | Yes | Yes | Yes | — |
The CLI works with any agent that can run shell commands, so the table above is a non-exhaustive list of the agents we test against.
