Alchemy Agent Skills are plug-and-play knowledge packages for AI coding agents. Install them with a single command, and your agent knows how to use every Alchemy API including endpoints, authentication, pagination, error handling, and more.
npx skills add alchemyplatform/skills --yes- Two skills included:
alchemy-api(API key auth) andagentic-gateway(wallet-based x402 auth when no API key is set) - Works with Claude Code, Codex, Cursor, VS Code Copilot, and other agents that support the skills spec
Get started with Agent Skills →
The Alchemy MCP Server exposes our APIs through the Model Context Protocol, giving AI tools direct access to blockchain data as tool calls.
- 11+ blockchain tools including token prices, NFT data, transaction history, balances, and more
- 50+ supported chains
- Works with Claude Desktop, Claude Code, Cursor, VS Code Copilot, and Windsurf

Your agent can authenticate with a crypto wallet instead of an API key, purchasing credits with USDC via the x402 payment protocol. This is what the agentic-gateway skill teaches your agent automatically.
- 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

| I want to... | Use |
|---|---|
| Give my AI coding agent knowledge of all Alchemy APIs | Agent Skills |
| Let my IDE copilot query live onchain data during a conversation | MCP Server or Agent Skills |
| Build an autonomous agent that authenticates with a wallet and purchases credits with USDC | Agent Skills + Agent Authentication and Payment |
| Give my coding agent API knowledge and live data access | Agent Skills + MCP Server |
These tools are complementary. For example, an agent using Skills to understand our API surface can also connect to the MCP Server to query live data, or use the agentic-gateway skill to operate autonomously without a pre-provisioned API key.
