The Alchemy plugin for Claude Code bundles everything Claude needs to work with Alchemy in one install: the hosted Alchemy MCP Server, slash commands for common workflows, and Agent Skills that teach Claude how to use Alchemy APIs in code.
The plugin is open source at alchemyplatform/alchemy-claude-plugin.
In Claude Code, run:
/plugin marketplace add alchemyplatform/alchemy-claude-plugin
/plugin install alchemy@alchemyThe first time Claude calls an Alchemy tool, a browser window opens to sign in with your Alchemy account (OAuth). No API key or local install required. If you don't have an account, create one for free at the Alchemy Dashboard.
Run /alchemy:setup to list your Alchemy apps and select one. Most data tools need a selected app. The server caches that app's API key on Alchemy's side for later requests, for up to 90 days.
/alchemy:setupYou're set. Ask Claude things like "What's the current price of ETH?" or "Show me the NFTs owned by vitalik.eth", or use the slash commands below.
| Command | Description |
|---|---|
/alchemy:setup | Connect and select an Alchemy app for the session |
/alchemy:balance <address> [network] | Native + ERC-20 balances with USD values |
/alchemy:nfts <address> [network] | NFTs owned by a wallet |
/alchemy:token <symbol or address> [network] | Token price + metadata |
/alchemy:tx <hash> [network] | Transaction details + receipt |
/alchemy:portfolio <address> [networks] | Multi-chain tokens + NFTs |
/alchemy:gas [network] | Current gas and fee estimates |
/alchemy:solana <pubkey> | SOL balance + SPL token accounts |
/alchemy:create-app <name> <networks> | Create a new Alchemy app |
Networks default to eth-mainnet when you don't specify one.
- 170+ MCP tools from the hosted Alchemy MCP Server (
mcp.alchemy.com): EVM JSON-RPC, Token, NFT, Prices, and Portfolio APIs, transaction simulation and tracing, Alchemy app management, and Solana (RPC + Digital Asset Standard). See the full tool list. The plugin's connection hides the faucet, airdrop, and paymaster tools. - Slash commands for the workflows above, so common queries are one command away.
- Agent Skills (
alchemy-mcpandalchemy-api) that teach Claude how to use Alchemy correctly — both for live queries in the conversation and when writing application code against Alchemy APIs.
The plugin reads blockchain data, simulates transactions, and manages your Alchemy apps. It doesn't send transactions, swap, bridge, make payments, or sign with a wallet.
Plugin versions before 0.2.0 also bundled the alchemy-cli and agentic-gateway skills. To keep using them, install them from Agent Skills.
| Best for | |
|---|---|
| Claude Plugin | Claude Code — one install that bundles the MCP server, slash commands, and skills |
| MCP Server | Any MCP-compatible client (Cursor, Codex, Claude Desktop, VS Code Copilot) — live blockchain data as tool calls |
| Agent Skills | Any agent that writes code against Alchemy APIs — endpoint knowledge without tool calls |
If you use Claude Code, the plugin gives you the MCP server, slash commands, and the alchemy-mcp and alchemy-api skills in one install.
The plugin connects to Alchemy's hosted MCP server and APIs. Data collection, usage, retention, and sharing practices are described in the Alchemy Privacy Policy. The plugin stores no data locally beyond what Claude Code persists for the connection; the server caches the selected app's API key on Alchemy's side for up to 90 days, and clears it if your sign-in becomes invalid.
