## What it does

The skill covers talking to `https://mcp.alchemy.com/mcp` from inside an agent session. It ships a catalog of 159 tools: Alchemy app administration, EVM JSON-RPC, Token API, transaction simulation, Trace and Debug APIs, ERC-4337, plus Solana RPC and DAS.

The order matters. Call `list_apps` first, then `select_app` with an app ID — skip that and the RPC and Data tools stay dead, since the server caches the key of whichever app you picked. After that, call what you need: `getTokenPricesBySymbol`, `getNFTsForOwner`, `simulateAssetChanges`, `solana_getBalance`. No app yet? `create_app` makes one.

OAuth handles sign-in; the client opens a browser on the first tool call. No API key, nothing to install locally. This is not for code you ship — use `alchemy-api` with a key or `agentic-gateway` without one. And if `@alchemy/cli` is already on the machine, reach for `alchemy-cli` instead.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add alchemyplatform/skills --skill alchemy-mcp -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/alchemy-mcp/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/alchemy-mcp/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add alchemyplatform/skills --skill alchemy-mcp -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/alchemy-mcp/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add alchemyplatform/skills --skill alchemy-mcp -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/alchemy-mcp/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install alchemyplatform/skills alchemy-mcp
```

2. **Manually: put the files in place**
- File: `.github/skills/alchemy-mcp/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add alchemyplatform/skills --skill alchemy-mcp -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/alchemyplatform/skills --path skills/alchemy-mcp
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/alchemy-mcp/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add alchemyplatform/skills --skill alchemy-mcp -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/alchemyplatform/skills/tree/HEAD/skills/alchemy-mcp/SKILL.md

## When to use it
- check a wallet balance right now
- pull NFT metadata for an owner
- preview what a transaction will change
- trace a failed call
- spin up an Alchemy app and set its allowlist

## Example prompts
- List my Alchemy apps and select the one for eth-mainnet
- What is the current price of the USDC token?
- Simulate the asset changes for this transaction

description: Use the Alchemy MCP server (`https://mcp.alchemy.com/mcp`) for live blockchain data and admin work when MCP is wired into your AI client and the Alchemy CLI is NOT installed locally. Exposes 159 tools across 100+ chains for token prices, NFT metadata, transactions, simulation, tracing, account abstraction, Solana DAS, and app management. Use for live querying, analysis, admin work, or on-machine agent work — not for application code that ships to production. For application code, use the `alchemy-api` skill (with API key) or `agentic-gateway` skill (without). When the CLI is also installed locally, prefer `alchemy-cli` instead.
license: MIT
compatibility: Requires an MCP-compatible AI client (Claude Code, Codex, Cursor, Claude Desktop, VS Code Copilot, etc.) configured against `https://mcp.alchemy.com/mcp`. OAuth flow handled by the client — no API key or local install required.

# Alchemy MCP

Use the hosted Alchemy MCP server for live blockchain data, transaction simulation, tracing, NFT/portfolio queries, and Alchemy app administration from inside your AI client.

## When to use this skill

Use `alchemy-mcp` when **all** of the following are true:

- The user wants **live agent work** — live querying, analysis, admin work, or on-machine automation that the agent runs now in this session
- An MCP-compatible client (Claude Code, Codex, Cursor, Claude Desktop, VS Code Copilot, etc.) is already wired against `https://mcp.alchemy.com/mcp`, OR the user is willing to add it
- The Alchemy CLI (`@alchemy/cli`) is **not** installed locally

If the CLI is installed locally — or if both CLI and MCP are available — prefer the `alchemy-cli` skill instead. The CLI is the preferred local fallback runtime path.

## When to use a different skill

| Situation | Use this skill instead |
| --- | --- |
| `@alchemy/cli` is installed locally, or both CLI and MCP are available | `alchemy-cli` |
| Neither CLI nor MCP is available | install `alchemy-cli` (`npm i -g @alchemy/cli`), then use `alchemy-cli` |
| Building application code that runs outside this agent session, with an Alchemy API key | `alchemy-api` |
| Building application code without an API key, or as an autonomous agent that needs to pay for itself, or you explicitly want x402/MPP | `agentic-gateway` |

Do **not** use this skill to write production application code — MCP tools are for live agent work, not for embedding into shipped software.

## Connect your client

The server runs at `https://mcp.alchemy.com/mcp` and authenticates via OAuth — your client opens a browser to sign in with your Alchemy account on first use. No API key or local install required.

### Claude Code

The fastest path is the official [Alchemy Claude Plugin](https://www.alchemy.com/docs/alchemy-claude-plugin), which bundles this MCP server, slash commands (`/alchemy:balance`, `/alchemy:nfts`, `/alchemy:portfolio`, etc.), and the Alchemy agent skills in one install:
