Summary

Alchemy's official remote MCP server: 168 tools for onchain data across 100+ chains — balances, NFTs, prices, portfolios, transaction simulation and execution traces.

Features

  • 168 tools across Admin, RPC and Data categories
  • 100+ chains including Ethereum, Base, Polygon, Arbitrum, Optimism and Solana
  • Transaction simulation with asset-change previews, plus debug_* and trace_* execution traces
  • NFT ownership, floor prices, spam detection and rarity; token prices and multi-chain portfolios
  • Remote-only at mcp.alchemy.com/mcp with OAuth 2.1 + PKCE — no API key, no local install

Installation

Set up this MCP server in your favorite AI agent — copy a ready-made configuration below.

Any MCP-compatible agent

Most agents (Claude, Cursor, Windsurf, VS Code, and more) read a standard mcpServers configuration.

  1. Open your agent's MCP configuration file.
  2. Merge the snippet below into it.
  3. Restart the agent — the "Alchemy" tools will be available.

Description

Alchemy runs blockchain RPC and data infrastructure, and its official MCP server exposes that whole surface to an agent as 168 tools with no API key and no local install.

They fall into three groups. RPC (132 tools) covers standard EVM JSON-RPC for blocks, transactions, balances, gas and state, plus the Token API for ERC-20 balances, metadata, allowances and transfer history, transaction simulation with asset-change previews, debug_* and trace_* execution traces, ERC-4337 account-abstraction bundler and gas-manager calls, and Solana's Digital Asset Standard for NFTs and compressed NFTs. Data (28 tools) adds NFT ownership, collection metadata, floor prices, spam detection and rarity, current and historical token prices by symbol or contract, and multi-chain portfolio queries. Admin (8 tools) handles app and account management, webhook configuration and chain listing.

Coverage is 100+ networks — Ethereum, Base, Polygon, Arbitrum, Optimism, Solana, Starknet, zkSync, Scroll, Linea and the rest — with a list_chains tool so an agent can enumerate them rather than guess a chain ID.

Connection is a single remote URL, https://mcp.alchemy.com/mcp, authenticated with OAuth 2.1 and PKCE against your Alchemy dashboard account: the client opens a browser, you approve, and no secret is written to a config file. It works with Claude Code, Claude Desktop, Cursor, VS Code Copilot and Codex. For agents doing onchain analysis, the simulation and tracing tools are the ones that change what is possible — an agent can preview what a transaction would do before recommending it, rather than reasoning about bytecode.
