Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

alchemy-mcp-server CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Commands

Development

  • pnpm install - Install dependencies
  • pnpm build - Build TypeScript to dist/ directory
  • pnpm watch - Watch mode for development
  • pnpm inspector - Launch MCP Inspector for debugging tools
  • node --test tests/*.test.ts --loader=tsx/esm - Run tests

Build System

  • Uses TypeScript with ES modules ("type": "module")
  • Outputs to dist/ directory
  • Entry point: dist/index.js
  • Build process includes shx chmod +x dist/*.js for executable permissions

Architecture

This is an MCP (Model Context Protocol) server that provides blockchain data access through Alchemy APIs. The codebase follows a modular structure:

Core Components:

  • index.ts - Main MCP server with tool definitions using Zod schemas
  • api/alchemyApi.ts - Core API client with blockchain data fetching logic
  • api/alchemyClients.ts - HTTP client creation for different Alchemy services
  • libs/uniswap/ - Uniswap SDK integration for DEX functionality
  • utils/ - Utility functions for data conversion and date handling

MCP Tool Categories:

  1. Prices API - Token price queries by symbol/address, historical data
  2. MultiChain Token API - Token balances across multiple networks
  3. Transaction History API - Wallet transaction data with pagination
  4. Transfers API - Asset transfer queries with filtering
  5. NFT API - NFT ownership and contract data
  6. Wallet API - Transaction sending via Smart Contract Accounts
  7. Swap API - DEX trading functionality

Key Dependencies:

  • @modelcontextprotocol/sdk - MCP server framework
  • @uniswap/v3-sdk and related packages - DEX integration
  • @aa-sdk/core - Account Abstraction for wallet operations
  • viem and ethers - Ethereum interaction libraries
  • zod - Schema validation for tool parameters

Environment Setup:

  • Requires ALCHEMY_API_KEY environment variable
  • Uses .cursor/mcp.json for local MCP server configuration
  • Supports multiple blockchain networks (Ethereum, Base, etc.)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
