How to Set Up and Use Web3 Research
Web3 Research MCP is a free, fully local server that brings structured cryptocurrency research into any MCP-compatible AI client. It aggregates live market data from CoinGecko and protocol metrics from DeFiLlama, performs targeted web searches, and stores fetched content locally so you can build comprehensive token reports without paying for a premium research platform. It is well-suited for analysts, traders, and developers who want AI-assisted due diligence on crypto assets using open data sources.
Prerequisites
- Node.js v16 or higher installed
- An MCP client such as Claude Desktop or Cursor
- Optional: CoinGecko Pro API key (COINGECKO_API_KEY) to unlock higher rate limits and Pro endpoints
Add the server to your MCP client config
No separate installation step is needed — npx pulls the package on first run. Open your Claude Desktop config file and add the server block.
# macOS config location
~/Library/Application Support/Claude/claude_desktop_config.json
# Windows config location
%APPDATA%\Claude\claude_desktop_config.jsonConfigure the server block
Add the web3-research-mcp entry. If you have a CoinGecko Pro key, include it in the env section; otherwise omit the env block and the server will use the free public API.
{
"mcpServers": {
"web3-research-mcp": {
"command": "npx",
"args": ["-y", "web3-research-mcp@latest"],
"env": {
"COINGECKO_API_KEY": "your-coingecko-pro-key"
}
}
}
}Restart your MCP client
Save the config file and fully restart Claude Desktop or Cursor. The server will be downloaded on first use and should appear as connected in the client's MCP panel.
Start a research session
Use the 'token-research' built-in prompt or ask naturally about any token. The server will create a research plan, gather data from multiple sources, and compile results.

Natural-language queries you can send once the server is connected.
- "Research the ARB token: get current price, market cap, and list all exchanges trading it"
- "Find the top DeFi protocols by TVL and compare their fee revenue for this week"
- "Search for recent news about the Uniswap v4 launch and save the content locally"
- "What is the contract address for MATIC on Ethereum, and what is its current supply?"
- "List all resources you've saved from this research session"Troubleshooting Web3 Research
CoinGecko requests fail or return 429 rate-limit errors
The free CoinGecko API has low rate limits. Set COINGECKO_API_KEY to a Pro key in the env block to route requests through the authenticated Pro API endpoint with higher limits.
npx fails to download the package on first run
Check your internet connection and ensure npx is available (`npx --version`). If behind a corporate proxy, set the HTTP_PROXY and HTTPS_PROXY environment variables before starting Claude Desktop.
Web searches return no results
The search tool performs public web searches; transient outages or unusual network configurations can block it. Try rephrasing your query or using the coingecko-search or defillama-search tools directly for on-chain data.
