What Web3 Research MCP can do in Cursor

create-research-plan

Creates a structured research plan for a token. Parameters: tokenName (full name of the token), tokenTicker (ticker symbol).

search

Performs a web search and returns the results. Parameters: query (search query), searchType (web, news, images, videos).

research-with-keywords

Searches for a token with specific keywords and saves the results. Parameters: tokenName, tokenTicker, keywords (array of keywords to search for).

update-status

Updates the status of a research section. Parameters: section (e.g. 'projectInfo', 'technicalFundamentals'), status (planned, in_progress, completed).

fetch-content

Fetches content from a URL and saves it as a resource. Parameters: url (URL to fetch), format (text, html, markdown, json).

list-resources

Lists all available resources that have been saved.

search-source

Searches for information about a token from a specific source. Parameters: tokenName, tokenTicker, source (e.g. 'CoinGecko', 'DeFiLlama', 'News').

coingecko-data

Fetches live market data directly from the CoinGecko public API — price, market cap, 24h/7d/30d changes, ATH/ATL, circulating supply, contract addresses across chains, and social/dev links. No API key required (free public tier, ~30 req/min); optionally set COINGECKO_API_KEY for the Pro API. Parameters: tokenName, tokenTicker.

Security

No API key required; runs fully local. An optional COINGECKO_API_KEY environment variable can be set to use a CoinGecko Pro API key, in which case requests are sent to the CoinGecko Pro API with the x-cg-pro-api-key header. Some websites block scraping, so direct content fetching may fail with 403 errors, and rate limits may apply to search operations.

Web3 Research MCP + Cursor FAQ

Where is the Cursor config file?

Cursor reads MCP servers from ~/.cursor/mcp.json. Paste the Web3 Research MCP config there under the "mcpServers" key and restart the client.

Is Web3 Research MCP safe to use with Cursor?

Does it require an API key?

No. It runs fully locally and uses free public API tiers. You can optionally set COINGECKO_API_KEY to use a CoinGecko Pro API key.

How do I install it?

Install automatically via Smithery with 'npx -y @smithery/cli install web3-research-mcp --client claude', or add the mcpServers config block manually to Claude Desktop or Cursor (command 'npx', args ['-y', 'web3-research-mcp@latest']).

What are the limitations?

Some websites block scraping, so direct content fetching may fail with 403 errors; it relies on search results that may not always be comprehensive; and rate limits may apply to search operations.
