web-fetch-mcp — Claude Code MCP server: what it does, setup
This MCP server lets an agent read web pages, summarize them, compare URLs, and pull out requested details.
claude mcp add --env GEMINI_API_KEY=<GEMINI_API_KEY> --env HTTP_PROXY=<HTTP_PROXY> --env HTTPS_PROXY=<HTTPS_PROXY> --transport stdio web-fetch-mcp -- npx -y web-fetch-mcpWhat web-fetch-mcp does
web-fetch-mcp exposes three tools for web research: summarize_web creates a short account of linked pages, compare_web checks information across URLs, and extract_web finds requested details from page content. A single request can include up to 20 URLs. HTML is converted into readable text, and GitHub /blob/ links are resolved to raw content.
The server runs through npx and connects over MCP. It requires GEMINI_API_KEY; HTTP_PROXY and HTTPS_PROXY can be supplied when the route to Gemini needs a proxy. Without GEMINI_API_KEY, the server will not start. Requests to private IP addresses are blocked, while timeout and content-size limits can be configured.
What it helps with
- summarize research pages by URL
- compare claims across several sites
- extract named details from web content
- process up to 20 URLs in one request
Example prompts for the agent
- Use
summarize_webto give me the main points from these URLs: ... - Call
compare_weband contrast the pricing and terms on these pages: ... - Use
extract_webto find publication dates and author names in these pages: ...
