Mercury Parser MCP Server

What is Mercury Parser?

Mercury Parser fetches web pages with a headless Chromium (via Playwright) to capture JavaScript-rendered content, then uses the Mercury Parser to extract the article and returns it as Markdown. It follows pagination links automatically. Designed for AI agents like Claude to read and summarize articles.

How to use Mercury Parser?

The server exposes a single tool called extract which takes a URL and optional proxy argument. It can be used via Claude Desktop (local stdio) by adding the configuration to claude_desktop_config.json, or run over Streamable HTTP for remote access. It can also be tested via CLI with node extractContent.js <url> [proxy].
