@page2ai/mcp — Web to Markdown for LLM Context

No downloads badge on purpose: npm download counts are dominated by registry mirrors and bots, and this README only shows numbers a human can trust.

One-click webpage-to-Markdown MCP server for ChatGPT, Claude, and Gemini. Preserves code blocks with language hints, tables, and reading structure. Fetch, extract, convert — one tool, one command, entirely on your machine. No API key, no account, no telemetry; the only network requests are to the URLs you pass it.

Companion to the Page2AI Chrome & Firefox extensions, which convert the live page in your own browser with their own pipeline. This server is built on @page2ai/core.

Quick start

npx -y page2ai-mcp

This starts the stdio MCP server — it waits silently for a client, so wire it into one of the clients below rather than running it bare. Requires Node.js 20+. No API key. If npx ever serves you a stale cached version, run npx -y page2ai-mcp@latest once.

Updating. npx -y page2ai-mcp asks npm for the newest version each time the server starts, but an MCP client keeps the server running until you quit it: quitting and reopening the client is the update. A version named in the config ([email protected]) stays until you change it. npx -y page2ai-mcp --version prints the version npx runs now.

page2ai-mcp is a thin unscoped wrapper around @page2ai/mcp, released together with it; its dependency is a ^ range, which on 0.x versions admits patch releases only.

Hosted endpoint (beta) — no install at all

For clients that only accept a remote MCP server URL (Streamable HTTP):

https://page2ai-mcp-remote.vercel.app/api/mcp

Same tool, same code (see remote/), rate-limited per IP. Privacy trade-off: URLs sent to the hosted endpoint are fetched from that server, so they transit infrastructure operated by the author (on Vercel). Running locally via npx keeps everything on your machine — prefer it when you can.

Claude Code

claude mcp add page2ai -- npx -y page2ai-mcp

Claude Desktop

One-click bundle: download page2ai-mcp-<version>.mcpb from the latest release, then in Claude Desktop open Settings → Extensions → Advanced settings → Install Extension… and pick the file.

Or add to claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then fully quit and restart Claude Desktop:

{
  "mcpServers": {
    "page2ai": { "command": "npx", "args": ["-y", "page2ai-mcp"] }
  }
}

Cursor

Or add to ~/.cursor/mcp.json (global) / .cursor/mcp.json (project):

{
  "mcpServers": {
    "page2ai": { "command": "npx", "args": ["-y", "page2ai-mcp"] }
  }
}

VS Code (GitHub Copilot)

code --add-mcp '{"name":"page2ai","command":"npx","args":["-y","page2ai-mcp"]}'

Or add to .vscode/mcp.json:

{
  "servers": {
    "page2ai": { "type": "stdio", "command": "npx", "args": ["-y", "page2ai-mcp"] }
  }
}

Codex CLI

codex mcp add page2ai -- npx -y page2ai-mcp

Gemini CLI

gemini mcp add page2ai npx -y page2ai-mcp

Antigravity

agy mcp add page2ai npx -y page2ai-mcp

Windsurf

Add to ~/.codeium/windsurf/mcp_config.json (macOS/Linux) or %USERPROFILE%\.codeium\windsurf\mcp_config.json (Windows):

{
  "mcpServers": {
    "page2ai": { "command": "npx", "args": ["-y", "page2ai-mcp"] }
  }
}

Zed

Add to settings.json (zed: open settings file):

{
  "context_servers": {
    "page2ai": { "command": "npx", "args": ["-y", "page2ai-mcp"] }
  }
}

Other MCP clients

Any client that speaks MCP over stdio works — Cline, Continue, JetBrains AI Assistant, LM Studio and others. Point their MCP server settings at the same command: npx -y page2ai-mcp.

Letting an AI agent install it

If an AI agent (Cline, Claude Code, Codex, …) is doing the setup for you, point it at llms-install.md — a machine-oriented install guide with the exact command per client and a verification step.

Tools

Tool	Description	Read-only	Example
page_to_markdown	Fetch a web page URL, or take its HTML, and convert to clean Markdown	✅	page_to_markdown(url="https://docs.anthropic.com/en/api/messages")

Pages behind a sign-in or rendered by JavaScript

The server fetches without cookies and runs no page scripts. For a page that needs either:

• Pass the HTML you already have (from Playwright, Chrome DevTools MCP or another browser tool) as html, with the page's url: the HTML is converted, the URL is never fetched, and relative links resolve against it. The frontmatter then carries provenance: "HTML supplied by the caller; the source URL was not fetched". An empty html is an error, not a fetch of url.

• Or turn on Agent Bridge in the Page2AI extension (1.6.0 or later): popup → Agent Bridge switch → allow access to websites. While the extension is connected, url pages open in a background tab of your own browser, with its cookies and scripts, and come back as the extension's Markdown (the call's include_images and include_frontmatter are honoured there, not the popup's). The extension refuses sign-in providers' pages and anything that is not http(s); a page it refuses is fetched by the server as usual, with a second text block saying why; when the browser ends on another page (a sign-in redirect), a second text block names the page it got. Private, loopback and cloud metadata addresses are refused before the browser opens them, as by the server's own fetch, and so is a page the browser was redirected to at one. The bridge listens on ws://127.0.0.1:3025 only.

  The key (0.6.0 and later). The bridge works only with the key the extension shows: popup → Agent Bridge on → Copy key. Give it to this server as PAGE2AI_BRIDGE_KEY: in Claude Desktop (the .mcpb extension) paste it into Page2AI's setting Agent Bridge key; in a JSON config add "env": { "PAGE2AI_BRIDGE_KEY": "<key>" } to the server entry; with Claude Code, claude mcp add page2ai -e PAGE2AI_BRIDGE_KEY=<key> -- npx -y page2ai-mcp. Restart the MCP client after. Several browsers or profiles: put their keys in the one variable, separated by commas; the first to connect holds the bridge. Several MCP clients running Page2AI (Claude Desktop and Cursor, say): the one started first holds port 3025 and the others run without the bridge, so give the key to each of them. Without a key the server never sends a page to a browser, and the popup and this server's log say what to paste where. On every connection both sides prove they know the key (an HMAC exchange; the key never crosses the socket), the server first: a program that took port 3025 while no server ran gets nothing from the extension, and a program that connects to the server without the key cannot ask it for pages. Firefox needs no extra setting since 0.6.0 (0.5.3 required the install's UUID in PAGE2AI_BRIDGE_ORIGINS). New key in the popup, or reinstalling the extension, makes a new key: replace the old one with it. Whoever reads your MCP client's config or the browser profile can read the key: the bridge is no stronger than your user account.

Example prompts

1. Fetch documentation and answer questions:

"Use page_to_markdown to fetch https://docs.anthropic.com/en/docs/build-with-claude/extended-thinking and summarize the three main use cases for extended thinking."

2. Extract API reference into a code snippet:

"Fetch https://ai.google.dev/gemini-api/docs/thinking with page_to_markdown, then generate a Python code sample using the thinking budget parameter."

3. Compare two documentation pages:

"Fetch both https://docs.anthropic.com/en/docs/prompt-engineering and https://platform.openai.com/docs/guides/prompt-engineering with page_to_markdown, then summarize the differences in approach."

# Messages



A beta version of this API exists and may have additional functionality. [View the beta version](https://platform.claude.com/docs/en/api/http/beta/messages).

1. [API reference](https://platform.claude.com/docs/en/api/http)

##### [Create a Message](https://platform.claude.com/docs/en/api/http/messages/create)

 POST /v1/messages

Send a structured list of input messages with text and/or image content, and the model will generate the next message in the conversation.

YAML front matter (title, source, capture timestamp, page metadata, extractor provenance), then the page as Markdown: headings, tables and fenced code preserved; navigation, header, footer and sidebars dropped. Interface buttons are left out (core 0.2.1); up to 0.3.0 this page also printed «Copy page» (with the glyph of its icon) and the «cURL» code-sample switcher, each twice. Up to 0.2.8 this URL returned the site's own Markdown copy (extractor_source: "content-negotiation"); since 0.3.0 the server reads only the page.

Configuration

No setup required — every argument has a sensible default. page_to_markdown accepts:

Argument	Type	Default	Effect
url	string	—	Absolute http(s) URL to convert. Private ranges, loopback and cloud metadata endpoints are blocked (SSRF guard). With html, not fetched: the base for relative links
html	string (≤ 10 MB)	—	The page's HTML, converted instead of a fetch. url or html is required
include_images	boolean	true	Keep  image references in the output
include_frontmatter	boolean	true	Prepend the YAML front matter block
timeout_ms	integer	15000	Abort the fetch after N ms (1000–60000)

The hosted endpoint takes url only (the contract its ChatGPT plugin was reviewed with) and caps timeout_ms at 20000.

Environment variables of the local server, all optional:

Variable	Default	Effect
PAGE2AI_BRIDGE_KEY	—	The Agent Bridge key(s) from the Page2AI popup, comma-separated. Without one the bridge connects no browser
PAGE2AI_BRIDGE_PORT	3025	Port of the Agent Bridge on 127.0.0.1. The extension connects to 3025 only, so change it for tests, not for a browser. If it is taken (another running instance), the server starts without the bridge
PAGE2AI_BRIDGE_ORIGINS	—	Exact origins of unpacked or self-built Chrome builds the bridge accepts besides Page2AI's Web Store ID, comma-separated (chrome-extension://<id>). Firefox needs none

Planned: a profile argument (auto | docs | marketing | research | dashboard | wordpress-marketing).

Privacy

@page2ai/mcp collects no data, sends no telemetry, and makes no external network calls beyond the URLs you explicitly provide. Note that your AI client (Claude, ChatGPT, …) still sends the extracted Markdown to its own model provider under that client's privacy policy — that part is outside this server's control. See PRIVACY.md for details.

With Agent Bridge on, the extension sends this server the URL's Markdown as your browser renders it, signed-in content included, over a WebSocket on 127.0.0.1; nothing else leaves the machine, but the Markdown then goes to your AI client like any other result.

The optional hosted endpoint is different by nature: URLs you ask it to convert are fetched from a server operated by the author (deployed on Vercel), and Vercel keeps its standard operational logs. No accounts, no tracking. If that trade-off matters for your use case, run the server locally — it is the same code.

Protocol revisions

Since 0.2.0 this server answers both MCP protocol revisions on the same stdio connection:

Revision	How a client opens the connection	Served
2026-07-28	server/discover, carrying io.modelcontextprotocol/protocolVersion in _meta	yes
2025-11-25 and earlier	the initialize handshake	yes

serveStdio picks the era from the opening message and pins one server instance for the life of the connection, so clients on older SDKs are unaffected. Note that a message carrying no version claim is treated by the specification as a 2025-era opening; server/discover without that _meta field is therefore answered with -32601 rather than being upgraded.

Verify against a build with the raw JSON-RPC frames, without a client library:

printf '%s\n' '{"jsonrpc":"2.0","id":1,"method":"server/discover","params":{"_meta":{"io.modelcontextprotocol/protocolVersion":"2026-07-28"}}}' | node dist/index.js

Known advisories

None. Moving to the v2 SDK removed 90 transitive packages (117 production dependencies down to 26) and with them the @hono/node-server advisory that 0.1.x carried through the monolithic @modelcontextprotocol/sdk; that package pulled the HTTP and OAuth server stack even for a stdio-only server. npm audit is clean as of 0.2.0.

Development

git clone https://github.com/igorsaevets/page2ai-mcp
cd page2ai-mcp
npm install
npm run build
node dist/index.js  # runs stdio MCP server

Test with MCP Inspector:

npx @modelcontextprotocol/inspector node dist/index.js

Build provenance

An MCP server runs with the privileges of whatever launched it, so where the tarball came from is a security question, not a formality. Releases from v0.1.2 onward are published from GitHub Actions with npm provenance: each version carries a Sigstore attestation naming the commit and workflow run that produced it, recorded in the public Rekor transparency ledger and shown as a badge on npmjs.com.
