anysite-mcp

Your agent learns a website once, then keeps it as a tool.

A real Chrome, signed in as you, on your own computer.

claude mcp add anysite -- npx -y anysite-mcp

No API keys. No cloud browser. No extra LLM. Your logins never leave your machine.

What it is

anysite-mcp is an MCP server that drives a real Chrome on your computer. Every site gets its own browser profile that you sign in to once, by hand. The agent then works the site the way a screen reader does, by role and name, so small redesigns don't break it.

When the agent gets a job done, it can save the steps as a shortcut, and that shortcut becomes a new tool it can call in one step next time.

Your accounts, kept apart

One Chrome profile per site, signed in by hand once. Google sign-in works.

Gets faster with use

A job the agent has figured out becomes a one-call tool that's there next session. Shortcuts are tested before they're saved and fail loudly if a page stops looking right.

Repairs itself

When a site renames a button or swaps it for a link, the shortcut finds the new one and updates itself. No extra LLM needed.

Learns by watching

Run anysite-mcp record github.com my_job, do the job by hand, and it's a tool.

You set the limits

Per site: read-only, ask before sending, buying or deleting, and which domains it may open.

Light on tokens

After each action the agent sees only what changed, and points at elements by ref. web_extract turns lists and tables into JSON.

A shared, health-checked library

Community shortcuts are tested against the live sites every week, and you can search them from the terminal.

Packs for popular sites

Gemini and NotebookLM are included. A new pack is one file.

See it in action

You:    Ask Gemini to summarise this PDF, then add the summary as a source to my "Thesis" notebook in NotebookLM.

Claude: gemini_ask { prompt: "Summarise this PDF in 10 bullet points", files: ["~/Downloads/paper.pdf"] } → - The study compares … (Chat: https://gemini.google.com/app/…) notebooklm_add_source { notebook: "Thesis", text: "- The study compares …" } → Added pasted text.

You: Check my GitHub notifications.

Claude: web_open { site: "github.com", url: "/notifications" } → This looks like a sign-in page. Call web_login for "github.com" … web_login { site: "github.com" } "A Chrome window opened on GitHub. Sign in there, then quit that window and tell me." You: done Claude: web_open { site: "github.com", url: "/notifications" } → (accessibility tree of your inbox) web_save_shortcut { site: "github.com", name: "notifications", description: "List unread GitHub notifications", steps: [{ "action": "open", "url": "/notifications" }, { "action": "read", "role": "main" }] } → Saved github_com_notifications.

(Next week, in a new session) You: Anything new on GitHub? Claude: github_com_notifications {} → 3 unread: …

Why another browser MCP?

Most browser tools make the agent rediscover a site every session. anysite-mcp keeps what it learned.

[!NOTE]

Profiles are kept apart on purpose. Copying a signed-in profile so two browsers share one session gets that

session revoked by Google (and other careful sites), which logs you out everywhere.

Quick start

Requirements: Node 22+ and Chrome (or npx playwright install chromium). Works on macOS, Windows and Linux.

1. Sign in to the sites you want, once each. A normal Chrome window opens; sign in, then quit it (Cmd+Q on a Mac, close all its windows on Windows and Linux).

npx -y anysite-mcp login gemini

npx -y anysite-mcp login notebooklm npx -y anysite-mcp login github.com

2. Add the server to your agent.

Claude Code

claude mcp add anysite -- npx -y anysite-mcp

Claude Desktop, Cursor, Windsurf and other MCP clients

Add this to claude_desktop_config.json or the client's MCP settings:

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

3. Ask your agent to do something on one of those sites. That's it.

With no arguments the server offers every site you have signed in to. To pick sites, list them: npx -y anysite-mcp gemini github.com. The agent can also add a new site at any time by calling web_login.

anysite-mcp is listed in the MCP Registry as io.github.DwytMCL/anysite-mcp, so clients that browse the registry can find and install it.

Tools

Any site

Each tool takes site: a pack name like gemini, or a domain like github.com.

Every tool carries MCP annotations for clients that use them, for example to ask before a destructive tool runs. Tools that only read are marked read-only, and tools that can change something on a page (clicking, typing, choosing, pressing keys, uploading) are marked destructive. Shortcut tools are marked by what their steps do.

Packs included

Shortcuts

A shortcut is a list of steps, each one the arguments of a web_* tool plus its action. {{param}} is filled in from the tool's arguments, and the shortcut returns the text of its read steps.

• A step's expect is text that must be on the page afterwards, so a shortcut fails instead of returning the wrong thing.
• Before saving, the steps are run once with test_args (set verify: false for steps that must not happen twice, like sending).
• Shortcuts are saved in ~/.anysite-mcp/sites/ .json, which you can edit, share or commit.

{

"search": { "description": "Search Hacker News and return the results", "params": { "query": "What to search for" }, "steps": [ { "action": "open", "url": "https://hn.algolia.com/?q={{query}}" }, { "action": "wait", "seconds": 5, "until_text": "results", "expect": "{{query}}" }, { "action": "read", "role": "main" } ] } }

Params can also be { "description", "type": "number" | "boolean", "optional", "default" }.

When a site changes

A step whose element is gone is repaired before it fails:

1. First with other ways to find it that were noted when the shortcut was saved (its label, its text).
2. Then with the closest element of a similar role on the page. "Search products" finds "Product search"; a button that became a link is still found.

Only a single clear match counts. The shortcut file is updated and the agent is told what changed. If nothing fits, the error says which step and why, and the agent can redo the job and save the shortcut again.

Record a shortcut by doing the job yourself

npx -y anysite-mcp record github.com star_repo

Chrome opens on the site; click and type as usual, then press Enter in the terminal. Each typed value becomes a parameter, with what you typed as its default. The agent can do the same with web_record.

Check your shortcuts

npx -y anysite-mcp doctor

doctor follows each shortcut while its steps only open and read pages, checks that the element of the first step that would act is there, and repairs what it can. It never clicks or types.

Each parameter gets its default if it has one. Otherwise an optional parameter is left empty, so the check sees the p
