Common questions
Is PublicWWW safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (1.2.0) reached the registry 25 days ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
What can I use instead?
In the same category: Context7, Codebase Memory, Exa

PublicWWW MCP server
Search the source code (HTML, JavaScript, CSS) of hundreds of millions of websites from an AI assistant: which sites load a script, use a library, carry a tracking id or a widget - then save them as a cluster and pull contacts, social profiles or tag ids out of their pages. PublicWWW runs a remote MCP server:
https://api.publicwww.com/mcpEleven tools: search (query, rows, page, snippets), account (plan, searches and extraction points left today), read_docs (PublicWWW's own documentation and price list in Markdown) and eight for clusters. The same documentation pages are MCP resources, publicwww://docs/ . Without signing in, the tool list and read_docs work; the other tools need a paid plan, and a free account gets plan_required from them - see limits.
Sign in
- OAuth - Claude, ChatGPT and Claude Code send you to PublicWWW to press Allow. Nothing to copy.
- A token - other clients send
Authorization: Bearer. Issue one on your profile page and keep it in thePUBLICWWW_TOKENenvironment variable.
Install
| Client | How |
|---|---|
| Claude (web, desktop) | Customize → Connectors → Add custom connector, URL above - guide |
| ChatGPT | Plugins → Add → Add custom MCP server, OAuth - guide |
| Claude Code | the plugin below, or claude mcp add --transport http publicwww https://api.publicwww.com/mcp |
| Cursor | |
| VS Code | |
| Gemini CLI | gemini extensions install https://github.com/publicwww-com/publicwww-mcp |
| Codex CLI | codex mcp add publicwww --url https://api.publicwww.com/mcp --bearer-token-env-var PUBLICWWW_TOKEN |
| opencode | clients/opencode.json |
| Goose | clients/goose.config.yaml |
| DeepSeek Harness | dsh plugin --profile add github:publicwww-com/dsh-publicwww - plugin |
| Anything else | a config file from clients/ |
The Cursor button reads the token from PUBLICWWW_TOKEN; VS Code asks for it once and keeps it in its secret storage.
Claude Code plugin
The MCP server (sign in with OAuth) and a skill that teaches the query syntax:
/plugin marketplace add publicwww-com/publicwww-mcp/plugin install publicwww@publicwww
Then run /mcp, pick publicwww and choose Authenticate.
Gemini CLI extension
gemini extensions install https://github.com/publicwww-com/publicwww-mcpIt asks for the token once and keeps it in the system keychain.
Agent skill
skills/publicwww-search is a skill in the open Agent Skills format: how to write PublicWWW queries and use the tools. Copy the folder into your agent's skills directory (for example .agents/skills/ or ~/.claude/skills/).
Query syntax, briefly
| Query | Finds | |
|---|---|---|
"angular.min.js" | that exact text in the page source | |
bootstrap jquery | both, anywhere on the page | |
| `jquery (slick \ | swiper)` | jquery and either of the two |
"amcharts.js" -bootstrap | the first without the second | |
site:de bootstrap | only .de sites | |
depth:all "math.min.js" | inner pages too, not only home pages |
More: query syntax.
Clusters
A cluster is a saved list of websites the assistant can build, combine and extract data from.
| Tool | What it does |
|---|---|
list_clusters | the account's clusters, newest first |
get_cluster | a page of the domains in a cluster |
create_cluster | from a search (query, costs one search) or a list of domains |
combine_clusters | and, or, or diff (in the first, not in the second) of clusters |
extract_from_cluster | values from the page source of every site: ready-made presets or your own regex, part after part |
rename_cluster | a new name |
delete_cluster | deletes for good; marked destructive, so the assistant asks you first |
Presets: email, phone, whatsapp, telegram, viber, line, facebook, instagram, x, linkedin, youtube, tiktok, pinterest, threads, bluesky, discord, github, google_play, app_store. Anything else is a regular expression in slashes whose first group is the value, e.g. /data-site-id="([0-9]+)"/i. Extraction spends the day's extraction points; an account keeps up to 100 clusters.
Ask in plain words: *"Find sites that load static.hotjar.com, save them as a cluster and get their contact emails and phones"* - the assistant runs create_cluster, then extract_from_cluster with the email and phone presets until the cluster is done. More: tools.
Calling it directly
examples/mcp-curl.sh lists the tools, reads the account and runs a search with plain curl. Streamable HTTP, JSON answers, no sessions - see for developers.
For scripts the REST API is the simpler road - the same search, clusters and token, with CSV and NDJSON. Small clients: Python, JavaScript, PHP, Go, Ruby.
