Hubertino: Google Maps leads

Hubertino MCP server: Google Maps leads for Claude, Cursor and other AI agents

@hubertino/mcp-server connects any Model Context Protocol client (Claude Desktop, Claude Code, Cursor, VS Code, ...) to Hubertino, a Google Maps lead scraper. Ask your assistant for "dentists in Austin with emails". It starts a scrape, waits for it to finish, and gives you the leads as a table or as a CSV/XLSX file.

It wraps Hubertino's authenticated public REST API (docs) and uses your own API key and credits.

What you get

Each lead is one Google Maps business. Only fields that have a value are returned:

• Contact: name, category, phone, website, and an email found on the business's own website (enrichWebsite).
• Social profiles: Facebook, Instagram, LinkedIn, X, YouTube (enrichLinks).
• Location: address, city, state, postal code, country code, and a Google Maps link / place id.
• Reputation: rating, review count, business status.
• Extra fields (left out of compact results to save context): coordinates, opening hours, price range, service options, and order/reservation/menu links. Get them with get_results detail: "full", or in the download_export file.

Tools

Tool	What it does	API call
start_scrape	Starts a scrape for categories × locations. Uses credits.	POST /api/v1/scrapes
get_scrape	Returns status, progress, credits reserved and charged, and how many rows have an email, phone, etc.	GET /api/v1/scrapes/{id}
wait_for_scrape	Polls until the scrape is done or a timeout (default 50 s) passes. Sends progress notifications.	GET /api/v1/scrapes/{id}
list_scrapes	Lists your recent scrapes, optionally filtered by status.	GET /api/v1/scrapes
get_results	Returns lead rows as compact JSON, paged. Options: withEmailOnly, fields, detail.	GET /api/v1/scrapes/{id}/results
download_export	Saves a finished scrape as .xlsx or .csv on your computer.	GET /api/v1/scrapes/{id}/export

There is also one prompt, build_lead_list, which runs the whole workflow for a business type and area.

start_scrape takes the same inputs and limits as the API:

Input	Type	Notes
categories	string[]	Required. What to search for, e.g. ["dentist"]. 1–1,000 items, 1–120 characters each.
locations	string[]	Required. Cities, regions or zip codes. Include the country, e.g. "Austin, TX, United States". 1–10,000 items.
maxResults	integer	Required. Max places per search (per category × location pair), 1–500.
country	string	Optional Google edition code (us, gb, de, lt, ... 32 codes). If omitted, it is inferred from the locations.
enrichWebsite	boolean	Default true. Visits each business website to find an email. No extra credits.
enrichLinks	boolean	Default true. Collects social profiles and order/reservation links. No extra credits.

One scrape runs at most 2,000 searches (categories.length × locations.length).

Requirements

• Node.js 20 or newer (npx must be on the PATH your MCP client uses).
• A Hubertino account and an API key. New accounts get 100 free credits, and the API is included on every plan, including the free one.
  1. Sign up at hubertino.com.
  2. Open Settings (/dashboard/settings) and create an API key. It starts with hub_live_ and is shown only once, so copy it straight away.

Install

Every client needs the same thing: run npx -y @hubertino/mcp-server with HUBERTINO_API_KEY set in its environment. Replace hub_live_your_key_here with your key.

Claude Desktop

Open Settings → Developer → Edit Config. This opens claude_desktop_config.json, which lives at ~/Library/Application Support/Claude/claude_desktop_config.json on macOS and %APPDATA%\Claude\claude_desktop_config.json on Windows. Add:

{
  "mcpServers": {
    "hubertino": {
      "command": "npx",
      "args": ["-y", "@hubertino/mcp-server"],
      "env": {
        "HUBERTINO_API_KEY": "hub_live_your_key_here"
      }
    }
  }
}

Restart Claude Desktop. The Hubertino tools then show up in the tools menu.

A one-click bundle (hubertino-mcp.mcpb) can be built with npm run bundle and opened in Claude Desktop. It asks for the key in a form, so you don't edit any JSON.

Claude Code

claude mcp add hubertino -e HUBERTINO_API_KEY=hub_live_your_key_here -- npx -y @hubertino/mcp-server

Add --scope user to make it available in every project. Run claude mcp list to check that it's connected.

Cursor

Add the server to ~/.cursor/mcp.json (all projects) or to .cursor/mcp.json (one project):

{
  "mcpServers": {
    "hubertino": {
      "command": "npx",
      "args": ["-y", "@hubertino/mcp-server"],
      "env": {
        "HUBERTINO_API_KEY": "hub_live_your_key_here"
      }
    }
  }
}

VS Code (GitHub Copilot agent mode)

Add this to .vscode/mcp.json. VS Code prompts for the key and stores it securely:

{
  "inputs": [
    { "type": "promptString", "id": "hubertino-key", "description": "Hubertino API key (hub_live_...)", "password": true }
  ],
  "servers": {
    "hubertino": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "@hubertino/mcp-server"],
      "env": { "HUBERTINO_API_KEY": "${input:hubertino-key}" }
    }
  }
}

Other clients / from source

Any MCP client that can launch a stdio server works. To run from a checkout:

git clone https://github.com/hubertino-app/hubertino-mcp.git
cd hubertino-mcp && npm install && npm run build
# then point your client at:  node /absolute/path/to/hubertino-mcp/dist/index.js

Configuration

Variable	Required	Default	Purpose
HUBERTINO_API_KEY	yes	none	Your hub_live_... key. If it is missing, the server still starts and each tool explains how to set it.
HUBERTINO_API_URL	no	https://hubertino.com	API base URL. https://hubertino.com/api/v1 works too. Only https:// is accepted, except for localhost.
HUBERTINO_DOWNLOAD_DIR	no	~/Downloads, else the temp dir	Where download_export saves files.

Example prompts

• "Find dentists in Austin, TX with emails. 100 per search is enough."
• "Build a list of plumbers and electricians in Leeds and York, UK, then save it as a CSV."
• "Scrape roofing contractors in these zip codes: 78701, 78702, 78703. Show only the ones with an email and a website."
• "How is my last scrape doing?"
• "Show me page 2 of the results from my cafe scrape: name, phone and Instagram only."
• "Which of my finished scrapes had the most results? Download it as Excel."

A typical run looks like this:

start_scrape     {"categories":["dentist"],"locations":["Austin, TX, United States"],"maxResults":100}
  -> {"id":"6f1c…","status":"queued","credits":"Reserved 100 credits … the rest is refunded automatically.", …}
wait_for_scrape  {"scrapeId":"6f1c…"}
  -> {"status":"done","resultCount":…,"creditsCharged":…,"coverage":{"total":…,"email":…}, …}
get_results      {"scrapeId":"6f1c…","withEmailOnly":true,"limit":50}
  -> {"total":…,"returned":…,"hasMore":true,"nextOffset":50,"rows":[{"name":"…","phone":"…","email":"…"}, …]}
download_export  {"scrapeId":"6f1c…","format":"csv"}
  -> {"path":"/Users/you/Downloads/hubertino-6f1c….csv","bytes":…}

Credits, limits and errors

• 1 credit = 1 business delivered. When a scrape starts, Hubertino reserves categories × locations × maxResults credits, capped at your balance. When it finishes, you are charged only for rows actually delivered and the rest is refunded. If your balance is below the worst case, the scrape still runs but stops once the balance is used up. See pricing.
• Speed: a scrape takes minutes. Rows can be read while it runs (partial: true). Each row's _status goes found → extracted → enriched.
• Rate limit: 12 new scrapes per 5 minutes per account. Status, results and export calls are not rate limited.
• Page size: get_results reads up to 1,000 rows per call (default 50). To protect the model's context window, a page that would not fit in one tool response (about 50,000 characters) is cut short with trimmed: true; keep paging from nextOffset, ask for fewer columns with fields, or use download_export to get everything.
• Long scrapes: get_scrape and wait_for_scrape echo at most 25 categories/locations and add categoriesTotal / locationsTotal for longer lists. wait_for_scrape never runs more than about 8 s past its timeoutSeconds, even when the API answers slowly.
• Export: only available once status is done.

Errors come back as tool errors with a next step, so the assistant can recover or tell you what to do:

HTTP	Meaning	What the tool says
400	Invalid input	The API's message naming the bad field
401	Missing/invalid key	Check HUBERTINO_API_KEY; create or rotate one in Settings
402	Not enough credits	Nothing was charged; top up at /dashboard/billing
403	Refused (e.g. email not verified)	The API's message
404	Unknown scrape id	Check the id with list_scrapes
409	Not finished yet	Wait with wait_for_scrape, then retry
410	Results no longer stored	Start a new scrape
429	Rate limited	Wait a few minutes before starting another scrape
5xx	Temporarily unavailable	Retry in a minute
timeout / network	No answer from Hubertino	Retry shortly

If starting a scrape fails with a timeout, network error or 5xx, the scrape may still have been created. start_scrape then says to check list_scrapes before starting it again, so the same scrape is not run and charged twice.

Security and privacy

• Your API key stays in your MCP client's config and is sent only as a Bearer header to the Hubertino API over HTTPS. The server never logs it or returns it in a response. Don't paste your key into the chat.
• The server calls only the authenticated /api/v1 endpoints listed above. It makes no other network calls and does no scraping itself.
• download_export writes only hubertino-<scrape id prefix>.csv / .xlsx files into the chosen folder and never overwrites an existing file.
• Use lead data lawfully. Follow the privacy and anti-spam rules that apply to you and to the people you contact (for example GDPR, PECR, CAN-SPAM).
