MCP server for building lead lists: VOYGR Prospecting

#mcp #ai #sales #leadgen

If you build sales lists for local businesses, an AI agent can do most of the work: find the businesses, check they're still open, look up the owner and their email. To do that it needs tools. VOYGR Prospecting is an MCP server that gives Claude, ChatGPT, Codex or Cursor search over 16M+ US places, plus enrichment for each row.

What the agent can do with it

The server exposes places_* tools:

  • places_areas and places_categories resolve a city, ZIP or state and pick exact business categories
  • places_count and a five-place preview size the query, for free
  • places_find saves matching places as a list. places_upload_link takes your own CSV instead.
  • places_fill adds the columns you want: owners and key people with email and phone, open/closed status, hours, website, legal entity, or a custom question in plain English
  • places_check verifies names and addresses
  • places_export returns a CSV

Before any paid step, the agent tells you how many places and the maximum charge, and asks. For larger runs the server also returns a credit quote and waits for confirmation.

Install

Claude Code:

/plugin marketplace add voygr-tech/prospecting
/plugin install prospecting@prospecting
Enter fullscreen mode Exit fullscreen mode

Then run /mcp, select plugin:prospecting:places and sign in. No API key to copy.

claude.ai, Cowork, Claude Desktop: add a custom connector named VOYGR Prospecting with the URL https://api.voygr.tech/places/mcp, and sign in.

ChatGPT (web): Plugins, +, Create MCP App, server URL https://api.voygr.tech/places/mcp, OAuth. Custom apps depend on your ChatGPT plan.

Codex:

codex plugin marketplace add voygr-tech/prospecting
codex plugin add prospecting@prospecting
codex mcp login places
Enter fullscreen mode Exit fullscreen mode

Cursor, Windsurf and other MCP clients: point them at https://api.voygr.tech/places/mcp over streamable HTTP and sign in with OAuth.

Try it

Find 20 independent jewelers in Austin, TX. For each, get the owner's name and email and whether they sell lab-grown diamonds.

The agent resolves Austin and the jeweler category, counts and previews for free, quotes the cost, then builds the list and fills the three columns. You get a table in chat or a CSV.

Limits

Prospecting covers US places. Owner lookups can come back empty, and an empty result doesn't mean the business has no owner. A completed lookup can be charged even when it finds no answer; failed lookups are free. Lists go up to 10,000 places.

It also works with PlaceCall, our phone-call MCP server. Build a list here, then have your agent call the businesses on it to confirm details or ask a question.
