Overview

AI-generated overview

Hollerdex is a remote Apify-hosted MCP server that turns a domain into a ranked contact card of public emails, phone numbers and social profiles.

What you can do
Look up a website domain and get back its publicly available contact details in one ranked card. The results cover email addresses, phone numbers and social media profiles. Contacts are ranked so the assistant can point to the most relevant ones first. Runs are executed on Apify and billed per result.
When to use it
Useful when you need to find contact information for a company or website, such as for outreach, lead research or verifying who to reach at a domain, without collecting the details by hand.
Requirements
A remote MCP endpoint at mcp.apify.com reached over streamable HTTP. An Apify account and an Apify API token are required, sent in the Authorization header as a Bearer token. OAuth authentication is declared. Network access to Apify is needed.
Before you install
The Authorization header carries your Apify API token, a secret that grants access to your Apify account. Runs are billed per result to that account, so lookups cost money. The server returns third-party contact data collected from public sources; handle it with care for privacy and applicable rules on contacting people.

Installation

In SourceWeft

  1. Open Hollerdex: Website Contact Finder (Emails, Phones & Socials) in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.CyberMax-tools%2Fwebsite-contacts/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.
