Overview

AI-generated overview

Lets an assistant search indexed B2B contacts, verify email deliverability, and check Leadloadz account usage quotas.

What you can do
Connects an AI assistant to the Leadloadz B2B lead generation platform over stdio. It exposes three tools: search_leads finds indexed B2B contacts by role, company, location, or technology using natural-language queries and returns leads with deliverability scores; verify_email checks an address in real time and returns a deliverability score and risk assessment; get_user_stats reads usage counters such as searches performed, emails verified, and remaining quota.
When to use it
Useful when an assistant needs to build or enrich prospect lists, look up contacts matching a target profile, or screen email addresses before outreach. Also handy for checking how much of a Leadloadz plan has been consumed.
Requirements
Runs locally as an npm package via npx or a global install, so Node.js is needed. Requires a Leadloadz account and an API key supplied through the LEADLOADZ_API_KEY environment variable; LEADLOADZ_API_BASE, LEADLOADZ_TIMEOUT_MS, and LEADLOADZ_DISABLE_TELEMETRY are optional. Network access to the Leadloadz API is required.
Before you install
The server sends queries and email addresses to the Leadloadz API, a third party, and searches consume account quota. The API key is a credential and should be kept out of shared configuration files. Anonymous telemetry is on by default and can be turned off with LEADLOADZ_DISABLE_TELEMETRY=1. The base URL must not use www, since redirects strip auth headers.

Installation

In SourceWeft

  1. Open Leadloadz in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

Score

50% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
