Overview

AI-generated overview

Local MCP server that connects an AI assistant to the Apollo.io sales platform for prospecting, contact enrichment, CRM records and email sequences.

What you can do
  • Search and enrich people and companies in Apollo's contact database, including verified emails and phone numbers
  • Create, update, search and delete CRM contacts, accounts, deals, tasks and notes
  • Manage email sequences and outreach: add contacts, pause or remove them, review sent emails and open/click activity
  • Organize records with labels, pipeline stages, custom fields, team member lookup and activity logs
  • Check API credit usage and API health, and search recent news about target companies
When to use it
Useful for sales, recruiting or go-to-market work where you want an assistant to prospect, enrich leads and keep Apollo CRM records and outreach sequences up to date from the editor or chat client.
Requirements
Node.js 18 or later, with the server cloned and built locally (npm install, npm run build) and launched as a local stdio process. An Apollo.io API key supplied through the APOLLO_API_KEY environment variable, plus an MCP-compatible client such as Claude Code or Cursor. Network access to the Apollo.io API.
Before you install
The Apollo.io API key is a billable account credential; store it only in the client's environment configuration. Many enrichment and search tools consume Apollo credits, so assistant-driven calls can spend money on your plan. Tools can create, update and permanently delete CRM contacts, notes, labels and deals, and can add contacts to or remove them from live email sequences, which may send outreach. Contact and company data is sent to Apollo.io.

Installation

In SourceWeft

  1. Open Apollo.io MCP Server 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.
