A powerful Model Context Protocol (MCP) server implementation for seamless Apollo.io API integration, enabling AI assistants to interact with Apollo.io data.

Overview

This MCP server provides a comprehensive set of tools for interacting with the Apollo.io API, allowing AI assistants to:

  • Enrich data for people and organizations
  • Search for people and organizations
  • Find job postings for specific organizations
  • Perform Apollo.io operations without leaving your AI assistant interface

Why Use This MCP Server?

  • Seamless AI Integration: Connect your AI assistants directly to Apollo.io data
  • Simplified API Operations: Perform common Apollo.io tasks through natural language commands
  • Real-time Data Access: Get up-to-date information from Apollo.io
  • Secure Authentication: Uses Apollo.io's secure API token authentication
  • Extensible Design: Easily add more Apollo.io API capabilities as needed

Installation

Questions

What is the Apollo.io MCP server?

apollo.io mcp server typescript

What tools does Apollo.io expose?

7 in total: 7 read-only, 0 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.

Is Apollo.io safe to connect to an agent?

The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.

What credentials does Apollo.io need?

It reads APOLLO_IO_API_KEY from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.

How does Apollo.io run?

It speaks stdio, so it runs as a local process your client starts. It is published on npm as apollo-io-mcp-server at 0.1.0.

How current is this page?

The grade is for one exact copy of the source (ceedf5e648ff), read on 2026-10-08. The repository is watched and re-audited when it changes.
