Apollo.io MCP

Apollo is a big B2B contact database with built-in cold email. Its official connector lets Claude do the prospecting: "find marketing managers at Melbourne companies with 50 to 200 staff that are hiring" or "enrich this list and add them to my agency sequence".

It's in Claude's connector directory, so on the web or desktop you add it under Settings > Connectors. In Claude Code, run the command below, then type /mcp to sign in. Apollo also has a Claude Code plugin with ready-made prospecting workflows.

Enriching contacts uses your Apollo credits, and phone numbers cost extra. Adding people to a sequence can start sending emails, so check before you confirm. Apollo also asks you to turn off model training in your Claude settings before you connect.

• Search Apollo's database for people by job title, seniority and location
• Find companies by industry, size, tech used, funding or hiring
• Add work emails, phone numbers and company details to your contacts
• Save leads to lists, deals and tasks
• Draft email sequences and add contacts to them once you confirm

Open your terminal (the text window where you run Claude Code) in your project folder, then paste this command to connect it:

claude mcp add --transport http apollo https://mcp.apollo.io/mcp

The first time you use it, you'll be asked to sign in or paste an API key (a private code from the app that lets Claude use your account).
