Apollo MCP — Auth Setup

Apollo uses an API key to authenticate requests to its sales intelligence and engagement platform.

1. Get your credentials

  1. Open the Apollo Developer Portal (opens Apollo — we never see your key)
  2. Sign in and navigate to API Keys in your account settings
  3. Copy your existing API key or generate a new one

2. Set environment variables

macOS / Linux — add to ~/.zshrc or ~/.bashrc:

export APOLLO_API_KEY=YOUR_API_KEY_HERE

Then run source ~/.zshrc (or open a new terminal).

Windows — run in Command Prompt (then restart):

setx APOLLO_API_KEY "YOUR_API_KEY_HERE"

3. Verify

npx claude-skills doctor

You should see ✅ next to the Apollo MCP entry. If you see ❌, confirm the key is set: echo $APOLLO_API_KEY.

4. Restart Claude Code

Quit and reopen Claude Code (or run /mcp list inside Claude Code to confirm the Apollo MCP appears).
