Apollo MCP Server Documentation

Getting Started

1. Connect Apollo - Open Claude, go to Settings > Connectors, and click Connect next to Apollo. You'll be redirected to Apollo to authorize access via OAuth. No API keys needed.
2. Authorize permissions - Review the requested scopes and click Allow. Claude will be able to search for prospects, get latest information (firmographics and demographics), manage contacts and sequences on your behalf using your Apollo account's permissions.
3. Start using Apollo - In any Claude conversation, enable the Apollo connector via the + button. Then ask Claude anything - like "Find senior engineers at fintech companies in New York" - and Apollo's tools activate automatically.

Works with any Apollo plan. Your existing plan's API limits and credit balance apply.

What You Can Do

Search & Prospecting

Find people, companies, contacts, and sequences across Apollo's database using natural language.

• Search People - Search Apollo's 275M+ person database by title, seniority, location, company, industry, employee count, revenue, tech stack, and more. Returns names, titles, companies, and data availability flags (email, phone, location).
• Search Companies - Find companies by domain, location, size, revenue range, industry, or keywords. Returns firmographic profiles.
• Search Contacts - Search your team's saved contacts in Apollo by name, stage, or keywords.
• Search Sequences - Find existing email sequences in your account by name or keywords.

Note: People search results show names and titles but do not include email addresses or phone numbers. Use the enrichment tools below to reveal contact details.

Enrichment

Unlock verified emails, direct dials, and full profiles using Apollo's enrichment engine. Enrichment consumes credits based on your plan.

• Enrich Person - Provide a name, email, LinkedIn URL, or domain to get verified email, phone numbers, current title, company, employment history, and more.
• Enrich Company - Provide a domain or company name to get full firmographics: industry, employee count, revenue, tech stack, funding history, headquarters, and more.
• Bulk Enrich People - Enrich multiple people in a single request. Provide an array of identifying details (name + domain, LinkedIn URLs, emails) and get back enriched profiles for each.

Contact Management

Create and update contacts in your Apollo CRM directly from Claude.

• Create Contact - Add a new contact with name, email, title, company, phone numbers, address, custom fields, and list assignments. Optionally enable deduplication to prevent duplicates.
• Update Contact - Modify any field on an existing contact: title, company, email, phone numbers, custom fields, and more.
• Get Contact - Retrieve full details for a specific contact by their Apollo ID.

Company Management

• Get Company - Retrieve full firmographic details for a specific company by their Apollo ID.
• Get Job Postings - Search for open job postings associated with companies in Apollo. Useful for identifying hiring signals and expansion intent.

Sales Engagement / Sequences

Manage your outbound sequences without leaving Claude.

• List Email Accounts - View your connected mailboxes. Required to identify which email account to send from when adding contacts to sequences.
• Add Contacts to Sequence - Add one or more contacts to an existing sequence. Specify the sequence, contacts, and sender mailbox id(s): one id as a string, or multiple ids as an array of strings for multi-mailbox or rotation (never guess ids; use values returned by List Email Accounts).
• Remove Contacts from Sequence - Remove contacts from an active sequence. Cancels pending outreach tasks while preserving historical engagement data.

Example Prompts

Here are prompts you can try once Apollo is connected:

Prospecting

• "Find VP-level marketing leaders at SaaS companies with 200-1000 employees in the Bay Area"
• "Search for engineering managers at companies using Snowflake in the healthcare industry"
• "Find CTOs at Series B fintech startups in London"

Enrichment

• "Enrich this person: Jane Smith at Acme Corp"
• "Get the verified email and phone number for the CTO of stripe.com"
• "Enrich these 5 leads and tell me which ones have verified emails"

Account Research

• "What can you tell me about apollo.io? Get their company details including tech stack and employee count"
• "Are there any open job postings at Figma right now?"

Contact Management

• "Create a contact for John Doe, VP Sales at Acme Corp, [email protected]"
• "Update the title for contact with email [email protected] to 'Senior Director of Engineering'"

Sequences

• "Show me my available email sequences"
• "Add these 3 contacts to the 'Outbound Q1' sequence using my Gmail account"
• "Remove contact with email [email protected] from the active outbound sequence"

Best Practices

• Be specific with filters - Include job titles, seniority levels, locations, and company attributes to get precise results. "VP of Sales at healthcare companies with 500+ employees in APAC" works better than "sales people at big companies."
• Use domains, not just company names - When enriching, include the company domain (e.g., stripe.com) for higher match accuracy.
• Enrich after searching -- People search returns profiles without contact details. Follow up with "Enrich the top 3 results" to reveal emails and phone numbers.
• Check your mailbox first - Before adding contacts to sequences, ask Claude to list your email accounts so you can specify which mailbox or mailboxes to send from (one id or an array of ids).
• One company at a time for enrichment - For best results, enrich contacts at one company per request rather than mixing multiple companies.
• Use deduplication when creating contacts - Ask Claude to "create this contact with dedup enabled" to avoid duplicates in your CRM.
