Apollo MCP Server
Search prospects, enrich contacts with verified emails and phones, manage CRM records, and enroll leads into outbound sequences from Claude.
Apollo's MCP server connects Claude (and other MCP clients) directly to the Apollo.io sales intelligence platform. It lets agents run the full outbound GTM loop from a single conversation: search Apollo's B2B database for people and companies matching an ICP, enrich contacts with verified emails and phone numbers, create or update contact and account records, and enroll prospects into outreach sequences. Analytics queries against Apollo data are also supported.
The integration is officially built and hosted by Apollo. For Claude.ai, Claude Desktop, mobile, and the API, Apollo ships as a native connector that you enable from Settings, Connectors. Authentication is OAuth against your existing Apollo account, so there are no API keys to manage. Data access and action limits inside the AI tool mirror your Apollo plan exactly, including credit consumption for enrichment.
For developer surfaces, Apollo also publishes an official plugin at apolloio/apollo-mcp-plugin that wires the same MCP server into Claude Code and Cowork via slash-command skills (/apollo:enrich-lead, /apollo:prospect, /apollo:sequence-load, /apollo:analytics). The connector launched in beta in 2026 and is available on all Apollo plans, including free, at no additional cost.

Option 1: Native Claude connector (recommended)
For Claude.ai, Claude Desktop, and the mobile app, Apollo is available as a built-in connector. No config files or API keys are required.
- In Claude, open a chat and click Connect your tools to Claude, or go to Customize, Connectors.
- Search for Apollo.io and click + Apollo.io.
- Review the terms and click Authorize to complete the OAuth flow against your Apollo account.
- Go back to Customize, Connectors and click Configure beside Apollo.io to set each action to Always allow or Approval required. Apollo recommends keeping approval required for credit-consuming actions.
The connector is per-user and must be enabled by each teammate individually. Any Apollo plan qualifies, including free.
Option 2: Claude Code or Cowork via the official plugin
Apollo publishes an official plugin at apolloio/apollo-mcp-plugin that wires the Apollo MCP server into Claude Code and Cowork.
In Claude Code:
/plugin marketplace add apolloio/apollo-mcp-plugin
/plugin install apollo@apollo-plugin-marketplace
Restart Claude Code, then run /mcp, select the Apollo server, and click Authenticate to complete the browser-based OAuth login.
The plugin exposes four slash commands:
/apollo:enrich-lead/apollo:prospect/apollo:sequence-load/apollo:analytics
Requirements
- An Apollo.io account (any plan, including free).
- Enrichment actions consume standard Apollo credits (typically 1 credit per person).
- Sequence enrollment may trigger live outbound messaging depending on your sequence settings, so verify volumes and sequence names before confirming.
- Build a targeted prospect list from natural language ("Find VP-level RevOps leaders at Series B fintechs in NYC") and load the verified contacts straight into Apollo.
- Enrich a CSV of leads with verified work emails, mobile numbers, and current titles before handing the list to SDRs.
- Triage inbound demo requests by enriching the contact, creating or updating the Apollo record, and adding them to the right nurture sequence in one turn.
- Run weekly outbound performance reviews by asking Claude to pull sequence and team analytics directly from Apollo.
- Keep CRM hygiene by deduping new contacts against existing accounts and updating stale fields without leaving the chat.
- "Find 50 Heads of Sales at US B2B SaaS companies with 100-500 employees that have raised in the last 12 months."
- "Enrich this list of LinkedIn URLs and return verified emails and direct dials."
- "Add the contacts you just found to my 'Q2 Outbound, Enterprise' sequence, but skip anyone already in an active sequence."
- "Create an Apollo contact for Jane Doe, VP Marketing at Acme, and attach a note about today's intro call."
- "Show me reply rates and meetings booked from my top three sequences over the last 30 days."
- Official, Apollo-built integration with OAuth, no API keys to rotate or store.
- Covers the full outbound loop in one server: search, enrich, CRM write-back, and sequence enrollment.
- Works on every paid and free Apollo plan; permissions and credits mirror the user's existing account.
- Native connector in Claude.ai plus an official Claude Code / Cowork plugin for developer workflows.
- In beta at launch, so feature surface and rate limits may change.
- Enrichment and sequence actions consume Apollo credits; bulk operations can burn through quotas quickly.
- Sequence enrollment can trigger live outbound messaging immediately, which is risky without strict approval gating.
- HubSpot MCP for CRM-first workflows with native contact, deal, and engagement management.
- Clay for multi-source enrichment and waterfall data orchestration, though without a first-party MCP server.
- Community Apollo MCP servers such as
thevgergroup/apollo-io-mcpif you need a self-hosted, API-key-based implementation.
