Works with Claude, ChatGPT, Cursor, and more
The Model Context Protocol standardizes how applications expose capabilities to LLMs. Instead of operating in isolation, your AI gains direct access to external platforms, live data, and real-world actions through secure, standardized connections.
This server provides 12 capabilities that interface natively with Claude, ChatGPT, Cursor, and any MCP client. No middleware. No custom integration required.
Finding reliable contact data used to be a nightmare of tabs.
Today, finding one verified email or checking a company's tech stack means opening six different browser tabs. You copy a name from LinkedIn, then paste it into a separate tool to check an email domain, and if that fails, you have to start over with another service just to find their phone number. It’s slow, frustrating, and you end up missing qualified leads because the manual process breaks down.
With this MCP, your agent handles all those micro-tasks behind the scenes. You tell it what you need—like finding a 'VP of Sales' at a target company—and it runs through `search_people`, then calls `enrich_person_data`. The result pops up in your chat window, complete and ready to use.
Apollo.io MCP gives you the full lifecycle control.
The biggest time sink is moving a qualified lead from 'found' to 'nurtured.' You find them, then copy their ID and manually enroll them into an email sequence in another dashboard. That friction stops momentum right when it should start.
Now, after your agent finds the perfect prospect, you simply ask it to `add_to_sequence`. The outreach starts instantly. It’s about keeping all your sales intelligence tasks—from search to enrollment—in one single conversation.
What you can do with this MCP connector
This MCP turns your agent into a dedicated sales analyst. Instead of spending hours switching between browser tabs to manually find an email address or verify if a company uses AWS, you just ask your AI client. You can search for organizations using search_companies by location and technology stack, then instantly pull the necessary data on specific employees via search_people.
Need to know if they're ready to buy? The system gives you deep firmographic insights like revenue and employee count. Once you have a qualified lead, you can enroll them directly into automated email sequences using add_to_sequence, all through natural conversation. Vinkius hosts this catalog so your agent can access the full power of B2B intelligence without needing to log into five different tools.
Your AI acts as the whole sales team, orchestrating outreach from initial search through sequence monitoring.

How Apollo.io MCP Works
- 1 Subscribe to this MCP and retrieve your dedicated API Key from your Apollo dashboard settings.
- 2 Connect your key in your AI client. You'll then use natural language commands to direct the agent to perform a search, like finding 'VP of Marketing at Acme Corp.'
- 3 The agent executes the necessary functions—for example, calling
enrich_person_data—and presents you with the full profile details and next steps.
The bottom line is, your AI client handles all the back-end querying and data fetching so you don't have to remember which tool does what.
Who Is Apollo.io MCP For?
Sales Development Representatives (SDRs) who are tired of manually cross-referencing spreadsheets, Account Executives needing instant deep-dive intel on key accounts, and Growth Marketers who need to automate the lead nurturing process from scratch.
The SDR uses natural language commands to build highly specific prospect lists for cold outreach campaigns.
The AE enriches key account data—like checking the tech stack or revenue using enrich_company_data—before they even schedule a call.
The marketer automates the lead lifecycle by finding contacts and enrolling them into automated email sequences via add_to_sequence.
What Changes When You Connect
- Stop guessing email addresses. Use
enrich_person_datato get verified phone numbers and emails for any contact, saving hours of manual verification work. - Go beyond basic search. With
search_companies, you can find organizations based on deep criteria like specific technology stacks or estimated revenue ($380B+), ensuring high-quality leads. - Automate the follow-up process. After finding a lead, use
add_to_sequenceto enroll them into an automated email campaign immediately through your agent. - Maintain visibility on account health. Use
get_credit_infoandget_api_healthto track usage limits instantly, so you never stop prospecting due to hitting a wall. - Coordinate complex strategies. Access deep firmographic data via
enrich_company_datato build perfect account strategies that go beyond just knowing the name.
Real-World Use Cases
Cold outreach targeting by tech stack
An SDR needs 20 companies in Chicago using AWS. They ask their agent to search_companies for 'AWS' and 'Chicago'. The agent returns a list of domains, which the user then asks it to enrich with contact data.
Deep-dive qualification on an account
An AE is calling Acme Corp. They ask their agent to enrich_company_data and search_people for 'VP of Marketing'. The agent provides the revenue, tech stack, and verified email in one chat window.
Nurturing a qualified lead
A marketer finds a high-value contact ID. Instead of emailing manually, they tell their agent to add_to_sequence using the provided ID, starting the automated nurture flow immediately.
Auditing outreach capacity
The team lead needs to know how many leads are left in the pipeline. They run a query asking for all active sequences and use list_sales_sequences to get a clear overview of ongoing campaigns.
The Tradeoffs
Searching contacts one-by-one
Copying an email address, then opening a new tab in the browser, and manually entering it into another tool to verify details.
→
Instead, ask your agent to enrich_person_data for a list of IDs. The agent handles all the batch verification using a single function call.
Forgetting usage limits
Running five complex searches and then getting an API error because you didn't know your credit balance was low.
→
Always check get_credit_info first. The agent tells you exactly when to slow down or renew before the search fails.
Creating sequences manually
Writing out a full email nurture campaign in a separate document and then trying to paste it into a platform that requires multiple steps.
→
Use list_sales_sequences to see what exists, then use add_to_sequence directly through your agent to start the outreach immediately.
When It Fits, When It Doesn't
Use this MCP if your process hinges on finding specific B2B intelligence: verified emails, tech stacks, or departmental structure. The core strength here is that you can combine multiple data points into a single natural language query—for example, 'Find the CTO at Acme using AWS.' Don't use this if all you need is to manage internal communication (use a messaging tool) or if your lead list is already 100% clean and verified. If your workflow requires simple task management, stick to project tools; here, you are buying intelligence, not just capacity.
