Best MCP servers for sales: Apollo, Hunter, LinkedIn

Apollo's official MCP server is the best single pick for sales agents: people and company search, enrichment and sequences at https://mcp.apollo.io/mcp, with Apollo sign-in and Apollo credits. Add Hunter for finding and verifying emails (50 free credits a month) and HubSpot's remote server for your CRM. LinkedIn has no official MCP server. Through Locus Pro, an Apollo people search costs 2 credits ($0.002). Prices checked November 10, 2026.

Which MCP servers are best for sales prospecting?

Each official server below needs an account and plan at its vendor. Plan details are from vendor pages on November 10, 2026.

Hunter charges 1 credit per email found, half a credit per verification and 1 credit per 10 Domain Search results. Its Discover search is free. Credits reset monthly and don't roll over.
Claude's plugin marketplace also lists ZoomInfo and Lusha plugins for teams that already pay for those tools.

Is there an official LinkedIn MCP server?

No. On November 10, 2026, the official MCP Registry listed 67 servers with LinkedIn in the name, and none was published under a LinkedIn namespace. LinkedIn does not offer one.

The popular community servers, such as stickerdaniel/linkedin-mcp-server, drive a browser signed in to your own LinkedIn account. Section 8.2 of LinkedIn's User Agreement bans scraping, bots and copying cookies, so running one breaks LinkedIn's terms for your account.

The safer route is a data vendor. Apollo enrichment accepts a LinkedIn profile URL as input, and Apollo's /apollo:enrich-lead skill turns a name, LinkedIn URL or email into a contact card.

How does the Apollo MCP server work and what does it cost?

Apollo hosts the server, so there is nothing to install. You sign in with Apollo OAuth and the server acts with your Apollo permissions. Some actions, such as enrichment, spend your Apollo credits, and they need credits left in your workspace to run.

In Claude Code, add it with claude mcp add --transport http apollo https://mcp.apollo.io/mcp, or install the Apollo plugin for ready-made skills: /apollo:prospect, /apollo:enrich-lead, /apollo:sequence-load and /apollo:analytics. In Cursor, add the same URL to mcp.json.

What does sales data cost through Locus Pro?

Locus Pro gives your agent Apollo, Hunter, Prospeo and BuiltWith from one credit balance, with no account at each vendor and no monthly plan. Each call shows its price first. 1,000 credits equal $1. Prices in the table are from the live catalog on November 10, 2026.

People search returns profiles without emails or phone numbers. Enrichment adds them.
The catalog also has LinkedIn lookups from third-party listings Locus has not reviewed. Check their terms before you rely on them.

What does sales data cost through Locus Pro?
Lookup	Locus endpoint	Credits per call	Dollars per call
Find people by title and company	apollo/people-search	2 fixed	$0.002
Enrich one person (email, LinkedIn URL or name)	apollo/people-enrichment	35.4 to 318.2, usually 35.4	Usually $0.0354
Enrich one company	apollo/org-enrichment	35.4 fixed	$0.0354
Find a work email	hunter/email-finder	Priced by request, with a cap	Quoted before the call
Verify an email	hunter/email-verifier	Fixed price per call	Quoted before the call
List emails at a domain	hunter/domain-search	Priced by request, with a cap	Quoted before the call
Search people	prospeo/search-person	1 to 10.1	$0.001 to $0.0101
A site's tech stack	builtwith/domain	50.5 fixed	$0.0505

What does a 100-lead list cost through Locus Pro?

Say an agent builds a list of 100 people with 5 Apollo searches and 100 Apollo enrichments. Through Locus Pro that is 10 + 3,540 = 3,550 credits, about $3.55, with no plan.

Checking the 100 emails with Hunter adds a fixed price per verification. A lighter path skips enrichment and has Hunter find and verify each email instead. Every call draws on the same balance, and the agent sees each price before it pays.

If you already pay for Apollo, its own server runs the searches and enrichments on credits you already have.

How do you choose a sales MCP server?

Match the server to the data you already pay for, then fill gaps.

Already an Apollo customer: use the official Apollo server.
Emails only, under 50 lookups a month: Hunter on its free plan.
Steady email volume: a paid Hunter plan, since lookups can cost less with your own Hunter account and API key.
Writing back to your CRM: HubSpot, alongside a data source.
Several vendors, bursty volume, one bill: Locus Pro.
LinkedIn data: a data vendor such as Apollo, not a browser-driving server.

Frequently asked questions

Does the Apollo MCP server cost extra?

There is no separate fee for the server. It runs on your Apollo account, and actions such as enrichment use your Apollo credits. If your workspace runs out of credits, those actions fail until you add more.

Can an AI agent read LinkedIn profiles without breaking the rules?

Not by logging in as you and browsing LinkedIn. LinkedIn's User Agreement bans bots and scraping. Use a data vendor instead, such as Apollo enrichment, which accepts a LinkedIn profile URL as input.

Which sales MCP servers work in ChatGPT?

HubSpot is in the ChatGPT plugin directory with Sign in with ChatGPT. Other remote servers, such as Apollo's or Locus Pro, can be added as a custom MCP server on ChatGPT for the web.

Can a sales MCP server return phone numbers?

Some can. Apollo enrichment has an option to reveal phone numbers, and through Locus Pro its price runs from 35.4 to 318.2 credits depending on the request. Lusha also markets verified phone numbers through its Claude plugin.
