7 Best MCP Servers for Sales in 2026 (Compared)

A sales MCP server is a hosted endpoint that lets an AI assistant search, count and enrich buyers through tool calls. Agent builders, RevOps and reps who work in Claude, ChatGPT or Cursor need one.

The server is only the door. What decides the choice is the meter behind it: credits, seats, rate limits and whether a 1M-record pull has a public price. Most of these vendors publish no 1M price, and that is the gap this page fills. We rank seven servers on the same criteria, from their own pricing pages and docs.

TL;DR

"1M records" means 1M work-email lookups that return a result. Credits per lookup differ by vendor. Figures are list prices.

What we evaluated

• Data over MCP: the server returns records to the agent, not only documentation.
• Tool coverage: search, counts, enrichment, phones and export in one server.
• Auth and plan gate: OAuth or API key, and which plan opens the server.
• Price model: what one agent call costs, and what 1M records cost at list price.
• Limits that bite: rate limits, expiring credits and enterprise-only endpoints.

We gave each vendor the same four jobs on paper: size a list, search it, enrich one person, then price 1M lookups. The answers come from each vendor's pricing page and docs, read in September 2026. We ran no live find-rate test, so accuracy claims are the vendor's own and are marked as such.

1. LeadOcean: best for agents and volume

LeadOcean's MCP server at https://api.leadocean.io/mcp signs in with OAuth 2.1, so no key is pasted into the client. It exposes 13 tools, from search_leads and get_lead to find_phone and export_leads. Behind it sit 693M people and 67M companies (LeadOcean docs, October 2026).

The job that matters for agents is sizing. count_leads and count_companies are free, so an agent checks how big a segment is before it spends a record. One search pages to 10,000 rows, then asks the agent to narrow the filters.

The price model is the point. Free is 1,000 records for life, with every feature, and Agency is $497 a month with no per-record price and no overage invoice. Paid plans have a fair-use pace instead of credits. That pace is where a heavy agent loop is decided, so read it before a large run.

Pros

• MCP on every plan, Free included.
• Free counts, filter lists and enum lookups.
• 200 requests a second on Agency, 5 on Free.
• Email status on every record.

Cons

• No sequencer, dialer, CRM or browser extension. The app is an Exports page.
• No waterfall enrichment, jobs or intent data.
• Bulk CSV export is not on Free.

Best for: agents, developers and RevOps that need volume and a fixed bill.

Pricing: Free is 1,000 records, one-off, no card. Solo $97 and Agency $497 a month (LeadOcean pricing, October 2026).

2. Apollo: best for reps who also sequence

Apollo runs an official MCP server at https://mcp.apollo.io/mcp over Streamable HTTP. It signs in with OAuth 2.0, or takes an API key for headless clients. Any plan qualifies, Free included (Apollo developer docs, September 2026).

Through the server an agent can search, enrich, add contacts to sequences and update the CRM (Apollo MCP, September 2026). The meter is seats plus credits. An email costs 1 credit and a phone number 8, and credits expire each cycle (Apollo API pricing, September 2026).

At volume the seat model is the problem. Basic gives 2,500 credits per seat a month, so 1M email lookups mean hundreds of seats.

Pros

• MCP on every plan, no extra cost.
• The agent can act: sequences and CRM updates.
• Enrichment runs at 1,000 requests a minute on paid plans (Apollo rate limits, September 2026).

Cons

• Credits are pooled by seat and expire at the end of each billing cycle.
• No public price for add-on credits.
• Built around a rep workspace, not a data feed.

Best for: reps who prospect and send from one workspace.

Pricing: Free with 75 credits a month. Basic $65, Professional $99, Organization $149 per seat a month. Billed yearly: $49, $79, $119 (Apollo pricing, September 2026).

3. ZoomInfo: best for teams already on ZoomInfo data

ZoomInfo has an official MCP server that works with Claude, ChatGPT, Cursor and Copilot. ZoomInfo claims 100M+ companies and 500M+ contacts. It needs a free GTM AI account or an existing ZoomInfo subscription with data credits (GTM AI docs, September 2026).

The GTM AI route is the self-serve one. Search, lookup and find-similar are free, and one data credit enriches or exports one record. A record is charged once per 12 months, so re-enriching it inside that window costs nothing (ZoomInfo API docs, September 2026).

The ladder falls from $0.45 a credit at 100 credits to $0.25 at 100,000 credits for $25,000. Past that it is Enterprise sales (GTM AI pricing, September 2026).

Pros

• Free search and lookup. The free tier includes MCP, API and CLI access.
• Records are charged once per 12 months.
• Enterprise accounts get custom rate limits.

Cons

• Accounts that hold only recurring monthly credits cannot use the server.
• The self-serve slider stops at 100,000 credits.

Best for: teams already on ZoomInfo data that want an agent in front of it.

Pricing: GTM AI is pay as you go from $20, with 1,000 data credits free at signup and no card. The Builder package is capped at 5 requests a second (GTM AI pricing, September 2026).

4. FullEnrich: best for waterfall emails and mobiles

FullEnrich asks 25+ sources per contact before it returns an email or a mobile. MCP, API, search and bulk CSV are on every plan, the free trial included (FullEnrich pricing, September 2026). The server searches, enriches and exports.

The meter is per result. A work email is 1 credit, a mobile 10, and a miss or landline is 0 (FullEnrich docs, September 2026). The API allows 60 calls a minute across Enrich, Reverse Email and Search, with up to 100 contacts per bulk request (FullEnrich docs, September 2026).

Pros

• Waterfall across 25+ sources in one call.
• No charge when nothing is found.
• Unlimited users on every plan.

Cons

• Mobiles cost 10 credits each.
• No public 1M price. The top monthly tier is 100,000 credits.
• 60 calls a minute caps a fast agent loop.

Best for: agents that need waterfall mobiles and emails on thousands of contacts.

Pricing: Pro from $29 a month for 500 credits, or $26 a month billed yearly for 6,000 credits a year. Trial is 50 credits, no card (FullEnrich pricing, September 2026).

5. Lusha: best for reps who want a browser-first tool

Lusha's MCP server at https://mcp.lusha.com has 50 tools. It shares the REST API credit pool (Lusha MCP tools, September 2026). Every user gets an API key on every plan, Free included (Lusha API guide, September 2026).

Data Waterfall is on all paid plans for API and MCP. It costs 2 credits per work email and 8 per phone, only on a successful match.

Lusha's docs disagree on one point: whether a request with no match costs a credit. The API guide says a minimum of 1 credit, and the MCP tools page says none. Test one miss before a large run.

Pros

• 50 MCP tools on a shared credit pool.
• Waterfall for emails and phones on paid plans.
• A free plan with an API key.

Cons

• Plans are built for seats, so volume is quoted. The top public tier holds 10,000 credits a month.
• Per-key quotas are small: Pro is 50 requests a minute and Premium 300.
• The no-match billing rule is unsettled in the docs.

Best for: reps who want contact data in the browser with an MCP server on top.

Pricing: Free is 40 credits a month. Starter $49.90, Pro $69.90, Premium $399.90 a month. Billed yearly: $37.45, $52.45, $299.95 (Lusha pricing, September 2026).

6. Hunter: best for email finding at the lowest public bulk rate

Hunter has an official remote MCP server at https://mcp.hunter.io/mcp. It runs over Streamable HTTP with a Hunter API key in a header, and Hunter says it is included in all plans at no extra cost (Hunter MCP, September 2026).

Hunter is an email finder and verifier first. It is the only credit vendor here with a published 1M price. The Data Platform calculator prices 1,000,000 Search credits at $6,900, paid once and valid 12 months (Hunter Data Platform, September 2026).

Rate limits are per endpoint. Email Finder and Domain Search allow 15 requests a second and 500 a minute (Hunter API docs, September 2026).

Pros

• A published 1M price, $6,900 on Data Platform.
• Unlimited team members share one credit pool.
• Limits are documented per endpoint.

Cons

• Built around email finding, not a full people database.
• Key-based auth, so no OAuth sign-in for the MCP server.
• Verification credits are extra, from $11 per 1,000.

Best for: teams that need work emails by domain at a low, known price.

Pricing: Free is 50 credits a month. Starter $49, Growth $149, Scale $299 a month. Billed yearly: $34, $104, $209 (Hunter pricing, September 2026).

7. Crustdata: best for live data and change watchers

Crustdata's hosted server is at https://install.crustdata.com/mcp. Interactive clients use OAuth, and code uses an API key as a bearer token (Crustdata docs, September 2026).

Search is cheap at 0.03 credits per result. Person enrich is 1 to 7 credits, and a work email through it totals 2 credits. The 1-credit contact endpoint is for enterprise plans only (Crustdata docs, September 2026).

The pricing page lists no plan names and no dollar price per credit (Crustdata pricing, September 2026). You cannot cost a 1M run without a quote.

Pros

• OAuth for clients, API key for code.
• Cheap search at 0.03 credits a result.
• Change watchers that a static database lacks.

Cons

• No public dollar price per credit.
• Default limits are 15 requests a minute on enrich and 30 on search (Crustdata docs, September 2026).
• Purchased credits expire 12 months after purchase (Crustdata docs, September 2026).

Best for: signal-driven agents that need fresh data more than volume.

Pricing: Credit based, with no public price list (Crustdata pricing, September 2026).

Verdict

The best MCP server for sales depends on who is on the other end of it. For an agent that pulls at volume, LeadOcean wins: the price stays $497 a month and counts are free. Apollo wins for reps who sequence, since its agent can act after the lookup. ZoomInfo fits teams already on its data and FullEnrich fits waterfall mobiles. Lusha suits browser-first reps, Hunter wins on a known bulk email price, and Crustdata wins on live signals. Start on the free plan.
