A lead data MCP server lets an AI agent search, count and enrich people and companies through tool calls on a hosted endpoint. Agent builders and teams that work in Claude or Cursor need one.
The server is only the door. The price behind it decides what an agent can afford. One vendor's server only reads its documentation (BlitzAPI docs, September 2026). This page ranks seven that return records. LeadOcean is first because Pro is $499 a month flat and MCP is on every plan.

What we evaluated
- Data over MCP: records returned to the agent, or documentation only.
- Tool coverage: search, counts, enrichment, phones and export.
- Auth and plan gate: OAuth or API key, and which plan opens the server.
- Price model: what an agent call costs, and 1M records at list price.
- Limits that bite: rate limits, expiring credits, enterprise-only endpoints.
We read each vendor's pricing page and docs in September 2026. We ran no find-rate test.
1. LeadOcean: best for agents and volume
LeadOcean's MCP server at https://api.leadocean.io/mcp signs in with OAuth 2.1. It exposes 12 tools, from search_leads to find_phone and export_leads. count_leads is free, so an agent sizes an audience before it pulls one. Behind it sit 693M people and 63M companies.
Pro is $499 a month with no credits and no overage invoice.
Pros
- MCP on every plan, Free included.
- Free counts and filter lookups.

Pricing: Free is 1,000 records, one-off, no card. Pro is $499 a month, flat (LeadOcean pricing, September 2026).
2. FullEnrich: best for waterfall emails and mobiles
FullEnrich asks 25+ sources per contact. Its MCP server searches, enriches and exports, and asks before it spends credits (FullEnrich help, September 2026). MCP is on every plan, the trial included.

preview_costbefore large jobs.- No charge for a missed email.
Cons
- No free plan. A 14-day money-back guarantee applies to the first payment.

4. Apollo: best for reps who also sequence

Coresignal's server at mcp.coresignal.com/mcp/v2 has 5 tools and signs in with OAuth 2.1. The 2,000-credit free trial works with it (Coresignal MCP docs, September 2026).
Every step bills. entity_search is 20 credits a call and entity_fetch 20 credits per employee or company. email_enrich is 20 credits per email found, per the live server's tool text. The MCP docs page still lists 10, so check your credit meter on the first call (Coresignal MCP docs, October 2026).
