Lead generation MCP servers fall into four groups: prospect databases for finding companies and people, enrichment tools for verified work emails and phone numbers, workflow layers that waterfall across providers, and niche sources such as local businesses from Google Maps. Below: what each covers (prices checked October 2026), how it connects, and which to pick.

Limits: A local server, and you manage your own API key.

Manifold

Manifold is a hosted lead and contact search MCP. It covers company search, people search, and finding and verifying work emails. People search returns names, titles and companies; to get an address, use leads_get_email for one person or leads_get_domain_emails for the addresses known at a domain. One person's email is looked for across several email finders in turn and verified before it is returned.

To build a target list, search for companies with leads_search_companies, then for people there by title with leads_search_people, then use leads_get_email for each person worth contacting. The same server also covers SEO, AI visibility, social, Reddit and ads data. For tool details and credit costs, see the leads tools documentation. To compare it with Clay's own server, see Clay MCP alternative.

Manifold is pay per call. Every workspace gets 500 free credits. After that, Pro starts at $20/mo. No API keys of your own are needed.

Limits: Company and people search and work emails only, with no CRM write-back or sequencer integration.

Best for: One hosted server across SEO, social, ads and leads. Per-call credits, and no API keys of your own to manage.

Pairing with a CRM MCP

Once you have a lead list, HubSpot and Salesforce both run MCP servers that let your agent write contacts back to your CRM. HubSpot MCP is hosted at https://mcp.hubspot.com and reads and writes contacts, companies, deals and tickets. Salesforce's MCP server for Marketing Cloud Engagement works with data extensions, journeys and automations.

For a full comparison of both, see the best MCP servers for marketing.

Example lead generation prompts

Once a lead generation server is connected, your agent can handle multi-step prospecting workflows from a single conversation. Here are five prompts you can paste into Claude or ChatGPT:

Build a target list from an ICP: "Find B2B SaaS companies in the US with 50 to 200 employees. Then find the VP of Marketing and Head of Sales at each company. Return a table with company name, person name, title, and LinkedIn URL."

Find and verify work emails: "Take this list of 20 people and find verified work emails for each. Flag anyone where no email was found and tell me the success rate."

Check email deliverability before a campaign: "I have a CSV of 100 email addresses from last year's event. Check which ones are still deliverable and which have bounced or are invalid."

Research an account's buying committee: "Find the decision-makers at acme.com for a marketing automation purchase: CMO, VP of Marketing, Marketing Ops lead, and Head of Demand Gen. Include their work emails and a one-line summary of their background."

Combine signals for warm outreach: "Find companies in fintech that raised Series B funding in the last 6 months and are hiring for growth roles. Return the CEO and VP of Sales at each, with verified emails."

A note on compliance

Verified emails are a deliverability signal: they tell you an address exists and accepts mail, not that the recipient has consented to receive your message. Outreach must follow consent and anti-spam rules in the jurisdictions where you operate, regardless of whether the email was verified. Work with your legal and compliance teams to ensure your campaigns meet those standards.

Which lead generation MCP server should you use?

Pick by what you already pay for and whether you need a workflow platform or raw data.

You already use Clay. Use Clay MCP, so your reps can access data from 200+ providers and run ops-managed workflows from their AI tools. The Clay MCP setup guide covers the admin controls, credit limits and common issues.

You already use ZoomInfo, Amplemarket or LeadIQ. Use their MCP servers. Your agent uses the data you already pay for, and the OAuth flow is fast.

You want verified emails and phones across multiple providers. FullEnrich MCP runs a waterfall that checks 20+ sources in turn.

You want to test with a free plan. Vibe Prospecting and LeadIQ both list free tiers. Test them, then decide whether to upgrade.

You need local business leads from Google Maps. Scrap.io MCP searches Google Maps business data by category and location.

You are building an agent and want an API-first enrichment stack. AgentEnrich charges per call rather than per seat.

You want one server for SEO, social, ads and leads, with per-call pricing and no API keys. Manifold charges per call, includes 500 free credits per workspace, and needs no API keys of your own.
