**The short answer.** The best tool for prospecting with Claude is one connection that covers the whole job: Layrcake finds people and companies, gets and verifies emails, reads buying signals and public posts, researches accounts with sources and drafts campaigns a person approves. For single jobs: Apollo or ZoomInfo's GTM AI for contact databases, Lusha for signals, FullEnrich or Hunter for emails, Clay for table-based workflows, and Claude's own web search for open-web reading.

## 1. Layrcake: every prospecting job in one connection

Connect `https://mcp.layrcake.dev/mcp` in Claude and ask for the job in one sentence:

**Claude**

```
Find 20 heads of sales at SaaS companies in London with 20 to 200 staff. Verify every email, find a recent reason to reach out to each one, and draft a three-step sequence that opens with it. Stop before sending.
```

In our run on 1 October 2026, Claude found 20 people, got 16 emails, kept 15 after a second check, found recent LinkedIn activity for all 15 and drafted the sequence: 145 credits ($1.45), with the launch waiting on an approval link. A lookup that finds nothing is free, and credits never expire. The [full run](https://layrcake.dev/guides/claude-lead-generation) has every tool call.

## 2–3. Contact databases: Apollo and ZoomInfo GTM AI

**Apollo** brings its contact database, sequences and tasks into Claude through a hosted MCP server, on plans from a free tier to $119 per seat a month billed annually ([Apollo pricing](https://www.apollo.io/pricing)). **ZoomInfo's GTM AI** brings company, contact and intent data, free to start with 1,000 data credits and pay-as-you-go from $20 ([GTM AI pricing](https://gtm.ai/pricing)). Compare them with Layrcake: [vs Apollo](https://layrcake.dev/guides/layrcake-vs-apollo), [vs ZoomInfo](https://layrcake.dev/guides/layrcake-vs-zoominfo).

## 4–6. Emails and signals: FullEnrich, Hunter and Lusha

**FullEnrich** finds work emails and mobiles across 25-plus sources and charges nothing when it finds nothing ([FullEnrich](https://fullenrich.com/pricing.md)). **Hunter** finds and verifies emails, with its MCP included on all plans ([Hunter](https://hunter.io/mcp)). **Lusha** adds dated buying signals to contacts, with 50 MCP tools and a listing in Claude's directory ([Lusha](https://www.lusha.com/pricing/)). For how finding and checking emails works, read [our email guide](https://layrcake.dev/guides/find-work-emails-with-claude).

## 7–8. Workflows and the open web: Clay and Claude's web search

**Clay** runs enrichment as table workflows across 150-plus providers and connects to Claude; see [Claude vs Clay](https://layrcake.dev/guides/claude-vs-clay). **Claude's own web search** reads company websites and news without another tool, which is enough for a quick look at one account.

## How do you pick?

Start from the job, then count connections. If Claude has to stitch three tools together for one list, its context fills with tool descriptions and its choices get worse. One connection that covers the job is faster, cheaper to run and easier to check. [Connect Layrcake to Claude](https://layrcake.dev/claude) in about two minutes; new accounts get 300 free credits.
