# Which GTM MCP servers are free to use?

**The short answer**

42 unique products here have both an MCP server and a free to start gate, meaning you can sign up, get access and point an agent at them without paying anything or speaking to a salesperson. Free to start is a gate, not a price: everything on this list still meters something.

The MCP server itself is almost never the thing you pay for. What you pay for is what it calls: credits, seats, sends, lookups. A free server in front of a metered API is normal and it is not a trick, but an agent in a loop consumes a free tier considerably faster than a human clicking does.

## What this directory does and does not track about money

- **Tracked:** whether a solo operator can get API access at all, in four buckets, with a source. 57 entries are free to start, 101 paid self serve, 45 enterprise only, 83 unknown.

- **Not tracked:** prices, credit costs, quota sizes, rate limits, overage behaviour, or what happens to your data on a free tier. None of those should be inferred from anything here.

## The starter kit shape

If you want a chain rather than a single tool, the free and reachable jobs with the deepest coverage are [enrich a company from a domain](../jobs/enrich-company-from-domain.md) at 12 free entries, [find a work email address](../jobs/find-work-email.md) at 12, and [verify an email is deliverable](../jobs/verify-email-deliverable.md) at 6. That is enough to build a research and contact chain without a contract, and it is the cheapest honest way to find out whether any of this works for you.
