The short answer
62 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. 78 entries are free to start, 132 paid self serve,
79 enterprise only, 949 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 at
15 free entries,
find a work email address at 12, and
verify an email is deliverable 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.
Sources
Every number on this page is generated from directory.json at build time and carries
