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. ## The list - [Airbyte](../tools/airbyte.md) Official MCP · Free to start Open-source/cloud ELT platform with 600+ connectors moving data from SaaS tools and databases into warehouses;

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 15 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. ## Sources - [The GTM MCP Directory, free API tiers](../lists/free-api-tiers.md) this site - [The GTM MCP Directory, by access gate](../gates/index.md) this site Every number on this page is generated from directory.json at build time and carries the date it was baked: 2026-09-27.
