The short answer
An MCP marketplace is where developers discover Model Context Protocol servers — the connectors that let AI assistants use external tools. OnlyFoundrs is the marketplace layer registries lack: listings ranked by real usage, liveness-verified, and searchable by the workflow you need — 'query my database' finds the server that does it.
Registries catalog; they don't curate
MCP registries are exhaustive and useless at once — thousands of entries, flat ordering, no quality signal. A marketplace is what the ecosystem actually needs: rankings that reflect what builders keep installed, verification that abandoned repos get flagged, and discovery by the job rather than by repo name.
Marketplace mechanics for the MCP ecosystem
OnlyFoundrs treats MCP servers like products, not repos: permanent listings, community ranking, liveness checks, and semantic search by the workflow you want to automate.
Usage-ranked catalog
Servers rise on real adoption signals — not first-committed ordering.
Verified maintained
Liveness checks flag abandoned servers instead of letting them clog discovery.
Workflow search
Describe the job — semantic matching routes to the server that performs it.
Free to list
MCP builders get the same permanent, indexed, community-ranked page as every tool.

FAQ
Is there an MCP marketplace?
OnlyFoundrs functions as the MCP marketplace — servers are listed, ranked by real usage, and discoverable by the workflow they automate, unlike flat registries.
How is a marketplace different from the MCP registry?
The registry catalogs everything with no quality signal. A marketplace ranks by usage and verifies maintenance — you find what works, not what exists.
Can I sell or promote my MCP server here?
Listing is free and permanent. Ranking is earned through community engagement — there's no paid placement, just visibility for what people use.
