Where to list your AI agent tool: free vs paid directories
Short answer: you can get listed for free almost everywhere if you can wait — paid tiers buy speed, placement or a dofollow link. For MCP servers, publish to the official MCP Registry first.

Which one should you pick?
Want the biggest audience? PeerPush has an established builder community and daily/weekly awards; it is a general product directory, so agent tools compete with everything else.
Shipping an MCP server? Publish to the official MCP Registry, then submit to mcpservers.org — both are free and MCP-specific.
Building an open-source agent framework, coding agent or eval tool? AgentoolRank lists only agent tools and shows live GitHub activity, alternatives and head-to-head comparisons, and AI assistants can query it over MCP. It is new, so its own traffic is still small — weigh that honestly against the bigger directories.
