Our reading of Cold Leads, from the data

Cold Leads is a crm & marketing MCP server from anttka4cz, listed in the official MCP Registry.

Its endpoint requires sign-in or an API key just to list tools, so we haven't measured its token cost; we never use real credentials.

Maintenance is active: the last public signal was 5 days ago (2026-10-13). For comparison, 73% of crm & marketing servers are active or maintained.

With 0 GitHub stars it ranks #364 of 1,276 crm & marketing servers we index.

It runs either locally over stdio or as a hosted endpoint and needs one secret (COLDLEADS_API_KEY); use a scoped, least-privilege key.
