The MCP Census

The MCP Census is a lookup service that checks public evidence for MCP servers before you install them. It returns a clear verdict of PASS, REVIEW, BLOCK, or UNKNOWN, helping developers make a quick first assessment. The site positions itself as a first gate rather than a malware scan or official registry.

The core feature is a searchable database of 48,800 MCP servers, including 15,517 GitHub links, 5,542 issues, and 30,828 remotes. Users can look up a single server, audit an entire MCP config in one call, and access the same facts via REST or MCP endpoints for agents. Free stats are unmetered, while search and lookup allow 10 unique names per day per IP without signup.

The service is aimed at developers, agent builders, and teams that install or manage MCP servers and want a lightweight preflight check. It is also useful for those who need programmatic access to server health and ownership data through API or MCP tools.

To use it, start with the free lookup or the unmetered stats endpoint to understand the data. For automated workflows, integrate the REST or MCP endpoint into your agent or config audit process. Keep in mind that the verdict is evidence-based and not a security guarantee, so pair it with other security checks.

Overall, The MCP Census offers a practical, evidence-linked way to screen MCP servers before installation, with useful free access and agent-friendly endpoints.
