The MCP Census is a lookup and preflight service for Model Context Protocol servers. Its homepage describes checking public evidence such as repository status, package information and hosted endpoint health, then returning PASS, REVIEW, BLOCK or UNKNOWN with supporting reasons. It is intended to help developers distinguish a maintained server from a lookalike, deprecated package or endpoint with too little evidence to assess.
The service offers individual lookups, configuration audits, an API and an MCP endpoint, with account-free access for some uses and credit-based plans for others. It also describes a changes feed for tracking updates to previously observed servers. The site's own scope statement is important: this is a first screening step, not a malware scan, penetration test or the official MCP registry. A favorable result does not establish that a server is safe for every permission or dataset. Teams should inspect the evidence and the access requested before installation.
