MCP Census Rule: Gate Client MCP Servers Before Install, Not After the Incident
Should an agency add MCP Census as a paid line item in its agent delivery workflow, or is the free tier enough to cover client MCP server vetting? Put every client MCP server through a Census audit before installation, and move off the free tier to the $19 builder plan the moment anonymous lookups or the 1,000-credit monthly grant stop covering your delivery volume.

“Should an agency add MCP Census as a paid line item in its agent delivery workflow, or is the free tier enough to cover client MCP server vetting?”
Put every client MCP server through a Census audit before installation, and move off the free tier to the $19 builder plan the moment anonymous lookups or the 1,000-credit monthly grant stop covering your delivery volume.
Agencies treat a PASS verdict as a security clearance and sell it to clients as comprehensive agent security, when MCP Census explicitly is not a malware scanner or pen-test tool; the fix is to position it as the pre-install gate and pair it with separate review for anything the census flags REVIEW or UNKNOWN.
MCP Census returns PASS, REVIEW, BLOCK, or UNKNOWN per server with reasons and an exit code, so a single /v1/audit call can gate an entire .mcp.json before an agent touches client systems. The free plan's 1,000 credits each UTC month and 10 anonymous lookups/day per IP suit a one-off check, while the $19 builder tier adds 2,000 credits, non-expiring purchased credits, and REST, MCP, stamp, and watches, which is what retainer work actually needs. It is a first gate, not a malware scanner or pen-test, so scope the engagement as server vetting rather than full agent security.
- •The agency ships agent stacks in Claude Code, Codex, Cursor, VS Code, or GitHub Actions and installs third-party MCP servers on client infrastructure
- •Delivery runs more than roughly 10 server lookups per day across active client configs, which exceeds the anonymous per-IP cap
- •A client contract or procurement review requires documented evidence artifacts (stamped verdicts) before go-live
- •The agency wants preflight checks in CI plus webhook watches on servers already in production
