419 PASS Entries: Check the Result Against Your Deployment

The 20,629-entry public Registry snapshot contained 419 PASS entries. A dated public result does not guarantee safety for another version, configuration, or deployment.

TermMeaning
Public RegistryInspected MCP candidates searchable in the public Registry
Profile evidenceInspection-profile aggregates used to interpret public candidates in more depth
Review/action rowsEntries in WARN, NEED_REVIEW, RESTRICT, or BLOCK that require reasoned adoption review

Lead

Before connecting a PASS candidate, check that the reviewed version and observation date apply to the artifact and configuration you intend to use.

Key Findings

  1. The 20,629-entry public Registry snapshot contained 419 PASS entries. A dated public result does not guarantee safety for another version, configuration, or deployment.
  2. The 20,629 public Registry entries and 11,627 profile-evidence rows answer different questions and should not be mixed casually.
  3. The observation is an adoption input, not a final approval for a specific environment.
  4. Counts are snapshot evidence, so adoption review should check the observation date before treating the number as current state.

What We Observed

Before connecting a PASS candidate, check that the reviewed version and observation date apply to the artifact and configuration you intend to use. This lens matters because MCP servers are not just plugins; they are bundles of authority exposed to an AI agent.

Practical Reading

Even PASS candidates should be rechecked against the organization’s data sensitivity, user authority, and connected services. Review should record execution location, destinations, data touched, and unresolved evidence, not only the server name or README.

Limits

  1. The evidence uses public aggregate data and anonymized observations, not internal detection mechanics.
  2. Counts are snapshot values and will change as the Registry updates.
  3. This is not a claim that any named MCP server is safe or unsafe.

Conclusion

Even PASS candidates should be rechecked against the organization’s data sensitivity, user authority, and connected services. Keeping this evidence in the intake record makes the review repeatable across teams and deployments.


MCP Guard continuously turns public Registry and profile evidence into adoption-review signals for MCP security teams.

157 Operational MCP Entries Put Change Control In the Adoption Review

In a 20,629-entry Registry snapshot, MCP Guard observed 60 automation/workflow entries, 53 monitoring/observability entries, and 44 testing/quality entries. These 157 operational entries should be reviewed for environment boundaries, change approval, notification noise, audit logs, and rollback.

Pre-Adoption Review for Search, Documentation, and Analytics MCP Servers

In a 20,629-entry public Registry snapshot, MCP Guard observed 385 search/knowledge entries, 84 documentation entries, and 61 analytics/BI entries. These 530 entries sit close to answer evidence and internal knowledge, so adoption review should record source authority, freshness, citation or logs, outbound destinations, and read scope.

578 Identity, Data, and Cloud MCP Entries Need Control-Plane Review

Among 20,629 public Registry entries, 258 were security/auth, 203 database, and 117 cloud-provider entries. This 578-entry, 2.8% slice is small but close to identity, data, and cloud control planes, so adoption review should check credentials, scope, audit logs, and rollback before use.
