Availability in your MCP client also depends on your account connection, permissions, and active profile.
Connect

Use it from your MCP client

A profile controls which servers and tools your registered clients can use.

  1. Add this server to a profile and set up your personal connection if required.
  2. Select the tools and client instances to allow, then complete the profile’s access review.
  3. Once active, open Connect & test on the profile to get your client configuration and check connectivity.

Register your client in My workspace → My clients and save its token securely. A published listing does not by itself grant runtime access.

Gateway controls

Checked controls are enabled for this server’s hosted gateway. Consent and contracts are optional.

○
Policy engine
Only curator-vouched tools are callable — anything else is denied at the gateway.
○
Reflexive core
Per-client behavioral baselines flag anomalous activity.
○
Consent graph
Scoped grants are checked before a tool runs; grants can expire.
○
Contract broker
An active contract sets allowed tools and rate limits per client.

Catalog listing
The registry pins the exact upstream above and records every call made through the gateway in a tamper-evident ledger — visible to the client that made the calls.

Comparison covers the registry consumer runtime only. Catalog approval does not deploy code. External upstream deployment identity is not verified; personal connections and credentials are separate.
