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.

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

Sign in to connect

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

Governance

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.

User ratings & feedback

Community feedback is separate from security certification. One rating per account; you can update yours.
