This page is the inventory of tools exposed by your upstream servers (GitHub, Linear, and so on). For Ultra’s own built-in tools —
ultra_status, ultra_add, ultra_reconnect, and more — see Ultra MCP Tools.Tool inventory
Each row is a unique server and tool pair. The table merges live usage stats with enforcement data:
Tools that have only ever been blocked (every call denied, with no successful traffic) still appear, with zeroed stats, so a tool you blocked before it was ever used does not vanish from the inventory.
Sort by any column (the default is Calls, highest first), filter by Tool name or Server, and group by tool or server. Use Export to download the inventory as CSV or JSON, and the Copy link button in a tool’s detail panel to share a deep link to it. See the dashboard guide for how export and shareable links work.
Tool detail
Click any row to open the tool’s detail panel. Its header carries a copy-link button and, for Hub admins, Govern and Block tool actions. Below that:- Overview: calls, success rate, average latency, distinct clients, and the tool’s blocked and anomaly counts.
- Security: recent blocked calls (each with the policy that blocked it and the client behind the call, plus a link to view them in the audit log) and recent anomaly findings.
- By client: how many calls each MCP client has made to the tool.
- Recent calls: the latest traces for the tool, with a link to view them in Traffic.
Blocking a tool
Blocking is available to owners and admins in Ultra Hub. On a standalone gateway, the Server Tools page is read-only.
- Block a single tool from its detail panel. This creates an organization-wide governance rule that denies that tool on that server, and the row picks up a Blocked badge.
- Block several tools at once by selecting their rows and choosing Block in the selection toolbar. A confirmation dialog summarizes how many tools will be blocked before the rules are created.
- Unblock works the same way, individually or in bulk, for tools that a tool-level rule is blocking. Tools carrying a Server blocked badge are blocked by a server-wide rule instead; unblock those from the Servers or Governance page.
- Govern opens the Governance page focused on the tool’s server when you need a more specific rule (particular clients, or a workspace or gateway scope) than a blanket block.
Use cases
- Find a tool fast. Search the whole fleet for a tool by name instead of opening servers one at a time.
- Spot risky tools. Sort by Blocked or Anomalies to surface the tools driving enforcement and anomaly activity.
- Shut down a tool organization-wide. Block a dangerous or deprecated tool in one click and confirm the denials in the audit log.
- Right-size governance. Start from a blanket block here, then narrow it to specific clients or scopes from the Governance page.
