API referenceGet the tool inventory

Get the tool inventory

GET/v1/tool-inventory

Get the tool inventory.

Lists every tool name seen in the window, most used first, merged from three sources: tools declared in tools on LLM requests, tools the model asked to call, and tools/call requests through the MCP Gateway. Each tool says whether an MCP Gateway integration in the organization exposes a tool of that name (registered: false marks a shadow tool) and whether it was declared under more than one definition. The window defaults to the 30 days before end_time (default now). Each source contributes at most 500 tool names; truncated says when more exist. The summary counts are not capped.

With workspace_id, requires access to that workspace: an organization owner or admin, a member of the workspace, an organization-scoped va_ key with the admin role, or a va_ key scoped to the workspace. Without it, requires an organization owner or admin, or an organization-scoped va_ key with the admin role. Errors: 400 when start_time is not before end_time; 402 when the organization's plan does not include the tool inventory.

Authorization

  • AuthorizationBearer va_

    A platform API key (va_...), created under Settings > API keys. Scoped to an organization or one workspace, with an admin or member role. Used by the management API.

Query parameters

  • organizationstringrequired

    the organization's slug

  • workspace_idstring<uuid>

    a workspace id (UUID) to limit the inventory to that workspace's traffic and servers

  • start_timestring<date-time>

    start of the window, inclusive (ISO 8601 date-time with offset); default 30 days before end_time

  • end_timestring<date-time>

    end of the window, exclusive (ISO 8601 date-time with offset); default now

Responses

200application/json
  • start_timestring<date-time>

    Start of the window the inventory covers, inclusive (ISO 8601 date-time).

  • end_timestring<date-time>

    End of the window the inventory covers, exclusive (ISO 8601 date-time).

  • summaryobject

    Totals for the tool inventory's window.

    Child attributes
    • toolsinteger<int32>

      Distinct tool names in the inventory (the length of data).

    • unregistered_toolsinteger<int32>

      Tools seen in traffic that no MCP Gateway integration exposes.

    • changed_toolsinteger<int32>

      Tools declared with more than one definition in the window.

    • requests_with_toolsinteger<int64>

      LLM requests in the window that declared at least one tool.

    • tool_resultsinteger<int64>

      Tool-role messages (results fed back to the model) on LLM requests.

    • flagged_requestsinteger<int64>

      LLM requests whose tool results the always-on scan flagged (MONITOR, REDACT or BLOCK).

    • gateway_callsinteger<int64>

      Tool calls (tools/call) made through the MCP Gateway in the window, whatever their outcome.

  • dataobject[]

    Most used first; capped at limit.

    Child attributes
    • namestring

      The tool's name, as declared or called. Names come from your agents and MCP servers and are not verified.

    • declared_requestsinteger<int64>

      LLM requests whose tools[] declared it.

    • model_callsinteger<int64>

      Times a model asked to call it.

    • gateway_callsinteger<int64>

      tools/calls through the MCP Gateway.

    • definitionsinteger<int32>

      Distinct definitions (name + description + parameters) declared under this name. More than one means the tool changed - a rug pull or tool shadowing looks exactly like this.

    • first_seenstring<date-time>

      When the tool was first seen in the window, in any source (ISO 8601 date-time).

    • last_seenstring<date-time>

      When the tool was last seen in the window, in any source (ISO 8601 date-time).

    • virtual_keysstring[]

      Up to 10 virtual keys that declared it.

    • modelsstring[]

      Up to 10 models it was declared to.

    • registeredboolean

      An MCP Gateway integration in the org exposes a tool of this name. False = shadow tool.

    • serversobject[]

      Gateway servers that expose it (in the requested workspace, when one is given).

      Child attributes
      • slugstring

        The MCP Gateway server's slug.

      • namestring

        The MCP Gateway server's display name.

  • truncatedboolean

    True when more tool names exist than were returned.
