GENERATED. This document is projected from the Zod MCP tool registry in `product/mcp/gtm.mcp` (one tool per public endpoint, 1:1). Do not edit it by hand; edit the tool definition and regenerate with `pnpm openapi:public`. Surface: the public `/api` contract of `gtm.service.id`, 77 operations. Internal (`/internal`) and health endpoints are deliberately absent; the code-faithful spec that documents those lives in `product/openapi/gtm.openapi.tech`. Conventions: - Auth is a bearer JWT, optionally narrowed by the `Team-SID` header. - Every success body is an MCP envelope: `success: true` plus one typed `operation` shape (`search`, `get`, `create`, `update`, `delete`, `metrics`, `group_by`, `action`), and a `meta` block with `trace_id` for support. - Every failure is the same `McpError` envelope with a code from a fixed 16-code taxonomy, so a client maps errors once. - Lists page with `page_size` (0 to 500, default 50) plus an opaque forward `cursor`; `page_size: 0` returns counts only. - On `GET` and `DELETE`, object-valued query parameters (`filter`, `sort`) travel as JSON text and array-valued ones repeat as `name[]=value`. - The MCP-only `_meta` field (usage analytics) never reaches the backend and is not part of this contract. version: '1.0' contact: name: GTM API url: https://gtm-api.com email: support@gtm-api.com license: name: Proprietary url: https://gtm-api.com/license servers: - url: https://app.gtm-api.com/id/v4 description: Production, through the app.gtm-api.com gateway - url: http://localhost:8021 description: Local Docker (gtm_id_nginx_dev) security: - BearerJwt: [] TeamSid: [] tags: - name: account_shares description: Registry package `mcp.id/account_shares`, served on MCP mount `id.access`. - name: api_keys description: Registry package `mcp.id/api_keys`, served on MCP mount `id.access`. - name: billing_payment_methods description: >- Registry package `mcp.id/billing_payment_methods`, served on MCP mount `id.billing`. - name: billing_products description: >- Registry package `mcp.id/billing_products`, served on MCP mount `id.billing`. - name: billing_subscriptions description: >- Registry package `mcp.id/billing_subscriptions`, served on MCP mount `id.billing`. - name: billing_transactions description: >- Registry package `mcp.id/billing_transactions`, served on MCP mount `id.billing`. - name: credit_transactions description: >- Registry package `mcp.id/credit_transactions`, served on MCP mount `id.credits`. - name: notifications description: >- Registry package `mcp.id/notifications`, served on MCP mount `id.platform`. - name: oauth_authorizations description: >- Registry package `mcp.id/oauth_authorizations`, served on MCP mount `id.access`. - name: oauth_clients description: Registry package `mcp.id/oauth_clients`, served on MCP mount `id.access`. - name: observability_requests description: >- Registry package `mcp.id/observability_requests`, served on MCP mount `id.platform`. - name: sessions description: Registry package `mcp.id/sessions`, served on MCP mount `id.identity`. - name: ssl_certificates description: >- Registry package `mcp.id/ssl_certificates`, served on MCP mount `id.platform`. - name: support_requests description: >- Registry package `mcp.id/support_requests`, served on MCP mount `id.platform`. - name: team_members description: Registry package `mcp.id/team_members`, served on MCP mount `id.identity`. - name: teams description: Registry package `mcp.id/teams`, served on MCP mount `id.identity`. - name: users description: Registry package `mcp.id/users`, served on MCP mount `id.identity`. paths: /api/observability/get-session: post: tags: - observability_requests summary: Get observability session description: >- Fetch the full tool-call history of one agent session by agent_session_id: total turns, total tool calls, and the per-turn tool-call breakdown.
