Cohort tools are hidden and uncallable unless both the local COLABHIVE_MCP_COHORT_TOOLS_ENABLED=true flag and the Builder capability admit them. The same gate is applied at discovery and direct call-by-name. Restrictive Builder keys require inference:execute.

The stable tool names are:

  • cohort_capabilities
  • plan_cohort
  • run_cohort (accepts idempotency_key)
  • get_cohort
  • explain_cohort
  • cancel_cohort

All are kind=operation; read-only/destructive/idempotent annotations and side effects are explicit. The namespaced _meta["com.colabhive/cohort"] block exposes stability, side effects, billing behavior, request/asynchronous latency and the applicable latency/cost budget fields. Discovery is tenant-capability gated; plan_cohort and run_cohort additionally preflight any explicit endpoint_id against its effective rollout, health and compatibility before issuing a POST. Intermediate tensors are never MCP content. The stdio and hosted transports follow the same official-SDK/Inspector conformance contract.
