Tools 10 found in our last check

  • simulation.from_input

    Requires write key, content and target. Formats: compose/kubernetes/terraform-plan. Compose/manifests/Docker need host; cloud plans derive hosts. target.resourceKind: workload/Service/Ingress. Manifest placement: fixed workers/pod slots, pooled CPU/latency, not per-node. Cloud s…

  • simulation.inject_failure

    Requires simulationId and resourceId from simulation.create. Injects a bounded resource failure; returns updated state. Next tool is simulation.step, then simulation.recover_resource and simulation.metrics to confirm authoritative health. No API key required; demo limits apply.…

  • simulation.recover_resource

    Requires simulationId and resourceId from simulation.create. Requests reversible resource recovery; success does not prove healthy. Next tool is simulation.step, then simulation.metrics to inspect resource health. No API key required; demo limits apply. Read resource cwm://guide…

  • simulation.delete

    The likely next tool is simulation.create to use the freed slot. Prerequisite: a simulationId from simulation.create, or an active simulation in the preserved MCP session. No API key required; demo limits apply. Read resource cwm://guides/public/simulation.delete

  • scenario.list

    No prerequisites. Returns scenarios cards with id/name/summary. Filters precede stable ID paging: limit default 8, maximum 20; pass nextCursor as cursor until null. detailed=true restores rich cards per page. Next tool is scenario.get, then simulation.create with scenarioId. No…

  • scenario.get

    Requires scenarioId from scenario.list. Returns the complete selected graph, presets, assumptions and phase details. Next tool is simulation.create with scenarioId or the hydrated resources/connections. No API key required; demo limits apply. Read resource cwm://guides/public/sc…

  • simulation.create

    Create from scenarioId (scenario.list → scenario.get), or resources/connections for a custom graph. Returns id for simulation.step. Never blindly retry a timeout: creation may have succeeded. No API key required; demo limits apply. Read resource cwm://guides/public/simulation.cr…

  • simulation.step

    Requires simulationId from simulation.create (optional in demo). Returns completedSteps/currentStep; next tool is simulation.metrics. Retry same operationId/inputs. CWM_RAMP_GAP_NOT_ERRORS="true": owned AWS lean/2-app typical-v1 (500-RPS diagnostic) returns rampAveragingShortfal…

  • simulation.metrics

    Requires simulationId from simulation.create (optional in demo). Returns latest/history; full retains evidence. No new IDs. Next tool is simulation.step. CWM_RAMP_GAP_NOT_ERRORS="true": owned AWS lean/2-app typical-v1 (500-RPS diagnostic) returns rampAveragingShortfallPct=100*(1…

  • simulation.inject_traffic

    Requires simulationId from simulation.create and target traffic RPS. Returns applied traffic settings. Next tool is simulation.step, then simulation.metrics to read observed latency; do not assume its direction. No API key required; demo limits apply. Read resource cwm://guides/…
