# workflow_conditional_step

Evaluate a condition against the stepResults argument and execute one of two tool branches. Supports built-in predicates: always_true, always_false, any_step_failed, success_rate_gte_N (N=0-100), variable_equals_KEY_VALUE, variable_contains_KEY_VALUE, variable_matches_KEY_REGEX, plus history-driven predicates history_failure_rate_gte_N / history_failure_rate_lte_N, last_run_failed[:workflowId], recent_steps_failing_L[:workflowId], history_fallback_rate_gte_N / history_fallback_rate_lte_N. History predicates read the workflow run store (the last 10 runs of the workflow named by the :workflowId suffix, or the current workflow when none is given); they evaluate false when no history exists. When stepResults is omitted, an empty set is used, so value-based predicates (variable_*, success_rate_gte_N, any_step_failed) will not match.

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "workflow_conditional_step",
    "arguments": {}
  }
}
```

## Why workflow_conditional_step is rated High

Conditionally executes arbitrary tool branches based on evaluated predicates, allowing workflow logic control with potential side effects.

From the tool's own definition: "Evaluate condition, execute tool branches, supports predicates"

## Use case

AI agents invoke workflow_conditional_step to trigger actions in Jshookmcp. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Jshookmcp:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "workflow_conditional_step": {
      "limits": [
        {
          "counter": "workflow_conditional_step_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
