# intoto_record_chain_run

Wraps the result of a run_chain call (server/auto compute mode) as standard in-toto links, one per successfully-executed step, plus a generated in-toto layout matching the chain's linear topology (each step MATCHes the previous step's product). Materials/products are keyed by the step's execution_hash; byproducts carries the raw execution_hash. All links and the layout are DSSE-signed with one ephemeral Ed25519 keypair scoped to this call (never persisted) — first shipping instance of "in-toto for MCP" per the 2026 research gap survey. Verify the bundle offline with the in-toto Link Builder & Verifier (chaingraph/intoto-link-builder.html verify tab) or a reference implementation. Steps that did not run (input_required, skipped_by_gate, gpu_browser_only, etc.) are listed in skipped[] rather than silently omitted.

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

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

## Why intoto_record_chain_run is rated High

intoto_record_chain_run triggers real processes with real consequences. An agent gone sideways doesn't fire it once. It starts dozens of builds, sends mass notifications, or burns through compute before anyone looks up.

## Use case

AI agents invoke intoto_record_chain_run to trigger actions in Ainumbers Mcp Apps. 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 Ainumbers Mcp Apps:

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