# validate_cross_network_settlement

Cross-Network Atomic Settlement Validator: OpenChainGraph compute node (settlement_mandate). Regulatory deadline: 2026-Q3 (ECB Pontes TARGET-link pilot end-Q3 2026; DTCC Collateral AppChain full production Oct 2026. Verify cross-network coordination patterns against current primary sources.). Deterministic OpenChainGraph compute node. By default (compute:"auto") inputs are computed server-side on Cloudflare Workers for gpu:false nodes with a registered kernel; compute:"browser" forces client-side execution and returns a browser delegation URL instead. gpu:true nodes always delegate to the browser. Inputs are processed transiently to compute the response and are not stored, logged, or retained. Use synthetic or anonymised inputs only. Exports an AP2 artifact with execution_hash for chain provenance. Consumes upstream artifacts from: art-56-tokenized-settlement-fit-diagnostic, art-59-settlement-asset-finality-classifier. Output feeds: 507-canton-dvp-atomicity-validator, 511-multi-currency-pvp-validator, cry-04-merkle-batch-verifier. Open at: https://ainumbers.co/chaingraph/art-58-cross-network-settlement-validator.html FV-status (published/proven/still-trusted for this spec): /fv-status/8b5ae30d812cd234cfb6068c4ce2022f01d10f2a358979b0f0d73421e09d2543.json — a snapshot, not a subscription; this receipt verifies offline regardless of whether that file is ever fetched.

## Parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `compute` | string | no | Compute mode (v0.4 Compute Binding). "auto" (default) = server for gpu:false nodes with registered kernels; "server" = force server-side; "browser" = always ret |
| `parent_hashes` | array | no | execution_hash values from upstream ChainGraph AP2 artifacts to chain from (sets chain.parent_hashes in the export). |
| `parent_tool_ids` | array | no | tool_id values matching parent_hashes, in the same order. |
| `policy_parameters` | object | no | Input parameters for this tool's decision function. For gpu:false nodes with a registered kernel, these are computed server-side when compute is "auto" or "serv |

Parameters from the server's own tool schema.

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

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

## Why validate_cross_network_settlement is rated High

Tool executes settlement validation logic on compute infrastructure, triggering external operations.

From the tool's own definition: "OpenChainGraph compute node, deterministic, server-side or browser execution"

## Use case

AI agents invoke validate_cross_network_settlement 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
