# dcl_commit

FINAL-STEP Leibniz Layer Crypto Commit ($0.01). Writes a trading/agent decision to the append-only Leibniz Layer audit chain and returns a Merkle-proof-style receipt: tx_hash (proof of this specific commit), chain_hash (the previous commit's hash, linking this one into the chain), and chain_depth (this commit's position in the chain). Unlike the evaluate_* tools, this call has no pass/fail verdict of its own — it always succeeds and simply seals the decision. Passing prior_checks is optional but recommended: it records which earlier pipeline steps (firewall/wallet/trade/MEV) this specific commit is downstream of, in one auditable record. Always run this LAST, after every other crypto-suite check has passed.

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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "dcl_commit",
    "arguments": {
      "agent_id": "<agent_id>",
      "decision": "<decision>"
    }
  }
}
```

## Why dcl_commit is rated Medium

Creates immutable audit log entry; irreversible but not destructive (read-only append); financial context elevates severity.

From the tool's own definition: "Writes trading/agent decision to append-only Leibniz Layer audit chain, returns Merkle-proof receipt"

Risk signals: Bulk/mass operation — affects multiple targets

## Use case

AI agents use dcl_commit to create or update resources in Dcl Trust Oracle, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Dcl Trust Oracle environment.

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "dcl_commit": {
      "limits": [
        {
          "counter": "dcl_commit_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
