Agent Spend Mandate & Budget Ledger Verifier MCP

A local evidence verifier that binds supplied transactions to exact mandate IDs, compares merchant, category and currency, enforces validity windows and amount caps, detects duplicate transaction identities and computes deterministic budget usage.

What it creates

• result.json
• transaction-binding.csv
• budget-usage.csv
• issues.jsonl
• SPEND_MANDATE_REVIEW.md
• evidence-receipt.json

Requirements

• Windows 11
• Python 3.11–3.14
• An MCP-compatible client
• MCP_LICENSE_KEY from the MCP Marketplace purchase
• Internet access for initial and periodic license verification

License verification sends only the license key and public product slug. Buyer evidence paths, contents and generated reports remain local.

Install from a purchased source checkout

python -m venv .venv
.\.venv\Scripts\python.exe -m pip install .

MCP client configuration

{
  "mcpServers": {
    "spend-mandate": {
      "command": "spend-mandate-mcp",
      "env": {"MCP_LICENSE_KEY": "PASTE_THE_KEY_FROM_YOUR_PURCHASE"}
    }
  }
}

Run the client from the folder containing buyer-authorized evidence. All supplied paths must be relative to that folder.

Tool

build_spend_mandate_packet

• mandates: Spend-mandate JSONL
• transactions: Transaction JSONL
• policy: Spend-ledger policy JSON
• output_directory: new output directory

The tool returns structured JSON. ERROR means the request could not be processed.

CLI

The diagnostic command is unlicensed:

spend-mandate --json doctor

Protected commands verify the marketplace license before reading buyer files:

spend-mandate --json analyze --mandates examples/sample-input/mandates.jsonl --transactions examples/sample-input/transactions.jsonl --policy examples/sample-input/policy.json --out packet
spend-mandate --json show packet/result.json
spend-mandate --json verify packet/evidence-receipt.json

Product boundary

It does not verify signatures or identity, issue mandates, grant approvals, access cards or wallets, execute payments, refund transactions, handle disputes, enforce policy or attest legal compliance. All accepted evidence stays local. Apart from license verification, the package performs no network activity and has no telemetry.
