SpendNod is a MCP server that enforces AI agent spending limits, blocklists, caps, and mobile approval for transactions.

About

SpendNod is a hosted Model Context Protocol server that gives developers operational control over AI agent spending: configure limits, blocklists, and caps, then approve or deny charges from a phone when agents attempt paid actions. Register the remote MCP endpoint in Claude Code, Cursor, or another MCP client so procurement-style agent flows route through SpendNod policy instead of raw API keys with unlimited blast radius. It fits Operate → infra because it is ongoing governance for autonomous spend, not initial product coding or marketing. Small teams running agent swarms on metered LLM, SaaS, or payment APIs benefit most when they already have agents capable of initiating transactions. It does not replace accounting systems or fraud analytics platforms—it is a focused approval and policy layer you pair with your existing finance stack.

What it does

Cap and approve AI agent spend with limits, blocklists, and mobile transaction approval so autonomous tools cannot blow through your budget.

Who is it for?

Best when you're operating always-on agents that hit paid services and need simple spend governance.

Skip if: Projects with no agent-initiated payments or teams that already enforce spend solely via enterprise procurement portals.

What you get

After connecting SpendNod MCP, agent spend runs through your limits and you can approve transactions from your phone.

SpendNod

Your AI agent wants to buy something — should it ask you first?

SpendNod is a human-in-the-loop authorization gateway for AI agent transactions. Set spending limits, vendor blocklists, daily caps, and category restrictions. Approve or deny from your phone.

Quick Start

Claude Code

claude mcp add spendnod --transport http https://api.spendnod.com/mcp

ChatGPT

  }
}

What It Does

AI agents can now book flights, place orders, and transfer money on your behalf. SpendNod sits between your agent and every transaction — evaluating your rules in real-time and escalating anything outside your guardrails to you for approval.

Rule evaluation (in priority order):

Blocked vendors / blocked categories → instant deny
Auto-approve below threshold → instant approve
Require approval above threshold → escalate to human
Max per transaction → escalate if exceeded
Max per day (aggregate) → escalate if would exceed
Max per month (aggregate) → escalate if would exceed
Allowed vendors / allowed categories → escalate if not in whitelist
Default (no rules triggered) → auto-approve

Features

Spending thresholds — auto-approve small purchases, require human sign-off above a limit
Vendor blocklists — permanently block specific merchants
Daily & monthly caps — hard budget limits across all agent activity
Category restrictions — block or restrict entire spending categories (gambling, travel, etc.)
Rule templates — Conservative, Moderate, and Permissive presets to get started fast
Real-time dashboard — live activity feed, stats, and pending approvals at app.spendnod.com
Audit trail — every request logged with outcome, timestamp, and rule that fired
OAuth 2.1 login — Google and GitHub sign-in, no password required
