For the office of the CFO

Govern the spend.
Not just the traffic.

Tens of thousands of AI agents are transacting through metered MCP servers — and no one owns the budget line. Magertron gives finance a real-time lever on agent spend: per-tool budgets, chargeback by team, and a throttle at the gateway.

Agents are transacting.
Nobody is governing the spend.
MCP servers now bill on credit and usage models. Point tens of thousands of agents at them and an unbounded line item appears on the P&L — with no owner, no forecast, and no brake.

Metered, runaway cost

Usage-priced MCP servers turn agent activity into spend. At enterprise scale it compounds fast — and unpredictably.

No budget lever

There is no tool today that gives a CFO a real budget control on agent transactions. Finance can't cap what it can't see.

No attribution

Which team drove the spend? Which agent? Without showback and chargeback, the bill lands in one undifferentiated lump.

Every dollar of agent spend,
as it happens
A spend-anchored dashboard that speaks finance, not infrastructure. Committed pools and pay-as-you-go contracts represented honestly, side by side — down to the individual tool call.

Spend first. Infrastructure second.

The headline number is total spend — the one figure true for every contract, committed or usage-based. Commitment and pay-as-you-go sit beside it as context, never as the frame.

  • Total spend across every vendor, with success rate and active-contract count.
  • Committed vs pay-as-you-go partitioned automatically — no commitment-biased totals.
  • By-vendor rollup with committed, used, and remaining per contract.
  • Per-call drill-down — caller, department, tool, cost, and status for every transaction.

One lump bill becomes
a governed, forecastable line
An invoice-style chargeback statement that attributes spend down to the team, the cost center, and the individual caller — human user or service-account agent.

Spend, attributed to who spent it.

Per-vendor statements roll up by department and cost center, then break down to each caller with their share of the total. Value-based dollars computed from billable calls at the contract rate.

  • Department → caller hierarchy with cost-center codes and per-line percentages.
  • User and service-account attribution — every agent identified.
  • Per-vendor scoping so each statement foots to one contract.
  • Export to PDF — a finance-ready document, not a raw export.

Governance gets us in the door. Cost control makes us indispensable — and gives finance a budget lever it has never had on agent spend.
— the Magertron thesis
The CFO's guardrail —
not a kill switch
Budgets sized to keep the enterprise productive while capping the downside. Enforced in the transaction path, in real time, self-hosted in your own cluster.

Per-server & per-tool budgets

Set hard and soft spend caps at the granularity that matters. Throttle or block transactions that exceed quota.

Showback & chargeback

Attribute every dollar to a team, cost center, and agent. Forecastable cost from an unbounded line item.

Real-time gateway throttle

A transactional rate limiter in the data path. Enforcement at the gateway, in real time — before the spend lands.

Per-tool RBAC, default-deny

Every agent call authorized against policy — design-time and run-time. No tool callable until explicitly granted.

Data stays in your cluster

Self-hosted, mTLS to every upstream. Your regulated data and spend records never leave your perimeter.

Audit-ready evidence

OCSF-formatted logs stream to your SIEM — the complete trail auditors require. Validated with Splunk and Datadog.
