Credits are the economic layer of Tally's MCP monetisation service. Simple. Deterministic. No surprises. Here's exactly how they work.
SUM(delta_credits) over the ledger.
Never manually set. Never negative. Never a lie.
Your MCP, your rates. Tally enforces the mechanics — you own the margin.
Set a flat credit cost per call, regardless of payload size. Your floor rate for every invocation.
base_invocation_cost: 10
Charge per token consumed. Set higher for compute-intensive tools, lower for simple lookups.
token_factor: 0.01
Charge per MB transferred. Covers egress costs for data-heavy MCPs like file servers or media tools.
bandwidth_factor: 20
Define how many credits each package tier delivers. Offer bulk discounts on the $1,000 package to reward high-volume consumers.
scale_multiplier: 1.25×
Tally rejects invocations when a consumer's balance hits zero. You are never exposed to negative balances.
enforce_balance: true
Each consumer sees their real-time balance, full credit history, and a breakdown of what's burning credits — all through the Tally portal.
portal_access: included
Tally takes 10% of gross consumer credit purchases — and nothing else. No monthly fee. No setup cost. No per-seat charge. No invoice at the end of the month.
Credits are prepaid. Your consumers pay before they consume. No invoice chasing. No receivables risk.
Stripe integration, consumer portal, receipts, balance notifications — all managed by Tally. Free.
If your MCP generates zero credit purchases, you pay zero. Tally's incentives are perfectly aligned with yours.
Hard architectural constraints — not preferences. They protect your consumers and they protect you.
When credits hit zero, invocations are rejected. No debt. No bill arrives later.
All usage is prepaid. There is no arrears mode. No invoice ever arrives for services already consumed.
Balance is visible at all times. Auto-replenish is opt-in. Nothing happens behind your consumer's back.
Balances are derived from the append-only ledger. No one can type a number into a field.
A billing service outage cannot fail your invocations. Credits and execution are architecturally separate.
