Billing & plans

mcppipe has three plans. The quotas, prices, and feature copy below are the single source mcppipe enforces and reports — the dashboard Billing page and the public pricing page render the same numbers from GET /api/plans.

Plans

Plan	Price	Bandwidth / month	Tool calls / month	Tunnels	Concurrent sessions / tunnel	Call history
Free	$0	5 GB	100,000	2	3	24 hours
Pro	$12 / month · $120 / year	25 GB	1,000,000	5	10	30 days
Scale	$39 / month · $390 / year	100 GB	5,000,000	20	25	60 days

Pro and Scale are flat per-account prices, not per seat. Scale is the step up when you outgrow Pro’s caps — 20 tunnels, each able to carry its own custom domain, and 60-day event retention.
Annual billing is roughly ten months’ worth of monthly price — two months free. Toggle monthly / annual on the dashboard’s Billing page or on the public pricing page.

All governance and observability features (per-tool JSON-RPC inspection, allow/deny tool policy, rate limits, field-level redaction, per-method metrics, rug-pull alerts, and zero-knowledge mode) are available on every tier, including Free. What a paid plan buys is scale — tunnels, sessions, volume and history — plus one capability: custom domains, which require Pro or above.

Concurrent sessions per tunnel

Each plan caps how many agent sessions can be connected to a single tunnel at once (so Claude, Cursor, and a CI job can share one tunnel — see Reliability). When you exceed the cap, mcppipe returns an honest session_limit error instead of silently killing an existing session. Raise the cap by upgrading the plan, or split traffic across more tunnels.

How quota is enforced

Bandwidth and tool calls are metered per calendar month and reset on the 1st.

Bandwidth and tool calls — when a tunnel goes over its monthly limit, mcppipe stops forwarding and returns HTTP 429 instead of passing the request through. The body is a JSON-RPC error envelope so an agent’s error handler treats it like any other tool error:
```
{
  "jsonrpc": "2.0",
  "id": 42,
  "error": {
    "code": -32000,
    "message": "Quota exceeded for this tunnel",
    "data": { "policy_code": "quota_exceeded", "reason": "monthly tool-call limit reached", "http_status": 429 }
  }
}
```
The response also carries an x-mcppipe-error: quota_exceeded header, and the dashboard surfaces an upgrade link. You are never billed for an over-limit request — it is refused, not metered as overage.
Tunnel count — creating a tunnel beyond your plan’s limit is refused with HTTP 402 Payment Required and a message like “the free plan allows 2 tunnel(s) — upgrade your plan to create more”. The cap check and insert run in one transaction, so two concurrent creates can’t both slip past the limit.
Concurrent sessions — over the per-tunnel session cap, mcppipe rejects the new session with a session_limit error.

A one-shot quota.warning event fires at roughly 80% of a limit, which you can receive via webhooks.

Checkout

mcppipe uses Paddle as the Merchant of Record. Paddle is the seller of record and collects and remits VAT / sales tax — your card details never touch mcppipe’s servers.

Choosing Upgrade to Pro or Upgrade to Scale on the Billing page opens a hosted Paddle checkout for the selected plan and cycle (monthly or annual). When payment completes, a signed webhook updates your plan — usually within seconds, with no restart and no action on your side. The cached plan is evicted immediately, so the new tier’s quota applies at once.

Managing your subscription

Once you have an active subscription, Manage subscription on the Billing page opens the Paddle customer portal, where you can update payment details, change plan, or cancel.

A cancelled subscription keeps its paid tier until the current period ends, then drops to Free.
An expired or unpaid subscription drops to Free immediately.

When an account returns to Free, the Free limits apply on the next request.

Usage meters

Billing page usage meters for data transfer and tool calls plus subscription status The Billing page shows current-period usage against your plan’s limits.

The Billing page (GET /api/billing) shows meters for the current month: data transfer, tool calls, and your tunnel allowance. mcppipe keeps the live, exact counters in Redis (and enforces against them); the meters are refreshed from a periodic snapshot into Postgres, so they can lag the live counters by a few minutes. Treat them as a usage gauge, not a real-time balance.
