Paceloop MCP server

Endpoint

https://app.paceloop.app/mcp — JSON-RPC 2.0 over HTTP POST, stateless, no authentication, no rate card. Send tools/list to see what it offers.

What it can do

pressure_test_goal

Takes a metric, a target, a cycle length in weeks, and your store’s totals over a window (sales, orders, and sessions if you have them). Returns a verdict — realistic, a stretch, aggressive, or unrealistic — the run-rate your numbers project, the weekly rate the target actually requires, and a lower recommended target when the goal does not hold up.

propose_growth_plan

Same inputs. Names the single constraint your numbers point to, then proposes one to three weekly behaviors and an explicit list of work to cut. It is a proposal: nothing is saved anywhere, by anyone.

What it will refuse to do

These are the same refusals the app makes, for the same reason — a number nobody can verify is worse than no number.

• Leave out sessions and it reports conversion rate as unreadable rather than estimating it, and says a traffic constraint can be neither ruled in nor out.
• Give it more orders than sessions and it refuses a conversion rate outright: that ratio is not a conversion rate, and clamping it to 100% would swap one invented number for another.
• Ask for a margin plan and it will not give you one — it cannot see your costs, so it returns the plan for making the store measurable instead.
• Ask for a target it considers unrealistic and it names a lower number rather than agreeing with you.

What it does not touch

Nothing of yours. The server holds no store connection, no session, and no database: it is a pure function over the figures in your message. It does not log those figures — the only thing recorded per call is which tool ran, how long it took, and whether it succeeded. And it cannot read a Shopify store, including yours, because it has no way to reach one.

Connecting it

Most MCP clients take a remote server as a URL. Where a client wants JSON, the shape is:

{
  "mcpServers": {
    "paceloop": {
      "type": "http",
      "url": "https://app.paceloop.app/mcp"
    }
  }
}

A useful first message once it is connected: “Ask Paceloop whether $120,000 in 4 weeks is realistic — last 90 days were $90,000 across 900 orders and 45,000 sessions.”

The honest limitation

This server sees one window of numbers you typed. The app reads 90 days of your real analytics every time, watches the pace as the cycle runs, and holds you to the plan at a weekly check-in — which is the part that actually changes outcomes. Use this to find out whether your target survives contact with your own data. Use the app if the answer makes you want to do something about it.
