Sprawl

Connect an agent to Sprawl

Your agent already writes code and runs on a schedule. What it can't do is keep a fleet running on your accounts after the session ends. Point it at Sprawl over MCP and it designs the operation; Sprawl runs it — each agent on its own model, on its own connected account, on its own schedule.

What you can do

• Design an operation — survey the user's repos and stack, then propose a complete blueprint: agents, their skills, their schedules and the accounts each one needs. Nothing is created until a human approves it.
• Pick a model per agent — a cheap one for the hourly sweep, a stronger one for the weekly analysis, inside a single operation. Independent of whichever model is doing the designing.
• Give each agent its own account — Sprawl holds multiple accounts per provider, scoped per operation: a work Gmail on one, a personal one on another; two X handles; two Slack workspaces.
• Stand it up, then check on it — provision the whole fleet atomically, and read back what ran and what it cost without leaving your editor.

Connect

The server is an HTTP MCP endpoint that speaks JSON-RPC 2.0 over POST:

https://sprawl.to/api/mcp

Authenticate with a bearer API key. Create one (free read-only keys are available) in account settings once you've created a free account, then pass it as Authorization: Bearer sprawl_sk_…

Quickstart

List the available tools to confirm your key works:

curl -s https://sprawl.to/api/mcp \
  -H "Authorization: Bearer sprawl_sk_..." \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

Add to an MCP client

Most MCP clients accept an HTTP server config like this:

{
  "mcpServers": {
    "sprawl": {
      "type": "http",
      "url": "https://sprawl.to/api/mcp",
      "headers": { "Authorization": "Bearer sprawl_sk_..." }
    }
  }
}

A machine-readable descriptor (tools, auth, and pricing) is served without auth at /.well-known/mcp/server-card.json.

Pricing & metering

There is no subscription. Every account starts with $3 of usage, each run draws its own price from that balance, and you add more whenever you want — from $5, never expiring.

When an agent runs low, sprawl_get_usage returns the remaining balance in dollars, what has been spent this month, and the billing page to add more. Adding balance is the account owner's action — an agent can surface the link, and cannot charge a card.

Agentic checkout (ACP)

Sprawl also exposes Agentic Commerce Protocol checkout endpoints (the open standard by OpenAI & Stripe) for adding balance, so an agent can run a standards-based checkout itself.

• Public product feed: GET /api/acp/feed
• Create, re-price, retrieve, or cancel a session: /api/acp/checkout_sessions (bearer sprawl_sk_ auth)

Payment completion via Shared Payment Token is not yet enabled. Until it is, a session can be created and priced but not paid — the account owner adds balance from the billing page above.
