spendctl
Spend policy for AI agents that pay (x402, MPP). Login-free sandbox, real sidecar, no real funds.
What it does
spendctl is an MCP server, a connector that lets an AI assistant use it as a tool. It is hosted: an assistant connects to it over the internet, nothing to install.
No capability identified yet from its description.
Facts come from the Official MCP Registry, as declared by the publisher. Capabilities are matched automatically (low confidence). None of this is a test of the tool.

6 tools offered to AI assistants
sandbox_create· Creates an isolated spendctl sandbox: a real spendctl sidecar with a throwaway wallet, mock paid APIs and a mock facilitator. No real money moves and nothing outside the sandbox is reachable. Returns the sandbox_id to pass to the other toolsandbox_pay· Fetches one of the sandbox's paid endpoints (HTTP 402, x402) through the spendctl sidecar: https://weather.sandbox.spendctl.dev/weather?city=<name> ($0.01) or https://search.sandbox.spendctl.dev/search?q=<query> ($0.02), as listed by sandbocheck_budget· Shows the sandbox agent's spending limits, what has been spent in each window, and what is left.list_receipts· Lists the sandbox agent's recent payment attempts (paid, refused, waiting for approval) with amounts, reasons and mock transaction hashes.get_policy· Returns the sandbox's spendctl.yaml: the agent's budgets, allowed hosts and approval rules.approve· Decides a pending approval in this sandbox, as the human approver would with `spendctl approve`. An approved payment completes when sandbox_pay is called again with the same approvalId; a denied one stays refused.
What "online" means: the server answered an MCP connection at the time of the check. It is not a guarantee of security, quality or continuous uptime. How we test: we open an MCP session and ask for the tool list, as an AI assistant would. We never run a tool and never send a key. Checked every few days. Method
Is this your server? Monitoring Pro: a check every 30 minutes and an email within the hour when it stops answering. Launch offer: $39.99 once, for life.
