Overview

AI-generated overview

Remote x402 preflight server that lets an assistant check an agent's payment intent or exact action authority before it executes.

What you can do
Read free metadata about the FOXIFY preflight tools and what they cover, including pricing and purpose, before using them. Run a paid payment preflight that checks mandate, amount, destination, merchant, expiry and replay risk before an autonomous payment executes. Run a paid exact-action authority preflight for consequential tool calls, binding subject, tool, operation, target, canonical parameters, authority lifetime, retries and postcondition requirements.
When to use it
Use it when an agent is about to make an autonomous payment or take a consequential tool action and you want a structured check of mandate, limits, destination, expiry, replay risk or exact action authority first. The free info tool helps you decide whether the paid checks are worth it.
Requirements
A remote streamable HTTP endpoint; no local package, environment variables or headers are declared. The two verification tools are paid: $0.05 USDC on Base for payment preflight and $0.25 USDC on Base for action preflight, so a funded Base wallet able to pay via x402 is needed.
Before you install
Both verification tools cost real money in USDC on Base per call, so repeated use spends funds. The server receives payment intent and action details, including amounts, destinations, merchants, tools, targets and parameters, which may be sensitive. It is a preflight check only; it does not itself execute or block the payment or action.

Installation

In SourceWeft

  1. Open FOXIFY Agent Authority + Payment Preflight in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.speeedy10%2Ffoxify-x402-agent-commerce-payment-preflight/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

83% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
