Pre-payment checks for AI agents: x402 quotes, untrusted prompts and audit receipts.

Overview

AI-generated overview

Lets an AI assistant run pre-payment checks on x402 quotes, untrusted prompts and audit receipts before money moves.

What you can do
Varyntiq is a remote MCP endpoint for pre-payment checks aimed at AI agents. According to its description, it covers x402 quotes, untrusted prompts and audit receipts, so an assistant can validate a payment-related quote or prompt and obtain an audit record before paying. No individual tools are listed in the manifest, so the exact operations are not documented here.
When to use it
Consider it when an assistant handles x402 payment flows and you want a check on quotes or prompts, plus an audit receipt, before funds are committed. It is less relevant if your workflows do not involve agent payments or x402.
Requirements
A remote streamable HTTP endpoint; no local package is needed. Access requires a bearer client token sent in the Authorization header, obtained once from the provider's registration page. Network access to the endpoint is required.
Before you install
The Authorization bearer token is a secret and is shown only once at registration, so store it securely. The server concerns payments and pre-payment checks; confirm what it actually validates before relying on it to authorize spending. No tool list is published, so review its behavior before use.

Installation

In SourceWeft

  1. Open Varyntiq in the dashboard and add it to a workspace.
  2. Connect Authorization token credentials. They are stored privately and never shown on public pages.
  3. 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.mercadosclaro-eng%2Fpayguard/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

Other MCP clients

Add this to your client's mcpServers config.

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.
