Overview

AI-generated overview

Remote MCP server that vets x402 (HTTP 402) paid APIs before payment and finds cheaper working alternatives, plus paid web/PDF reading.

What you can do
  • Check a paid x402 API before paying: uptime, real price versus its listing, and cheaper alternatives
  • Run a preflight GO / CAUTION / STOP verdict on a service URL and its PAYMENT-REQUIRED value or price and payee
  • Find the cheapest working paid APIs for a described need, ranked by live price, uptime and speed
  • Fetch a public web page or PDF and return clean Markdown with title, author, date, JSON-LD and links
  • Read a public page's metadata: title, description, canonical URL, language, site name, author, publish date and image
When to use it
Useful when an assistant is about to pay an x402 API and you want a sanity check on price and availability first, or when you need to compare paid agent APIs for a task. Also handy for turning public pages and PDFs into clean Markdown or metadata.
Requirements
A remote streamable HTTP endpoint; no local install, account, API key or header is declared. Some tools are metered: 20 free calls per day per client for the cheapest-service finder, then paid per call via x402 (USDC on Base); the web reader and metadata tools are paid per call via x402.
Before you install
Several tools cost money per call through x402 payments in USDC on Base, so an assistant can spend funds; the free checks are the ones to run before paying. The service finder is limited to 20 free calls per day per client. You pass a service URL and its PAYMENT-REQUIRED value or payee details to the server, and requested pages are fetched by a third party.

Installation

In SourceWeft

  1. Open Agent Deals 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.gmahar82-stack%2Fagent-deals/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.
