Overview

AI-generated overview

Remote MCP server offering 38 pay-per-call tools for web extraction, crypto and on-chain data, DNS, geo and package lookups, billed in USDC/USDT on Base.

What you can do
Extract and convert web content: clean page extraction, HTML to Markdown, crawling, sitemaps, metadata, URL health checks, PDF text, RSS and YouTube transcripts, plus web and news search, Hacker News, Reddit, Wikipedia and arXiv lookups, and SEO audits, email validation, DNS/WHOIS/RDAP and IP geolocation, and npm/PyPI package intelligence and GitHub repo summaries, and crypto and on-chain data: token prices, OHLCV, DEX prices, spreads, gas fees, wallet and ERC-20 balances, transaction status, ENS, DeFi yields and TVL, fear and greed, and fiat currency conversion.
When to use it
Useful when an assistant needs many small, unrelated data lookups (web pages, crypto markets, on-chain state, domains, packages) without managing separate API keys, and when per-call crypto payment is acceptable.
Requirements
A remote streamable HTTP endpoint; no API key or signup. Each paid call is settled in USDC or USDT on Base via x402, so a funded wallet able to sign x402 payments is needed; three free calls per wallet are offered.
Before you install
Most tools are paid per call in USDC/USDT on Base, so usage spends real funds; best_price charges a commission on the savings it finds. Tools fetch arbitrary public URLs and send queries to third-party data sources. No authentication is declared, so payment is tied to the calling wallet.

Installation

In SourceWeft

  1. Open Agent Margin Router 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.AgentMarginRouter%2Fagent-margin-router/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
