Overview

AI-generated overview

Ox402 Utils is a remote MCP server offering many small pay-per-call utilities — web research, screenshots, OCR, speech, security recon, prices and more — billed

What you can do
Research and web: search, scrape pages, extract structured data, build research briefs and citations, fetch OpenAPI and GraphQL endpoints, archive pages, convert HTML to markdown, check robots and sitemaps, test link health, preview links and generate QR codes. Documents and media: extract PDF text, run OCR, convert markdown to PDF, build PDF invoices, merge and compress PDFs, download videos, convert video to MP3, optimize and compress images, and capture full-page or mobile screenshots. Speech: transcribe audio with Whisper and synthesize speech with a neural text-to-speech model, including listing available voices. Security and recon: check security headers, CORS and cookie flags, run DNS
When to use it
Use it when an assistant needs capabilities its own sandbox lacks — opening a browser for screenshots, running a GPU speech model, scanning a host, or auditing a site's TLS — and you are willing to pay small per-call fees in USDC. The free trial of 10 calls per IP on free-tier tools is enough to evaluate it.
Requirements
A remote MCP endpoint reached over HTTP; no account or API key is needed. Paid tools require an x402 client that can pay USDC on Base mainnet and resend the request with the X-Payment header. The published endpoint is a rotating tunnel URL, so the live address must be looked up before connecting.
Before you install
Paid tools spend real money: each call is settled in USDC on Base mainnet, so an agent that calls tools freely can incur charges. Payments go to the payee address stated in the README. The endpoint is a rotating tunnel, so the address can change or disappear. Requests, including URLs and content submitted to tools, are sent to a third-party server. Some tools run code or scan hosts, so only target systems you are authorized to test.

Installation

In SourceWeft

  1. Open Ox402 Utils 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.Hasned-spec%2Fox402-utils/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

README

ox402-utils

94 capability APIs an AI agent can't run in its own sandbox — paid per call via x402 (USDC on Base). Web research, security recon, neural text-to-speech (Kokoro-82M), speech, document + media conversion, full-page screenshots, SSL/breach audits, SQL sandboxes, embeddings, and more. No accounts, no API keys, no subscription. Free trial: 10 calls/IP on tier=free tools.

[Hasned-spec/ox402-utils MCP server]

Live site: the current tunnel URL is published in api.txt and /.well-known/x402 on this repo's served docs, and rotates periodically — fetch api.txt for the live endpoint. MCP server: /mcp402/ · Catalog: /x402/catalog · Machine-readable: /llms.txt

Why this exists

An AI agent's sandbox can't open a browser, run a GPU TTS model, scan a host for open ports, or audit a site's TLS. ox402 does those for it — and bills per call in USDC. No signup, no API key, no monthly minimum. Every call is authorized by an on-chain micropayment (x402): hit the endpoint, get a 402 challenge, pay the exact amount, retry with the X-Payment header.

Free trial: 10 calls/IP on tier=free tools. Paid-tier tools always require x402 USDC.

Use it in 30 seconds (curl)

bash
# Free trial (10 calls/IP): no payment neededcurl -X POST http://129.213.128.185/x402/trial/search \  -H 'Content-Type: application/json' \  -d '{"query":"x402 protocol","count":3}'
# Paid tier: POST -> 402 challenge -> pay -> retry with X-Payment headercurl -i http://129.213.128.185/x402/paid/search \  -H 'Content-Type: application/json' \  -d '{"query":"x402 protocol","count":3}'

The 402 response carries a PAYMENT-REQUIRED challenge with the exact USDC amount and the payTo address. Pay on Base, then repeat the request with the signed payment in the X-Payment header (any x402 client: the Coinbase x402 fetch wrapper, or your own signer). Verified + settled via our self-hosted facilitator (melonask/facilitator) on Base mainnet.

json
{  "mcpServers": {    "ox402-utils": { "url": "http://129.213.128.185/mcp402/" }  }}

tools/list is free and returns all 94 tools (compact ~1.6k-token menu; full schemas on demand). tools/call returns the payment instructions when unpaid. Drop it into Claude Desktop, Cursor, or any MCP framework and the agent can pay-to-use every tool.

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declaredRequired10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
