Overview

AI-generated overview

Remote pay-per-call utility server offering 28 tools for email, domain, IP, document, web and on-chain checks, each billed in USDC via x402.

What you can do
  • Validate single or batch emails and screen sender domains for risk
  • Look up domains, IP addresses and URL metadata, or read pages as clean markdown
  • Convert PDFs and images to text, run OCR, extract invoice and form fields, convert file formats
  • Check timezones, business days, public holidays and ECB currency rates
  • Inspect tokens, estimate gas, decode transactions, resolve ENS names and read wallet balances
  • Audit x402 paid endpoints and run invoice intake triage
When to use it
Useful when an assistant needs small, self-contained lookups or document parsing without managing its own API keys: lead and list cleaning, fraud and phishing triage, RAG ingestion of PDFs and pages, deadline and currency math, or pre-swap and payment checks on EVM chains.
Requirements
Remote streamable HTTP endpoint; no account, environment variables or headers declared. Every call is paid in USDC on Base through x402, so the client must be able to sign and settle payments and pass them in params._meta["x402/payment"]. Network access to the endpoint and to the public sources it queries.
Before you install
Every tool costs money per call (roughly $0.001 to $0.012 USDC), so automated or looping use spends funds; batch tools are cheaper per item. A wallet with USDC on Base is required to pay. Submitted URLs, emails, IPs and documents are sent to a third-party service. Outputs such as risk scores, deliverable guesses and invoice verdicts are heuristics, not verification.

Installation

In SourceWeft

  1. Open Agent Tools 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/me.crowdspark.agents%2Fagent-tools/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

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.
