Overview

AI-generated overview

Pay-per-call remote MCP server returning compact JSON reports on drugs, companies, SEC filings, domains, web pages, US addresses, weather and emails, billed…

What you can do
  • Look up drug data: RxNorm drug cards, FDA shortages and recalls, NDC conversion and product records, CMS NADAC prices
  • Profile companies and filings: Wikidata and GLEIF company cards, SEC EDGAR profiles and recent filings
  • Check domains and email: RDAP/WHOIS, DNS records, SPF/DMARC/MTA-STS posture, live URL and header checks, email address verification
  • Geocode US addresses and fetch NWS forecasts and alerts
  • Inspect x402 payments: preflight a paid endpoint's price and decode a payment receipt
  • List all tools, prices and payment networks via the free catalog tool
When to use it
Useful when an assistant needs authoritative, citable facts about a drug, company, domain, address or email address without building integrations to each public source, and when per-call USDC billing is acceptable.
Requirements
Remote streamable HTTP endpoint; no local install, accounts or API keys declared. Each paid call requires an x402 v2 USDC payment on Base, Polygon, Arbitrum, Avalanche or Sei, supplied as a signed payment payload in the request metadata. Network access to the endpoint and its upstream public data sources.
Before you install
Every tool except the catalog costs USDC per call, so automated or looping use spends real money; failed or empty-result calls are stated not to be charged. Payment payloads and wallet signing are involved, and the server returns a payTo address and accepted networks. Lookups send the queried drug names, domains, addresses and email addresses to the server and its upstream sources.

Installation

In SourceWeft

  1. Open Kit Rx 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/com.kit-rx.api%2Fkitrx/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
