Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified that this server's namespace belongs to x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev, which also runs its endpoint. That identifies the publisher; it does not make the server's tools safe.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

Pay-per-call remote MCP server for email address checks, URL uptime pings and web page to markdown reading.

What you can do: Validate single email addresses or batches of up to 25 (syntax, MX records, disposable and role addresses)
Ping one URL or up to 10 URLs at once for status, latency, redirects and TLS from a Cloudflare edge
Read a web page and return clean markdown with title and character count
Return the exact paid request for each input, or the data itself when a prepaid key is used
When to use it: Useful when an assistant needs to vet email addresses before sending or importing, check whether endpoints are up, or pull a web page into readable text for summarization and analysis.
Requirements: Remote streamable HTTP endpoint; no account, API key or environment variables declared. Paid calls use x402 or MPP payment per request, or a prepaid key bought separately. Network access to the endpoint is required.

Before you install

Calls cost money per request (for example $0.01 per email check, $0.25 per batch of 25, $0.005 per page read), so automated loops can spend funds. A prepaid key is a credential to protect. Submitted email addresses and URLs are sent to the provider's service.

Installation

In SourceWeft

Open P0: email check, uptime, web reader in the dashboard and add it to a workspace.
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/dev.workers.x402-bazaar-rank-worker.x402-bazaar-rank%2Femail-uptime-web-reader/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

Use when you must check an email address before sending, signing up a user or adding a lead: syntax (IDN-aware), MX records with A/AAAA fallback, null MX, and disposable, role (info@, sales@). Returns the paid x402 request for your input (GET /v1/email/verify, $0.01 per call; schema linked). Call that URL with an x402 or MPP client to get the data. Bad input is refused before any charge. Checks one mailbox; for a list use check_email_batch. With an access key (Authorization: Bearer p0k_..., buy at https://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/keys/buy?usd=5) the tool pays the call itself, returns the data and deducts the price. First call each day returns the data itself, free; later calls return the paid request.
