Disposable Email Checker MCP

What Disposable Email Checker MCP does

Disposable Email Checker MCP MCP server provides one focused check for identifying temporary email usage. Its check_disposable_email tool accepts either an email address or a domain and checks whether it belongs to a known disposable-email provider. Examples named by the listing include mailinator.com and 10minutemail.com.

The result contains three fields: domain, which identifies the domain checked; disposable, which indicates whether the domain is classified as disposable; and source, which identifies the source associated with the result. This makes the server suitable for an agent that needs a structured classification rather than an informal explanation.

As a tool in the Security category, it can be used as one step in workflows that review or screen email addresses.

How it works

The server is available at the MCP endpoint https://disposable-email-mcp.ara-v1.workers.dev/mcp. An MCP client connects to that endpoint and invokes check_disposable_email with an email address or domain. The service compares the supplied value with its known disposable or temporary email provider data and returns the structured result.

Disposable Email Checker MCP MCP server usage is metered per call through Cloudflare x402. Payment is made in USDC on the Base network, so the calling setup needs to account for that payment model. The listing specifically states that an API key is not used.

Setup and configuration

Use the published MCP endpoint as the server address:

https://disposable-email-mcp.ara-v1.workers.dev/mcp

The listing does not provide a package, local installation command, configuration file, environment variables, or client-specific instructions. It also does not identify a required MCP client. Before using the tool in an automated workflow, confirm that the client can connect to the supplied endpoint and handle the Cloudflare x402 USDC-on-Base payment flow.

No API key is required according to the listing. Payment remains a requirement for metered calls, rather than a substitute credential described as an API key.

Tools and capabilities

• check_disposable_email: checks an email address or domain against known disposable or temporary email providers.
• Returns domain, disposable, and source.
• Accepts either a full email address or a domain.
• Uses per-call Cloudflare x402 metering with USDC on Base.

Limitations and notes

Disposable Email Checker MCP MCP server is documented as having one tool only. Its classification depends on the known-provider data available to the service, so the material does not support treating a non-disposable result as proof that an address is deliverable or belongs to a real person.

It also does not describe a local deployment option. Use the returned source field when the workflow needs to retain where the classification came from.
