Mailercloud Email Verifier integration

Mailercloud Email Verifier checks whether email addresses can receive mail. An agent can verify up to 50 addresses in real time (deliverability status, risk level, delivery score, disposable, role and catch-all flags, typo suggestion), upload a CSV or TXT file of up to 100,000 addresses for bulk verification, follow its processing status, list uploaded files and download the results file. Every verification consumes one credit, unknown results included (active Mailercloud marketing subscribers get 250 free credits a month); 402 means credits ran out. Authentication is a separate Email Verifier API key (Email Verification, API Key in the Mailercloud app), sent as a Bearer token.

Say what should happen.
The workflow builds itself.

When this happens, do that in Mailercloud Email Verifier.Built from the 5 Mailercloud Email Verifier tools below, on the connection you add once.

What you can do with Mailercloud Email Verifier

Each of these is one operation on one endpoint, available both as a workflow step and as a tool an AI agent can call on its own. Nothing bundles several operations into one action, so what a run did stays readable afterwards.

Most endpoints run on the free plan. A few, mainly the ones that publish on your behalf, need a paid plan.

Verification file, 4 operations

download_verification_resultsDownload verification resultsGETDownloads the results file of a completed bulk verification as a stored file. Check get_verification_file_status first: results exist only once processing has finished.
get_verification_file_statusGet verification file statusGETGets the processing status of an uploaded verification file and its result counts (total_records, deliverable, invalid, risky). Call again until processing has finished.
list_verification_filesList verification filesPOSTLists uploaded verification files with paging (limit, offset), a name search and sorting (sort_by, sort_order). Read-only.
upload_verification_fileUpload verification filePOSTUploads a CSV or TXT file of email addresses (up to 10 MB and 100,000 addresses) for bulk verification, one credit per address. Returns file_id; follow progress with get_verification_file_status.

Email verification, 1 operation

verify_emailsVerify emailsPOSTVerifies 1 to 50 email addresses in real time (email and/or emails; duplicates removed): status, risk level, delivery score and flags per address. Each address costs one credit, unknown results included.

Use Mailercloud Email Verifier from Claude Code, Cursor or Codex

Connect Mailercloud Email Verifier in LiveContext, create an API key in Settings, then add the LiveContext MCP server to your client. Its Mailercloud Email Verifier operations become tools the client can call, next to every other integration you connected.

Claude Code

claude mcp add --transport http livecontext https://livecontext.ai/mcp --header "X-API-Key: YOUR_API_KEY"

Codex (~/.codex/config.toml)

[mcp_servers.livecontext]
url = "https://livecontext.ai/mcp"

[mcp_servers.livecontext.http_headers]
"X-API-Key" = "YOUR_API_KEY"

Cursor, Claude Desktop and other JSON configs

  "mcpServers": {
    "livecontext": {
      "type": "http",
      "url": "https://livecontext.ai/mcp",
      "headers": {
        "X-API-Key": "YOUR_API_KEY"
