ldm-inbox-check-mcp
MCP server for Inbox Check — programmatic email deliverability testing across Gmail, Outlook, Yahoo, Mail.ru and Yandex. Plug it into Claude Desktop, Cursor, or any other MCP-compatible AI client.
What it does
Exposes 5 tools that wrap the Inbox Check REST API:
| Tool | Description |
|---|---|
inbox_check_create | Create a placement test; returns seed addresses to send your email to. |
inbox_check_status | Get per-provider placement, SPF/DKIM/DMARC, screenshots. |
inbox_check_list | List recent tests with cursor pagination. |
inbox_check_delete | Delete a test and its screenshots. |
inbox_check_me | Inspect API key metadata, features, quota usage. |
Install
npx ldm-inbox-check-mcp
No global install needed — Claude Desktop / Cursor will npx-run it on
demand.
Get an API key
- Go to https://check.live-direct-marketing.online/docs.
- Contact the operator for a key (self-service issuance coming later).
- Copy the
icp_live_...string — it’s shown exactly once.
Configure your MCP client
Claude Desktop
Edit ~/Library/Application Support/Claude/claude_desktop_config.json
(macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):
{
"mcpServers": {
"inbox-check": {
"command": "npx",
"args": ["-y", "ldm-inbox-check-mcp"],
"env": {
"INBOX_CHECK_API_KEY": "icp_live_xxxxxxxxxxxxxxxxxxxxxxxx"
}
}
}
}
Cursor
~/.cursor/mcp.json:
{
"mcpServers": {
"inbox-check": {
"command": "npx",
"args": ["-y", "ldm-inbox-check-mcp"],
"env": { "INBOX_CHECK_API_KEY": "icp_live_..." }
}
}
}
Custom agents (Agent SDK, LangChain, etc.)
Run the server manually and pipe stdio, or use the underlying REST API directly — see https://check.live-direct-marketing.online/docs.
Environment variables
| Variable | Required | Default |
|---|---|---|
INBOX_CHECK_API_KEY | yes | — |
INBOX_CHECK_BASE_URL | no | https://check.live-direct-marketing.online |
Override the base URL only for self-hosted deployments or testing.
Example prompt
“Use inbox-check to create a test against Gmail and Outlook, then wait 60 seconds and tell me where the email landed.”
The agent will call inbox_check_create, show you the seed addresses to
send to, and (after you send) call inbox_check_status to report
placements.
