Audit a domain email deliverability via Apify: SPF, DKIM, DMARC, MX, blacklist, catch-all, age.
If you already use MCP, the mcp mcp server is the piece that lets your assistant work with it directly. Audit a domain email deliverability via Apify: SPF, DKIM, DMARC, MX, blacklist, catch-all, age.
An MCP server that exposes the Mamba Labs Domain Deliverability Checker as a single tool. Install one package and give your MCP client a way to audit any domain's email deliverability and DNS health, wrapping the Mamba Labs actor on Apify and returning Clay-ready flat JSON.
The toolset is worth reading before you wire it up, because it tells you what the integration is really for:
check_domain_deliverability — audit a domain's SPF, DKIM, DMARC, MX, mail provider, DNS blacklist status, catch-all, domain age, and a 0 to 100 deliverability scoreActor — Immutable Actor IDConfiguration is passed through the environment: APIFY_TOKEN. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client. The configuration blocks on this page cover the common clients.
Among the team communication options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. MCP's toolset — check_domain_deliverability, Actor — is a fair guide to whether it matches your workflow. It is maintained by com.mambabuilt; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
