What is resend-email-mcp marketplace?

An MCP server that lets an AI agent work with Resend, an email-sending service. It covers email, domains, contacts, broadcasts, templates, webhooks, and delivery troubleshooting.

Use it to send and manage email, maintain domains and contacts, handle broadcasts and templates, manage webhooks, and investigate delivery problems.

It puts common email-management and delivery checks in one interface, including checks for DNS, bounces, and whether messages can be delivered.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Security

Grade A, and why

resend-email-mcp marketplace scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
