Common questions

Is Outreach Deliverability MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.2) reached the registry 4 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

Outreach Deliverability MCP

The channel-safety layer for cold outreach. Volume discipline, sender setup, spam auditing — so good messages actually arrive.

Disclaimer. Platform limits and filtering behavior change frequently; values are conservative practitioner ranges as of last verification, not platform guarantees. Legal notes (CAN-SPAM / GDPR / PECR / CASL) are orientation, not legal advice.

Why This Exists

Most outbound fails before the copy is ever read. Burned domains, throttled LinkedIn accounts, and spam-foldered sends kill campaigns that any message audit would have passed. AI agents make this worse: they can generate 500 perfect emails an hour, and sending them is exactly how you lose the domain.

This MCP is the layer that keeps the channel alive. It does NOT send anything — it returns rules, checklists, and audits that an agent consults BEFORE and DURING a campaign.

The core diagnostic it encodes: deliverability problems masquerade as copy problems. A 1% reply rate usually isn't a bad hook — it's a foldered send. Fix order: infrastructure → list → message.

6 Tools

Tool	What it returns
`get_channel_rules`	Safe daily volumes, account setup, warmup protocol, kill signals, personalization floor, and legal basics per channel: email, LinkedIn, Instagram DM, X DM
`get_sender_setup_checklist`	The 10-step cold-email infrastructure checklist: lookalike domains, SPF, DKIM, DMARC, mailboxes, warmup, list verification, tracking, compliance, monitoring
`audit_spam_triggers`	Copy audit: 30+ flagged phrases, all-caps, exclamations, link count, attachments, money symbols, fake Re:/Fwd: — with a 0-100 risk score
`interpret_benchmark`	Healthy/warning ranges for open rate, reply rate, bounce rate, LinkedIn acceptance, DM reply — with an optional direct read of your observed value
`diagnose_campaign`	Given your observed metrics, names the failure layer (infrastructure vs list vs message) and the fix order
`get_full_pack`	The complete library as one payload for full agent context

Sample Use

// Campaign feels dead. Copy problem or channel problem?

mcp.call("diagnose_campaign", { channel: "email", open_rate: 31, reply_rate: 0.8, bounce_rate: 4.2 }); // Returns: failure layer = LIST. Bounce 4.2% > 3% is actively damaging the // domain; open 31% says sends are being foldered. Fix infrastructure and // list BEFORE touching the copy.

mcp.call("audit_spam_triggers", { text: "URGENT: Don't miss this LIMITED TIME offer!!! Click here..." }); // Returns: HIGH RISK, phrase + structural hits itemized.

Works With

Pair with outbound-engine-mcp: that one makes the message worth sending; this one makes sure it lands.
