# WarmySender plugin
**Run your outreach on autopilot with AI agents.**
Build, launch and manage cold email, LinkedIn, Instagram and WhatsApp campaigns, verify
email addresses, tune warmup and pull B2B leads — all in plain language, from the agent you
already use.
Your agent never sends a message, DM or invite itself, and it can never raise a limit.
Creating or launching a campaign simply writes it and hands it to WarmySender's scheduler,
which paces every email, LinkedIn, Instagram and WhatsApp action inside safe caps and the
gradual ramp — no matter whether a person or an agent started it. Connecting and
disconnecting accounts stays in the app.
## What the plugin ships
| Component | Contents |
|---|---|
| MCP server | `https://warmysender.com/mcp` — 75 tools across campaigns, prospects, warmup, mailboxes, LinkedIn, Instagram, WhatsApp, email verification, tracking domains, suppressions and B2B leads |
| Skills | `launch-cold-email-campaign`, `run-multichannel-outreach`, `protect-email-deliverability` |
## Install
### Cursor
Install **WarmySender** from the [Cursor Marketplace](https://cursor.com/marketplace), then
paste your WarmySender API key when Cursor asks for it (**Plugins → Configure**).
Create the key in WarmySender under **Settings → API Keys**.
### Claude Code
```bash
claude plugin install warmysender
```
### Any other MCP client
Point it at `https://warmysender.com/mcp` (streamable HTTP). Two ways to authenticate:
- **Sign in through the browser** — the server supports OAuth 2.1 with PKCE and dynamic
client registration, so clients that speak it need no key at all.
- **API key** — send `Authorization: Bearer <your key>` with each request.

## Network and credentials
This plugin calls exactly one endpoint: `https://warmysender.com/mcp`. It reads no files
and runs no local code. The only credential it uses is the WarmySender API key you supply,
which is stored by your client — never in this repository.
