Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 3 of 3 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.
The registry does not list a required key, though some servers ask you to sign in on first use.
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).
The GitHub repo last changed 9 days ago, and the latest version (1.2.3) reached the registry 10 days ago.

Reverse engineer anything from your terminal or agent with one CLI and MCP server.
A powerful toolkit for coding, providing semantic retrieval and editing capabilities.
Copied from the maker’s repo as written. PopNx MCP has not reviewed or endorsed it. HTML, images and scripts are removed. Links lead off this site.
Official Model Context Protocol server for Notify.
Use this in Cursor, Claude Code, or other MCP hosts when a coding agent should call Notify tools directly. For app/CI code, prefer the notifycx SDK or plain fetch.
Already have a key:
{
"mcpServers": { "notify": { "command": "npx", "args": ["-y", "notifycx-mcp"], "env": { "NOTIFY_API_KEY": "nk_..." } } } }
No key yet: omit NOTIFY_API_KEY, call bootstrap_start → user pastes email OTP → bootstrap_confirm → put the returned api_key into MCP env. See agent bootstrap docs.
Never paste API key secrets into chat logs.
| Tool | When to use |
|---|---|
bootstrap_start / bootstrap_confirm | Sign up or recover without the dashboard (no API key required) |
send_email | Production transactional send (verified from) |
send_test_email | Non-delivering API rehearsal |
add_domain | Add domain + structured dnsRecords (type/name/value) for the user to publish at their host |
check_domain | Poll verification after DNS is configured |
list_domains / get_domain | Domain status + dnsRecords |
list_webhooks / create_webhook / update_webhook / delete_webhook / get_webhook / test_webhook | Webhook setup (Pro+) |
list_email_logs | Recent delivery logs |
get_usage | Quota / account_verified |
list_api_keys / create_api_key / regenerate_api_key / delete_api_key | Manage keys |
create_billing_checkout | Stripe Checkout URL for Pro/Scale |
Typical setup path: bootstrap → add_domain → user publishes dnsRecords → check_domain → send_email.
Free: 1,000 emails/mo. Pro: $10 / 10,000. Scale: $50 / 100,000.
After npm publish for notifycx-mcp, register the release with the MCP Registry: from the mcp/ directory, run mcp-publisher login github (as a notifycx org member), then mcp-publisher publish.
