Common questions

Is pingwa 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?

You need to fill in: PINGWA_KEY

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.4.1) 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. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Vexa, emailmd, MCP WhatsApp Cloud

README from the maker

Open the README

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.

pingwa (client)

WhatsApp notifications for AI agents and scripts with zero setup — no Meta account, no templates, no dashboard: text "join", get an API key, curl → WhatsApp in 60s. Two-way human-in-the-loop: your agent asks, you tap a button to answer. From your terminal or an MCP client.

This is the open-source (MIT) pingwa client: a CLI, a tiny HTTP client, and an MCP server. It talks to a pingwa backend (the hosted service at https://pingwa.dev, or your own). The backend is separate and private; this client is not.

Install & use

No install needed with uv:

export PINGWA_KEY=pw_your_key          # get one: send "join" on WhatsApp to the service number

uvx pingwa send "build finished ✅" # notify your own phone echo "deploy done" | uvx pingwa send - # from stdin uvx pingwa ask "Deploy to prod?" --button yes --button no # wait for a reply from your phone uvx pingwa replies # pull messages your phone sent back (out-of-band steering) uvx pingwa me # plan / quota / reply-window uvx pingwa keys # list active API keys (up to 10 named keys per number) uvx pingwa keys revoke ci # revoke one by name (or reply 'revoke ci' on WhatsApp) uvx pingwa upgrade # get a Stripe link to go Pro (no password needed) uvx pingwa send "x" --json # raw JSON response

AI agents: don't ask your human to copy-paste a key — drive the registration yourself (POST /v1/registrations; full recipe in llms.txt). The human only taps one WhatsApp link; the key is claimed by you and never travels through the chat. Works for existing accounts too — it mints an additional named key.

Exit codes: 0 ok · 2 missing key · 3 quota exceeded · 1 other. Override the backend with PINGWA_BASE_URL or --base-url.

Webhooks

Prefer PUSH over polling replies? Register HTTPS endpoints and pingwa POSTs every inbound WhatsApp message to them:

uvx pingwa webhooks                                   # list your webhooks

uvx pingwa webhooks add https://your-host/pingwa-hook # returns a signing SECRET, shown ONCE uvx pingwa webhooks rm https://your-host/pingwa-hook # by id, or by exact url

add prints a whsec_... secret once — store it now; it never appears again. Each delivery carries an X-Pingwa-Signature: sha256= header (an HMAC-SHA256 of the raw body under that secret) — verify it and reject anything that fails. Full verification recipe and payload shape: llms.txt. Up to 5 active webhooks per account; to rotate a secret, rm then add again.

MCP server

Same tools on stdio and remote: notify(text), ask(text, buttons?, timeout?), check_replies(since?, wait?), check_status(), upgrade().

Local (stdio) — for Claude Desktop / Claude Code:

"mcpServers": { "pingwa": { "command": "uvx", "args": ["pingwa", "mcp"], "env": { "PINGWA_KEY": "pw_your_key" } } } }

Remote (Streamable HTTP, no install):

"mcpServers": { "pingwa": { "url": "https://pingwa.dev/mcp", "headers": { "Authorization": "Bearer pw_your_key" } } } }

Every error carries an action hint, so an agent knows what to do next.

What it sends

Only your message text and your key, to the pingwa backend you point it at — over HTTPS. Nothing else. The recipient is always your own phone (there is no "to" field). See the service's /privacy.

License

MIT — see LICENSE in the repository root. It covers this client package only (src/pingwa/client/); the pingwa server is separate, private, and not published. See NOTICE for the exact boundary.
