Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Trigger events, query channels, and manage realtime messaging on Pusher Channels.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.
Pick the AI app you use, then copy the settings.
PUSHER_APP_ID, PUSHER_KEY, PUSHER_SECRET, PUSHER_CLUSTERValues marked secret are keys to your account. Never share them or paste them into a chat.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
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.
You need to fill in: PUSHER_APP_ID, PUSHER_KEY, PUSHER_SECRET, PUSHER_CLUSTER
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 –, and the latest version (1.0.3) reached the registry 9 months ago.

An MCP (Model Context Protocol) server that gives AI agents the ability to send realtime messages, query channels, and manage users through Pusher Channels.
| Tool | Description |
|---|---|
trigger_event | Send an event to one or more channels |
trigger_batch_events | Send up to 10 events in a single API call |
list_channels | List active channels with optional prefix filter |
get_channel_info | Get subscription/user count for a channel |
get_presence_users | List users connected to a presence channel |
authorize_channel | Generate auth tokens for private/presence channels |
terminate_user_connections | Disconnect all connections for a user |
npm install -g @crashbytes/pusher-mcp-server
Or clone and build from source:
git clone https://github.com/CrashBytes/pusher-mcp-server.git
cd pusher-mcp-server npm install npm run build
You need four environment variables from your Pusher dashboard:
| Variable | Description |
|---|---|
PUSHER_APP_ID | Your Pusher app ID |
PUSHER_KEY | Your Pusher app key |
PUSHER_SECRET | Your Pusher app secret |
PUSHER_CLUSTER | Your Pusher cluster (e.g. us2, eu, ap1) |
Add the following to your Claude Desktop config file:
macOS: ~/Library/Application Support/Claude/claude_desktop_config.json Windows: %APPDATA%\Claude\claude_desktop_config.json
{
"mcpServers": { "pusher": { "command": "node", "args": ["/path/to/pusher-mcp-server/build/index.js"], "env": { "PUSHER_APP_ID": "your_app_id", "PUSHER_KEY": "your_app_key", "PUSHER_SECRET": "your_app_secret", "PUSHER_CLUSTER": "us2" } } } }
If installed globally via npm:
{
"mcpServers": { "pusher": { "command": "pusher-mcp-server", "env": { "PUSHER_APP_ID": "your_app_id", "PUSHER_KEY": "your_app_key", "PUSHER_SECRET": "your_app_secret", "PUSHER_CLUSTER": "us2" } } } }
claude mcp add pusher -- node /path/to/pusher-mcp-server/build/index.js
Set the environment variables in your shell before running, or configure them in your Claude Code MCP settings.
Once configured, you can ask Claude things like:
npm install
npm run dev # Run with tsx (hot reload) npm run build # Compile TypeScript npm run type-check # Check types without emitting
