README

Alphorn MCP Server

MCP server for Alphorn, the open-source notification router. It gives AI agents (Claude Code, Claude Desktop, Cursor, Codex, and any other MCP client) a send_notification tool, so an agent can tell you when a task finishes, fails, or needs your decision, on whatever channel you configured in Alphorn: Slack, Telegram, Discord, email, SMS, push, and more.

Works with the hosted service at app.alphorn.dev and with self-hosted Alphorn.

Setup

Create a webhook in Alphorn and copy its Endpoint URL, plus its API key if you switched on Require API key (docs).
Add the server to your MCP client with two environment variables:

Variable	Value
`ALPHORN_WEBHOOK_URL`	Endpoint URL, e.g. `https://app.alphorn.dev/n/V1StGXR8_Z5jdHi6B-myT`
`ALPHORN_API_KEY`	Webhook API key (`alp_...`). Leave unset if the webhook does not require one.

Claude Code

claude mcp add alphorn -s user \
  -e ALPHORN_WEBHOOK_URL=https://app.alphorn.dev/n/V1StGXR8_Z5jdHi6B-myT \
  -e ALPHORN_API_KEY=alp_... \
  -- npx -y @alphorn/mcp

Claude Desktop (one-click bundle)

Download alphorn.mcpb from the latest release and open it. Claude Desktop asks for the Endpoint URL and API key.

Claude Desktop, Cursor, and other JSON-configured clients

Add to claude_desktop_config.json, ~/.cursor/mcp.json, or your client's MCP config:

{
  "mcpServers": {
    "alphorn": {
      "command": "npx",
      "args": ["-y", "@alphorn/mcp"],
      "env": {
        "ALPHORN_WEBHOOK_URL": "https://app.alphorn.dev/n/V1StGXR8_Z5jdHi6B-myT",
        "ALPHORN_API_KEY": "alp_..."
      }
    }
  }
}

OpenAI Codex CLI

# ~/.codex/config.toml
[mcp_servers.alphorn]
command = "npx"
args = ["-y", "@alphorn/mcp"]
env = { ALPHORN_WEBHOOK_URL = "https://app.alphorn.dev/n/V1StGXR8_Z5jdHi6B-myT", ALPHORN_API_KEY = "alp_..." }

Tool

`send_notification`

Argument	Type	Required	Description
`message`	string	yes	What happened and what the agent needs from you (max 4,000 characters)
`title`	string	no	Short title, e.g. `my-app - tests passing` (max 200 characters)
`priority`	integer 1-5	no	2 = finished, 3 = needs input, 4 = blocked or failed, 5 = urgent
`tags`	string[]	no	Tags to filter and route on in Alphorn, e.g. `["ai-agent", "completed"]`

The tool wraps Alphorn's send endpoint. For direct HTTP use, see the API reference and the OpenAPI 3.1 specification.

Use Alphorn's filters to decide where each notification goes, for example SMS only for priority 4 and above.

Development

pnpm install
pnpm test   # builds, then runs the tests against a local fake endpoint

Releasing

Bump version in package.json, server.json (both fields), manifest.json, and VERSION in src/server.ts.
npm publish --access public
Push a v<version> tag (or run the Publish to MCP Registry workflow): it publishes server.json to the MCP Registry via GitHub OIDC
pnpm bundle, then attach alphorn.mcpb to a GitHub release
