ntfy-mcp-server sends, manages, and replays ntfy push notifications via the Model Context Protocol (MCP). It wraps the ntfy HTTP API into four tools and one resource, supporting both STDIO and Streamable HTTP transports. Built for developers integrating push notification workflows into AI agents or MCP-enabled applications.
Add the server to your MCP client’s config file using bunx ntfy-mcp-server@latest or a Docker image, then set the required environment variable NTFY_DEFAULT_TOPIC. For authentication, set a bearer token or basic‑auth credentials. Public ntfy.sh works without an account. The server runs via STDIO by default; for HTTP, set MCP_TRANSPORT_TYPE=http and start with bun run start:http.
Bun v1.3.11 or higher (or Node.js v24+). The server is written in TypeScript.
Use the `NTFY_SERVERS` environment variable – a JSON array of `{ baseUrl, authToken? | authUsername?+authPassword? }` entries. The first entry becomes the default. Per‑call `base_url` overrides only forward auth when matching a registered server.
Yes. The public ntfy.sh server works out of the box without any credentials. For protected topics, generate a bearer token at `ntfy.sh/account` or use basic auth.
By default it uses in‑memory storage, but the underlying framework supports swappable storage backends: filesystem, Supabase, or Cloudflare KV/R2/D1.
STDIO (default) and Streamable HTTP. For HTTP, set `MCP_TRANSPORT_TYPE=http` and configure host/port. Session mode can be `stateless`, `stateful`, or `auto`.
