README

opn-mcp MCP server

An MCP server for opn.onl — the open-source, self-hostable URL shortener. It lets AI assistants (Claude Desktop, Cursor, etc.) shorten links, read analytics, generate QR codes, and manage links in natural language.

Works against the hosted service or your own self-hosted instance.

Setup

1. Get an API key

On your opn.onl instance, go to Settings → API Keys, create a key, and copy it (it starts with opn_ and is shown once).

2. Add the server to your MCP client

Claude Desktop — edit claude_desktop_config.json (~/Library/Application Support/Claude/ on macOS, %APPDATA%\Claude\ on Windows):

{
  "mcpServers": {
    "opn": {
      "command": "npx",
      "args": ["-y", "opn-mcp"],
      "env": {
        "OPN_API_KEY": "opn_your_key_here"
      }
    }
  }
}

Restart your client. That's it — it talks to the hosted API (https://l.opn.onl) by default.

Prefer to run from source? Swap the args for the GitHub build — same config: "args": ["-y", "github:ysalitrynskyi/opn-mcp"] (it builds on install).

Self-hosted instance

Point OPN_BASE_URL at your own instance's API host:

{
  "mcpServers": {
    "opn": {
      "command": "npx",
      "args": ["-y", "opn-mcp"],
      "env": {
        "OPN_API_KEY": "opn_your_key_here",
        "OPN_BASE_URL": "https://l.your-domain.com"
      }
    }
  }
}

Releasing

All three registries are owned by ysalitrynskyi (npm user, GitHub user, and the io.github.ysalitrynskyi MCP-registry namespace), so publishing must be done while signed in as that account.

Bump the version in three places and keep them identical: package.json, server.json (top-level and the packages[0].version), and SERVER_VERSION in src/server.ts.
Land it: commit to main and push. CI (.github/workflows/ci.yml) runs build + test — it does not publish.

Publish to npm (as npm user ysalitrynskyi):

npm login
npm publish        # prepublishOnly runs the build

Publish to the MCP registry (as GitHub user ysalitrynskyi):

mcp-publisher validate      # optional, offline check
mcp-publisher login github  # interactive browser OAuth
mcp-publisher publish

Smithery (smithery.yaml) and Glama (glama.json) track the npm/registry release automatically — no separate step.
