SunLicense

SunLicense MCP server

Let your AI assistant run SunLicense, the license key service for software people sell (Minecraft plugins and mods, FiveM resources, Discord bots, desktop apps, games and tools): issue, suspend and revoke licenses, free a customer's machine, block a leaked key, look up customers, build automations, read license-check stats, and add a license check to your code.

It's SunLicense's official MCP server, hosted at:

https://api.sunlicense.com/mcp

Streamable HTTP with OAuth: the first time a tool runs, your assistant opens SunLicense in the browser, you sign in, untick any permission you don't want to give, and choose Connect. No API key to copy. Prefer a local server with a token (scripts, CI, no browser)? Use sunlicense mcp below.

MCP is included in every SunLicense plan: Free (50 tool calls a day), Lite (300) and Standard (3,000). Sign up free at app.sunlicense.com.

mcp-name: com.sunlicense/mcp

Connect

claude.ai, Claude Desktop and mobile: Settings → Connectors → Add custom connector → name SunLicense, URL https://api.sunlicense.com/mcp → Connect.

ChatGPT (a plan that allows custom MCP servers): chatgpt.com/plugins → Add → Add custom MCP server → URL as above, authentication OAuth, default advanced settings.

Claude Code:

claude mcp add --transport http sunlicense https://api.sunlicense.com/mcp

then /mcp → sunlicense → Authenticate. Or install the SunLicense plugin, which adds a skill for writing license checks too.

Cursor: add to ~/.cursor/mcp.json (or the project's .cursor/mcp.json), then Connect in Settings → MCP:

{
  "mcpServers": {
    "sunlicense": { "url": "https://api.sunlicense.com/mcp" }
  }
}

VS Code (GitHub Copilot agent mode):

code --add-mcp '{"name":"sunlicense","type":"http","url":"https://api.sunlicense.com/mcp"}'

Windsurf: add to ~/.codeium/windsurf/mcp_config.json:

{
  "mcpServers": {
    "sunlicense": { "serverUrl": "https://api.sunlicense.com/mcp" }
  }
}

Codex CLI:

codex mcp add sunlicense --url https://api.sunlicense.com/mcp
codex mcp login sunlicense

Cline, Gemini CLI and other clients: add a remote (Streamable HTTP) server with the URL above; any client that supports MCP OAuth works. It identifies itself with a Client ID Metadata Document or Dynamic Client Registration.

Local server: sunlicense mcp

The same tools run locally from the sunlicense CLI (macOS, Linux, Windows; npm installs a single binary). Create a personal access token in the dashboard (Settings → Access tokens) and add:

{
  "mcpServers": {
    "sunlicense": {
      "command": "npx",
      "args": ["-y", "@sunlicense/cli@latest", "mcp"],
      "env": { "SUNLICENSE_TOKEN": "slp_..." }
    }
  }
}

With the CLI installed (npm install -g @sunlicense/cli), sunlicense mcp install writes this for the assistants it finds. SUNLICENSE_API_KEY (an slk_ API key) also turns on test_validate, a real license check. Both servers share your organization's daily allowance.

What it can do

Try: "Issue a Pro license for [email protected]", "Why is AX8P-… failing?", "Someone posted my key on a forum, stop it", "How many license checks failed this week, and why?", "Add SunLicense to this Paper plugin".

Prompts: add_licensing (set up licensing in this project), investigate_license, block_leak, build_automation. Resources: SDK snippets (sunlicense://sdk/{language}) and the docs.

"Asks first" tools are marked destructive (destructiveHint), so assistants ask before running them. Every tool has a title and explicit read-only, destructive and open-world hints.

Safety and privacy

• The assistant acts as you: only what your role and the permissions you approved allow. Changes say "Issued by AI assistant (…)" on the license.
• License keys stay masked (AX8P-XXXX-XXXX-XXXX); a full key is shown only when you ask (reveal_license_key).
• SunLicense receives the tool calls only (the tool's name and arguments), never your prompts, chats or code.
• Disconnect any time: dashboard → Settings → Access tokens → Connected AI apps. Unused connections end after 30 days.

Details: Connect claude.ai, ChatGPT and other apps, sunlicense mcp, privacy policy.
