get_cancel_steps — How to cancel one subscription
Advertised by the server during the last successful anonymous check.
Advertised read-onlyOpen-world

How to cancel one subscription. For requests like "how do I cancel Netflix?", "cancel my Planet Fitness membership", "how do I leave Sky?", "cancel my PureGym", "what's the cheapest way to keep Spotify?", "stop my Audible". Returns the official page, steps, catches and a cheaper option. UK answers add region ("UK") and uk_rules; a US-only service asked about from the UK has region "US only".

identify_charge — Which subscription is this charge?
Advertised by the server during the last successful anonymous check.
Advertised read-onlyOpen-world

Which subscription is this charge? For requests like "what is this APPLE.COM/BILL charge?", "I see AMZN Digital on my statement", "what is DD *DOORDASH DASHPASS?". Returns the likely service, or for Apple, Amazon, Google and Microsoft the few it could be and where to check, or match: purchase when it looks like a one-off order (marketplace, a ride, a restaurant through a delivery app). Then call get_cancel_steps.

get_cancel_reminder — Calendar reminder for the last safe day to cancel

Returns a calendar file (.ics) with an all-day event on the cancel-by day, the steps and the official link, with alerts at 9am the day before and 9am on the day. Nothing is stored. get_cancel_steps gives this link as add_to_calendar whenever renews_on is given and the day hasn't passed.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http cancel-my-sub-mcp https://goodturn-mcp.pages.dev/cancelmysub/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add cancel-my-sub-mcp --url https://goodturn-mcp.pages.dev/cancelmysub/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable cancel-my-sub-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "cancel-my-sub-mcp": {
      "url": "https://goodturn-mcp.pages.dev/cancelmysub/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
Cline configuration
{
  "mcpServers": {
    "cancel-my-sub-mcp": {
      "type": "streamableHttp",

      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start cancel-my-sub-mcp and inspect its tools.
VS Code configuration
{
  "servers": {
    "cancel-my-sub-mcp": {
      "type": "http",
      "url": "https://goodturn-mcp.pages.dev/cancelmysub/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http cancel-my-sub-mcp https://goodturn-mcp.pages.dev/cancelmysub/mcp

Claude Desktop

Open Claude Settings > Connectors > Add custom connector, enter this server URL and enable it for the conversation. This is a manual remote-connector handoff, not a desktop JSON configuration.
Claude Desktop configuration
https://goodturn-mcp.pages.dev/cancelmysub/mcp

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
Windsurf configuration
{
  "mcpServers": {
    "cancel-my-sub-mcp": {
      "serverUrl": "https://goodturn-mcp.pages.dev/cancelmysub/mcp"
