Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Read-only travel eSIM catalog: search plans, fetch plan details, check availability, and get exact price quotes (USD cents). Plan results include a url where a traveler completes the purchase on the web. Purchasing through this server is not available yet and will require an approved partner token.

check_availability — Check plan availability
Advertised by the server during the last successful anonymous check.
Advertised read-only

Check whether a plan can be fulfilled right now for a given quantity, using the same gate the checkout runs. Returns available true/false; reason 'delisted' means the SKU left the catalog, 'unavailable' means it temporarily cannot be fulfilled.

90-day uptime

A lightweight connection check about every six hours, sampled on hosts with many listings. It shows the server answered, not that its tools work.

Too few checks for a percentage yet (1 of 1 answered).

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 zwitchy-mcp https://zwitchy.io/api/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 zwitchy-mcp --url https://zwitchy.io/api/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable zwitchy-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "zwitchy-mcp": {
      "url": "https://zwitchy.io/api/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
Cline configuration
{
  "mcpServers": {
    "zwitchy-mcp": {
      "type": "streamableHttp",
      "url": "https://zwitchy.io/api/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start zwitchy-mcp and inspect its tools.
VS Code configuration
{
  "servers": {
    "zwitchy-mcp": {
      "type": "http",
      "url": "https://zwitchy.io/api/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 zwitchy-mcp https://zwitchy.io/api/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://zwitchy.io/api/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": {
    "zwitchy-mcp": {
      "serverUrl": "https://zwitchy.io/api/mcp"
