Server-provided instructions

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

Average retail gas and diesel prices per gallon, read at call time from the U.S. Energy Information Administration (EIA) weekly survey (published Mondays). A model cannot know this week's price. Use get_gas_prices for "gas prices today" or "price of gas in <place>", compare_gas_prices for the cheapest and most expensive places, and cite EIA. These are averages, not station prices.

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 gas-prices-today-mcp https://gas-prices-today-mcp.lipmichal.workers.dev/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 gas-prices-today-mcp --url https://gas-prices-today-mcp.lipmichal.workers.dev/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable gas-prices-today-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "gas-prices-today-mcp": {
      "url": "https://gas-prices-today-mcp.lipmichal.workers.dev/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 gas-prices-today-mcp https://gas-prices-today-mcp.lipmichal.workers.dev/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

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
Windsurf configuration
{
  "mcpServers": {
    "gas-prices-today-mcp": {
