Claude Code

Run this once in a terminal. It registers a Streamable HTTP server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http wem-price-compare-mcp https://wem3.ai/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 wem-price-compare-mcp --url https://wem3.ai/api/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable wem-price-compare-mcp in your MCP settings.

  "mcpServers": {
    "wem-price-compare-mcp": {
      "url": "https://wem3.ai/api/mcp"
    }
  }
}

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure). The type must be streamableHttp for a remote HTTP server.
