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 spacenexus-mcp https://spacenexus.us/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 spacenexus-mcp --url https://spacenexus.us/api/mcp

Cursor

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

Cursor configuration

{
  "mcpServers": {
    "spacenexus-mcp": {
      "url": "https://spacenexus.us/api/mcp"
    }
  }
}

Cline

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

Cline configuration

{
  "mcpServers": {
    "spacenexus-mcp": {
      "type": "streamableHttp",
      "url": "https://spacenexus.us/api/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start spacenexus-mcp and inspect its tools.

VS Code configuration

{
  "servers": {
    "spacenexus-mcp": {
      "type": "http",
      "url": "https://spacenexus.us/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 spacenexus-mcp https://spacenexus.us/api/mcp

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.

Claude Desktop configuration

{
  "mcpServers": {
    "spacenexus-mcp": {
      "url": "https://spacenexus.us/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": {
    "spacenexus-mcp": {
      "serverUrl": "https://spacenexus.us/api/mcp"
    }
