The Indices MCP server lets your AI agents perform tasks across the web. Connect it to any MCP-compatible agent in minutes. MCP endpoint: https://mcp.indices.io Authentication: All requests require an Authorization: Bearer <API_KEY> header. Generate an API key in the dashboard.

​
Installation

Use add-mcp to configure Indices across all your installed agents at once. In a terminal, run: 
npx add-mcp https://mcp.indices.io --header "Authorization: Bearer <API_KEY> --all -g -y"
add-mcp detects which agents you have installed (Claude Code, Cursor, VS Code, Gemini CLI, Codex, and more) and updates their config files automatically. Skill: Optionally, install the Indices skill to teach coding agents how to use Indices: npx skills add indicesio/skills --all --global

​
Claude Code

In a terminal, run: 
claude mcp add indices-mcp https://mcp.indices.io --transport http --header "Authorization: Bearer <API_KEY>"
For more information, see the Claude Code MCP documentation.

​
Claude Desktop

For Claude Desktop, go to Settings → Developer → Edit Config and add: 
{
  "mcpServers": {
    "indices-mcp": {
      "command": "npx",
      "args": [
        "mcp-remote",
        "https://mcp.indices.io",
        "--header",
        "Authorization: Bearer <API_KEY>"
      ]
    }
  }
}
For more details, see the Claude remote MCP documentation.

​
Cursor

Add to ~/.cursor/mcp.json or .cursor/mcp.json: 
{
  "mcpServers": {
    "indices-mcp": {
      "url": "https://mcp.indices.io",
      "headers": {
        "Authorization": "Bearer <API_KEY>"
      }
    }
  }
}

VS Code (Copilot)

Add to your settings.json: 
{
  "mcp": {
    "servers": {
      "indices-mcp": {
        "type": "http",
        "url": "https://mcp.indices.io",
        "headers": {
          "Authorization": "Bearer <API_KEY>"
        }
      }
    }
  }
}
For more details, see the VS Code MCP documentation.

​
Gemini CLI

Add to ~/.gemini/settings.json: 
{
  "mcpServers": {
    "indices-mcp": {
      "httpUrl": "https://mcp.indices.io",
      "headers": {
        "Authorization": "Bearer <API_KEY>"
      }
    }
  }
}
For more details, see the Gemini CLI MCP documentation.

​
ChatGPT

Go to Settings → Connectors → Advanced Settings, enable Developer Mode, then create a connector:
  • Name: indices-mcp
  • URL: https://mcp.indices.io
  • Authentication: Add the header Authorization: Bearer <API_KEY>
For more details, see OpenAI’s MCP apps documentation.

​
OpenAI Codex CLI

Add to ~/.codex/config.toml: 
[mcp_servers.indices-mcp]
url = "https://mcp.indices.io"

[mcp_servers.indices-mcp.headers]
Authorization = "Bearer <API_KEY>"
For more details, see the Codex MCP documentation.

​
Other agents

Use the Streaming HTTP transport with URL https://mcp.indices.io. Ensure outbound requests include the Authorization: Bearer <API_KEY> header. If your client doesn’t support custom headers, use mcp-remote to proxy requests. See the MCP documentation for general guidance.
