## TL;DR

### Why use Composio?
Apart from a managed and hosted MCP server, you will get:
- CodeAct: A dedicated workbench that allows GPT to write its code to handle complex tool chaining. Reduces to-and-fro with LLMs for frequent tool calling.
- Large tool responses: Handle them to minimise context rot.
- Dynamic just-in-time access to 20,000 tools across 1000+ other Apps for cross-app workflows. It loads the tools you need, so GPTs aren't overwhelmed by tools you don't need.

## Connect Linkup to Codex

### How to install Linkup MCP in Codex
### Run the setup command
Run this command in your terminal to add the Composio MCP server to Codex.

```bash
codex mcp add composio --url https://connect.composio.dev/mcp
```

## What is the Linkup MCP server, and what's possible with it?

The Linkup MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Linkup account. It provides structured and secure access to enterprise-grade web search and natural language answering, so your agent can perform actions like retrieving relevant information, answering questions, summarizing sources, and surfacing insights from the web on your behalf.
- Natural language question answering: Ask your agent complex or open-ended questions and get concise, sourced natural language answers pulled from web data.
- Structured web search and insights retrieval: Let your agent perform deep searches on any topic and return structured insights, detailed summaries, or raw search results as needed.
- Source-backed information synthesis: Get responses that include not just answers but citations to the original web sources, making it easy to verify and explore further.
- Customizable search depth and output: Have the agent adjust search precision, control answer format (summary, structured, or detailed search results), and even include images if your use case needs them.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `LINKUP_CREATE_RESPONSE` | Create Response | Proxy endpoint for OpenAI-compatible response generation. Used when the OpenAI client's base URL is set to Linkup. Supports 'linkup-standard' for faster results and 'linkup-deep' for more comprehensive results. |
| `LINKUP_FETCH_WEBPAGE` | Fetch Webpage | Fetch and retrieve a markdown representation of a webpage from a given URL. Supports optional JavaScript rendering for single-page applications, raw HTML extraction, and image extraction from the webpage content. Use this when you need to extract clean, structured content from web pages. |
| `LINKUP_GET_CREDITS_BALANCE` | Get Credits Balance | Tool to retrieve the current credits balance for your Linkup account. Returns the number of credits remaining that can be used for search and fetch operations. |
| `LINKUP_SEARCH` | Search Linkup | Search the web and retrieve insights using Linkup's API. This action provides three output modes: natural language answers with sources (sourcedAnswer), raw search context (searchResults), or custom structured JSON (structured). Supports filtering by date range and domains, with optional image results. Standard depth uses 1 credit, deep search uses 10 credits. Only indexes publicly available web content; private repositories and internal endpoints return no results. |

## Creating MCP Server - Stand-alone vs Composio SDK

The Linkup MCP server provides comprehensive access to Linkup operations through Composio. Once connected, you can perform all major Linkup actions directly from Codex using natural language commands.

## Conclusion

### Conclusion
You've successfully integrated Linkup with Codex using Composio's MCP server. Now you can interact with Linkup directly from your terminal, VS Code, or the Codex App using natural language commands.
Key benefits of this setup:
- Seamless integration across CLI, VS Code, and standalone app
- Natural language commands for Linkup operations
- Managed authentication through Composio
- Access to 20,000+ tools across 1000+ apps for cross-app workflows
- CodeAct workbench for complex tool chaining
Next steps:
- Try asking Codex to perform various Linkup operations
- Explore cross-app workflows by connecting more toolkits
- Build automation scripts that leverage Codex's AI capabilities

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Linkup MCP?

With a standalone Linkup MCP server, the agents and LLMs can only access a fixed set of Linkup tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Linkup and many other apps based on the task at hand, all through a single MCP endpoint.

### Can I use Tool Router MCP with Codex?

Yes, you can. Codex fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Linkup tools.

### Can I manage the permissions and scopes for Linkup while using Tool Router?

Yes, absolutely. You can configure which Linkup scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

### How safe is my data with Composio Tool Router?

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Linkup data and credentials are handled as safely as possible.
